2022-09-05

1. Hole processing: before drilling on the machining center, the center drill must be used for positioning, and then the drill bit 0.5~2mm smaller than the drawing size shall be used for drilling, and the appropriate drill bit shall be used for finishing. 2. Reaming: For reaming the workpiece, first use the central drill to locate it, then use...

Why should CNC machining leave machining allowance on the workpiece

2022-09-05

The thickness of the metal layer cut off in each process of CNC machining is called inter process machining allowance. For the torsioned outer surfaces such as the outer circle and hole, the machining allowance is considered from the diameter, so it is called symmetrical allowance (i.e. bilateral allowance), that is, the thickness of the metal laye...

Advantages and disadvantages of cnc machining different guideways

2022-09-05

1. There is an oil chamber between the two guide rail working surfaces of the hydrostatic guide rail. After a certain pressure of lubricating oil is introduced, a hydrostatic oil film can be formed, so that the guide rail working surface is in pure liquid conflict, without wear, and has good accuracy retention; At the same time, the conflict coeffi...
