    14. Electromagnetic Chuck An electromagnetic chuck is an indispensable attachment for surface grinding machine. It requires a perfect flat mounting surface to be clamped onto the machine table; otherwise, table will be subjected to disformation due to the huge magnetic attracting force of chuck. The following practice must be followed to grind the mounting surface of magnetic chuck before it is clamped onto the machine table.
