What isInternal Grinding ?

  • Internal grinding is a machining process that uses an abrasive wheel to remove material from the inner surface of a cylindrical workpiece.
  • This process is used to achieve precise dimensions, smooth surface finishes, and accurate geometric features within internal holes, bores, and cavities.
  • With careful selection of grinding wheels, coolant systems, and grinding parameters, internal grinding delivers exceptional results for a wide range of applications.

Types of Internal Grinding

Internal grinding is a critical machining process for producing high-precision internal surfaces in cylindrical workpieces. Its versatility, precision, and ability to achieve fine finishes make it an essential tool in various industries.

Internal grinding can be categorized based on the workpiece’s orientation and the grinding wheel’s movement:

1. Straight internal grinding: The workpiece remains stationary, and the grinding wheel moves longitudinally along the internal surface.

2. Angle internal grinding: The workpiece is tilted at an angle, and the grinding wheel moves along the internal surface at an inclined angle.

3. Oscillating internal grinding: The workpiece remains stationary, and the grinding wheel oscillates back and forth along the internal surface.

4. Helical internal grinding: The grinding wheel rotates while also moving along the internal surface, creating a helical grinding pattern.
