The machine has a 20HP AC spindle, 30-station hydraulic tool changer, two-range hydraulically-shifted head, and chip conveyer system.
This is a Centroid M400 retrofit to a 50-taper machining center from around 1990. The retrofit was completed in November 2008.
The machine has a 20HP AC spindle, 30-station hydraulic tool changer,
two-range hydraulically-shifted head, and chip conveyer system.
This machine was originally equipped with a Yasnac MX3 control.
I installed a Centroid M400 with Yaskawa Sigma II servo drives and motors. I used a Koyo DL205 PLC unit, since the machine required more inputs and outputs than the Centroid PLCIO2 unit would provide.
The control cabinet is shown above. New Yaskawa servo drives are on the left;
the original Yaskawa 626-MTIII spindle drive is top center; power distribution
on the right; and the Koyo PLC is on the right-side door.
