【摘要】 在铣削汽车发动机和变速器的几个大平面时，由于受机床主轴的回转精度以及夹具精度的影响，加工中易出现啃刀、刮伤等现象。为避免发生啃刀、刮伤等现象，提出应将机床主轴调整一个角度。并建立了调整角度的经验公式。更多还原

【Abstract】 When large plane surfaces of engine and transmission components are machined by means of milling machine,phenomena of tool abrasion and scratching often occurred owing to the effect of limitation of fixture accuracy and turning accuracy of machine main spindle to avoid the phenomena of tool abrasion and scratching and sets up an empirical expression of the adjustment.更多还原
