Diamond Reactivity with Air at High Temperatures Handbook of Machining with Grinding Wheels

Diamond reacts with air at temperatures above 650°C. Therefore, the wheels must either be fired at low temperatures, or in an inert, or reducing, atmosphere. Very low temperature bonds, however, FIGURE 6.10 Hot pressed fully densified vitrified diamond bond structure.

Rotationally Adjustable Tools Handbook of Machining with Grinding Wheels

Tools are available called “Rotoheads” or Norton’s “U-dex-it” that are specifically designed so that the head can be rotated without loosening the tool in the holder. The diamond is centrally positioned in the holder to within 25 pm. 7.2.9 Profile Dressing Tools For profiling applications, chisel-shaped tools with well-defined radii are used. These are used Read more
