SMP Brand Round 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 high power neodymium magnets. Full magnetic surface throughout diameter – powerful holding over entire chuck surface. Close pole divisions – for more uniform magnetic holding of large and small parts on Lathe or Rotary Grinding Machines. Solid construction top plate – protects permanent magnetic pack from penetration of EDM fluids. Provides stronger and more rigid work surface. Lowest height of any round permanent chuck – for added clearance on larger workpieces. Magnetic field does not affect EDM operation. Milling finish on sides and ends.

Application:

·      Permanent magnetic chucks using a high-performance magnet for grinding operations on rotary grinders, cylindrical grinders, internal grinders and cutting operations on lathes.

·      The T-handle can be used in such a way that it first holds a workpiece by a weak magnetic force and after finely adjusting its holding position, it is changed to a strong magnetic force to secure the workpiece firmly.

·      Can be used for both grinding and cutting operations.

·      Work well on thin workpieces to thick workpieces.

·      Highly precise chucks with little accuracy change.
