Ultrafine grinding process is accompanied by high energy consumption and severe abrasion of devices. In addition, when particles are excessively small, they will become coarser rather than finer through agglomeration if we continue …
A developed grinding system employing super-fine abrasive wheels was used to fabricate ultra-fine microtools having a variety of shapes. The machine successfully produced a cylindrically shaped micro-tool having a tip diameter of less than 1 μm.The surfaces of the produced micro-tools were investigated by advanced analytical methods.
