PM grinding truth

A shop that switched to powder-metallurgy steel after being told it would be easier to grind has found the opposite to be true. For some facts, the shop turned to Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series. Watch the 26th episode now.

No time to dwell

During rotary plunge dressing, a shop worker would like to know if dwelling for 2 seconds is the right amount of time. Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, says it's not a matter of time.

Adept adapter question

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, fields a question from a shop truing its diamond wheels offline, then remounting them onto the non-tapered spindle without using an adapter. The shop wondered whether its tight wheel tolerances negate the need for an adapter in the 31st episode of the video series.

A sticking point

A shop that grinds tungsten carbide with resin-bonded diamond wheels sought help to settle a disagreement over how hard to stick the wheel. Now that there are machines with auto-stickers, shop staffers are even more confused. Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, offers some suggestions in the 34th episode of the video series.

Grinding Doc takes a closer look

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, takes a closer look at a string of photos he has taken at extreme magnifications to better understand what's happening to the wheel surface in a variety of grinding applications. He shares a number of those photos in the 35th episode of the video series.
