SMP brand Electromagnetic chucks generate a magnetic field when electrical current is introduced. The field is created with coils supplied by direct current (DC). These chucks are activated with a control unit which allows quick magnetizing and an easy de-magnetizing of the workpiece. Electromagnetic chuck systems can be manual, automatic or combined. The grinding electromagnetic chuck could be controlled by a corresponding controller. The high performance epoxy resin filled in poles gaps could protect the chuck surface from coolant oil or water.

Application:

·      Most widely used electromagnetic chucks for surface grinding operations.  

·      SMP machining technology is used to realise a lavish body-to-case one piece hollow construction, instead of a welded construction, to enhance the rigidity, minimize secular change and improve accuracy of the chucks.

·      The chuck weight has been reduced as much as possible in consideration of driving the table of grinders.

·      This design helps contribute to a longer service life of surface grinders.

·      The chucks have been designed as low as possible to increase a workpiece mounting space on the surface grinder.

·      The overall height is as short as 80 mm to 90 mm for small and medium size magnetic chucks. Thus various types of workpieces can be held.
