挠性杆加工工艺

Machining Technology of Flexible Rod

本文针对挠性杆加工特点,扼要地介绍了国内、国外对挠性杆加工概况,确定了我们对挠性杆的加工工艺方案。经镗削、研磨的挠性杆装表后,性能稳定,达到了设计要求。特别是刀具的改进,由原来报废的中心钻手工磨制的刀具,改用微型机夹超细杜度硬质合金刀进行镗削,取得了良好效果,减少了加工时间,降低了成本。同时力求在今后的大批量生产过程中,使其工艺方法更加完善。

The paper describes machining characteristics of a flexible rod,outline a survey of the flexible rod machining,defines the working scheme of the rod.After work- ing,polishing and assembling,the flexible rod has a stable performance,satisfies design re- quirements.Originally,the working tool were grinded manually from a discarding centre drill,presently,ultrafine grain size carbide tool is used with microsize mechanical interlock, therefore,the boring work achieves good results,reduces working time and cost.
