Hard milling, EDM.ing, Grinding

Hard machining completes the process chain


Hard steel up to HRC 64 is being machined on our high speed CNC Machining centres. There is an increase of tool manufacturers that are discovering the advantages of hydrostatic milling on a KERN Pyramid Nano. Geometric contours or extreme hard steels that can not be manufactured via milling can be manufactured with the EDM process or by grinding. To round off our technology we offer, grinding, wire cutting, die sinking, jig grinding, surface grinding and polish grinding.
One of our core competences, the design and manufacturing of axis components, spindle beds and guiding bearings, derives from our own fabrication of KERN machine components.
Thus the most accurate bearing surfaces are required for guideways. Grinding and polishing guarantee the necessary flatness and parallelism with a superb surface finish.   

  • Wire cutting (EDM)

    Our new Agiecut Vertex 3F allows tolerances of up to 1,5µm on the work piece.
    Surface quality up to Ra 0.05
    Wire diameter from 0.03mm to allow internal radii of 20µm.
    A Axis (CNC Dividing Head) operations are also possible with our wire cutting machine.
