1K36大六角车床的旋转头轴承与定位游隙量以及主轴中心线与旋转头工具孔中心线不同心度的精度修复,是很困难的。最近我厂在修理实践中攻破了这个关键,现介绍于下。一、旋转头与溜板互相结合面的刮研它的刮研方法参看图1。(1)刮研溜板旋转面:直接利用滚柱2与平板6做检验工具进行刮研并用百分表控制,其允差0.015 1K36 large hexagonal lathe rotary head bearing and positioning clearance as well as the centerline of the spindle and the center line of the rotary tool hole not concentric accuracy of repair is very difficult. Recently, I plant in the repair practice to break this key, are introduced below. First, the rotating head and slide the surface of each other scraping the scraping research method shown in Figure 1. (1) Scraping slide plate rotating surface: direct use of roller 2 and plate 6 as a test tool scraping and control with a dial indicator, the tolerance 0.015
