For the 43rd episode Cutting Tool Engineering magazine's Grinding Doc Video Series, Dr. Jeffrey Badger helps a shop having trouble getting its CBN wheel to open up before it burns the first few hardened steel parts, which then must be scrapped.
For the 44th episode of the Grinding Doc Video Series, a shop recently asked Dr. Jeffrey Badger, Cutting Tool Engineering magazine's Ask the Grinding Doc columnist, to settle an argument about the best way to run the dresser when rotary plunge diamond dressing aluminum-oxide wheels.
A shop is grinding hardened steel, and periodically switches between a CBN wheel and an aluminum-oxide wheel. Given that the shop is getting pretty much the same material removal rate, surface finish and cycle times with both wheels, the shop is beginning to wonder if it's really worth it to use a CBN wheel.
Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, responds in the 45th episode of the video series.
A shop using electroplated grinding wheels observed a horrible surface finish on the first several parts produced by a new wheel. Though the surface finish gradually improves, the shop turned to the Grinding Doc for a solution to the problem.
Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, takes a look at the problem in the 46th episode of the video series.
In the 47th episode of Cutting Tool Engineering's Grinding Doc Video Series, the Grinding Doc—Dr. Jeffrey Badger—suggests that a shop look at its dressing policy if it hopes to reduce its wheel consumption.
Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, fields a question from a shop grinding hardened steel with a CBN wheel. Though the shop is using a high-pressure cleaning nozzle, it doesn't seem to help much. The shop wants to know how much pressure they need in the nozzle?
A shop creep-feed grinding hardened steel using a water-based coolant kept running into trouble after grinding for a few hours. Everything would be grinding along fine, but then—WHAM—really bad burn would bring the job to a halt. And the burn wouldn't go away until the shop dressed the wheel again.
Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, provides some insight and a solution in the 65th episode of the video series.
A shop seeks relief from the burn experienced during its creep-feed grinding operations. Given that slowing down the feed rate only helped a little, and only for a short time, the shop sought an alternative solution from Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series.
A shop that cylindrical-grinds tungsten-carbide is running into trouble maintaining optimal parameters when switching to a larger diameter. Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, offers some insight.
Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, fields a question from a shop hoping to find a faster way to find the sweet spot when cylindrical-plunge grinding tugsten-carbide shafts.
