Precision machining is a very rigorous process. What problems should we pay attention to before and after processing and processing?
First, CNC precision machining machine maintenance
1. Clean and maintain the machine tool half an hour before work every day. If you use an air gun or oil gun to clean the chips, you must have a knife on the spindle.
2. It is forbidden to blow the spindle taper hole with the air gun or oil gun to prevent the tiny particles and other debris from being blown into the spindle hole, affecting the cleanliness of the spindle.
3. Check whether the lubrication machine is working properly and whether the lubricant is sufficient and start the machine in the normal order.
4. Spindle start (rotation speed is 501R/M) to perform spindle warm-up before the machine tool works.
Second, CNC precision machining machine operation
1. Check the model number, size, and machining allowance of the processed blanks before the machine and check the blanks.
2, after the machine to confirm the placement of the workpiece, and the order of processing technology to complete the action than the table
3, if you need to divide the middle, the speed is 501R/M. If you use the knife, the speed will depend on the tool. In this process, you must also pay attention to the same height to ensure that The accuracy of the score can be verified by "G0 G54 X0 Y0" after the middle
4, before the formal processing and then check to confirm the placement of the workpiece and take the number is correct
Three, CNC precision processing precautions
1. Before processing each program, it is necessary to strictly confirm whether the tool is consistent with the program.
2, when loading the knife to confirm the length of the tool and the selected knife head is appropriate
3, in the same workpiece each time the knife must be kept in the same area to ensure the accuracy of the tool when the knife
4, try to use the air blowing in the open program, in the light knife program is injected
5. Clean the aluminum slag inside the machine before the light knife to spray oil to prevent the aluminum slag from absorbing oil.
6. During the operation of cnc precision machining, the operator must not leave the machine tool or check the running status of the machine regularly. If you need to leave in the middle, you must specify the relevant personnel to check it.
7. If excessive machining allowances are found in the machining process, you must use “single-stage” or “pause” to clear the X, Y, Z values manually, then mill them out and then roll them back to “zero” to make them run
8. If the impactor is found during the machining process, the operator must stop immediately. For example, press the "emergency stop" button or "reset button" or adjust the "feed rate" to zero, etc.
9, prohibit the boot door in the operation of the machine to avoid flying knife or flying parts
10. The workpiece must be cleaned and deburred in time after leaving the machine
11. At the time of off duty, the operator must do a timely and accurate handover to ensure that the subsequent processing can be performed normally.
12. Ensure that the tool magazine is in the original position before shutting down, and the XYZ axis stops at the center position. Turn off the power and main power on the machine's operation panel in turn.
13.The power must be cut off immediately when it comes to heavy thunderstorms
