CNC lathe processing handwheel failure is mainly manifested in the following four aspects

CNC lathe processing handwheel failure. CNC machining handwheel failure is mainly manifested in the following four aspects:

The handwheel axis selection switch is in poor contact. This problem needs to enter the system self-check to investigate the axis selection switch matching contact details (continuous line is intact and detailed environment), if damaged, replace the switch.

The handwheel selection switch has poor contact.. The correct step to deal with the poor contact of the CNC machining handwheel multiple selection switch is to enter the system self-check to check the matching contact details of the multiple switches (continuous line intact details) ), if damaged, the switch can be replaced.

About the damage of the handwheel pulse generator disc, it is necessary to remove the pulse disc and measure the switching power supply to see if it is all normal, and the resistance between A and B is not normal. If it is damaged, replace it.

CNC machining handwheel continuous line breaks the staff enters the system self-inspection to investigate the detailed environment of the matching contacts of each switch, and measure the contact and response between the axis switches, multiple switches, and pulse disc continuous lines Click to enter the on-off of the system terminal, such as off-replacing.

Wuxi CNC lathe factory cannot return to the zero point in the middle. In response to this problem, it is important to have the following comprehensive summary:

When the contact of the CNC origin switch is stuck, a professional clearing card is required. Hold the position and make it move stably, or replace the distance switch.

The origin block of CNC lathe processing cannot be pressed to the switch action position. Adjust the installation position of the distance switch, so that the zero switch contact can be stably pressed to the switch action position by the stopper.

The inlet of the origin switch causes poor contact. Replace the distance switch and take waterproof measures.

The line of the origin switch in the middle of CNC lathe processing is disconnected or the input light source is faulty. Check the switch to see if there is an open circuit, a short circuit, and the light source.

There is a problem with the CNC machining tool magazine.

1, during the tool change process, the CNC stops suddenly and cannot continue to change the tool. If the pressure does not reach the ideal pressure, the tool change will fail.

2, the hat-type tool magazine can't come out.. Check whether the data light signal is in place after the cnc disposes the object library, the object library enters and exits the solenoid valve line and the PLC has no output..

3. The tool cannot be released during the tool change process of CNC machining. Adjust the tool volume of the lathe, and check that the tool cylinder block does not accumulate water. If there is water, take timely action.

4, the CNC lathe machining tool head suddenly reverses the time difference by half the tool position. This is because the brake mechanism of the tool magazine motor is loose and cannot be braked normally.

5. When changing the tool, the error alarm of loosening and tightening occurs. Check whether there is air pressure in the middle of CNC machining, whether the cylinder has sufficient action (if there is water), and whether the release switch is not pressed in place, and cannot be pressed too much.
