激冷铸铁在机械制造中用来制作表面硬度高而且耐磨的零件,如柴油机配气挺杆、轧辊等。过去认为激冷铸铁是不能进行切削加工的,只能采用磨削加工的方法,生产效率很低。现在采用陶瓷刀具车削,为激冷铸铁的切削加工开辟了新的途径。下面以我厂生产的柴油机配气挺杆为例,谈谈激冷铸铁的车削加工。 Chilled cast iron used in machinery manufacturing to make high surface hardness and wear-resistant parts, such as diesel engine with gas tappet, roll and so on. In the past that chilled cast iron can not be machined, only grinding method, the production efficiency is very low. The use of ceramic tool turning now opens up new avenues for the machining of chilled cast iron. The following diesel generator with I plant gas tappet, for example, to talk about chilled cast iron turning.
