Grinding (Surface, Cylindrical, Tool & Cutter)

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.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, offers a checklist for shops contemplating a switch from aluminum oxide to CBN wheels. About the Grinding Doc Video Series: Thanks to his work as an independent grinding consultant and the author of the "Ask the Grinding Doc" column in Cutting Tool Engineering magazine, Dr.

What do baseball legend Ted Williams slugging his first big-league dinger, Batman comics hitting the streets and Germany attacking Poland to launch World War II have in common? They all occurred in 1939, the same year Ellis Brown, Charles W. Kling and Harold Heckamen founded Bremen (Ind.) Gray Iron Foundry Inc.

Results from testing aluminum-oxide vitrified-bond wheels and diamond wheels in three different bond systems show the proper diamond roll dresser design, application methods and wheel specification can help manufacturing engineers achieve optimal results from continuous-dress, creep-feed (CDCF) grinding.

Spend enough time working in a machine shop and you're bound to pay a visit to the emergency room for a cut finger. First comes the sting as the ER physician injects you with a local anesthetic, then the tug of the thread as she drags the suturing needle, a type of surgical needle, through your skin.

CIRO Products Ltd. introduces the Elaso ebm100 dynamic grinding wheel balancing system.

A coolant supplier having trouble getting customers to try a new product turned to Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, for some insight into how the supplier could convince shops to change coolant.

Water is an effective heat conductor, and, if you get an adequate supply of coolant within the pores of the wheel, the coolant will absorb about 70 percent of the heat.
