CC-GRIND-FLEX Semiflexible Grinding Discs

PFERD has introduced its CC-GRIND-FLEX, the next generation of semiflexible grinding discs. This high-performance disc blends weld seams on large surfaces without leaving dents or bumps typical of a rough grinding wheel or fiber disc. When using the CC-GRIND-FLEX, an absolutely flat surface can be achieved.

Episode 87: Matching coolant velocity to wheel velocity

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.

Episode 86: Cup wheel grinding wearing thin

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.

Episode 85: Defining truing parameters, part three

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 demonstrates CC-GRIND-SOLID grinding wheel

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.

Norton QUANTUM3 Combination Wheels

Saint-Gobain Abrasives offers its new Norton QUANTUM3 combination Wheels addition to the recently introduced Norton QUANTUM3 (NQ3) line of depressed-center grinding wheels. In comparison tests, NQ3 combo wheels have several key benefits over competitive wheels. NQ3 Combo Wheels have 50 percent longer life, which significantly reduces the need for wheel changes and results in decreased production downtime and less labor cost. Due to more efficient and faster cutting and grinding capabilities, the new combo wheels increase productivity by 15 percent over competitive wheels, so users can finish more pieces in less time, according to the company.

Tiger Aluminum Cutting, Grinding and Combo Wheels

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.

B5490 Epoxy Bond

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.
