Our machine Mori Seiki MT253 has a problem with the life tooling direction on B axis when it is clamped at B=0 degree and B=-90 degree. I checked the life tooling spindle already, it is ok. So think the clamping mechanism of the B axis is the problem. Can you help me on how to fix this? It is also ok if you send me the drawings of the B axis with its clamping mechanism is also helpful too since I do not have the drawing and do not know where to start.
