Many CNC machining center friends do not know much about mechanical equipment, so in the work will encounter some problems, if you encounter CNC machining center spindle computer gongs do not turn, how to deal with it? In addition, the machine has not prompted any alarm information. What should you do at this time?
CNC machining center of computer gongs, in use, the spindle of CNC machining center of computer gongs does not rotate, which is a knife arm type tool magazine. When processing, the spindle does not rotate suddenly, and there is no alarm signal. And all the three axes can move normally. After giving a speed command in MDI mode, the spindle will not move a bit. At first, it was suspected that the shift signal was incorrect. After disassembling the z-axis gearbox, it was found that the shift of the spindle gear was normal and in place, and the in place signal was correct. But the spindle doesn’t rotate. In principle, if the spindle encoder or spindle is not powered on, it will cause an alarm. Therefore, the above two suspicions are eliminated, and the solutions to such problems are as follows:
Solution 1: first of all, you need to know whether you can see the parameters after 9000, and if you can, whether the parameters have been changed. I have encountered such a situation, is 0i-MC system, each axis is normal, that is, the spindle does not rotate. Later, the parameters after 9000 were changed.
Solution 2: there was an oi-m in the company before. It was found that the pneumatic valve of the knife arm was stuck. After the tool change, the knife arm should be ready for the next knife, but the knife arm was not put down, and there was no alarm. After the valve change, it was ready. And whether there is a hydraulic fixture, the fixture is not tightened, or the clamping signal is disconnected.
Solution 3: first take a look at the spindle monitoring, and turn the spindle manually to see if there are any values? Is the value right? The main shaft doesn’t rotate. There is no monitoring value, adjust the distance, or replace it with a new speed detection.
