        一, rigid wire drawing processing methods  

        1. for rigid abrasion 两 支撑面 and 观察面 rear 进行各工序 processing, it advantages is can utilizing rigid transparent property 观察开孑L and other processing process. it disadvantages is need abrasion separation rigid 石;金 rigid fine small, processing solid very 不方便. processing small 直径模孔时 use this type of methods.

        2.先 金 rigid and has powder 末烧结 formed block, sleeve/set rear 进行各工序 processing. method disadvantages is can 直接观察模孔 processing process, it advantages is ratio front types methods less abrasion 掉2/3~4/5 金 rigid 石;容 easy in 心, processing as 模方便,常 used for processing large 直径金 rigid 石模孔. rigid in use in, in surface generate strip/profile 纹, viscous metal, abrasion loss 呈椭圆形, belt/tape increase large and other defect 时, need heavy abrasion, increase large 模孔直径 rear heavy new use. heavy abrasion can more 次进行,一直 to rigid 石发生 cracks is 止.

        二, hard alloy wire drawing processing methods

         main/primary use machine abrasion processing method,工序如 lower: selection material →镶 sleeve/set →工 as abrasion light → lubricated abrasion light → export 锥(区) abrasion light →定径 belt/tape abrasion light → 渡区 abrasion light →工 as light →定径 belt/tape light →检查验收.

         in addition also has chemical machine abrasion processing method, ultra- 声波 processing method, electrical method processing method, electrical understanding liquid processing method and other. in wire drawing process in, hard alloy 模模孔因 abrasion loss generate 沟痕, 椭圆形, surface viscous metal and other defect, need heavy abrasion, expand large 模孔直径 to 邻近 模孔 dimensions use. heavy abrasion can more 次,直 to decrease small to cracks is 止.
