过去这种缸体的止推面和油封槽用铣刀从两端加工,并须在此工序前后由人工拆装轴承盖,效率低且精度不易达到。本文介绍的镗孔车端面机床用于加工前后止推面及油封槽,除手工装卸工件外,全部实现自动控制,且保证了加工精度要求。图4幅,表3个。 In the past, the thrust surfaces and oil seal grooves of this cylinder were machined from both ends by a milling cutter and the bearing cap was manually disassembled before and after this process, which was inefficient and difficult to achieve. This article describes the boring machine end face machine for processing before and after the thrust surface and the seal groove, in addition to manual loading and unloading of workpieces, all of the automatic control, and to ensure the processing accuracy requirements.
