TRU TECH Centerless Grinders

The TRU TECH line of centerless grinders provides precision surface grinding on cylindrical workpieces without the need for centers or chucks. Key to the TRU TECH grinders repeatability and consistency of closely held tolerances is the Perimetric 3-point work holding capability, enabled by the patented TT5000 and PP8000 Perimetric™ Grinding Units. The TRU TECH 3-axis centerless grinders can handle a wide range of workpiece diameters and processes, including plunge, centerless, ID, OD, infeed and form grinding.

TRU-TECH-T93XM-grinding-machine-closed-door

Fully enclosed, while improving sight-lines and ergonomics. 50LPM coolant flow capability ensures minimal wheel build-up and optimal size and finishes with autoload feature

Newly designed pendant reduces machine footprint and allows you to work closer to the work piece during setup. The controller can store multiple part programs that can be called up through the system access panel. Industrial grade computer with Intel processor for fast, reliable editing and storage of programs.

Computer controlled variable-speed spindle

Multiple wheel dressing capabilities for diamond and borazon wheels. Parts can be loaded and removed without the need for an indicating. Parts are perfectly aligned and ready for processing.

Key to these grinders is the patented Perimetric™ Grinding Unit. A part being ground can be removed from the regulating roller, inspected, and then returned to the regulating roller by hand without any indicating. Part repeatability and concentricity is within millionths.

High Precision Centerless Profile Grinder

Designed with ultra-precision form grinding in mind, the T93XM features Perimetric 3-point work holding capability offering sub-micron accuracy and incredibly fast, set-up friendly control along with the latest in material technology. The 7,000 lb. T93XM is one of the most stable and rigid precision grinding machines on the market today.
