摘要

摘要: 本文使用4种不同粒度型号的金刚石砂轮分别对硬质合金YG8进行了有、无旋转超声的端面磨削实验,并利用超景深显微镜和白光干涉仪观测了这两种加工方式下的工件表面质量。实验结果表明:当采用粒度号较小的金刚石砂轮时,有旋转超声的工件表面粗糙度要比无超声时的差;但对于粒度号较大的砂轮,有、无旋转超声所得到的工件表面粗糙度差异并不明显,甚至有旋转超声时的表面质量会略优于无旋转超声时的检测结果。相比于传统加工方式,旋转超声的使用可以明显减小被加工材料表面出现裂纹的几率。

Abstract: In this paper,four kinds of diamond tools were used for the grinding experiments on cemented carbide YG8,with and without ultrasonic vibration.By using the white light interferometer and the microscope which has an ultra-deep observation field,surface qualities of the work-piece can be easily detected.The experimental results show that the diamond tools with big grain size,the surface roughness of the work-pieces machined with rotary ultrasonic vibration are worse than that without rotary ultrasonic vibration;while the roughness differences between the work-pieces machined with and without rotary ultrasonic vibration are not obvious at the small grain size.Furthermore,comparing with conventional diamond machining,it will be easier for rotary ultrasonic grinding to prevent the growth of cracks.
