When starting the CNC machining Part, the operator should adjust the feed speed to a very low level, perform single block execution, and concentrate on rapid positioning, tool drop, and feed.

When starting the CNC machining Part, the operator should adjust the feed speed to a very low level, perform single block execution, and concentrate on rapid positioning, tool drop, and feed. The hand should be placed on the stop button and stop immediately if there is a problem, pay attention to investigate the tool movement Direction to ensure safe feed, and then slowly increase the feed speed to a suitable level, and add coolant or cold air to the tool and the workpiece.

Do not leave too far away from the control panel when roughing. If there is any abnormality, stop and check in time. After roughing, pull the meter again to confirm that the workpiece is not loose. If so, it is necessary to calibrate and count from the beginning. Continuously optimize processing parameters during processing to achieve better processing effects.

After the CNC machining Part is processed, it should be measured whether its main scale values are consistent with the drawing requirements. If there is any problem, immediately notify the shift leader or programmer to view and deal with it. After passing the self-inspection, it can be removed, and it is necessary to send it to the inspector. Check. Common types of CNC machining Part are as follows:

1. CNC machining Part hole processing: Before drilling the hole on the machining center, you must first use the center drill to locate, and then drill the hole with a drill that is 0.5~2mm smaller than the size of the drawing, and use a suitable drill for finishing.

2. CNC machining Part reaming processing: For reaming CNC machining Part, you must first use a center drill to locate, then use a drill with a size of 0.5~0.3mm smaller than the drawing size to drill, and then use a reamer to ream and ream processing. Always pay attention to control the spindle speed within 70~180rpm/min.

3. Boring processing: For boring CNC machining Part, first use a center drill to locate, then use a drill with a size of 1~2mm smaller than the drawing to drill the hole, and then use a rough boring tool (or milling cutter) to process until only the rest is left The machining allowance for one side is about 0.3mm, and then use a fine boring tool with a pre-adjusted size for fine boring, and then the one-time fine boring allowance cannot be less than 0.1mm.

4. Direct CNC operation: Before CNC machining, the CNC machining Part must be clamped, the zero position must be set, and the parameters must be set. Open the processing program to be transferred in the computer for viewing, then let the computer enter the CNC status, and enter the file name of the correct processing program. Press the TAPE key and the program start key on the processing machine tool, and the machine tool controller will now show a shining LSK word. Press the enter keyboard on the computer to perform CNC data transfer processing.
