The Electro-Matic Products Co. was a manufacture of linear positioning systems and electrical transformers. Founded in 1938, their initial product was the development of the first chuck control to effectively neutralize magnetism for ease of removing parts from an magnet chuck, commonly used on surface grinders. Their NEUTROL chuck was used for work holding in the grinding industry. Their trademarked NEUTROFIER was the controller for their system. Additionally their DEGAUSSATRON series demagnetizers were capable of demagnetizing massive parts in a time-efficient manner.
