Correct operation and use of CNC machine tools

The correct operation and use of CNC machine tools:

I. Overview: The maintenance concept of CNC machine tools can not be simply confined to the failure of the CNC system, how to eliminate the fault and timely repair, so that the CNC system put into use as soon as possible, but also include the correct use and daily maintenance.

Second, the correct operation and use of the CNC system steps:

1. Check before power on CNC system:

1) Check if the printed circuit boards in the CNC device are tight and if there is looseness in each plug.

2) Carefully check that all connection cables between the CNC unit and the outside world are correctly and reliably connected according to the specifications of the supplied connection manual.

3) Whether the AC input power supply connection meets the requirements of the CNC device.

4) Confirm whether the various hardware settings in the CNC device comply with the requirements of the CNC device. Only after the above check, the CNC device can be put into power operation.

2. Inspection after power-on of the CNC system 1) First check whether each fan in the CNC device is operating normally.

2) Check whether the DC power supply on each printed circuit or module is normal and within the allowable fluctuation range.

3) Further confirm various parameters of the CNC device.

4) When the numerical control device and the machine tool are energized on-line, the inlet pump shall be used to press the emergency stop button at the same time when the power is turned on, so as to cut off the power at any time in the event of an emergency.

5) Manually move each axis at a low speed to observe whether the display of the machine direction is correct.

6) Perform several operations returning to the machine reference point to check whether the CNC machine has returned to the reference point function and whether the position of each return to the reference point is exactly the same.

7) Functional test of the CNC device.
