Grinding (Surface, Cylindrical, Tool & Cutter)

Meister Abrasives says its new HPL (High Performance Lubrication) grinding wheels rely on premium-grade CBN crystals fixed with durable, porous, intrinsically lubricated bonding matrix to allow substantially faster grinding of difficult materials without sacrificing quality due to wheel loading and/or part burning.

Walter Surface Technologies introduces the Xcavator with Comfort Max Technology - a grinding wheel that reduces grinding time while increasing operator comfort and overall plant productivity in industrial metalworking applications.

Using a Norton SG grit wheel, a shop turned to the Grinding Doc to find out why they suddenly lose form on the 7th or 8th part. To prevent bad parts, the shop dresses the wheel after every 5th part.

Marposs has announced the availability of its Marposs/Dittel M7002/MA7002 next-generation, dual-plane balancing systems for high precision grinding machines. Relying upon a new deterministic balancing algorithm and specially designed balancing head, these new units deliver an improved balancing process with significant cycle time reduction, according to the company.

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.
