Whether while milling (rough and finish machining), drilling, sawing, welding or assembling, the EPM modules or module systems offer a large selection of clamping options, for example, to clamp during edge milling or deburring (without mechanical clamping equipment) or for the simple and quick fastening of workpieces during assembly. Workpieces can be easily and quickly fastened with the Doublemag magnet clamping elements. Through the use of pole extensions, any unevenness on the workpiece can be compensated for and a deformation of the workpiece can be prevented. Using pole extensions, plane-parallelism of up to 0.01 mm is possible on the workpiece. The processing runs without vibration and an even distribution of holding force is guaranteed throughout the entire ferrous clamping surface. Several Doublemags can be combined to process large parts. The Doublemag magnet modules have a solid steel surface and are therefore significantly more resistant than conventional plates with epoxy resin against hot chips, coolant and other processing influences.

In the event of a power failure or a cable break of the control line, the workpiece will remain clamped on the Doublemag modules with complete holding force. An accidental loosening of the workpieces through malfunction is also ruled out through the two-button operation both on the controller and on the cable remote control.

Ferrous on both sides
For processing big parts, several Doublemags can be connected with each other and controlled
Drastic reduction of set-up times
A 5-sided processing at simple and fast positioning of the workpiece
Low vibration while milling, and even distribution of holding force over the entire magnetic clamping surface
Using pole extensions, plane-parallelism of up to 0.01 mm is possible on the workpiece
Distortion-free holding of raw part or uneven workpiece, because positive-locking clamping by means of fixed and mobile pole extension
Underlining of workpieces no longer necessary
No damage to the magnetic clamping plate if there are breaks on the workpiece

The permanent magnet system is moved inside when it is switched on and off, e.g. by operating a lever. It consists of a pole plate and a magnet body. When switched off, the pole plate is not exactly congruent with the magnet body, which leads to a magnetic short circuit (Figure 1). When switched on, the pole plate is congruent with the magnet body and the magnetic circuit can only be closed via the workpiece (see Figure 2).

Features:

Permanent magnets work without electricity, are mobile and reliable.
The size and adhesive force of a magnet system are limited by the internal mechanical friction.
A permanent magnet can be demagnetized by strong external magnetic fields or a temperature of more than 80°C.

Minimizing setup times by quick and easy clamping
Increased tool life by low-vibration clamping
5-sided machining

All Assfalg electro-permanent magnetic chucks are equipped with a maximum of poles in the relationship to the size of the chuck.

If you review a price comparison, it is important for you, to analyze the clamping force of the chuck, because not the size of the chuck is important for the clamping force but the numbers of the poles are crucial for the clamping force of the magnetic chuck. It can mean that you will have bigger price differences by the same size of the magnetic chucks.

Do you have any questions? We will be happy to advise you individually.

You have already informed yourself about magnetic clamping, but for you are the advantages of the different Electropermanent Square Pole Chucks not yet understandable? Before you decide for a Electropermanent Magnetic Chuck, represented on the market, please ask you the following questions:

Which chuck is for your individual application advantageous?
Which special technical characteristics have the different electropermanent magnetic chucks?
Which material do you work?
Which thickness have your work pieces and how big are they?
How often is the processing of workpieces?

The electropermanent magnetic chuck from Assfalg Magnaslot is ideally suited for clamping of small and big work pieces for milling operations. Pole extensions, easily fixed on the surface of the magnetic chucks, guaranted a clamping without distortion even for uneven work pieces. The full steel body, patented and only available by Assfalg-magnets, offers an ideal protection against external influences like hot chips and coolant. If you work very big work pieces, you will get optionally a 4 channel controller, making a simultaneous switching of max. 4 magnetic chucks.
