一、前言 罗茨轮(图1)是应用极广的罗茨流量计中关键的计量元件,其型面构成复杂。目前常用的加工方法是铣削和刨削,生产效率低,表面粗糙,波纹大,形状精度也不易控制。为此,我们在原有的由车床改装的罗茨轮仿形铣床上进行了砂带磨削试验,取得了满意的效果。本文介绍了用砂带磨削 I. INTRODUCTION The Roots Wheel (Figure 1) is a key metering element in an extremely wide range of Roots flow meters, with complex profiles. The commonly used processing methods are milling and planing, low production efficiency, surface roughness, large ripples, shape accuracy is not easy to control. For this reason, we carried out the belt grinding test on the original Roots round profile milling machine modified by a lathe, and achieved satisfactory results. This article describes the use of abrasive belt grinding
