Why One Conditioning Stick Outperforms Another in Carbide Grinding
A shop grinding tungsten carbide with a resin-bonded diamond wheel asked the Grinding Doc about the difference between two conditioning sticks purchased from two differrent suppliers. With one stick the shop can do a lot more parts between stickings. Why is this? Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, responds in the 20th episode of the video series.
High-speed demo
Even with a rigid setup, the high cutting forces from driving chips into the T-land face generate small vibrations, which can be seen with Federal-Mogul Corp.'s high-speed video system.
Hearing MQL talk
Is minimum quantity lubrication the wave of the future or simply another option shops should keep in mind? Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, responds in the 19th episode of the video series.
Expanding capabilities
The Cavalier Tool Co. expanded its capabilities for producing small- and medium-sized molds by investing in new machinery such as Makino's a92 machining center.
Feeling the burn
A shop experiencing more wheel wear and burn after switching from one high-speed steel grade to another that reportedly offers lower grindability—requiring slower feedrates—seeks a recommendation for a wheel that won't require the shop to increase cycle time. Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, considers the shop's options in the 18th episode of the video series.

Finding the sweet spot
One wheel sales guy says finding the sweet spot on a wheel is all about material-removal rates. Another guy keeps talking about wheel speed. A shop turned to Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, to find out who's right in the 17th episode of the video series.

Triple nickel milling
ATI Stellram and Sandvik Coromant offer demonstrations of their milling cutters as part of this aerospace report.
Spindle vs. Spindle
Faced with two machines exactly the same, except that one has a newer spindle, a grinding shop wants to know if there's a way to determine if the newer spindle is stiffer than the older one on the other machine. Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, analyzes the situation in the 16th episode of the video series.
Pinch milling
