利用工件自导向精镗大型柴油机气缸体曲轴孔、凸轮孔工艺

The Technics of Final Boring Crankshaft and Camshaft in the Cylinder Block of Huge Diesel Engine by Using Workpiece Self-Guiding

介绍了一种利用大型镗杆解决大型柴油机气缸体主轴孔精加工的应急加工工艺,这种镗杆采用新型材料替代常用材料设计和制造,充分利用通用卧式加工中心、卧式镗床等设备进行加工,实现低成本、快速生产目标;满足大型发动机试制样机快速开发、适应瞬息万变的市场需求。

A kind of urgent machining technics, Making big size boring-bar machine final crankshaft hole of cylinder block in huge diesel engine is introduced. The boring-bar is made of new material instead of normal material. Making good use of Mchining Center Horizon and horizon boring tool etc. which could realize the target of low cost and rapid preduction. The machining technics could satisfy quick exploitation and trial-preduction of huge sample machine ,and the requirement of rapid changing market.
