The CNC machining process of fasteners is a part, or even a process, of the overall machining process of the workpiece. Only with other before and after the process, to meet the requirements of the whole machine or mold installation, and then processing a qualified parts. CNC centering machine processing factory that the CNC machining process is generally divided into roughing, medium rough chamfering, semi-finishing and finishing. For rough machining, try to use a larger tool, in the machine power or tool can bear the scope of a larger cutting volume, as early as possible to disconnect a large amount of workpiece material. In order to avoid rough machining due to cutting vibration caused by the workpiece loose, rough machining should be timely check the meter, if necessary, the tool should be adjusted again. After rough machining, you are able to finish the datum point with the exhausted tool to prepare for the future calibration. For workpieces with complex cavities, a large amount of capacity will remain in the corners due to the large tools used for roughing, so secondary roughing or chamfering must be done with tools smaller than roughing. To reduce tool wear, semi-finishing can be carried out when the machining area is relatively large. To avoid excessive cutting, sufficient capacity must be left for finishing at each step. In general, try to check on the machine, pass and remove, and then prepare for the next processing step.
