Grinding (Surface, Cylindrical, Tool & Cutter)

For the 83rd episode of Cutting Tool Engineering's Grinding Doc video series, Dr. Jeffrey Badger visits with Rush Machinery in Rushville, N.Y., to begin a three-part series devoted to establishing scientific truing parameters. With the help of Rush Machinery President Bill Freese, Badger conducts a series of truing tests using the Grinding Doc Grindometer.

The Grit-Grabber and Grinder Guard from Midaco Corp. are designed for virtually all grinders and buffers. According to the company, the universal design offers significant advantages in installation, operator safety, productivity and maintenance.

Swarf, which is the result of particles being removed when grinding hard or difficult-to-machine materials, tells a story.

Weiler Abrasives Group introduced its new Tiger Aluminum cutting wheels, grinding wheels and combo wheels. Tiger Aluminum wheels have been designed with a nonloading formula that keeps them from gumming up, allowing operators to get more work done in less time—without compromising durability.

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.
