TRU TECH Cylindrical Grinders

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.
