Milling system with patented tangentially screwed indexable
The patented HORN tangential milling system has been
extended to include another milling range. The new 406 milling
system - featuring a four-edged rhombic indexable insert - is
designed as an end-milling range for smaller cutting edge
diameters. The milling shanks with DIN 1835-B holders are
available with cutting edge diameters of 16, 20, 25, 32 and 40
mm, and come equipped with two to six 406-type cutting inserts.
The precision-ground rhombic indexable inserts achieve a high
level of precision with very good surface quality levels. Positive
cutting and axial angles enable a soft cut. The secondary cutting
edge with integrated trailing chamfer produces outstanding face
surfaces. An additional free-formed surface chamfer provides
a stable wedge angle and a very smooth milling process.
The indexable inserts in carbide grade AS4B, a tough basic
substrate, are coated with TiAlN.
"Projections" attached to the cutting inserts also produce an
improved relief angle for the individual secondary cutters and,
furthermore, provide extra protection on the flat side for the
main cutting edge, which is set back in this case. The cutting
inserts with a corner radius of 0.4 mm achieve cutting depths of
up to 6.3 mm and are suitable for milling exact 90° shoulders.
The entire cutting length can be used during this proces
