Grinding (Surface, Cylindrical, Tool & Cutter)

Buffalo Abrasives Inc. says the B5490 is an epoxy bond that is durable and easy to use, designed to run cool, generating less heat, thus less chance of burning. The bond eliminates chatter by providing a softer, more-forgiving grinding action.

For the 82nd episode of Cutting Tool Engineering's Grinding Doc video series, Dr. Jeffrey Badger explains why using the Barkhausen Noise Signal to assess grinding burn is a tricky business.

Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.

In the August 2017 issue of Cutting Tool Engineering, Ask the Grinding Doc Columnist Jeffrey Badger, Ph.D., fields questions about spotting wheel loading, white sticking for hardened steel loading, and what causes barber pole marks during cylindrical-traverse grinding.

Marposs has announced the availability of its P1dWB, an entry-level grinding wheel balancing and process monitoring system. This new system is intended to replace Marposs' electronic systems E78 and E82.

Dr. Jeffrey Badger examines why many shops experience pain when cylindrical grinding a face, or shoulder, in the 81st episode of the Ask the Grinding Doc video series, which is produced in collaboration with Cutting Tool Engineering.

Everyone's talking about it – the fourth industrial revolution. Rollomatic S.A., based in Le Landeron, Switzerland, is one of the companies setting a course for an interconnected future for machinery. After all, although precision is still a top priority for Rollomatic customers, aspects such as monitoring of machinery and production processes from anywhere in the world are growing more important by the day.

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.
