Step 1
Outline one method of securely holding ferrous metals during the surface grinding process.
Answer
One effective method of securely holding ferrous metals during surface grinding is the use of a magnetic chuck.
A magnetic chuck is equipped with permanent magnets that provide a robust way to clamp ferromagnetic materials. It consists of a plate that can generate a magnetic field strong enough to hold the workpiece tightly against it.
The magnetic surface is activated by an on/off control that allows easy placement and removal of the workpiece. Electromagnets can also be utilized for more flexibility and control, particularly in varying sizes and shapes of workpieces.
