Grinding

Magnetic chucks are efficient aids for  grinding small, thin, and larger workpieces. Their sophisticated design allows for cooling during grinding with coolant or by immersion in a dielectric solution. The main advantages of our magnetic chucks are their  compact clamping surface for clamping a wide range of workpieces,  long service life thanks to the grindable pole plate, and  easy maintenance and operation.

An interesting option is, for example, the  Neomicro permanent chuck  with exceptional clamping force, which combines high quality and a favorable price. For tilting workpieces in the longitudinal axis for precise angular grinding or EDM, you can equip the permanent chuck with a  Fixar sine table.

  • Permanent lammagblok_5_magnetickébloky.png Permanent magnetic blocks

    Permanent magnetic blocks

    Detailed description: These laminated blocks are made of a magnetically highly conductive material. They are composed of a combination of steel and brass laminations. For grinding, they are placed on the top pole plate of the magnetic chuck and after its activation, magnetic flux can enter freely into the workpiece. The blocks have a very stable construction, whereas individual laminations are not joined with bolts or screws. This allows modification of these laminated blocks according to individual customer requirements.
