Repair & Rebuild of a Mori Seiki MS-850 Lathe

At Dan’s Machine Tool, we can bring non-functioning equipment back to working order for a fraction of new equipment cost. This capability is highlighted with the Mori Seiki MS-850 lathe shown here which was repaired and rebuilt for a customer in the tooling industry.

When the lathe arrived at our facility it was in complete disrepair. We disassembled the primary components to assess the level of wear and provide the customer with a preliminary repair estimate.

The spindle, apron, tail stock, and head stock were all completely rebuilt. All spindle bearings were replaced and both x and y axes were aligned. The bed ways were removed, ground, and restored to parallel.

The aprons were then scraped to fit the newly repaired bed ways and the cross slides were scraped to fit the aprons. After the compound was scraped to fit the cross slide, all compound and cross slide hardware was replaced with new nuts and screws.

The tail stock was then scraped to align with the spindle and cross slide. Finally, the rack was built up to fit the carriage, resulting in a fully aligned, functioning lathe. In addition, a Newall AP-700 digital 2-axis readout was added for the customer.

The finished lathe was primed and painted gray for an attractive and protective finish.

We have extensive experience in the repair and rebuilding of a wide array of machining equipment including older mills and lathes. These machines were built with durable materials and high quality components and can often provide decades of service after refurbishment.
