        本文 main/primary mold manufacturing most 常出现 25 issues, main/primary is about/regarding 切削方面, 并一一做出 understanding 答

        1. selection mold what is most important and most tool has property factors?

        答: formed methods － can from types basic material type type in selection.

        A) hot processing tool 钢, it can 承受模铸, and pressure versus for high temperature degree.

        B) cold processing tool 钢, it used for lower material and 剪切, cold formed 形, cold pressure, cold and powder add pressure formed 形.

         plastics -一 plastics generate property product, 例如PVC plastics. long time 停工引起 cold 凝, property gas 体, acid, cooling / add hot, water or conditions and other factors generate 腐蚀. in this lower, recommendation use 不锈钢材 material 钢.

         dimensions - large dimensions use hard 钢. overall hard 钢常常 used for small dimensions.

         use 次数 - long use (> 1 000 000次) use high hardness 钢, its hardness is 48-65 HRC. in and other long time use (100 000 to 1 000 000次) use hard 钢, its hardness is 30-45 HRC. short time use (<100 000次) use soft 钢, its hardness is 160-250 HB.

         surface coarse degree - many plastics manufacturing for good surface coarse degree 感兴趣. add improvement metal property can 时, surface quality therefore decline. content high 钢也变 more 脆.

        2. effect/influence material can property need factors is what?

        答: chemical formed separation very important. alloy formed separation high, difficult processing. carbon content increase 时, metal property can decline.

        钢 structure for metal property can non important. different structure 包括: 锻造, 铸造, pressure, made and already processing. parts and parts has non difficult processing surface.

         hardness is effect/influence metal property can important factors. generally is hard, difficult processing. high speed 钢(HSS) can used for processing hardness most high is 330-400 HB material; high speed 钢+ titanium nitrogen (TiN) coating, can processing hardness most high is 45 HRC material; for/regarding hardness is 65-70 HRC material, must use hard alloy, 陶瓷, metal and nitrogen 化硼(CBN).

         non metal generally for tool lifespan has defect effect/influence. 例如Al2O3 (oxidation aluminum), it is pure 陶瓷, has very strong/high abrasion property.

         most rear is residual stress, it can metal property can issues. recommendation in coarse processing rear 进行应 force 释放工序.

        3. mold manufacturing production cost which separation formed?

        答: coarse 略 说, cost distribution 情况如 lower:

        切削 65%

        工 parts material 20%

         hot 处理 5%

         assembly / adjustment 10%

         this non 常清楚 table/sheet 明 良 good metal property can and excellent 良 总体切削 solutions for production important property.

        4. iron features is what?

        答: generally 说, it is:

        铸 iron hardness and strong/high degree high, metal property can low, from sheet/slice and tool can lifespan low. used for metal production iron its large classification type metal property can generally very good. metal property can and structure has 关, relatively hard light iron its processing difficult degree relatively large. sheet/slice 状石墨铸 iron and can iron has excellent 良 切削 property, 而球墨铸 iron versus 当差.

         processing iron to main/primary abrasion loss type type is: abrasion 蚀, adhesion and expand dispersion abrasion loss. abrasion main/primary carbon material, 沙粒参杂 material and hard table/sheet generate. has 积屑瘤 adhesion abrasion loss in low temperature degree and speed degree conditions lower 发生. iron iron 素体部 separation most easy welding to sheet/slice upper, this can use improve/increase speed degree and temperature degree 克服.

         in 另一方面, expand dispersion abrasion loss and temperature degree has 关, in high speed degree generate, especially is use high strength iron grade 时. this grade has very high resistant type can force, high temperature. this type of abrasion loss and iron and tool between function has 关, this make 一 铸 iron use or nitrogen 化硼(CBN)刀 tool in high speed lower processing, obtain good tool lifespan and surface quality.

         generally for processing iron requirements type tool property is: high hot hardness and chemical stability property, and 工序, parts and conditions has 关; requirements 切削刃 has tough property, heat resistant fatigue abrasion loss and strong/high degree. 切削铸 iron 满意程 degree 取决于切削刃 abrasion loss how to development: fast speed 变钝意味 generate hot cracks and 缺口而 make 切削刃 早 fracture, parts loss, surface quality 差, large degree and other. positive rear abrasion loss, unchanged and 锋利 切削刃 positive is generally need force to.

        5. what is mold manufacturing in main/primary, processing 工序?

        答: manufacturing need 经 切削 process, its in less separation is 3 工序 type type:

         coarse processing, semi processing and processing, has 时甚至 also has ultra- 精 processing (large separation is high speed application). amount 铣削当然 is in semi processing rear is processing 而准备. in 每一 工序 in 都应努 force to is lower 一 工序留 lower uniform distribution amount, this non important. if tool direction and as negative very less has fast speed 变化, tool lifespan can can long, more add can forecast. if can can, in specialized machine upper 进行精 processing 工序. this in more short debugging and assembly time inner improve/increase 几何精 degree and quality.

        6. in this different in main/primary use types tool?

        答: coarse processing 工序: sheet/slice 铣刀, 球头立铣刀 and large 刀尖圆弧 semi 径 立铣刀.

         semi processing 工序: sheet/slice 铣刀(直径 scope/range is 10-25 mm sheet/slice 铣刀), 球头立铣刀.

        精 processing 工序: sheet/slice 铣刀, 球头立铣刀.

        残余 amount 铣削工序: sheet/slice 铣刀, 球头立铣刀, 直立铣刀.

         through selection 专门 刀 tool dimensions, and grade combined, and parameters and combined 适 铣削策略, optimization process, this non important.

        7. in process in has has most important factors?

        答: process in most important target/goal is in 每一 工序 in is types tool uniform distribution processing amount. this is 说, must use different 直径 刀 tool (from large to small), especially is in coarse processing and semi processing in. 任何时候 main/primary standards is in 每 工序 in and most 终形状尽 can can versus 近.

         is types tool provide uniform distribution processing amount ensure 恒定而 high production rate and safety process. 当ap/ae(轴 toward deep degree /径 toward deep degree)不变时, speed degree and to rate can maintain in relatively high water upper. this 样, 切削刃 upper machine function and as negative 载变化就 small, therefore generate hot amount and fatigue less, from improve/increase tool lifespan. if rear 面 工序 is semi processing 工序, especially is has processing 工序, can 进行无人 processing or separation processing. 恒定 材 material processing amount is high speed application basic standards.

        恒定 processing amount has 利 效应 is for machine 床——导轨, filament and bearings effect/influence small.

        8. is what most will sheet/slice as is mold coarse processing tool 首选?

        答: if use 方肩铣刀进行 type coarse 铣削, in semi processing in need remove a large amount of 台阶状切削余 amount. this will make force 发生变化, make tool bending. its is to processing lower non-uniform processing amount, from effect/influence 几何精 degree. if use strong/high degree relatively low 方肩铣刀(belt/tape 三角形刀 sheet/slice), generate can forecast 切削效应. 三角形 or 菱形刀 sheet/slice also generate more large toward force, and due to sheet/slice 切削刃 数 amount relatively less, therefore is property relatively coarse processing tool.

        另一方面, sheet/slice can in various material in and direction upper 进行铣削, if use it, in versus 邻刀路 between relatively slip, can is semi processing lower relatively small and relatively uniform processing amount. sheet/slice features is generate thick degree is can 变. this make it can use ratio large more its it sheet/slice more high to rate. sheet/slice 主偏角 from is 零(non shallow 切削)改变 to 90 degree, function non 常平稳. in most large deep degree 处, 主偏角 is 45 degree, belt/tape outer 圆 直壁仿形切削时, 主偏角 is 90 degree. this 也说明 is what sheet/slice tool strong/high degree large ——切削 negative is increase large. coarse processing and semi coarse processing 应该总 will sheet/slice 铣刀, 如CoroMill 200(见 manufacturing 样本C-1102:1) as is 首选. in 5轴切削 in, sheet/slice non combined, especially is it has 任何限 made.

         through use good 编程, sheet/slice in very large degree upper can 代替球头立铣刀. amount small sheet/slice and abrasion, positive front and light 切削槽形 versus combined, can used for semi processing and 一 精 processing 工序.

        9. what is has 效切削 speed degree (ve) and is what it for high production rate non important?

        答: in, or has 效直径 upper has 效切削 speed degree basic 计算总 is non important. due to 台面进 to amount 取决于一定切削 speed degree lower speed, if 未计算 has speed degree, 台面进 to amount 就会计算错误.

         if in 计算切削 speed degree use tool 名义直径 value (Dc), 当切削 deep degree shallow 时, has or 实际切削 speed degree need ratio speed degree low more. 如圆刀 sheet/slice CoroMill 200刀 tool (especially is in small scope/range), 球头立铣刀, large 刀尖圆弧 semi 径立铣刀 and CoroMill 390立铣刀之 type tool (this tool 请参见山特维克 can manufacturing C-1102:1). 由此, to to rate low more, this heavy reduce production rate. more important is, tool conditions low it can force and recommendation application scope.

        当进行3D切削时, 切削时 直径 in 变化, it and 几何形状 has 关. issues solutions is 定义 陡壁区域 and 几何形状 shallow parts 区域. if for 每 区域编 made CAM程序 and parameters, can to good in and 结果.

        10. for/regarding formed 功 淬 hard mold 钢铣削 说, important application parameters has which?

        答: use high speed for hard 钢进行精 processing 时, 一 需遵守 main/primary factors is using/adopting shallow 切削. deep degree ultra- 0.2/0.2 mm(ap/ae: toward deep degree /径 toward deep degree). this is is 避免刀柄/切削刀 tool large bending and maintain processing has small and high degree.

         selection rigid property very good system and tool non important. use overall hard alloy tool 时, using/adopting has most large core 直径(most large resistant rigid property) tool non important. strip/profile experience method is, if will tool improve/increase 20%, from 10 mm improve/increase to 12 mm, tool bending will decrease small 50%. can 说, if will tool 悬伸/伸出部 separation shrink short 20%, tool bending will decrease small 50%. large and degree 刀柄进一步 improve/increase rigid degree. use can 转位刀 sheet/slice 球头立铣刀(见 manufacturing C-1102:1)时, if use overall hard alloy manufacturing, resistant rigid property can improve/increase 3-4倍.

        当 use high speed for hard 钢进行精 processing 时, selection specialized and grade non important. selection 像TiAlN this has high hot hardness coating non important.

        11. what 时候应 using/adopting 顺铣, what 时候应 using/adopting 逆铣?

        答: main/primary is: can can more use 顺铣.

        当切削刃 rigid 进行切削时, in in, thick degree can to its most large value. in in, is most small value. generally 说, in in tool lifespan ratio in in short, this is is in in generate hot amount ratio in in obvious high. in in 当切屑 thick degree from increase to most large 时, due to 切削刃受 to scratch ratio in in strong/high, therefore generate more more hot amount. in toward force obvious high, this for bearings has effect/influence.

         in in, 切削刃 main/primary to is pressure shrink force, this and in generate force versus ratio, for hard alloy sheet/slice or overall hard alloy tool effect/influence has more. 当然也 has outer. use overall hard alloy 立铣刀(见样本C- 1102:1 in tool)进行侧铣(精 processing)时, especially is in hard material in, is 首选. this more easy obtain more small 公差 壁直线 degree and more good 90 degree 角. different toward between if has heavy combined 话, 接刀痕也 non small. this main/primary is is force direction. if in in use non 常锋利 切削刃, force toward will 刀“拉” toward material. can use 逆铣 另一 例子 is, use 老式手动铣床进行铣削, 老式铣床 filament has relatively large 间隙. generate remove 间隙 切削 force, make 铣削动 as more 平稳.

        12.仿形铣削 also is and other high 线切削?

        答: in type 腔铣削 in, ensure 顺铣刀 tool formed most good methods is using/adopting and other high 线铣削路径. 铣刀(例如球头立铣刀, manufacturing 样本C-1102:1) outer and other high 线铣削常常 to high production rate, this is is in relatively large tool upper, has more more in 切削. if machine 床主轴 转 speed to made, and other high 线铣削 will maintain speed degree and to rate. using/adopting this type of tool 路径, as negative and direction 变化也 small. in high speed application and hard material processing in, this especially important. this is is if speed degree and to amount high 话, 切削刃 and process more easy to as negative and direction 改变 不利 effect/influence, as negative and direction 变化会引起切削 force and tool bending 变化. can can 避免沿陡壁 仿形铣削. lower 仿形铣削时, low speed degree lower thick degree large. in 球头刀 in 央, also has 刃口崩碎 危险. if control 差, or machine 床无预读 function, can fast decrease speed, most easy in in 央发生刃口崩碎 危险. 沿陡壁 upper 仿形铣削 for process relatively good 一, this is is in has 利 切屑 speed degree lower, thick degree is its most large value.

         is to most long tool lifespan, in process in make 切削刃尽 can can long time maintain 连续切削. if tool and 退出太 frequency 繁, tool lifespan obvious shrink short. this make 切削刃 upper hot force and hot fatigue add 剧. in 切削区域 has uniform and high temperature degree ratio has large for hard alloy tool more has 利. 仿形铣削路径常常 is and mixed combined (之字形), this 意味切削 in frequency 繁 吃刀 and 退刀. this type of tool for quality has good effect/influence. 每次吃刀意味刀 tool bending, in surface upper has 抬起 标记. tool 退出时, force and tool bending decrease small, in 退出部 separation has light micro material “ 切削”.

        13. is what has upper must has different 齿距?

        答: is more 切削刃刀 tool, 齿数(z) is can 改变, has factors can 帮助确定 used for different processing type type or 齿数. material, parts dimensions, stability property, dimensions, surface quality requirements and can use rate is and processing has factors. and tool has factors 包括足够 每齿进 to amount, less meanwhile has 两 齿 in 切削以 and tool 切屑容 amount, this is its in small separation.

        铣刀 齿距(u) is sheet/slice 切削刃 upper to lower 一 切削刃 upper 同一 点 距离. separation is hydrophobic, and ultra- 密齿距铣刀, large separation can 乐满铣刀都 has this 3 选项, manufacturing 样本C-1102:1. 密齿距 is has relatively more and 适当 容屑空间, can high metal remove rate 切削. generally used for iron and in and other negative 载铣削. 密齿距 is general purpose 铣刀 首选, recommendation used for mixed combined production.

         hydrophobic is in 铣刀圆周 upper has relatively less and has large 容屑空间. hydrophobic 齿距常常 used for coarse processing to processing, in processing in for processing effect/influence very large. hydrophobic is true positive has issues solutions, it is long 悬伸铣削, low rate machine or its it must decrease small force application 首选.

         ultra- 密齿距刀 tool 容屑空间 non small, can use relatively high as to. this tool combined 于间断 铸 iron surface 切削, iron coarse processing and small amount 切削, 例如侧铣. it 们也适 combined must maintain low speed degree application. also can has uniform or and other 齿距. rear is tool upper 齿 间隔不 versus and other, this is solution issues has methods.

        当存 in issues 时, recommendation can can using/adopting hydrophobic and other 齿距铣刀. due to sheet/slice less, add can can property small. small tool 直径也 can improvement this type of 情况. use can very good 适应 槽形 and grade combined ——锋利 切削刃 and tough property good grade combined.

        14. is obtain most property can, 铣刀应 how to 定位?

        答: long degree to 铣刀位置 effect/influence. tool lifespan and 切削刃必 must 承担 切削 long degree has 关. 定位于工 parts in 央 铣刀 its long degree short, if make in direction in 心线, 切削 弧就 long. need 记住, force is how to function, must to 一 折 in. in tool 定位于工 parts in 央 情况 lower, sheet/slice 切削刃进入 or 退出切削时, toward force direction 就随之改变. machine 床主轴 间隙也 make add 剧, 导致刀 sheet/slice 振动.

         through make tool in 央, to and has 利 切削 force direction. 悬伸越 long, has can can 振动也就越 important.

        15. is remove process in 振动, 应采取 what measures?

        答: in issues 时, basic measures is decrease small force. this can through use positive 确 刀 tool, methods and parameters to.

        遵守 lower already has 效 建议:

        - selection hydrophobic or and other 齿距铣刀.

        - use positive front 角, small force sheet/slice 槽形.

        - 尽 can can use small 铣刀. use decrease 震接杆进行铣削时, this especially important.

        - use small 切削刃钝化 semi 径(ER) sheet/slice. from thick coating to thin coating. need can use non coating sheet/slice. use is fine pellets high toughness sheet/slice grade.

        - use large 每齿进 to. reduce speed, maintain as to amount (and other relatively large 每齿进 to amount). or maintain speed improve/increase as to amount (relatively large 每齿进 to amount). decrease small 每齿进 to amount!

        - decrease small toward and toward deep degree.

        - selection stability 刀柄, can 乐满Capto. use can can large dimensions, obtain most stability property. use degree add long 杆, obtain most large rigid property.

        - for/regarding large 悬伸, use and hydrophobic 齿距不 and other 齿距铣刀结 combined decrease 震接杆. 安装铣刀时, make and decrease 震接柄直接连接.

        - make 铣刀偏离工 parts in 心.

        - if use 偶数齿 刀 tool —— can 每隔一齿拆 lower 一 刀 sheet/slice.

        16. is make tool balanced, 应采取 most important measures has which?

        答: in 整 切削 process in, is to tool balanced to type steps lower:

        - 测 amount tool /刀柄组 parts balanced.

        - through more tool, it remove quality, or 移动刀柄 upper heavy reduce balanced.

        - 经常必 must heavy this steps, again 次检查刀 tool, again 次精确 adjustment, to to balanced.

        刀 tool balanced also to several 未讨论 process in unstable property. its in is and between combined issues. its causes is 夹紧时常常 has can amount 间隙, can can is upper has or 脏污. this formed 锥柄每次定位都不 same. make tool, and in 各 方面 状态都 very good, if in 沾污, 也会造 formed balanced. is balanced tool, must increase process in cost, if tool balanced for reduce cost non important, 就应并 for types specific 情况进行 analysis.

        但 is, is very good balanced tool, in selection positive 确 刀 tool also has many as need 做. below/following is selection tool to 予考虑: - 购买 high quality tool and 刀柄. selection already remove balanced 刀柄.

        - most good use short and can can light tool.

        - 定期检验刀 tool and 刀柄, is has fatigue and deformation 征兆.

         process can 接受 刀 tool balanced process 自身 情况 确定. this 情况包括切削 process force, machine balanced and this factors versus effect/influence degree. experiment/testing is to most balanced most good methods. use different balanced value 运行几次, from balanced value is 20克 mm or more low 开始. 每次运行 rear, again use more add balanced tool heavy experiment/testing. most balanced is this 样 一 点: ultra- this rear, 进一步 improve/increase tool balanced improve/increase parts surface quality; or is this 样 一 点: in upper process can easy ensure 规定 工 parts 公差.

         key/critical is will focus/key point in process upper, is will balanced and other grade -G value or its it 任意确定 balanced value as is target/goal. target/goal is to efficiency can can high process. this to 权衡刀 tool balanced cost and therefore obtain benefits, therefore in cost and benefits between combined 理 进行 balanced.

         about/regarding tool balanced more detailed technology 信息, and can 乐满代 table/sheet 联系.

        17. in and high speed application in, is to can can good 效果, use types 刀柄?

        答: high speed processing 时, force non large, 会导致主轴孔 slow slow large. this for V形 method 兰 刀柄会 generate negative effect/influence, is V形 method 兰 刀柄仅 in toward upper and 主轴孔接触. 主轴孔变 large make tool in 拉杆恒定 拉 force function lower by 拉入主轴. this 甚至会引起刀 tool viscous or Z轴 direction dimensions degree reduce.

         and 主轴孔 and meanwhile 接触 刀 tool, toward and toward meanwhile combined tool more suitable for high speed lower 切削. 当主轴孔 expand large 时, 端面接触 can 避免刀 tool in 主轴孔 inner toward upper 移动. use 空心刀柄 刀 tool easy 受离心 force effect/influence, it already design formed in high speed lower 随主轴孔 increase large increase large. tool and in toward and toward 都接触 provide good rigid property, make tool can high speed 切削. using/adopting has 椭圆三棱 short design can 乐满Capto接口 in 传递扭矩 and high production rate 切削时, tool has more excellent property can.

         high 主轴转 speed 时主轴 surface Comparison Table

        主轴转 speed ISO 40 HSK 50A Coromant Capto C5

        0 100% 100% 100%

        20 000 100% 95% 100%

        25 000 37% 91% 99%

        30 000 31% 83% 95%

        35 000 26% 72% 91%

        40 000 26% 67% 84%

        当安排 high speed 切削时, amount use for 称 刀 tool and 刀柄组 combined formed tool system. has types can use different tool system. will add hot make expand 张, it cooling rear tool by 夹紧, this is combined system. for/regarding high speed 切削 说, this is most good and most can solid tool methods. this is is it amount non small;第二, this type of can large 扭矩;第三, it very easy 构建定 made tool and tool parts; most rear, use this type of methods formed tool parts has high rigid property.

        另一 types 出众并 non general purpose tool plant/unit is can high degree strong/high force 夹头——CoroGrip. this type of system cover/cap from coarse processing to ultra- 精 processing has application. 一 夹头 can use 直柄, 惠氏刻槽 or pressure 式刀柄 面铣刀 to has type type tool. standards elastic sleeve/set, can use liquid pressure (HydroGrip), BIG, Nikken, NT elastic sleeve/set, can used for CoroGrip夹头. in 4XD处 跳动 amount is 0.002 – 0.006 mm. force and 扭矩传递 especially high, its balanced design make it used for high speed 切削(< 40 000转/ separation)时 has non 常完美 property can. about/regarding detailed 信息, 请参见 manufacturing 样本C-1102:1.

        18. how to 切削转角才 can has 振动 危险?

        答: 传统 切削转角 methods is use property 切削(G1), in 转角 渡不连续. this is 说, tool to 达角落时, due to property 轴 动 force features made, tool must decrease speed. in electrical machine 改变进 to direction front, has short 暂 停顿, this generate a large amount of hot amount and scratch. very long long degree 会导致切削 force unstable, 并常常 make 角落切削不足. type is 振动——刀 tool large and long, or tool 总悬伸越 large, 振动越 strong/high.

        此 issues most solutions:

         use semi ratio semi small tool. use 圆弧插补生 formed 角落. this type of processing methods in block 边界处不会 generate 停顿, this is 说, tool provide light slip and 连续 渡, generate can can property large large reduce.

        另一 types solutions is through 圆弧插补 generate ratio upper 规定稍 large semi 径. this is very has 利, this 样, has can in coarse processing in use relatively large tool, maintain high production rate.

         in 角落处余 lower processing amount can using/adopting relatively small tool solid 定铣削 or 圆弧插补切削.

        19. what is 开始切削 type most methods?

        答: has 4 types main/primary methods:

        起始孔 预钻削, 角落也 can 预钻削. recommendation this type of methods: this need increase types tool, meanwhile tool need 占据刀 tool inner 空间. mono from 切削 观点看, tool through 预钻削孔时因切削 force generate 不利 振动. use 预钻削孔时, 常常会导致刀 tool loss bad. use 预钻削孔, increase again 切削.

         if use 球头立铣刀 or sheet/slice tool (见 manufacturing 样本C-1102:1), usually using/adopting 啄铣, ensure full toward deep degree can 以切削. use this type of methods disadvantages is issues and use sheet/slice generate non long 切屑.

         most methods is use X/Y and Z direction property 坡走切削, to full toward deep degree 切削.

         most rear, can 以螺旋形式进行圆插补铣. this is types non good methods, is it can generate light slip function, requirements very small 开始空间.

        20. high speed 切削 定义 is what?

        答: for/regarding high speed 切削 讨论 in 一定程 degree upper still is mixed 乱. how to high speed 切削(HSM), currently has many and many methods. let 我们看一 lower this in several:

         high speed degree 切削

         high speed degree 切削

         high to 切削

         high speed and high to 切削

         high production rate 切削

        我们 for high speed 切削 定义描述如 lower:

        HSM不 is simple upper high speed degree. it by is is use methods and production equipment processing process.

         high speed 切削无需 high speed 主轴切削. many high speed application is in and other speed 主轴并 using/adopting large dimensions tool 进行.

         if in high speed degree and high to conditions lower for hard 钢进行精 processing, parameters can is 常规 4 to 6倍.

         in small dimensions parts coarse processing to semi processing, processing and dimensions parts ultra- 精 processing in, HSM意味 high production rate 切削.

         parts 形状变 越 越 complex, high speed 切削也就显 越 越 important.

        现 in, high speed main applications degree 40 machine upper.

         about/regarding high speed detailed 信息, 请参见 manufacturing application guide C-1120:2. 请参见 manufacturing application guide C-1120:2.

        21. high speed target/goal is what?

        答: high speed main/primary target/goal is through high production rate reduce production cost. it main applications processing 工序, is used for processing hard 钢. target/goal is through shrink short production time and time improve/increase overall competition force.

        达 to this target/goal main/primary factors is:

         one-time (more less 此数)装夹 processing.

         through improvement 几何精 degree, meanwhile can decrease/reduce 手工劳动 and shrink short mold trial time.

         use CAM system and toward workshop 编程 帮助 made process plan, through process plan improve/increase machine and workshop utilizing rate.

         about/regarding high speed detailed 信息, 请参见 manufacturing application guide C-1120:2. 请参见 manufacturing application guide C-1120:2.

        22. high speed 切削 实际 advantages is what?

        答: tool and parts can maintain low temperature degree, this in many lower long tool lifespan. 另一方面, in high speed application in, amount is shallow, 切削刃 吃刀 time especially short. this is 说, to ratio hot time fast.

         low force to small 而一致 刀 tool bending. this and types tool and 工序 需 恒定 processing amount versus combined, is high and safety processing conditions 之一.

         due to high speed in type deep degree is shallow, tool and upper toward force low. this decrease/reduce bearings, and filament abrasion loss. high speed and toward 铣削也 is good combined, it for bearings impact small, use this type of methods can use relatively long tool 而振动 风险不 large.

         small dimensions parts high production rate 切削, coarse processing, semi processing and processing, in 总 材 material remove rate versus for low has very good property.

         high speed can in generally processing in obtain high production rate, can obtain surface quality. surface quality low 于Ra 0.2 um.

         using/adopting high speed 切削, make for thin parts formed is can can. use high speed 切削, time short, impact and bending decrease small.

         几何精 degree improve/increase, 组装就容 easy and more fast. is what 人, can how to, can obtain CAM/CNC production surface and 几何精 degree. if in upper time more 一, 费时 人工抛 light as can decrease/reduce. can decrease/reduce 达60-100%

        一 processing, 如淬火, electrical understanding processing and electrical processing (EDM), can large large decrease/reduce. this can reduce investment cost and rear supply. use 切削代替 electrical processing (EDM), use lifespan and quality to improve/increase.

         using/adopting high speed 切削, can through CAD/CAM very fast design, especially is in need production new electrical 极 情况 lower.

         about/regarding high speed detailed 信息, 请参见 manufacturing application guide C-1120:2. 请参见 manufacturing application guide C-1120:2.

        23. high speed has or disadvantages 吗?

        答: due to process has high accelerated degree and decrease speed degree and 停止, 导轨, filament and bearings generate versus for fast abrasion loss. this 常常导致 relatively high cost.

         need process Knowledge, equipment and fast speed data 接口.

         can can very difficult to and high grade technology 员工.

        常 has versus long debugging and fault/failure time.

         processing in 无需紧急停止, 导致人 is and soft parts or hard parts fault/failure generate many heavy rear 果.

        必 must has good processing plan ——“ toward machine provide material ”.

        必 must has safety measures: use belt/tape safety outer and anti sheet/slice cover/cap machine 床. 避免刀 tool large 悬伸. need use “ heavy ”刀 tool and 接杆. 定期检查刀 tool, and is has fatigue cracks. use most high speed degree tool. need use overall high speed 钢(HSS)刀 tool!

         about/regarding high speed detailed 信息, 请参见 manufacturing application guide C-1120:2. 请参见 manufacturing application guide C-1120:2.

        24. high speed for machine has which requirements?

        答: for ISO/BT 40号 machine 床 典 type requirements lower:

        主轴 speed degree scope/range < 40 000 转/ separation

        主轴功 rate > 22 kW

        25. high speed for 切削刀 tool type features or requirements has which?

        答: overall hard alloy:

         high degree abrasion 削, toward low 于3 micron.

        尽 can can small and 悬伸, most large rigid property, can can small tool bending deformation and large 芯核直径.

         is make 振动 风险, force and bending can can small, 切削刃 and long degree can can short.

         ultra- dimensions, degree 刀柄, this in small 直径时 especially important.

         fine 晶粒基体 and is to high wear resistance TiAlN coating.

         used for cold or cooling liquid inner cooling 孔.
