Nitty gritty on chatter

A wheel supplier urged a shop to use a 150 mesh grit wheel to put a 0.005" radius into a part, but when the shop went from its 80 mesh grit to the smaller grit the result was horrific chatter. In fact, the shop always gets chatter from small grit wheels. For some explanation, the shop wrote to Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, for the 36th episode of the video series.

Dear Doc: I grind fine threads into hardened stainless steel with a fine-mesh aluminum-oxide wheel. The threads are 0.8mm deep in a 5mm-dia. ID. There are three threads per part. This operation just chews through the wheel, and I get only one part before I have to dress a 0.2mm depth in my 4mm-dia. wheel. What am I doing wrong?
