Corner, face and plunge milling

This enables greater axial cutting depths in the process. Horn relies on a six-edged indexable insert. The insert can be used on both sides and has three axial and three radial cutting edges on each side. A large core cross-section with maximum cutting edge length is the impressive feature of the trigonal precision-sintered insert. Despite the negative insertion angle, the cutting edge design results in a positive cutting geometry, which leads to an easy cut. The six cutting edges per insert result in a good ratio of costs per cutting edge.

The DA65 system can be used as a roughing and finishing system. In the tests carried out, the milling system achieved finishing surfaces that meet the usual market requirements. Due to the choice of axial and radial angles, a lower torsional moment and a lower transverse load on the spindle compared to previous systems have been demonstrated. This means that the system can also be used on less powerful machines with unstable ambient conditions. Another advantage of the selected axial angle is the good chip removal, especially in helical plunging operations.

The cutting edge shape generates an exact 90° corner angle with a maximum cutting depth of 7 mm. The patented indexable inserts are available with corner radii of 0.8 mm and 1.2 mm. The proven carbide substrate SA4B is used. This substrate is suitable as an all-rounder for milling steel, stainless steel, cast iron and aluminum. The inserts are also available in grades SC6A and IG6B for use in other material groups.

The basic bodies are available as end mills in diameters of 32 mm and 40 mm. In these variants, the milling tools are equipped with two and three cutting inserts. As shell cutters, the tools are available in cutting circles of 50 mm, 63 mm, 80 mm and 100 mm. Depending on the diameter, the number of teeth is four, five, seven, nine and eleven. All basic bodies have targeted internal cooling at the cutting point. The DA65 milling system guarantees process reliability for a wide range of applications, high performance and economic benefits for the user.
