Grinding is a combination of rubbing ploughing and cutting actual chip formation . A certain level of grit penetration into workpiece is required before chip formation can start. Magnitude of critical grit depth of cut required to initiate cutting becomes less with the increase of grinding velocity.
Special types of grinders are grinding machines made for specific types of work and operations for example Tool and cutter grinders. These grinding machines are designed to sharpen milling cutters reamers taps and other machine tool cutters. The general-purpose cutter grinder is the most popular and versatile tool-grinding machine.
The grinding machine is controlled by stepless speed regulation system which can easily adjust the grinding speed suitable for grinding various parts. The gas pressure proportional valve closed loop feedback pressure control can be used to control the pressure device independently. On the plate is set to slow down function effectively prevent the broken water workpiece.
Do make sure your bench grinder has an adjustable work rest that is kept adjusted to 18 inch or less from the wheels grinding face. OSHA 1910.215a4 Work rests. On offhand grinding machines work rests shall be used to support the work. They shall be of rigid construction and designed to be adjustable to compensate for wheel wear.
Always utilize the right kind of grinding wheel for the material being grinded. Never grind non ferrous materials. The work rest must be set at an adequate distance from the abrasive wheel. The grinding wheels must be regularly serviced. Ensure that the machine attains full speed before grinding. Never push the workpiece against a cold wheel.
