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. Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, explains how to handle the situation in the 11th episode of the video series.

Flowdrill Inc. provides a video demonstration of its thermal drilling process. The company produces tungsten-carbide bits and roll-form taps to thermal drill and then thread holes in malleable materials.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, looks at improving coolant velocity for shops running into loading problems with superabrasive wheels. Such wheels are more problematic than aluminum oxide wheels that wear away more readily, Badger reports in the 10th episode of the video series.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, tells shops not to be timid when sticking a wheel. By sticking aggressively, shops can do more parts between wheel sticks, the Grinding Doc suggests in the 9th episode of the video series.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, urges shops to dress quickly and take deep cuts to reduce cycle times in the 8th episode of the video series.

Machining molds typically involves creating complex contours and fine surface finishes. Molds are high-value items usually produced in single-digit volumes, making gradual process development and scrapping parts a costly exercise. Moldmakers' customers generally want to get their products to market as fast as possible, so lead times can be short and inflexible. Finally, overseas competition puts added pressure on U.S. shops. Moldmakers are facing the challenges with a combination of technology and teamwork, and CAD/CAM software is a key competitive tool.

When cylindrical OD plunge grinding, Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, says you can play around with the parameters without affecting cycle time. Watch the 7th episode of the video series now.

When Seco Tools Inc. moved into its new headquarters in Troy, Mich., in July 2008, the toolmaker not only changed buildings, it also changed its corporate culture. Eighteen months after the facility opened, the company is still finding new uses for the modern, light-filled, 81,000-sq.-ft. building, according to Bob Goulding, manager of component engineered tooling and custom tooling.
