Grinding Machine | operation | working principle,
Grinding is a metal cutting process in which the material is removed from the workpiece by the abrasive action of rotating cutting tool known as a grinding wheel which rotates at a high speed (v= 10-80 m/s) while the work is fed past the wheel at a rate of 0.2 m/s to 0.6 m/s. It has some similarity with up milling operation except that the cutting points are irregularly shaped and randomly,Grinder Safety -Hazards, Precautions, PPE - Safety Notes,Aug 10, 2019· All pedestal/static grinding machines must have an efficient starting and stopping device, which is easily accessible. Each grinding machine shall be inspected regularly before use, and colour coded; Abrasive wheels, grinding or cutting discs without the manufacturer’s maximum RPM marked shall not be used.BASIC PRINCIPLE OF GRINDING - Mechanical engineering,,Aluminum oxide grinding wheel is commonly used in making the grinding wheel and will be best suited for grinding the ferrous metals having high tensile strength e.g. hard steel, wrought iron etc. ; Silicon carbide grinding wheel is used to grind the softer, low tensile strength, high density and non-ferrous materials such as brass, aluminum and softer bronze.
