Dennis Johnson, Jr., Grinding Specialists Inc.’s Plant Manager for Maintenance, said his company did its homework before buying the USACH 75. “Our primary purchasing criteria called for a production capable ID grinder that can hold 50 millionths tolerance,” said Johnson, Jr. The USACH 75 checked that box for Grinding Specialists.

If we run into any type of problem, in some cases someone from Hardinge can be here that same day. That kind of service doesn’t exist anymore.”


Among some of the features associated with the USACH 75 include the following :

  • Optimized ergonomics for easiness of set-up and maintenance for manual loading and unloading.
  • Low pressure air purge system and labyrinth seal incorporated to keep coolant contamination out of the spindle bearings.
