SMP Brand Permanent magnetic chucks are manufactured from magnetised materials and exhibit a constant magnetic field without need of an electric current. Because these materials are highly magnetised materials, they do not lose their magnetic force. This also eliminates the need for electrical connections, switches, brushes, wires and power supply. The magnet is made of a special alloy and has high power and indefinite life. Alignment of the poles determines the state of the magnet (whether it is on or off). In operation, these poles are physically moved to activate and de-activate the permanent magnet. These products are best used for Surface Grinding and light duty machining because of their reliability and safety, but as the demands of the machining operations increase and the machines are scaled up, the mechanical effort required to overcome magnetic friction to turn the poles on or off becomes too great.

Manufactured with highest power dual neodymium magnets. Full magnetic surface to all edges – Very powerful holding over entire chuck surface. Through pole divisions – for more uniform magnetic holding of large and small parts. Solid construction top plate with 2mm brass – protects permanent magnetic pack from penetration of EDM fluids. Provides stronger and more rigid work surface. Lowest height of any milling permanent magnetic chuck – for added clearance on larger workpieces. Magnetic field does not affect EDM operation. Milling finish on sides and ends. Angled backrest and end stops for better alignment of jobs on surface.

Application:

·      5-sided machining is possible in one clamp.

·      Energy saving, no electric power supply during clamping.

·      Workpieces larger than table surface are Machinable.

·      Reduced consumption of tools.

·      Light switching force due to improved structure design.

·      Improved finishing and greater accuracies.

·      More convenient and high efficiency.

·      Highly concentrated magnetic field with low flux depth.

·      Coolant and water proof structure.
