Calculations of cutting conditions
Clamping elementmore +
Plain straight shank according to DIN 1835 A.
Tool geometrymore +
Helix angle = 30°. Rake angle = 6°.
Solid carbidemore +
Carbide materials are characterised by high compressive strength, high hardness and therefore high wear resistance, but also limited flexural strength and toughness.
Type Hmore +
Designed for milling (finishing) of materials of medium and higher strength (up to 1200 MPa). Surface roughness Ra 3,2; exceptionally even 1,6.
Feed direction possibility
Coating AlTiNmore +
Offers similar qualities as TiAlN, but even higher hardness. Substanial temperature stability. Designed for the most demanding applications. It provides excellent result mainly when combined with HSSE-PM steels (ASP 2030). The milling cutters manufactured from this steel are coated with AlTiN as standard.
