What are the main indexable milling tools for precision parts machining?

February 18, 2023

There are two series of indexable face mills for precision parts machining. Among them, the series of inserts with back angle is suitable for continuous milling of steel and cast iron parts, cutting lightly and effortlessly, consuming little power, requiring little process system, and a set of inserts with four cutting edges.

The series of inserts without back angle are suitable for interrupted cutting of steel and cast iron parts, with high cutting edge strength, and are not easy to chip when processing hard steel and materials with uneven material. Using this type of milling cutter, the accuracy of the milling machine spindle is not high, but requires sufficient power of the machine tool, good rigidity of the process system, a set of inserts with 8 cutting edges, high utilization of the inserts.

 

According to the size of the main deflection angle, there are mainly two forms of 75° and 90°. According to the combination of back front foot (mainly affects the required cutting power) and side front (mainly affects the deformation and direction of chip discharge), it is usually divided into three forms.
