Glebar Inc. says the GT-610M is an affordable, compact, high-precision centerless infeed/through-feed grinding system, built for the machine shop. The GT-610M includes independent upper and lower slides, and a blade height ramp system for finite blade adjustment. Combining these features with its 8-5/8" wide x 10" diameter work wheel, it is able to remove more material faster, and with better surface finishes, than competing machines with narrower grinding wheels. It is able to grind spool valves, bar stock, pins, bushings, metals, hard and green ceramics, and other engineered materials, with a smaller footprint than competing machines.

Starting with a twin grip super precision spindle supporting a larger regulating wheel, 6" in diameter and 10" wide, the rigidity in this small package is second to none. A servo-driven, close-coupled drive offers the operator a high degree of control over the parts being ground.

A 7.5-hp motor drives the 10" (254 mm) diameter x 8-5/8" (219 mm) wide grinding wheel 6400 SF. The design of the work head assembly allows a single operator to replace the grinding wheel in under 15 minutes.

The system's two independent slides, which control the regulating wheel position and the work rest blade position, provide for a much easier and accurate setup than competing systems.

The GT-610M has been tooled to grind materials ranging from polycrystalline diamond tools and hard carbide to titanium bar stock, and everything in between. A test grind of 12 foot (3.6m) long, 1" (25mm) diameter titanium bar-stock on the GT-610M easily held a total diameter tolerance of 0.0002" (0.005mm), while removing 0.012" (0.3mm) per pass. Diameter roundness of 0.00007" (0.002mm) was achieved.
