以前我厂在加工孔平行面类型的零件时,大多采用两种方法:一种是采用划线方法加工,这样加工质量较差,并且生产效率较低。另一种是按照不同的零件,配备专用夹具,这样夹具的制造量就大。后来我们使用了孔平行面镗孔夹具,克服了前两种方法的缺点,很适用于多品种的小批生产。 In the past I plant processing holes parallel to the surface of the type of parts, most of the two methods used: one is the use of scribing method of processing, so processing quality is poor, and the production efficiency is low. The other is in accordance with the different parts, equipped with special fixture, so that the fixture manufacturing volume is large. Later, we used the hole parallel surface boring fixture, to overcome the shortcomings of the first two methods, it is suitable for small batch production of many varieties.
