加工钨钴硬质合金模一般使用圆锥形或菱形钢针以及磨粉 ,磨粉一般采用硬质材料或超硬质材料。磨模一般为针转动或拉丝模转动。磨模一般分为 3道工序 :粗磨、精磨、抛光。普通磨模工艺的缺点是 :(1 )生产效率低 (在 5～7ｍｉｎ内才能磨去 0 1ｍｍ) ;(2 )加工的几何尺寸准确度低 Tungsten carbide cobalt alloy die processing generally use conical or diamond needle and milling, milling generally use hard materials or super-hard materials. Grinding the mold is generally needle rotation or drawing mold rotation. Mold is generally divided into three processes: rough grinding, grinding, polishing. Disadvantages of ordinary grinding process are: (1) low production efficiency (0 1mm can be worn in 5 ~ 7min); (2) the machining accuracy is low
