As my previous article of Grinding Machine, I told, grinding is an important operation in manufacturing industry to get a final product, so for that, we need to know about the grinding wheel and its properties so that we easily choose a right wheel for the right material.. I assumed that you already have a brief idea about Grinding Machine. Don't worry! if you not learned yet …
Fabrication of SiC microchannels by thin diamond wheel grinding. In the present study, a conventional vertical milling machine is utilized to fabricate the SiC microchannels instead of traditional grinding machines, as shown in Fig. 2.The maximum wheel speed of the vertical milling machine is 75.46 m/s, and the positional accuracy is 0.1 μm.
The wafer grinding machine uses a centrally located robot to move a wafer from an input station to a measuring station. Thereafter, the wafer is moved into a grind station and a wash station sequentially. The robot is able to move a wafer from the wash station to either the measuring station for after-grinding measurements or directly to an output station.
Fig. 2 shows the truing principle of diamond grinding wheels. It can be observed that a green silicon carbon (GC) truing wheel is driven by a motorized spindle, which is fixed on a custom-made online truing device that rotates at speed n.A diamond grinding wheel is driven by a high-speed aerostatic spindle with a wheel speed N.
