加工曲轴曲柄椭圆,通常是在专用铣床上,用周边铣削方法进行。专用铣床的铣刀盘直径为1.5米至2米,对毛坯的要求是加工余量均匀,且在10毫米左右。我厂提供的全纤维锻造曲轴毛坯的加工余量为50毫米,采用周边铣削工艺,是有困难的。通过实践,试验了用端铣作粗铣和宽刃铣作精铣的加工工艺,满足了生产要求。其加工原理,基本上与彷形车削相同,不同点在于将刀架换成铣头,介绍如下。 Crankshaft processing oval, usually in a special milling machine, with the surrounding milling method. Milling cutter milling disc diameter of 1.5 meters to 2 meters, the requirements of the rough machining allowance even, and about 10 mm. I plant the entire fiber forging crankshaft rough machining allowance of 50 mm, the use of peripheral milling process is difficult. Through practice, we have tested the processing technology of rough milling with end milling and wide milling with milling to meet the production requirements. The processing principle, basically the same with the profile turning, the difference lies in the tool holder replaced milling head, introduced as follows.
