Operation of Milling ( Machine ) These are the following different operations that can be performed in the milling ( machine ):- 1. Face milling operation. This is an operation for producing a flat surface, which is perpendicular to the axis of rotating cutter. The operation is perform by the face milling cutter. 2. Plain milling operation
9. Grinding. Grinding operation may be performed in a drilling machine to finish a hardened hole. The grinding wheel is made to revolve with the spindle and is fed up and down. A suitable grinding wheel may be selected for surface grinding operation. Grinding can also be done correctly out of roundness of the hole.
Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece, they act as tiny cutting tools, each particle cutting a tiny chip from the workpiece.
To perform the operation, the work and the cutter are secured properly on the machine. The depth of cut is set by rotating the vertical feed screw of the table. And the machine is started after selecting the right speed and feed. Face Milling The face milling is the simplest milling machine operations. This operation is performed by a face ...
