Division of filter press process

To ensure the processing quality of the plate and frame filter. In rough machining, because a large number of metal is to be cut off, there will be a large cutting force and cutting heat, but also a large clamping force. Under the action of these forces and heat, the parts will have a large deformation. Moreover, after rough machining, the internal stress of the parts should be redistributed, which will also make the parts deformed. If we do not divide the processing stages and continue to process, we can not avoid and correct the processing errors caused by the above reasons. After dividing the machining stage, the errors caused by rough machining can be corrected by semi finish machining and finish machining, and the machining accuracy and surface quality of parts can be improved gradually to ensure the machining requirements of parts.
