Flat/surface grinding

Flat or surface grinding produces surfaces that are either fully flat or run linear in the main feed direction of the grinding wheel.

Flat or surface grinding is subdivided into:

  • Peripheral grinding in deep grinding
  • Peripheral grinding in pendulum grinding
  • Face grinding



Peripheral grinding in deep grinding

Deep grinding is a method of grinding where the feed motion is relatively large and the feed rate is correspondingly small.
The workpiece shape is ground with a large feed motion, or from the solid material.
Deep grinding is used for machining turbine blades, slots or profiles, rotors, and camshafts.

Use with:

  • Open-pore peripheral wheels with low hardness

Advantages compared with pendulum grinding:

  • Better surface finish of the workpieces
  • Less wear on the grinding wheels
  • Shorter grinding times as there are no empty runs or table reversing times



Peripheral grinding in pendulum grinding

Reciprocating feed motion. The feed motion takes place progressively in small steps with a relatively fast feed rate. Peripheral grinding in pendulum grinding is used for machining shafts, rolls, and shanks.

Use with:

  • Peripheral wheels



Face grinding

Use with:

  • Cup wheels
