Grinding is a metal cutting operation like any other process of machining removing metal in comparatively smaller volume. The cutting tool used is an abrasive wheel having many numbers of cutting edges. The machine on which grinding the operation is performed is called a grinding machine.

Grinding is done to obtain very high dimensional accuracy and better appearance. The accuracy of grinding process is 0.000025mm. The amount of material removed from the work is very less.

According to the accuracy of the work to be done on a grinding machine, they are classified as

  1. Rough grinding machines
  2. Precision grinding machines

Rough Grinding Machines

The rough grinding machines are used to remove stock with no reference to the accuracy of results. Excess metal present on the cast parts and welded joints are removed by rough grinders. The main types of rough grinders are

  1. Hand grinding machine
  2. Bench grinding machine
  3. Floor stand grinding machine
  4. Flexible shaft grinding machine
  5. Swing frame grinding machine
  6. Abrasive belt grinding machine

Precision Grinding Machines

Precision grinders are used to finish parts to very accurate dimensions. The main types of precision grinders are:

  1. Cylindrical grinding machines
  2. Internal grinding machines
  3. Surface grinding machines
  4. Tool and cutter grinding machines
  5. Special grinding machines
