The programme comprises cutters with diameters from 2 to 20 mm, available in four- and five-flute geometries with a cutting edge length of 2x and 3xD.
The newly developed carbide grade TSTK introduced by Horn has is specifically intended for machining titanium, widely used in the aerospace and medical industries. As well as offering good tribological properties and high temperature resistance, the material transmits minimal heat into the substrate and acts as a kind of thermal shield.
Further important characteristics of the solid carbide end-mills are varying helix angles and pitches to ensure a softer, more gentle cut, therefore eliminating vibration and chatter. As titanium’s low thermal conductivity makes it difficult to remove heat from the point of cutting, a copious supply of coolant to the cutting edge is essential.
