Episode 19: Is MQL the future?
Grinding Doc Jeffrey Badger addresses whether minimum quantity lubrication is the future of grinding. Visit The Grinding Doc website for more advice from Dr.
Episode 17: Finding the sweet spot
Dr. Jeffrey Badger helps a shop weigh advice from two wheel salesmen. One says the sweet spot of a wheel is all about material-removal rates, while the other keeps talking about wheel speed. Who’s right? Visit The Grinding Doc website for more advice from Dr.
Episode 16: Spindle versus spindle
A shop has two of the exact same machines, but one has a newer spindle. The shop is thinking about putting a new spindle on the second machine, but wants to know if there is any way to determine if one spindle is stiffer than the other? Dr.
Episode 15: Wheel consumption
A shop performing continuous-dress, creep-feed grinding on nickel alloys contacted Dr. Jeffrey Badger for advice on battling burn while reducing wheel consumption. Check out Badger's response in the latest episode of The Grinding Doc video series produced by CTEplus, the Web site for Cutting Tool Engineering magazine.
Episode 14: Tired of the chatter?
In this episode of the Grinding Doc Video Series, Dr. Jeffrey Badger helps a shop resolve the chatter encountered when performing multi-pass cylindrical OD grinding. Though the shop keeps dropping the plunge speeds, nothing seems to help. What can they do? Visit The Grinding Doc website for more advice from Dr.
Episode 13: Eliminating burr
Watch the latest episode of our Grinding Doc Video Series featuring Dr. Jeffrey Badger, the expert behind Cutting Tool Engineering magazine's Ask the Grinding Doc column. In the latest installment of the video series, Badger responds to a recommendation for a wheel that will eliminate burr.
Episode 11: Too much chatter?
A grinding shop trying to grind a 0.006″ radius into a hardened steel part with a 60-grit, vitrified-bond, aluminum-oxide wheel was having trouble with burn and huge chatter. Grinding Doc Jeffrey Badger explains how to handle the situation. Visit The Grinding Doc website for more advice from Dr.
Episode 10: Overloaded wheel?
Grinding Doc Jeffrey Badger looks at improving coolant velocity for shops running into loading problems with superabrasive wheels. Such wheels, he says, are more problematic than aluminum oxide wheels that wear away more readily. Superabrasive wheels, he notes, just don't wear away very quickly. Visit The Grinding Doc website for more advice from Dr.
Episode 9: Wheel sticking
Grinding Doc Jeffrey Badger says don’t be timid when you stick your wheel. By doing so, he says, you can do more parts between wheel sticks—just be careful of the surface finish of the first few parts after sticking the wheel. Visit The Grinding Doc website for more advice from Dr.
Episode 8: Deep dress, deep cuts
Grinding Doc Jeffrey Badger urges shops to dress quickly and take deep cuts to reduce cycle times. Visit The Grinding Doc website for more advice from Dr.
Episode 7: Cylindrical OD plunge grinding offers options
Grinding Doc Jeffrey Badger offers an overview of cylindrical OD plunge grinding in the seventh installment of our Grinding Doc video series. One of the great things about cylindrical grinding is that you can really play around with your parameters, Badger observes in the report. Visit The Grinding Doc website for more advice from Dr.
Episode 6: Cylindrical OD grinding
What’s a good speed when cylindrical OD traverse grinding? Grinding Doc Jeffrey Badger worries less about the speed, more about the percentage of the wheel being used to do the roughing. Visit The Grinding Doc website for more advice from Dr.
