一、概述随着我国录象机行业的发展,高精度数控磁鼓车床将成为不可缺少的关键设备,为此,上海机床厂研制了ST211,ST212高精度数控上、下磁鼓车床各一台。本文将着重介绍ST211上磁鼓车床的结构特点。磁鼓是录象中的关键零件,技术要求高,其圆度,同轴度、垂直度及尺寸分散度都在微米级。图1是松下9200型录象机的上磁鼓零件图,。要高效且成批地加工这样的零件,其加工设备应满足如下要求:
I. Overview With the development of China’s video recorder industry, high-precision CNC drum machine will become an indispensable key equipment, to this end, Shanghai Machine Tool Plant developed ST211, ST212 high-precision CNC upper and lower drum lathe each one . This article will highlight the structural features of the ST211 turret lathe. The drum is the key part of the video, high technical requirements, its roundness, concentricity, verticality and size dispersion in the micron level. Figure 1 is Panasonic 9200 VCR parts on the drum. To process such parts efficiently and in bulk, the processing equipment should meet the following requirements:
