I have a really strange vibration problem with my Bulgarian ZMM lathe. It's a great machine which I've used for over 18 years, however it has slowly developed a vibration in one gear. This is where it gets weird: If I reverse the motor (3 phase) and put the machine in reverse (so the spindle still rotates correctly) the machine is as smooth as silk! Really can't get my head around this, obviously I need to have a look in the headstock but finding time in my busy shop is a problem.
Any ideas?
