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.
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.
The T93XM-A system adds reliable part automation to this highly precise grinder to maximize the productivity and efficiency of your high-value part profile grinding operations.
