Electrochemical machining (ECM) is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl).
Though machine designs vary, the basic hammer mill working principle remains the same—uniform size reduction of aggregate raw material is achieved by repeated blows with hammers mounted to a rotating shaft. Whether coffee beans or titanium, hammer mills can effectively grind, shred, shatter, or pulverize any raw material to the desired ...
Mechanical Grinding. A mechanical process using a rotating grinding wheel made from abrasive material containing small particles of grit ranging from fine to coarse. The wheel revolves around a central axis, making contact with the surface of the workpiece, while the particles act as cutting tools that cut chips from the material.
The principle of internal grinding is shown in Fig. 3. Internal grinding helps to grind the surface of bores whether they are plain or tapered with the help of a small grinding wheel. This process improves the geometry of the hole as well as the surface finish. A …
