Northland Tool & Electronics rebuilt this entire assembly for our customer. We were able to solve part finish issues they were having in their production runs. Careful attention was payed to the shaft run outs and the collet clamping system. We also worked with our customer on installation and removal techniques that will help the spindle to run accurately.
Upon inspection of this Miyano workhead spindle, we noted that it suffered bearing failure from contamination in the front and rear. No dimensional deviations were noted for the repair.
The following actions were performed on this Okuma MC-V4020 spindle:
- Clean, inspect overall dimensions.
