CNC lathe machining process division principles

Maintain the principle of precision. CNC lathe machining requires that the process be as concentrated as possible. Usually rough and finish machining are completed in one clamping. In order to reduce the impact of thermal deformation and cutting force deformation on the shape, position accuracy, dimensional accuracy and surface roughness of the workpiece, rough and finish machining should be Finishing is carried out in stages for shaft or disk parts. All surfaces to be processed are roughed first, leaving a small margin for finishing to ensure processing quality requirements. For workpieces with holes and threads on the shaft, the outer surface should be machined first and then the holes and threads should be machined.

The principle of improving production efficiency. In CNC lathe machining, in order to reduce the number of tool changes and save tool changing time, all the processing parts that need to be processed with the same tool should be completed, and then another tool should be used to process other parts. When using the same tool to process multiple parts of the workpiece, the shortest route should be used to reach each processing part to minimize the idle travel time.

In actual production, the division of CNC lathe machining processes must be comprehensively considered based on the structural characteristics and technical requirements of specific parts.
