Title:
A front fraise and its use
Document Type and Number:
Japanese Patent JP6025569
Kind Code:
B2
Abstract:
The face miller is equipped with a plurality of plate-shaped hard material cutting inserts that are distributed over the circumference. The hard material cutting inserts are located on a graduated circle in pockets of a blade carrier and have a main cutting edge, which is adjusted at a cutting edge angle smaller than 90° relative to the working plane of the miller. In order to ensure maximum machining performance at a good service life, the cutting edge angle is selected to range between 10° and 30°, wherein the main cutting edge at the same time has a slightly convex design. The main cutting edge transitions into the secondary cutting edge via a transition radius having a value that ranges between 0.5 and 1.5 mm. The axial rake angle ranges between 20 and 30°. According to an advantageous further development, the radial rake angle ranges between −6° and −10°.
