Your Leader in Bridgeport, Okamoto, Harig Surface Grinders, Mitsui, and  Hardinge Machine Rebuilding and Refurbishing

Over the years, manual machining equipment has taken a back seat to more advanced forms of CNC machining in order to keep up with the fast paced, high demand production environments of today. While manual machining processes may seem to be a thing of the past, most manufacturing facilities still utilize this equipment on a daily basis. Some still see them as the backbone of their business, supporting their day-to-day manufacturing efforts. So why is it that these machines don’t seem to garner the same attention as that of their more advanced counterparts?

The team here at USA Machine Builders understands that these machines were designed with quality in-mind and were certainly built to last. This is why for nearly 40 years now our team of experts has been rebuilding and refurbishing these forgotten gems and providing them with some well-deserved attention.

Furthermore, now that we have joined with the All World family, we have the ability to expand these efforts and provide our services to a much wider and farther-reaching range of customers.

This includes expanded capabilities for control retrofits, in-house component repair services, and a vast inventory of replacement components ready and available for immediate shipment.

Machines will be rebuilt to like-new condition and will be returned to OEM standard of alignment and performance. We will completely disassemble your machine, and all components will be thoroughly inspected and evaluated.

So if you are looking to rebuild your Bridgeport, Okamoto, Harig Surface Grinders, Mitsui, or Hardinge machine, USA Machiner Rebuilders is your number one stop!
