MAGNET Clamping technique function

The advanced QX technology comes up with many intelligent improvements, both mechanically and magnetically. Due to the use of connected block-pole-fields in the monolithic frame construction of the magnet clamping plate, the stiffness has been significantly increased compared to the old single-pole-technology - even with its small construction height. Also the epoxy-resin-interfaces have been reduced and the magnetic retention forces as well as the air gap behavior have been improved with the revolutionary block-field-technology. The threads in the soft magnet poles are provided with wear-resistant tool steel inserts.

   

The QX magnet clamping technology is available for plates in different heights and for clamping blocks. Two different pole sizes can be selected. Depending on the expected work piece geometry two pole sizes, 50 x 50mm or 70 x 70mm, can be chosen.

Poles with the size of 50 x 50mm generate a magnetic field which enters 12mm into the work piece. That makes them a perfect choice for thinner and smaller work pieces. Another advantage is that especially smaller work pieces occupy more pole transitions which ensures a more evenly clamping process. Compared to the 70 x 70mm pole, a poorer air gap behavior and a higher set-up effort (more pole extensions) must be mentioned as a disadvantage. The nominal retention force is super strong with 160N/cm2 = 4 kN per pole. 

Pole with the size of 70 x 70mm generate a magnetic field which enters 18mm into the work piece. That makes them a perfect choice for larger work pieces. The excellent air gap behavior allows to clamp also uneven work pieces safely. On the 70 poles, pole extensions with a  higher hub (height adjustment) can be used. The nominal retention force is super strong with 160N/cm2 = 7.8 kN per pole.
