Spare Parts: Grinding Units

The unique design of the TRU TECH Perimetric Grinding Units removes the need for indicating — 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 is within millionths, as well as the concentricity ground within millionths — all without indicating.

The flexibility of these units allows grinding of various shapes and forms all on a wide variety of materials. Diameters as small as .001” and up to 5” can be accommodated. The value-added features allow for reduced set-up times and increased production.

PP8000

This ultra-precision Perimetric Grinding Fixture is extremely versatile and accurate. Featuring a 3” wide regulating roller, it’s guaranteed to less than 30 millionths (< 1 micron) run-out. This is an ideal solution when concentricity and roundness on a core pin, cutting tool blanks, or any other round tooling is critical.

Capability

Profile grind, plunge grind, peel grind, in-feed and thru-feed grind
Concentricity: < 0.00003” (less than a micro) without indicating

Options

Roller widths of .500”, 1.00” 2.00”
Thru-feed centerless grinding package
Single or dual point diamond dressing for vitrified/conventional wheels
Variety of regulating roller widths and spacers, base plates and magnetic sine bar mounts for various surface grinders

Features

Standard 3” wide regulating roller
Variety of carbide-tipped work blades, stop arms, bearing arms, wrenches and more included
Tooling for parts up to 200mm in length, optional tooling for longer parts
Dressing arbor/attachment for diamond and CBN grinding wheels
3-point Perimetric workholding
Made of hard-coated aircraft aluminum and stainless steel hardware (screws, sine bars, etc.), allowing for fast, user-friendly freely moving set-ups.

TT5000

The heart of our T93X machines, this Perimetric Grinding Fixture is extremely versatile, rigid and accurate. Featuring a 5” wide regulating roller supported by a solid carbide spindle, it’s guaranteed to less than 30 millionths (< 1 micron) run-out.
