Grinding (Surface, Cylindrical, Tool & Cutter)

Pinch grinding offers aggressive material-removal rates, excellent concentricity and low part runout when prepping cutting tool blanks.

Invited to join a 3-year academic project, a grinding wheel manufacturer turned to the Grinding Doc to determine whether such projects are worth the money and, more importantly, the time. For its part, the company is interested in evaluating its bond formulations.

The ultrafine filtration of grinding oils and cooling lubricants is a specialized "discipline" in the overall process of the tool manufacturing. With their efficient and reliable technology, the German filtration specialist VOMAT says it has earned an excellent reputation in the metalworking industry.

Kitagawa NorthTech Inc. introduces a new series of grinding steady rests. The grinding steady rests feature two models supported with turnkey design, build and installation capabilities dedicated to grinding applications. The new fully retracting KRGU steady rests and GHS steady rests are suitable for grinding camshafts, crankshafts and other cylindrical applications where accuracy and repeatability are essential.

A shop sometimes experiences burn when using a CBN wheel to cylindrically plunge-grind a part. Slowing down doesn't help. Dr. Jeffrey Badger, who writes the Ask the Grinding Doc column for Cutting Tool Engineering magazine, offers a remedy.

Highly polished flutes and gash surfaces improve chip evacuation and aid tool performance. The smoother surface enables swarf (or chips) to exit more freely, preventing chip packing and material build up during machining. ANCA has addressed this goal with innovations reportedly found only at the ANCA Group.

Most manufacturers finish their sintered ceramic parts with grinding equipment designed for metals. Tratech Corp., however, has introduced what it says is the first commercially available CNC grinding machine designed specifically for the demanding needs of machining fully sintered ceramics.

Dr. Jeffrey Badger, who writes the Ask the Grinding Doc column for Cutting Tool Engineering magazine, offers a closer look at TG grit in the 78th episode of the Grinding Doc video series.

Micron USA's new heavy-duty, dual-support centerless grinder offers 16" (405 mm) wheel width capabilities and twin-grip. This design improves on the company's existing designs and integrates the latest control technology.

A shop that cylindrically grinds steel shafts is having trouble keeping up with tighter and tighter surface-finish tolerances. Though the shop can hold the finish, roundness and size take a hit. So the shop seeks the Grinding Doc's advice.

Palmgren says its two-speed belt grinders provide the ultimate flexibility from roughing, to intermediate grinding and blending, to final finishing. By changing the belt, the grinder quickly converts from heavy stock removal to shaping, forming, snagging, deburring, chamfering and finishing operations.

U.S. toolmakers should "claim the origin of [their] products," he said during a speech at an industry event hosted by the grinding-machine and EDM builder Vollmer. Viaud-Murat pointed out, though, that manufacturers should not claim a product is U.S.-made if it isn't.
