MAPAL introduces the OptiMill-3D high-performance solid carbide milling cutters. Along with extremely heat-resistant coatings and special carbide substrates, these tools are characterised in particular by the dimensions and geometries specifically adapted to mould making. Two new high-feed milling cutters for hard machining are suitable for milling hardened parts with a hardness of 45-66 HRC, and are developed a special face geometry.

The milling cutter with four cutting edges is used above all for roughing as well as for pre-finishing. Due to the fewer number of cutting edges and the related more generous dimensioning of the chip flutes, reliable removal of the chips is ensured. This milling cutter is also the tool of choice for machining with long projection lengths and in deep cavities.

The milling cutter with six cutting edges can be used optimally for roughing and pre-finishing, as well as for finishing flat surfaces with a high feed rate. It produces the best surface finishes and flatness. The equivalent, the OptiMill-3D-HF, with three and four cutting edges is available for soft machining. The dimensions here are matched to the OptiMill-3D-HF-Hardened.

The corner radius milling cutter OptiMill-3D-CR-Hardened is used for finishing 3D moulds up to a hardness of 66 HRC. It produces very good, smooth, high-gloss surface finishes with maximum feed rate. Crucial here are the highly accurately manufactured corner radii. The OptiMill-3D-CR-Hardened is available in the diameter range 4 to 12 mm with different lengths and corner radii.

The new circular radius milling cutters OptiMill-3D-CS are predominantly used in mould making in deep cavities, for complex free-form shapes as well as for the manufacture of turbine blades and impellers. The special feature of the tools is the optimal geometric combination of radius and form cutter that makes a larger path spacing during pre-finishing and finishing possible.
