CNC machining type:
Hole processing: Before drilling on the machining center, be sure to use the center drill to locate, then drill with a drill bit 0.5~2mm smaller than the drawing size, and finally finish with a suitable drill bit.
Reaming processing: Reaming processing of the workpiece also needs to be positioned with a center drill, then drill with a drill bit 0.5~0.3mm smaller than the drawing size, and finally reaming with a reamer. Pay attention to control the spindle speed when reaming. Within 70~180rpm/min.
Boring processing: To perform boring processing on the workpiece, first use a center drill to position, then drill with a drill bit 1~2mm smaller than the size of the drawing, and then use a rough boring cutter (or milling cutter) to process only 0.3mm on one side The left and right machining allowances are finally used for fine boring with a fine boring tool of pre-adjusted size. The final fine boring allowance should not be less than 0.1mm.
Direct CNC (DNC) operation: Before DNC CNC machining, the workpiece must be clamped, the zero position set, and the parameters set. Open the processing program to be transferred in the computer to check, and then let the computer enter the DNC state, and enter the file name of the correct processing program. Press the TAPE key and the program start key on the processing machine. At this time, the machine tool controller will flash LSK. Press the Enter key on the computer to process the DNC data.
