Horn has launched a new, extensive range of solid carbide milling cutters designed specifically for machining titanium alloys such as Ti6Al4V. The programme comprises cutters with diameters from 2 mm to 20 mm, available in four and five flute geometries with a cutting edge length of 2 x D and 3 x D.
The newly developed grade TSTK that Horn has introduced 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 newly designed solid carbide end mills are alternative 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 directly to the cutting edge is essential.
