在机床制造中,床身平面或棱形导轨的刮研,是繁重的手工劳动工序,因为机床床身的平面或导轨为配合表面,它不仅要求Ra0.8的表面粗糙度,而且还要求具有较高的直线度(一般为0.02/1000mm),故在刮研这些导轨表面时,其工作相当繁重,特别在中型和重型的机床制造工厂中更为显著。我们采用“精细刨削代刮研”,试验结果良 In the manufacture of machine tools, the scraping of the bed plane or the prism guide rail is a heavy manual labor procedure because the plane of the machine bed or the guide rail is a mating surface, which not only requires Ra0.8 surface roughness but also has Higher straightness (typically 0.02 / 1000mm) makes it extremely cumbersome to scratch the surfaces of these rails, especially in medium and heavy machine tool manufacturing plants. We use “fine shaving instead scratch research”, the test results are good
