Ultra-precision grinding - ScienceDirect
Another type of micro-pencil grinding tool is a sintered tool where the grains are bonded in a sintered bronze layer on a tungsten carbide blank. Typically, sintered tools have diameters of about 200 μm . A third type of micro-pencil grinding tool is CVD coated. Here a blank is coated with poly-crystalline diamond grinding layers.

Modeling of curved diamond wheel errors for improvement of ...
A superhard diamond grinding can machine the hard and brittle freeform workpiece, but it is difficult to control the form-truing errors of curved wheel-profile in multiaxial grinding. Generally, it needs multiple compensation grindings through the on-machine measurement of the ground surface, leading to inefficiency. Hence, the model of 2D wheel-profile errors is proposed to directly ...

Grinding Precision and Productivity Reach New Heights
Grinding, like all machining processes, is generally thought of as a process of tradeoffs. To gain one attribute, you have to sace another. However, that is not always true. For example, one logical attempt to achieve good material removal rates as well as limited wheel wear is to fix diamond or CBN super-abrasives in a sintered metal bond.
