数控刀具小编对于螺纹柄英制钴高速钢短麻花钻的制造成形，国内普遍采用热轧扭制工艺，其特点是用逐步成型扇形板热轧成直槽，然后扭制成螺旋槽，再进行加工至标准要求，该工艺的优点是生产效率高，能充分利用原材料，加工出的钻头坯体内部组织具有纤维连续性，且晶粒细化，碳化物分布均匀，红硬性高。

铣制工艺是传统的制造加工方法，其特点是用成型铣刀在尚未淬硬的麻花钻毛坯上铣制出符合要求的螺旋槽形状，然后经热处理后再加工至标准要求，该工艺的刀具费用高，加工时间长，而且在热处理前至加工到后面的形状时，在淬硬时产生的几何形状误差几乎全部反映到成品钻头上，质量波动性较大，铣制主要工艺流程:落料→接柄→车加工→铣槽→粗抛槽→清边→去毛刺→热处理→精加工。
