Our versatile TRU TECH universal cylindrical grinders allow for multiple diameters, complex shapes, and angles to be ground. These systems use a headstock comprised of a chuck, or a center with a driver, to hold and rotate the workpiece. This ensures that all diameters ground about the central axis of rotation are concentric with each other and with any other internal diameters that are concentric or “true” with the centers. These machines are ideal for finishing the outside diameter of small cylindrical metal parts requiring a tight tolerance.
Designed for the bigger jobs, the T23XM is larger, longer, bigger and faster. This machine features an 8” diameter swing and 20” length between centers. Featuring a fully controlled variable speed 10HP spindle motor, it can accommodate up to a 16” diameter x 2” wide grinding wheel.
