This method uses a grinding wheel rotating at high speed to scrape or polish the surface of a workpiece to adjust its accuracy using the extremely hard and fine abrasive grains that make up the wheel. AeroEdge uses a high-reciprocating type grinding machine to perform ultra-efficient, high-precision machining of difficult-to-cut materials such as Inconel and titanium. With a fine depth of cut of about 0.1 μm and a high-speed reversing table, the AeroEdge minimizes the amount of wear on the grinding wheel and the amount of heat generated during machining, and since the machining load on the workpiece is small, it also minimizes the impact on the product.
