What is indexable milling cutter in precision parts processing
There are two series of indexable milling cutters for precision parts processing. Among them, the series of blades with back corners are suitable for continuous milling of steel and iron castings. They are light and labor-saving, consume less power, and have low requirements on the process system. A group of blades has four cutting edges.
The series of blades without back angle are suitable for intermittent cutting of steel and iron castings. The cutting edge has high strength and is not easy to break when machining hard steel and uneven materials. With this type of milling cutter, the accuracy of the spindle of the milling machine is not required, but the machine tool is required to have sufficient power and the rigidity of the process system is good. A group of blades has 8 cutting edges, so the utilization rate of the blades is high. According to the size of the main deflection 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 chip deformation and discharge direction), there are usually three forms.
Double negative rake angle is suitable for rough milling and discontinuous cutting; Double positive front angle is suitable for processing aluminum alloy, copper alloy, plastic and composite materials, as well as semi finishing of steel; The negative and positive rake angles have the advantages of the first two combinations. They are suitable for processing all kinds of carbon steel, alloy steel, tool steel, cast iron and stainless steel in precision parts processing, with strong versatility.
