Magnetic Clamping Devices
Magnetic clamping devices such as magnetic chucks, rotary chucks and blocks are used in all sectors of metalworking. When grinding, milling, eroding and in metrology, magnetic clamping devices have proven daily by high precision, distortion-free clamping and durability. In the following overview you will find a wide range of magnetic clamping devices for different applications. In addition to our wide range of standard equipment, we also offer special solutions for your individual clamping problem.

The holding forces indicated refer to a test work with 40x40x20mm and sanded surface of St37.
The following factors reduce the holding force:
Poor surface/air gaps
Poorly magnetizable materials such as cast iron or alloy steel
Full-surface occupancy of the magnetic disk (the total holding force increases, the holding force however drops per cm2)

Permanent magnetic chucks type PMNM are high precision plates for clamping small and thin parts for precision grinding and eroding. The low magnetic field height prevents magnetization of the processing tools. The chipboard is activated via a removable hex shifter.
Structure:
Neodymium magnet system, steel body
transverse pole pitch 1.4 + 0.5mm
Holding power 100 N/cm2
Magnetic field height 5mm
Pole plate wearing limit 6mm
permanent magnet chucks have the same magnetic properties as the proven PMNM and may be used by construction, both with the horizontal and vertical magnetic clamping surface. PMNM-W are suitable for grinding edges of plates for angle-grinding of blocks and wire EDM. In use, the PMNM-W is simply clamped in the rule to the electromagnet plate the surface grinder.
Structure:
Neodymium magnet system, steel body
transverse pole pitch 1.4 + 0.5mm
Holding power 100 N / cm2
Magnetic field height 5mm
Pole plate wearing limit 6mm
Recommendation:
High-precision chuck for grinding and eroding
Permanent Magnetic Circular Chuck Type RM, with reinforced ceramic magnet system can be used for clamping bulky and heavy workpieces. The magnetic force is infinitely variable, in the surface incorporated centering grooves facilitate alignment of the workpiece. In the rake face, a center hole can be introduced.
Structure:
Ceramic magnet system, Aluminum body,
Max Pole pitch 5+8mm
Holding power 140N/cm²
Magnetic field height 8mm
Pole plate wearing limit 8mm
Switch travel MAG-ENT-MAG 500°
Recommendation:
Super Strong circular chuck for turning, also for rough parts
Low Cost Arc Permanent Ferrite Magnet Y10T
Small Motor Sintering Ferrite Arc Magnets
Round Base NdFeB Magnet Ø22 X 6.9mm
