Centerless Technology is a premier manufacturer of parts grinding in the Rochester, NY area. Because Centerless Technology also buys the bar stock needed by customers, they're often both the first and the last one to touch a part. Most manufacturers don't have in-house centerless or cylindrical grinding capabilities, which has helped make Centerless Technology a mission-critical partner to its 270 customers. We specialize in cylindrical grinding, thrufeed bar grinding, journal infeed grinding, bar straightening, burning & polishing, honing, and raw material supplier.
