Handling method of handwheel failure during CNC machining
by：QY Precision 2020-04-14
Cnc machining, as a machine tool and equipment widely used by major industries and enterprise manufacturers for a long time, will inevitably lead to unexpected or man-made failures in the process of processing products, especially the problem of handwheel failure in the processing center, today we have summarized this problem as follows and given some corresponding solutions, hoping to help everyone. First, the processing center has a handwheel failure. To analyze the cause of the failure, we can start with the following four points: 1. Please check whether the handwheel shaft selection switch has poor contact; 2. Handwheel magnification please select'Poor switch contact'; 3. Please check whether the handwheel pulse is damaged; 4. Please check if the handwheel connecting wire is broken. Second, we can solve the problem of handwheel failure in the machining center from the following four points: 1. Enter the system and diagnose and observe the contact situation corresponding to the shaft selection switch (Here refers to the integrity of the cable) If you find damage, you can replace the switch. 2. Enter the system and diagnose and observe the contact situation corresponding to the magnification switch (Here refers to the integrity of the cable)If the switch is damaged, it can be solved. 3. Take off the pulse disc and measure the power supply to see if the power supply is normal. If the resistance between + and A, + and B is normal, if it is found to be damaged, please replace the power supply. 4. enter the system, conduct diagnostic observation, check the corresponding contacts of each switch, and then measure the axis selection switch, the magnification switch, and check the contacts of the connecting wires between the pulse discs, whether the point corresponding to the incoming system terminal is on or off, if the check is broken, replace it in time. The above is the problem of the CNC machining center handwheel fault and the treatment method. If your machine tool has such a problem, you can check and diagnose it in turn. According to the treatment method, I believe it can solve the problem.
