Micromill Spindle Problem
Posted: Wed 13 Sep , 2023 11:35 am
Hi.
So lately I've restored our Uni's micromill after it's not being used for about 5 years (since 2014 I think). No problem at the stepper motor, or 3 axis movement. Connection to user PC is also a success.
But I encountered a problem when trying to start the spindle. both with the spindle forward button in the VR Milling software (ver. 5 btw), or using the NC code, the spindle only started spinning for about half a second, but stopped and the machine light intensity was also weakened for a bit. The symptoms looks like there's not enough power to turn the spindle, or there is a safety mechanism preventing the spindle to continue spinning. the indicator in the software showing there's no problem with it (green indicator as if the spindle were spinning). Also when i try to rotate the spindle manually, there is nothing jamming it or anything. It rotates just okay.
My question is Are there safety mechanisms or relays that potentially cause this problem? My suspicion is that the electronic shear key (honestly I'm not sure what this is) reads something wrong and prevent the spindle to spin.
Thank you very much.
