high speed filament 线切割 machine 床 断 filament causes analysis 　　 high speed filament 线切割 machine combined processing various complex 形状 冲模 and mono parts gears, 花键, narrow type parts, tool has speed degree fast, cycle short and other advantages, application non and. high speed filament 线切割 machine electrical filament main/primary is using/adopting filament, electrical filament speed degree fast usually is 8~12米/秒, but also is di toward 往返循 ring 运行, in processing process in very easy 发生断 filament. if in 切割工 parts process in more filament, not only formed 一定 经济 loss 失, but also belt/tape heavy new filament 麻烦; not only time, but also in parts upper generate filament 痕迹, effect/influence processing quality, heavy formed parts waste. 　　本文 detailed summary high speed filament 线切割 machine in as in 经常出现 断 filament causes and solutions: 　　1钼 filament 　　钼 filament 松紧程 degree. if filament 安装太松, filament 抖动厉害, not only formed filament, but also due to filament 抖动直接 effect/influence parts surface coarse degree. filament can 安装 太紧, internal stress increase large, 也会造 formed filament, therefore filament in process in, its 松紧程 degree need 适当, new 安装 钼 filament, need filament again processing, filament use force need large. filament in processing time rear, due to tensile 而变松. long amount relatively large 时, add filament or 出现钼 filament in filament upper heavy 叠. make filament 不稳而引起断 filament. 应经常检查钼 filament 松紧程 degree, if in phenomenon, need and 时拉紧. 　　钼 filament 安装. filament need 按规定 走 toward in filament upper, meanwhile solid 定两端. filament 时, generally filament 筒两端各留10mm, in 间绕满不 heavy 叠, wide degree less filament long degree semi, electrical machine toward frequency make machine parts accelerated loss bad, anti filament frequency and 切割而断 filament. 　　 machine upper filament 引出处 has filament rod, filament rod is 由两根红宝石 made formed toward 立柱, filament rod 不像导轮 that as 滚动运动, 他们直接 and filament 接触, as sliding scratch. therefore abrasion loss very fast, use 不久柱体 and filament 接触 方就会形 formed deep 沟, must and 时检查并进行翻转 and more 换, 否则会出现叠 filament filament. 　　2运 filament machine 　　线切割 machine filament machine main/primary is filament 筒, and 导轮组 formed. filament machine 构 精 degree decline 时(main/primary is bearings), 会引起贮 filament 筒 径 toward and toward 窜动. filament 筒 径 toward 跳动会 make electrical filament force decrease small, formed filament 松, heavy make filament from 导轮槽 in 脱出拉断. filament 筒 轴 toward 窜动会 make filament 不匀, generate filament phenomenon. filament 筒 轴 and bearings and other parts abrasion loss generate 间隙, easy filament 抖动而断 filament, therefore must and more abrasion loss and bearings and other parts. filament toward 时, has high frequency electrical 源, 会导致钼 filament in short time inner temperature degree high 而烧断钼 filament, therefore must 检查贮 filament rear 端 行程开关 is 否失灵. need maintain filament 筒, 导轮转动灵 active, in 往返运动时会引起运 filament system 振动而断 filament. filament rear 空载走 filament 检验钼 filament is 否抖动, 若发生抖动 need analysis causes. filament rear 端 限位挡 block must adjustment good, 避免贮 filament 筒冲出限位行程而断 filament. filament plant/unit in block and fast speed 运动 钼 filament 接触, scratch, easy generate 沟槽并造 formed filament 拉断, therefore and more 换. bearings abrasion loss will effect/influence filament degree, in addition, 当导轮 V type 槽, 宝石限位 block, conductive block abrasion loss rear generate 沟槽, make electrical filament scratch force large, easy will filament 拉断. this type of phenomenon generally in machine use time relatively long, processing parts relatively thick, filament machine easy 清理 情况 lower. therefore in machine use in 应定期检查运 filament machine 构 精 degree, and more easy abrasion loss parts. 　　3工 parts 　　工 parts material: for 不经锻打, 不淬火材 material, in 线切割 processing front most good using/adopting low temperature 回火消 remove internal stress, is if parts internal stress has to remove, in 切割时, has parts cracking, filament 碰断; has make deformation, filament or elastic 断. 如淬火 rear T8钢 in 线切割 processing in and easy 引起断 filament amount less use. thick aluminum material 时, due to 排屑困 difficult, conductive block abrasion loss relatively large, attention/notes and more 换. 　　工 parts 装夹: although 线切割 processing process in parts force small, still solid 夹紧工 parts, anti processing process in parts 位置变动造 formed filament. meanwhile need due to parts heavy and parts material elastic property deformation formed filament. in processing thick heavy parts 时, can in processing fast need 结束时, use magnetic iron will need lower 落 工 parts, or 者人工保护 lower 落 工 parts, make its 平行缓 slow lower from anti filament. 　　4 electrical parameters 　　 electrical parameters selection 不当也 is 引起断 filament important causes, therefore need according to parts thick degree selection combined electrical parameters, will 脉冲间隔拉开一, has 利于熔化 metal micro 粒 排出, meanwhile value electrical and electrical pressure high, make mono can amount large, speed degree add fast, easy generate in electrical and 拉弧, 引起断 filament. generally electrical pressure is 100V left right. in electrical processing in, electrical electrical is formed negative 极腐蚀 loss bad main/primary factors, again add upper 间隙不 combined 适, easy make certain 一脉冲形 formed electrical electrical, need electrical electrical in certain 一段, 就会引起断 filament. 　　 according to parts thick degree selection combined 适 放 electrical 间隙: electrical 间隙不 can small, 否则容 easy generate short 路, 也不利于 cooling and electrical material 排出; electrical large, will effect/influence surface coarse degree and processing speed degree. 当切割 thick degree relatively large parts 时, amount selection large wide electrical 流, meanwhile electrical 间隙也 need large 一点, long reinforcement 排屑效果, improve/increase stability property. 　　5结束语: 　　 above for high speed filament 线切割 machine filament causes analysis and to solutions, is according to long as experience summary 出. in 实际操 as process in, due to equipment, processing process, material formed filament causes also has very more, need in as in summary and improve/increase.
