MAGNETIC CLAMPING TECHNOLOGY IN THE METAL PROCESSING

Magnetic clamping technology is used in all areas of metal processing. In grinding, milling, eroding and metrology, magnetic clamping devices prove themselves every day through high precision, distortion-free clamping and durability.

  • Clamping with short setup times
  • Flexible and universal
  • Large holding forces
  • High clamping forces
  • Adapted to the workpiece contour
  • Precise quality

MAGNETIC CHUCKS

Rectangular permanent magnetic chucks. Different versions and sizes available on request. Both with fine pole pitch for grinding and eroding work and with coarse pole pitch for milling.
  • Manually operated
  • Low magnetic field
  • No heat delay
  • Palletizable

MAGNETIC ROUND CHUCK

Permanent magnetic round chucks with reinforced ceramic magnetic system and Max pole pitch are used for clamping massive and heavy workpieces. The magnetic force is infinitely variable, and centering grooves machined into the surface make it easier to align the workpiece. Furthermore, a centering hole can be made in the surface if desired.

ELECTROMAGNETIC CHUCK PLATES

Different designs and sizes of electro-permanent magnetic chucks available on request. The magnetic clamping plates require only a short current pulse for switching and can be used autonomously. Without further energy consumption, without disturbing connections.

  • Force generation by current pulse
  • Force compound through one-time energy supply
  • No heat delay
  • Low residual magnetism
  • Extreme holding forces
  • Palletizable

PALLETIZING MAGNETIC CHUCKS

Automation has also become indispensable in mechanical processing. To keep machine downtimes as low as possible, palletizing and zero-point clamping systems are used on EDM, milling and grinding machines. This allows the user to clamp the workpiece already outside the machine, so that a stock of clamped workpieces can be created for the machining machine. External clamping takes place on pallets, which can be picked up in the machine with repeat accuracy. These pallets are then fed into the machine either manually or automatically. The described magnetic chucks are suitable for use with palletizing systems of all manufacturers.

For the production of self-supporting magnetic pallets, the reference elements can also be installed directly in the magnetic clamping plate. We also supply ready-made magnetic pallets equipped with original clamping and positioning element for all systems. For heavy machining and large workpieces, we recommend electro-permanent square pole technology, in combination with UniLock-R zero point clamping systems.

SINUSOIDAL TABLE

Sinusoidal tables are used to precisely machine angular surfaces on a wide variety of workpieces. With the help of end masses, any angle can be set according to the sine principle. Sine tables are mainly used in tool and fixture construction, where angular precision of 5 seconds is also frequently required.

We offer a wide range of standard equipment and are also happy to manufacture to your precision specifications.

Lamellenplatten

LAMELLA PLATES

Lamella support plates and beams, are used together with magnetic clamping plates. If parts are very difficult or impossible to clamp on a magnetic chuck due to very low material thickness, three-dimensional structure or poor magnetic properties, lamella chucks offer various additional options.

Pins can be inserted into lamellar plates and contours can be worked into them, or they can be used as bearing surfaces, e.g. for T-shaped parts. Lamella support plates are simply placed or screwed onto the magnetic clamping plate. Unless otherwise specified, our support plates are silver brazed and can therefore be mechanically processed in any way.

MAGNETIC CLAMPING BLOCKS

Permanent magnetic clamping blocks have 2 or 3 magnetic clamping surfaces which cannot be switched. They are used to clamp very fine parts or materials that are difficult to magnetize, such as high-alloy chrome steel or carbide. After machining, the block with the clamped workpiece can be completely removed from the machine for testing purposes. Clamping blocks are available in standard design and in reinforced design for heavy workpieces. Magnetic clamping blocks are mainly used for grinding, measuring and wire cutting.

Top quality magnetic clamping balls are used to hold parts in optimum working position during laser welding, polishing and assembly. Depending on the workpiece geometry and weight, swivel angles of up to 90° can be set.

REVERSING CONTROL UNIT

Electro magnetic chucks are operated on pole reversal control units. These devices make it possible to regulate the holding force and demagnetize workpieces. Pole reversal controllers can be supplied as panel-mounted or table-top units. Attention should be paid to the voltage and power of the solenoid. SPSG-TG pole reversal control units in table-top housing are optimal for retrofitting electromagnetic clamping plates with low installation effort. The device is simply plugged into 230V mains voltage, mains cable with Schuko plug and hand control lever are included.

POLE EXTENSIONS

Mobile and fixed pole extensions on the square pole clamping system allow clamping of wavy and warped metal parts. They adapt to your workpiece and hold it securely. The individual contact points between the magnetic chuck and the workpiece can be defined individually. It is also possible to drill through and machine inner edges on magnetically clamped workpieces. Additional pole extensions can be attached or interfering pole extensions removed in no time at all – so every workpiece has its own individual clamping device in no time at all.

For five-sided machining, the workpiece can be exposed with pole extensions. Complex structures of workpieces that are difficult to clamp can be incorporated into the magnetically active surface via pole plates. Our pole extensions are made of high-quality special steel and have the best magnetic flux properties – technically perfect and durable.

SHORT TAPER FLANGES

Rotary chuck short taper flanges for flanging round magnets on their spindle head. The flanges are finish machined on the machine side and face turned on the chuck side. They are made of soft steel. On request, we deliver our round chucks ready flanged.

For spindle heads with bayonet washer mounting according to DIN 55027 (formerly DIN 55022).
For spindle heads with camlock fastening according to DIN 55029 (formerly ASA B 5.9.D1)
