Workpiece clamping \ Technical introduction – magnetic clamping technology

Magnetic clamping plates and accessories

The magnetic clamping range includes permanent-magnetic, electro-per- 
manent magnetic and electro-magnetic systems, exclusively for clamping
ferromagnetic materials. Magnetic clamp types:
Advantages of the magnetic clamping technology over other clam- To satisfy diff erent requirements, clamping plates with diff erent magnetic sys-
tems are available:
ping techniques:  Permanent magnetic clamping plates
 Shorter setup and clamping times:  Generation of magnetic force via permanent magnets
 Workpieces can be easily and accurately aligned  “Low magnetic fi eld; regulation of holding force possible”
 Clamping plates can be switched on/off quickly and easily, as can the round  Mechanical, manual on/off switching
chuck
 Simultaneously clamp and machine several workpieces  Electro-permanent magnetic clamping plates
 Generation of magnetic force via permanent magnets with excitation winding
 Workpieces are accessible from diff erent sides with a single clamping  Electric on/off switching with current pulse. Control unit is required.
operation  Regulation of holding force, de-magnetisation and machine release
 Increase in accuracy and surface quality:  Maximum precision as no mechanical movement or heat development
 The workpiece is supported across the full contact surface  Electromagnetic clamping plates
 Distortion-free clamping  “Generation of magnetic clamping force via excitation windings; high
 Workpieces become plane and parallel magnetic fi eld”
 No vibration during machining  Electric on/off switching with current supply Control unit is required
 Longer tool service life, as no vibration produced  Regulation of holding force, de-magnetisation and machine release

Application:  No deformation during switching operation due to
For high-precision grinding and eroding work. special switch method
 Sealed against coolant and dielectric
Execution:  Easy switching using hexagon key
 double neodymium magnetic system generates an
adhesive force of up to 100 N/cm 2 Delivery:
 Universal clamping of extremely small, thin and 2 limit stop strips, 2 adjustable clamps and hexagon
