Star Cutter will be demonstrating the capabilities of the TRU TECH T93XM Perimetric grinder through shadow grinding in booth #237013 at IMTS 2024. These centerless grinders provide sub-micron accuracy via a high speed, user-friendly control plus the stability and rigidity needed for precision grinding. They are available with and without autoloading.
The T93XM, as it is referred to, can profile with a standard 1A1 wheel and accommodates several grind styles including wheel profile, plunge, peel, in-feed and thru-feed grinding. The perimetric workholding, unique to TRU TECH, ensures part concentricity to eliminate shank runout without indicating. Ultra-precision accuracy is achieved through the 3-axis, fully programmable configuration with CNC variable speed spindle. Pick-N-Place™ software eases and shortens programming setup time. Several design features add stability and further support operator ergonomic considerations. Part sizes can be 3” (75mm) in diameter, up to 8” (200mm) in length.
The T93XM-A adds capability for lights out or unattended applications. These automation-ready units are available with probing, part-staging, automatic wheel dressing, oil filtration to 1-micron, and precision chilling options. The T93XM-A can accommodate parts up to 1” (25mm) in diameter, and 6” (150mm) in length. Simulation tools provide hindsight to avoid scrap and downtime. High-capacity pallets, which are separate from the grinding environment, further increase unmanned machining time.

- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- dressing
dressing
Removal of undesirable materials from “loaded” grinding wheels using a single- or multi-point diamond or other tool. The process also exposes unused, sharp abrasive points. See loading; truing.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- shank
shank
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
