Hello,
I have a 94 Mazak SQT10MS. She is a grandma, but makes great parts when she is running.
As shown in the model number, this lathe has a rear spindle with live tooling.
Yesterday, the timing belt that drives the rear spindle back and forth on the gibbs (z) snapped..OUCH!
Of course it broke during a transfer.
Upon quickly looking under the back of the machine with a flash light, I thought it was going to be an easy belt swap out, but looking at it a little closer today, it appears it may be more of a challenge than I originally anticipated.
I still need to pull the coolant reservoir so it is out of the way and I have easier access.
I have already purchased a new timing belt which is a # 270L150.
The belt pulleys will be sitting right in front of me. The one toward the back side of the machine is completely open
and easy to slip the belt over. But, the pulley that is attached to the end of the ball screw has a 'cage' which allows the 'end coder' to be mounted outside of it at the end of the shaft.
I am wondering if any has changed this belt or one similar before. I am going to crawl under the machine shortly and was hoping someone has some insight about how to install the belt on the pulley/endcoder end?
I have not look close enough yet, but I do not see any bolts that hold the cage in place and thus the end coder in place.
The cage/end coder need to come off I believe. Is there a timing issue if I move or rotate the end-coder? Or, not because there are limit switches for travel?
Any hints or suggestions would be helpful.
Thanks much!
Mike
