Welcome to The Machine Tool Rebuilders Group

"Quality and accuracy is our first consideration, and must never be sacrificed in the interest of a low selling price, but a fair price."

This was the business philosophy of Rudy Bannow and his partner Magnus Wahlstrom, the Bridgeport Machine Company founders. It is the simplicity and practice of this philosophy that has carried the Bridgeport mill into the 21st century.

The Machine Tool Rebuilders Group, has been practicing and following this philosophy for the last 37 years. Following this simple business philosophy has helped the Machine Tool Rebuilders Group become one of the premier machine rebuilders in the United States.

While Bridgeport became an American Icon, other machine tools emerged and became leaders in their respective categories; Bridgeport vertical mills, TRAK CNC bed mills, Mitsui surface grinders, Harig surface grinders, and Hardinge lathes. We concentrate our efforts on the premier machine tools, because quality breeds quality and these machines were made to be rebuilt.




"We are a machine rebuilder of used Bridgeport mills, Hardinge lathes, Harig surface grinders, Okamoto surface grinders, Mitsui surface grinders, and TRAK bed mills first and foremost, because that is our specialty."

- Tim Kelly, VP of Operations.

Customer Testimonials:

“Thank you for the quality of the work you did on our Bridgeport mill. It looks very nice and everything works wonderfully, it’s been sometime since we have had a mill in this good of repair. You have won our future business and we are hoping to send at least one more machine this summer, I am working on two but our budget might not allow it.”

"Thanks for such a detailed reply... Seems that true enthusiasm for a job well done lacks these days. Glad to see some people still believe in craftsmanship! Will be keeping your info and when I am ready to buy a mill I will be in touch."
