缸体镗孔车止推面精密数控组合机床研制

摘要

This article states the method for processing cylinder block crankshaft bores, thrust faces, cam-shaft bores and end face dowel holes by a precision CNC machine tool, it also gives detailed presentation on the machine layout and its key components. The development of this machine has solved the critic technical issues for the domestic engine industry who have relied on imported equipment for a long time to guarantee the machining accuracy of cylinder block crankshaft bores, thrust faces and camshaft bores. The machine is working well with stable and reliable accuracy. It can completely replace imported machine.%文章介绍了用精密数控机床加工缸体主轴承孔及止推面、凸轮轴孔、端面销孔的方法，并对机床的布局及采用的关键部件做了详细的阐述。该机床的研制，解决了国内发动机行业长期依赖进口机床来保证缸体主轴承孔及止推面和凸轮轴孔的加工精度的关键技术问题。目前该设备运转良好，加工精度稳定、可靠，已经完全替代进口。
