Episode 5: Cluster diamonds
Thinking about using cluster diamonds? Grinding Doc Jeffrey Badger suggests going at least 4x faster than with a single-point diamond. Visit The Grinding Doc website for more advice from Dr.
Episode 3: The right grit
In the third episode of the Grinding Doc video series, Jeffrey Badger, Ph.D., takes a look at a common problem shops have with getting the surface finish that they want. Visit The Grinding Doc website for more advice from Dr.
Episode 2: Ceramic abrasive luck?
In the second episode of our Grinding Doc video series, Dr. Jeffrey Badger fields a question from a shop that hasn’t had any luck with ceramic abrasive. Visit The Grinding Doc website for more advice from Dr.
Episode 1: Coolant velocity versus flow rate?
The debut episode of Cutting Tool Engineering magazine's Grinding Doc video series fields a question from a shop wondering about the relationship between coolant velocity versus the flowrate. Dr. Jeffrey Badger, who writes the Ask the Grinding Doc column in Cutting Tool Engineering magazine, takes a look at the coolant issue for CTE Plus.
Episode 32: Grit size
Dr. Jeffrey Badger helps a shop struggling to maintain a 16 µin Ra surface finish using a 60-mesh grit size. On the advice of the wheel supplier, the shop tried 100- and 120-mesh grits only to end up with burned parts. Visit The Grinding Doc website for more advice from Dr.
Episode 12: Burn noticed
Dr. Jeffrey Badger, a grinding consultant and author of The Grinding Doc column in Cutting Tool Engineering magazine, helps a grinding shop distinguish between true thermal damage and surface burn. Visit The Grinding Doc website for more advice from Dr.
Episode 22: High-porosity wheel to the rescue?
A shop with burn issues wants to know if a high-porosity wheel would reduce temperatures as suggested by the company's wheel supplier. Dr. Jeffrey Badger, the columnist for Cutting Tool Engineering's Ask the Grinding Doc column, offers some guidance in the 22nd episode of our Grinding Doc video series.
Episode 18: Feeling the burn
In episode 18 of the Grinding Doc video series, a shop experiencing more wheel wear and burn after switching from one high-speed steel grade to another with lower grindability—requiring slower feedrates—seeks a recommendation for a wheel that won't require the shop to increase cycle time. Dr.
Episode 4: Rotary diamond dressing
Grinding Doc Jeffrey Badger offers insight into rotary diamond dressing for a shop whose parts turn to toast. Visit The Grinding Doc website for more advice from Dr.
TungForce-Rec Indexable Miniature Shoulder Milling Cutter
Tungaloy Corp. offers TungForce-Rec, the indexable miniature shoulder milling cutter. The TungForce-Rec insert has a unique V-shaped bottom to enhance the insert's resistance to centrifugal force, assuring reliability and high productivity during high-speed machining, according to the company.
MillQuadFeed High-Feed Milling Cutter
Tungaloy Corp. offers MillQuadFeed, a new high-feed milling cutter. With a depth of cut up to 0.098" (2.5mm) and a feed rate up to 0.078" (2.0mm) per tooth, MillQuadFeed accomplishes astounding metal-removal rates in rough milling operation, according to the company.
DoTriple-Mill Facemilling Cutter
DoTriple-Mill is Tungaloy's latest facemilling cutter, featuring an innovative dovetail clamping system that will reportedly dramatically reduce insert lift up and excessive shear force imposed on the screws during heavy-duty milling. Compared with the last generation of facemilling platforms, DoTriple-Mill delivers stable machining and consistent tool life.
