为了解决薄壁壳体零件的加工问题,我们设计了机夹台阶式可转位端而铣刀,采用分层切削方式,减小了切削力,取得了较好的效果。一、加工零件存在的问题加工工件为传动箱体,材料HT20-40。该零件为薄壁型箱体,加上有伸展出的联接面,厚度只有12毫米,犹如伸展的翅膀,给加工带来困难。过去,采用一般端面铣刀加工,在铣削时产生较强的振动,简直无法加工,分析产生振动的原因:1.工件毛坯基准定位为三点定位,夹紧力较小;2.壁
In order to solve the processing problems of the thin-walled shell parts, we designed the machine folder step indexable milling cutter end, the use of stratified cutting method, reducing the cutting force, and achieved good results. First, the processing of existing parts of the workpiece The workpiece for the transmission box, material HT20-40. The part is a thin-walled case with an extended coupling, only 12 mm thick, extending like a wing, creating difficulties in machining. In the past, the use of general face milling cutter, milling produce strong vibration, simply can not be processed, analysis of the reasons for the vibration: 1. The positioning of the workpiece blank positioning for the three points, clamping force is small; 2. Wall
