Magnets and magnet systems
Permanent magnetic chucks with fine transverse pole spacing for grinding processes
The chucks are designed specifiically for the machining of workpieces of less than 5 mm thickness and 15 mm diameter or 15 mm square section.
Optimum holding facility for large workpieces is similarly possible.
A powerful permanent ceramic magnet system, a close pole step and the small overall height makes ist usable for a large numer of tasks.
The design of the cast iron basic section and the hardsoldered top plate, as well as a ceramic magnet system, ensure an extremely long and maintenance-free life.
The magnet systems can also be used to spark erosion machines.
Curve of lines of force: approx. 8 mm above the pole plate, consequently no magnetisation of the tools
Pole spacing: Steel 6 mm / Brass 1,5 mm / Steel 2 mm / Brass 1,5 mm
Holding power: max. 80 - 100 N/cm² (≙ 8 - 10 kg/cm²)

The shaft does not project from the chuck and can be handled using an Allen key.
Further dimensions on request.
Machining of the upper plate possible without impairing the holding power (steel 15 mm / non-ferrous 7 mm). Attachment of the chucks to the machining table by means of clamping lugs. The chucks are supplied with 2 stops as standard.
Safety switch for permanent magnetic chucks for processing machine
If necessary, some of the magnetic chucks can be fitted with an additional safety switch. There is a reference to the safety switch on the pages of the corresponding models.
This proximity switch monitors the "on/off" state of the magnetic chucks and ensured that the commissioning of the machine is possible only when the chucks switched on. When a power failure or power cut off during machining, the workpiece remains tense due to the permanent holding force.
