In this work, machining test was carried out in various machining conditions using ultrasonic vibration capable CNC machine. For work material, alumina ceramic (Al2O3) was used while for tool material diamond electroplated grinding wheel was used. To evaluate ultrasonic vibration effect, grinding test was performed with and without ultrasonic vibration in same machining condition.
machine rigidity, power demands for grinding, and improved spindle technology were the factors of machine complexity. The second major issue observed was economical aspect.
Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool. A wide variety of machines are used for grinding: Handcranked knifesharpening stones (grindstones) Handheld power tools such as angle grinders and die grinders; Various kinds of expensive industrial machine tools called grinding machines;
CNC Cam Lobe Grinding Machine is a very unique and Economical solution for Cam grinding. It is very compact, high precision, very stable for high accuracy production runs of cam shafts with convex and concave cam forms.
The hand held sensor is the vibrations of grinding operations are carried out by a placed on the object for measurement. The sensor should be dynamometer. The measured values were analysed through tightened for its stable position.

Recently developed computercontrolled twist drill grinding machines have allowed the production of precisely defined points of widely different shapes.
A nib can be made finer by grinding down both sides of the nib. The pen should be held as in Steps 1 and 2, but with the nib now resting on its side on the Arkansas stone: As in Step 3, grind the nib in the direction of a down stroke.
Grinding a crankshaft is a process of removing material from the journals in an effort to refurbish and reuse an expensive, yet vital component of an engine. It is usually done during the process of rebuilding an engine when needed, but also has some performance aspects which come along with the process.
The shaft of a jet engine is reworked by removing the original plating, and the plating adjacent the oil hole in the shaft is removed by a hand grinding operation. The hand grinder includes means for supporting the grinding wheel with means for controlling the area and depth of the grinding.
Machine tool design now plays an important role in grinding process and the authors provide chapters on important new machine tool designs and the unique aspects of centerless, ID and surface grinding .
lathes The lathe is a machine tool used principally for shaping articles of metal (and sometimes wood or other materials) by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing the cutting action.
