Machining of micro flat drill and. substrate for grinding part. f In the flank surface grinding, the rotary table, as well as the tool. blank, was rotated and fixed by an angle corresponding to the. desired drill point angle. For the cylindrical surface grinding, the tool blank was ground. by feeding the grinding wheel linearly in the Z direction.
Micro grinding is an effective process to achieve ductile cutting of the brittle difficult-to-cut materials and low cost compared to the electro discharge machining (EDM) or the laser machining . The process can also shorten processing time and save energy because it can fabricate micro features with good surface quality without the additional ...
Micromachining is a machining technique employed to produce parts smaller than 0.015" in diameter. It requires specialized abrasive tools with 1/3rd size of the thickness of a human hair to achieve desired dimensions and surface finishes. A heavy upsurge in demand for Micro Machining was seen in the late 1990s with advancements in semiconductors.
