What are indexable milling cutters in precision parts processing

There are two series of indexable surface milling cutters in precision parts processing. Among them, the series with a back angle blade is suitable for continuous milling of steel and cast iron parts, with fast and labor-saving cutting, low power consumption, and low requirements for the process system. A set of blades has four cutting edges.

The series of blades without back angles is suitable for intermittent cutting of steel and cast iron parts. The cutting edge strength is high, and it is not easy to break when machining hard steel and materials with uneven materials. Using this type of milling cutter does not require high accuracy of the milling machine spindle, but it requires the machine to have sufficient power and good stiffness of the process system. A set of blades has 8 cutting edges, and the blade utilization rate is high. According to the size of the main deviation angle, there are mainly two forms: 75 ° and 90 °. According to the combination of the back front foot (which mainly affects the required cutting power) and the side front foot (which mainly affects the deformation and discharge direction of the chips), there are usually three forms.

Double negative rake angle type is suitable for rough milling and intermittent cutting; The double front corner type is suitable for processing aluminum alloys, copper alloys, plastics, composite materials, as well as semi precision machining of steel; The negative and positive front angle types have the advantages of the first two combinations, and are suitable for processing various carbon steel, alloy steel, tool steel, cast iron, and stainless steel in precision parts processing, with strong universality.
