Grinding Wheels

How do you know your coolant velocity? The Grinding Doc says the best — and perhaps most accurate — way to determine coolant exit velocity is with the Ol’ Bucket & Stopwatch Technique. It’ll take five minutes and tell you how close you are to wheel speed.

This is the 87th episode of the Grinding Doc video series, which is a monthly video series produced by Cutting Tool Engineering in collaboration with Jeffrey Badger, Ph.D., a grinding consultant and author of the Ask The Grinding Doc column in CTE.

For the 86th episode in the Grinding Doc video series from Cutting Tool Engineering, Dr. Jeffrey Badger encourages shops to true a taper in the wheel when they perform cup wheel grinding.

Thanks to a collaboration between Dr. Jeffrey Badger and Rush Machinery in Rushville, N.Y., shops now have some practical guidelines when it comes to truing parameters. Badger shares some of this new-found advice in 85th episode of Cutting Tool Engineering's Grinding Doc video series. 

PFERD Inc.'s CC-GRIND^®-SOLID for controlled rough grinding applications integrates a fibreglass backer and a high-performance coated abrasive that is said to be 40 percent more productive than reinforced grinding wheels. To illustrate the point, PFERD filmed a demonstration comparing the CC-GRIND-SOLID to one of its own conventional rough grinding wheels and that of a competitor.
