高精度钻模一般都需要在精密的坐标镗床上加工。在没有精密坐标镗床的情况下,我们设计了组合式高精度钻模(见图),在普通机床上也可以加工。该钻模的8个孔在直径为D的圆周上均匀分布。孔
High-precision drilling generally require precision boring machine in the coordinate processing. In the absence of a precision boring machine, we have designed a combined precision drill (see photo) that can be machined on a common machine. The eight holes in the die are evenly distributed over a circumference of diameter D. hole
