Grinding Machine: Types, Parts, Working
Working principle of Grinding Machine: The working principle of a grinding machine is quite easier to understand In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley So when we start the electric motor the motor rotates at a certain rpm (15015000 RPM, it may change according to the types of grinding This is a small grinder operated with electric power It can be easily carried anywhere Grinding can be done by holding it in hand It is used for cleaning the heavy welding jobs On one end of the motor shaft, a grinding wheel is fitted and on the other end, a handle or switch for operating the machine is fixed according to our convenience14 Types of Grinding Machines [Working, Diagram REMA double grinding machines offer various machine versions to meet the special requirements of our customers Portfolio: bench grinders, combined grindingpolishing machines, rough grinding machines, steel and pipe grinding machinesREMA grinding machines for metalworking and industry
