以镗、铣削复合加工代替磨削加工的工艺改进方法

A Process Improvement Method for Replacing Grinding with Boring and Milling Composite Processing

磨削加工作为常规精加工的一种有效加工手段,能够很大幅度提升工件表面粗糙度和耐磨性,从而提升零部件加工精度,但是在磨削加工中有些零部件存在加工时间极长、加工工序冗杂等问题,这对于零部件在实际生产中会产生零件合格交付率低、生产效率缓慢的影响。因此,针对此类问题通过采用高硬度渗碳类产品零部件的加工刀具并且对刀具采用合理的涂层进行强化,能够实现以镗、铣削高速加工替代传统磨削的加工方法及刀具应用,克服磨削加工所带来的弊端,在保证产品质量的同时,提高了产品的加工精度及加工效率,消除了因磨削加工时所产生的高温变形等问题,提升了成品零部件尺寸的一致性问题。

Grinding,as an effective means of conventional precision machining,can greatly improve the surface roughness and wear resistance of workpieces,thereby improving the machining accuracy of parts.However,in grinding,some parts have problems such as extremely long processing time and complex processing procedures,which can have a low qualified delivery rate and slow production efficiency in actual production.Therefore,in response to such problems,by using machining tools for high hardness carburized product components and strengthening the tools with reasonable coatings,it is possible to replace traditional grinding methods and tool applications with high-speed boring and milling,overcome the drawbacks brought by grinding,and improve the processing accuracy and efficiency of the product while ensuring product quality,Eliminated problems such as high-temperature deformation caused by grinding,and improved the consistency of finished component dimensions.
