Dr. Jeffrey Badger, author of the "Ask the Grinding Doc" column in Cutting Tool Engineering magazine and host of CTE's Grinding Doc Video Series, previews his 3-day High Intensity Grinding Course.

A machinist wrote to Dr. Jeffrey Badger, author of the "Ask the Grinding Doc" column in Cutting Tool Engineering magazine, because the "old-timers" in the shop tell him he has to dress at the same wheel speed he uses to grind. The machinist wanted to know if that was true, and, if so, why?

With rising energy costs, new laws and a new environmental conscience, the topic of energy efficiency of production machinery is increasingly being discussed and influences more and more purchasing decisions. The same holds true for filtration systems designed to clean cooling lubricants in the tool manufacturing process.

A shop surface grinding 12" x 36" plates has to remove 1/8" of material on both sides, but the cycle time is a killer. To find a way to reduce the cycle time, the shop turned to Dr.

The sweet spot is where the grits in a grinding wheel optimally penetrate the workpiece to form a chip -- not too deep and not too shallow.

Norton | Saint-Gobain has introduced a major upgrade to its Norton Gemini RightCut Wheels, reportedly providing an optimal aluminum oxide option for cutting steel and ferrous metals.
