Shanghai Daoqin Plastics Co., Ltd.

        一, abrasion light front 准备

        1, abrasion light 人员必 must training,并经考试 combined upper rear, can upper 岗.

        2, 明确工 parts process requirements,材 material and 初始状态,本工序 processing 部位, 形状, dimensions and light degree requirements.

        3, light front, must must light is has 塌边, 塌角, 切, deformation and and other defect and 留 抛 light amount is 否足够.

        4, based on process specification combined 理选取本工序 suitable tool, tool, 主, material.

        5, based on requirements for parts 进行适宜 anti 护.

        6, for 1—5 steps again rear as 业程序.

        二, parts and anti 护

        1, for/regarding 20Kg below/following relatively high or relatively long parts requirements in light as upper using/adopting 台钳装夹.

        2, for/regarding relatively large, relatively heavy parts must in light as upper using/adopting front rear magnetic iron, 螺钉夹码进行紧 solid.

        3, use as abrasion light parts 时, must using/adopting block or related measures ensure as solid, 保障工 as safety.

        4, for/regarding relatively small and type easy 碰伤, 碰花 工 parts must using/adopting sheet/plate type for type type 面进行保护.

        5, has 尖角, 棱角 工 parts must use 胶布, 胶纸进行保护, anti for and parts formed or loss 伤.

        6, for maintain and 封胶位 工 parts can in 暂不打 abrasion using/adopting sheet/slice (锯 sheet/slice or iron sheet/slice) or block solid 定保护 anti 棱边倒角, 倒圆.

        三, inner and scope/range

        1, 封胶面 is 否塌角, 倒圆;

        2, is bad 原出模斜 degree;

        3, 检查各抛 light dimensions, is ultra- 预留 amount;

        4, type 腔底部圆角 is 否凹进侧面 and 底面;

        5, is has phenomenon;

        6, its coarse degree is already 达图纸 requirements;

        7, combined rear, long (or 检验员)检查.

        四, light as precautions

        1, abrasion front 应检查打 abrasion amount is 否足够, abrasion light amount can ultra- 出预留 amount:

         abrasion rear 平面打 abrasion light amount can ultra- 出预留 amount 0.05～0.06mm;

        未 abrasion 削 面, electrical or 线切割 面打 abrasion light amount can ultra- 出预留 amount 0.08～0.1mm;

        筋位 mono and deep degree abrasion light amount can ultra- 出预留 amount 0.03～0.08mm.

        2, use light machine as high degree in attention/notes force, anti 出现沟槽, ultra- 余 amount, 不允许 long time in 同一部位 processing;

        3, one-time abrasion rear, must use 威士布清洁 dry 净, rear lower steps abrasion;

        4, one-time light rear, must use or soft scratch 净, rear lower 一步抛 light.

        5, in mold light front, 首先确定 processing 程序:

         according to different surface and coarse degree, 选取开始序位 and 需序位 combined 适 工序 and combined 适 工 tool (specific rigid 锉,#砂纸, 油石)

         according to mold type 腔 几何形状, coarse degree and process requirements features, power tools and abrasion tool use scope/range, force to for property processing

        6, need attention/notes 封胶面 打 abrasion light, especially is made parts 特殊标识符号 碰穿 and 封胶面部 separation can formed and 塌角现;

        7, abrasion light requirements ring 境整洁, in light process in attention/notes already light good 面 保护工 as;

        8, certain parts need assembly rear 一齐打 abrasion, 就不允许 mono abrasion;

        9, light 完, light 面自检, rear need upper anti 锈油, good 保护工 as, anti 碰伤, 刮花;

        10, various 油石, 砂纸, 钻石研 abrasion and rigid and other must its Model/Grade, specifications in has versus label 专门工 tool box/case inner.

        五, ultra- 声波抛 light machine

         applications lower:

        装夹烧结钻石锉 main/primary processing remove type inner 底平面, 侧平面 electrical processing 层;

        装夹 electroplating 钻石锉 remove narrow 平面, type 腔侧壁, and and other electrical processing and coarse 切削痕;

        装夹各 type 油石进行因 coarse processing formed 形位公差 修整 and improve/increase coarse degree;

        装夹 copper, soft hard 木并添 add various degree abrasion for processing achieve light.
