Hi All,
We have an old Rye machine which recently developed a strange Y axis error.
It sometimes trips out during machining or even when the spindle is stationary.
There may be a strange 'whistle' or a quick grinding noise before it stops.
The ball-screw was serviced and bearings replaced.
We tried swapping optical tacho, cleaning brushes, swapping drive cards (Bosch CC120) and even swapping the entire motor. The same problem still exists only on the Y axis.
Any ideas or anyone know a good service engineer for old Rye machines here in the UK.
Thanks, Rob.
