03-14-2012 - Users who have to reach high accuracies during surface grinding can now sharply increase their productivity. Compared to conventional parallel pole technology, the MAGNOS square pole grinding plates from SCHUNK, the competence leader for clamping technology and gripping systems, can achieve an increase in productivity up to 200%. This is due to the use of moveable pole extensions which ensure a homogenous, deformation-free clamping. They are used for grinding flat workpieces, unevenness is compensated, parallelism is ensured, and therefore micron precise grinding operations can be carried out at the first go.

With the MAGNOS square pole technology, multiple grinding operations, repeated retrofitting, and time-consuming support of the workpiece is no longer necessary. If large plates of measuring tables measuring 60 x 355 x 44 mm, made of tool steel 1.2842 (58+4 HRC) are ground, the operation time during surface and parallel grinding can be reduced by 66%. Such effects help to amortize the higher investment costs of the square pole technology in a very short period of time.

In order to be able to adjust the adhesion effect of the magnetic chucks to the individual workpieces, its standard version is equipped with a holding force control. A special attachment to the magnetic chuck even allows machining of very hard workpieces, which can then be easily removed from the magnetic chuck again. MAGNOS square pole grinding plates with pole extensions particularly pay off for surface grinding of large, thin work-pieces with a minimum material thickness of 4 mm. Due to the grid dimensions 32 x 32 mm, small and narrow parts can be also clamped free of deformation. If needed, the square pole plates can be added to existing parallel pole plates for new clamping tasks. Its monoblock design provides a high rigidity and stability, and in turn vibrations are mini- mized, and the surface quality is improved. For a fast adjustment of the workpieces, additional stops can be mounted into the lateral tapped holes. The square pole grinding plates of the innovative family-owned company are available in twelve standardized sizes, and adjustments to individual customer dimensions are possible.
