1. Finishing of bed castings is a process that removes a small machining allowance from the roughed surface so that the workpiece can achieve higher machining accuracy and surface quality. It is a finishing process. CNC lathe finishing is often used as final processing.
2. Finishing of bed castings is to remove a small machining allowance from the surface of the finished workpiece to obtain high machining accuracy and a small surface roughness value. Methods such as grinding, honing, super-finishing and polishing are finishing processes.
3. Rough machining process of bed castings. The CNC lathe cuts off most of the machining allowance from the workpiece to make its shape and size close to the requirements of the finished product. This is the rough machining process. Its processing accuracy is low and the surface roughness value is large. It is generally used for the final processing of undemanding or non-fitting surfaces, and is also used as a pre-processing for finishing.
