发动机曲轴制造技术新动向

The New Development of Engine Crankshaft Manufacturing Technology

进入21世纪以后，发动机曲轴在制造工艺、刀具等方面都发生了巨大的变化，与以前加工工艺有很多不同。领导了近半个多世纪的多刀车削工艺和手工磨削工艺，由于加工精度低和柔性差等原因，将逐步退出历史舞台。而高速、高效、复合加工技术及装备迅速进入汽车及零部件制造业，曲轴的高速高效复合加工技术在行业内已有相当程度的应用，也必将代表这一行业的未来发展趋势。

After the No.21 century, the enormous change of engine crankshaft on manufacturing technology, cutting-tool etc, it has differ from old manufacturing technology. The multiple cutting-tool turning technology and hand grinding technology of leading half-century will be exited history, arena, because of low machining accuracy and flexible. And that, the high-speed,high-efficiency ,complex machining technology and equipment have entered automobile and parts industry. This technology has been used to automobile and industry, and it will delegate development current.
