A motor is used to be a power unit that can convert electric current into mechanical one to make sure that your grinding machine is running riot with enough power.

Step-2

When a motor starts it rotates the grinding wheel of the bench grinder and discs present at both ends of the machine are used for the grinding purpose. In double side disc wheels there is only one motor to serve both the wheels at the same time.

The shaft used in the rotating rode is stored with the ball bearings which helps the wheels to rotate without any retarding force.

Step-3

Most of the bench grinding machines are based on visual control panels beside them to adjust the speed of the grinding wheel. When you start the grinding work you need to have some water present beside you because the high speed grinding work can catch fire.

So, to overcome any kind of fire problem you need to be aware of all kinds of errors and always have a bucket of water alongside in order to achieve successful grinding work.
