Magnets and magnet systems


 

Electro magnetic chucks with transverse pole distribution especially for grinding


This chuck is universal with good magnetic holding, and is suitable for all kinds of work on grinding machines or milling machines depending on their pole spacing..

Multiple chucks can be combined to create very large clamping surfaces.

Characteristics:
• stable construction
• no heating of the magnet even after long hours of use
• a long working life due to the watertight integrity of the coil
• Ingress Protection: IP 67
• Input voltage 110 V DC, other voltages can be supplied on request
• two end stops are included 
• especially suitable for series praduction

This chuck requires a controller for its operation, which supplies the appropriate voltages for the magnetisation and demagnetisation process of the chuck.
