Plane grinding

Grinding method to create a flat surface on a workpiece using a rotating grinding wheel that removes parts of the material.

The process

The workpiece is placed in a fixture under the rotating grinding wheel. The wheel then moves horizontally across the material and grinds down the workpiece surface in one or more steps until the desired thickness or surface roughness is achieved. To avoid that the material becomes too hot due to friction a coolant (cutting fluid) is often used.

The machine can be manually operated or CNC.

Cutting fluid
Cutting fluid has three main purposes. Cooling, lubrication and removal of chips.
