Magnetic Chuck

May 10, 2025

Magnetic chuck are composed of strong permanent magnets (such as neodymium magnets). It utilizes magnetic force to firmly adsorb steel workpieces to achieve clamping, handling or positioning. Adsorption and release of the workpiece is realized by turning the handle to turn on and off the magnetic circuit, thus controlling the release or elimination of the suction force. It does not require continuous power supply, which is safe and energy-saving. Magnetic suction cups are composed of strong permanent magnets (such as neodymium magnets). 

 

Magnetic chuck

 

1. Core Advantages

 

  • Permanent magnet drive, no power consumption during operation, no risk of workpiece falling caused by power cut
  • Uniform magnetic attraction across full surface, less workpiece deformation compared with mechanical clamping
  • Open structure, larger processing range, tool can approach workpiece from multiple directions
  • High flatness working face, suitable for precision grinding and finish milling processes
  • Simple operation: switch handle to turn ON / OFF magnetism, fast loading & unloading
  • Multiple models: standard pole for rough machining, fine pole for thin plate & precision finish machining
  • Sealed internal structure, effectively resist cutting fluid, coolant infiltration
  • Custom size, ultra-large size and special pole pitch design available
