First, CNC precision machining machine maintenance
1, half an hour before work every day to clean and maintain the machine If you use an air gun or oil gun to clean the chips, the spindle must have a knife.
2, prohibit the use of air guns or oil guns to blow the spindle taper hole, to avoid chips and other tiny particles of debris are blown into the main shaft hole, affecting the cleanliness of the spindle.
3、Check whether the lubricator is working normally, whether the lubricant is sufficient, and turn on the machine according to the normal order.
4, in the machine tool before the official work to start the spindle (speed of 501R / M) in order to carry out spindle warm-up.
Second, CNC precision machining machine operation
1, before the machine against the program list to confirm the processing blank type, size and machining allowance and the blank to sand and polish processing.
2, on the machine to confirm the placement of workpieces, as well as the processing process sequence, complete the more table action
3、Distribution, such as the need for "distraction bar" distraction speed of 501R/M, such as the use of knife distraction speed depends on the tool, in this process should also pay attention to the same height must be taken to ensure the accuracy of the distraction, the distraction is available after the end of the "G0 G54 X0 Y0" for inspection
4, formal processing before checking to confirm the placement of the workpiece and take the number of correct
Third. CNC precision machining precautions
1、Before processing each program, you need to strictly confirm whether the tool is consistent with the program
2、When loading the tool, you should confirm the length of the tool and the suitability of the chosen clamping head.
3、Keep the tool in the same workpiece in the same area every time to ensure the accuracy of the tool connection.
4、Use air blowing in the roughing program as much as possible, and spray oil in the light tool program
5、Before oil spraying in the light knife need to clean the machine tool aluminum slag to prevent aluminum slag oil absorption
6, in the cnc precision machining operation by itself, the operator shall not leave the machine tool or regularly check the machine tool running condition, if you need to leave midway, you must designate the relevant personnel to look at the check
7, in the process of processing, such as found that the machining allowance is too much, you must use the "single section" or "pause" to X, Y,
Z value zero after the manual milling off and then shake back to the "zero point "Let it run on its own
8, the processing process, such as found in the case of collision tool operator must immediately stop, such as pressing the "emergency stop" button or "reset button" button or the "feed rate" to zero, etc.
9, in the machine operation is prohibited to open the door to avoid flying knife or flying workpiece
10. The workpiece must be cleaned and deburred in time after the machine
11. At the end of the shift, the operator must do a timely and accurate handover to ensure that subsequent processing can be carried out normally
12. Before shutting down the machine, ensure that the tool magazine is in the original position, XYZ axis is stopped in the center position, and turn off the power supply and general power supply on the machine operation panel in turn.
13. When encountering heavy thunderstorms, the power must be cut off immediately to stop work
