Locher, Inc. carried out a complete spindle repair and rebuild for a client in the machining industry, making use of our versatile and broad repair, machining, and assembly capabilities. We received the spindle in very poor condition from our customer, who required a finished "like-new" condition. The main problem with the spindle was a series of cracks around the keyway, which were milled out and welded. The entire shaft was then reground true and concentric.
We also worked with a customer to modify and develop a solution to an issue with the spindle cartridge oiling lubrication system. Bearings for this particular cartridge, matching the dimensions and system, were extremely expensive and difficult to find. We decided to plug the oiling ports and install greased bearings for identical operation at a lower cost. In addition to the cartridge rebuild, a full drawbar rebuild was also part of this project. Maintaining a tolerance of ± .0001", the finished, like-new spindle was delivered to the customer within 3 weeks.
