不锈钢薄壁锥套的加工有双重困难,3Cr13是一种中碳马氏体不锈钢,切削时容易产生加工硬化,切削难度较大,薄壁零件在径向夹紧力和径向切削力的作用容易变形,产生报废,特设计以内表面定心的弹性夹头(胀簧装置),作为专用夹具,合理选择刀具几何参数,数控编程时加工外圆锥时不采用G71循环,而采用G73进行环切。
Stainless steel thin-walled taper sleeve processing has two difficulties, 3Cr13 is a medium-carbon martensitic stainless steel, cutting easy to produce work hardening, cutting more difficult, thin-walled parts in the radial clamping force and radial cutting force Easy to deform, resulting in scrapped, specially designed to the inner surface of the center of the elastic chuck (expansion spring device), as a special fixture, a reasonable choice of tool geometry, CNC programming outer cone processing without G71 cycle, .
