9 CHOICE OF CUTTING INSERT When choosing an indexable insert, please also pay attention to its microgeometry, which is indicated by icons directly in the catalogue section. Below is an overview of the types of cutting edges you can find on our inserts. Overview of Cutting Edge Designs cutting edge face GAMO Sharp cutting edges – recommended for inserts designed for use with milling cutters for Al alloys. Sharp cutting F flank BETO wedges result in minimal deformation of the cut layer, reduced build-up on the edge and a lower cutting force ALO cutting wedge requirement. However, the strength of the cutting wedge is lower compared to other types. cutting edge face GAMO Rounded cutting edges – a slight rounding of the wedge with the aim of eliminating micro-imperfections on its surface. Rectifying the wedge at a certain very low radius (RE) improves the cutting edge's resistance to mechanical E flank ALO BETO cutting wedge damage, i.e. brittle fracture or so-called micro-crumbling. This modification is currently used on all indexable inserts R without a facet (F modification previously), which are used for milling almost all types of material. E cutting edge face BN facet gx GAMO Faceted cutting edges – a facet with width of x and angle of gx increases the angle gn of the cutting wedge in the T immediate vicinity of the cutting edge, thus also increasing its strength, i.e. its resistance to mechanical load, brittle flank BETO damage or fracture. Currently used only rarely, as it has been replaced by the S modification. ALO cutting wedge cutting edge BN facet face GB GAMO Rounded edges with facet – compared to the T modification, the insert has undergone rectification which S flank BETO cutting wedge results in rounding of the cutting edge and thickening by a facet. This modification increases the resistance of the wedge against mechanical damage to a greater degree. ALO RE R cutting edge facet 2 face 1 BN BN GB1 GB2 GAMO Edges with double facet – double facet with widths of x1 x2 and angle of gx1 gx2 further increases the strength of K flank the edge, i.e. its resistance to mechanical stress, brittle damage or fracture. Rarely used for milling inserts, only for BETO the most difficult cuts. ALO cutting wedge cutting edge facet 2 face 1 BN GB1 GB2 BN GAMO Rounded edges with double facet – compared to the K modification, the insert has undergone rectification P flank BETO cutting wedge which results in rounding of the cutting edge and thickening by a double facet. This modification provides the wedge with maximum resistance to mechanical damage. ALO R RE R 707 707
