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.

Precision OD Grinder

The TRU TECH TT1020M delivers exceptional accuracy, flexibility, and operator-friendly simplicity for producing a wide range of precision tooling. Icon-based Conversational Software™ allows operators to program shapes and profiles in minutes, while built-in training and maintenance modules streamline operation, reduce downtime, and help lower total cost of ownership.

Capabilities Include:

Profile grind and plunge grind

Grind diameter: up to 229mm (9”)

Grind length between centers: up to 508mm (20”)

Max. load held between centers: 80kg (176 lbs)
