Nc punch machine benchmark selection principle
1. Choice of nc punch benchmark coarse benchmark Nc punch machine (1) the choice of rough base: to ensure that the main processing by enough and uniform processing allowance, which is conducive to ensure the main surface and processing accuracy and physical and mechanical properties of the surface layer. (2) if the workpiece does not need to be processed surface, you should choose the towel and machining surface have mutual position precision crack table because of coarse benchmark.
