This is a 45,000 rpm ID grinding spindle. The customer sent it in claiming that the spindle was running hot and the amp draw was high. We tested the field upon incoming and it passed all critical testing. The spindle bearings were rough. We spoke with the customer and discovered that they had thought the spindle was a 60,000 rpm spindle. The spindle needed to have the bearings changed and we needed to make sure this spindle was put into the correct machine. We replaced all tags on the spindle and are making sure the customer is aware of the model number.

Okuma MX50 HA Spindle Repair
One of our customers was experiencing chatter on the parts manufactured in their Okuma MX50 HA. They could not afford downtime but the parts were becoming unacceptable. They pulled the spindle on Thursday afternoon and we received it late in the day. We evaluated the cause of failure and what work needed to be done to fully repair the spindle. We dedicated a technician to the repair and we were able to have the spindle repair completed by early Friday afternoon. The Okuma technician was able to install the spindle Friday before the end of the workday.
The repair was done in less than 24 hours and the machine was making parts in a little over 24 hours.
