Koehler Ball Grinding Machine Services

Deasey Machine has been designing and manufacturing parts for the ball bearing industry since the early 1980's. Prior to founding Deasey Machine Tool & Die, Paul Deasey worked as a machinist, building Koehler ball grinding machines for Koehler and Sons in Philadelphia for more than two decades, beginning in 1955. Upon their closing, Mr. Deasey started his own business providing machine shop services. As the business continued to grow, he saw the opportunity for supplying parts and services to the ball bearing industry for the Koehler Ball Machine. 

Deasey Machine has continued to expand it's services to include manufacturing parts for other makes of ball bearing machinery and ball processing equipment. What started out as a small family business, Deasey Machine has now grown to serve customers nationwide and internationally. Our experience and dedication to quality and customer satisfaction is second to none in this industry.
