Diamond wheels

Diamond wheel specifications show diamond concentration in the grinding rim a concentration of 100 equals 25 vol % diamond. Most wheels have diamond concentrations in the range of 50 to 200 and selection depends on use. Lower concentrations work best on wide contact surfaces higher concentrations work best on narrow edge widths (47). 

Stainless steel microelectrodes were prepared by sheathing 100-pm diameter stainless steel wire in glass. Tips were polished on a precision diamond wheel. Electrode response to variation in cathodic depolarizer concentration was confirmed by exposure to solution containing up to 6 mM HjOj. The increase in for the electrode was comparable to the change observed for sample coupons exposed to the same H2O2 concentrations. The electrode was conditioned by exposure to the influent reactor solution for several hours before measuring E, within the biofouling deposits.

Superabrasive wheels include diamond wheels and cubic boron nitride (CBN wheels. 

In order to keep the polishing rate constant during the long CMP steps, in situ conditioning of the polishing pad using diamond wheels is often a characteristic of a microfabrication process. To control the process more precisely, an end-point detection system that can measure the remaining layer thickness is extremely useful. 

In this test a notch of initial depth c is introduced, usually by using a diamond wheel, on the tensile side of a flexure specimen (Fig. 11,6a). The sample is loaded until failure, and c is taken as the initial crack length. Fracture toughness K c is calculated from... 

Early Results and Comments. Figure 3 is a TMAFM image of a dispersed clay on a polished sapphire substrate in DI water. The particles are phlogopite from Ontario, Canada. Fine grains of phlogopite were obtained by grinding a sample on a fixed diamond wheel, from which the size fraction below two microns diameter was separated out using sedimentation techniques.
