            Helix angle: The larger the helix angle of the end mill, the longer the contact line between the workpiece and the blade will be applied to the blade of the unit length, which will help to extend the tool life. On the other hand, the helix angle is increased, and the axial direction component of the cutting resistance is also increased, so that the tool is easily detached from the shank. Therefore, when the tool is processed with a large helix angle, the shank rigidity is required to be good. The 0° helix angle is called a straight edge and its contact line is short.

            Selection of helix angle: Stainless steel is a difficult-to-cut material with low thermal conductivity, which has a great influence on the tool tip. The use of a large helix angle end mill can extend the tool life. As the hardness of the high hardness material increases, the cutting resistance increases, and an end mill with a large helix angle should be used. For the case where the rigidity of the workpiece such as thin plate processing is low, an end mill with a small helix angle is preferably used.

        

            Core thickness

            The core thickness is an important factor in determining the rigidity of the end mill and the chip pocket. The core thickness of the integral end mill is generally 60% of the outer diameter. The core thickness is increased, the cross-sectional area is increased, the rigidity is increased, but the chip flute is reduced, and the chip discharging performance is deteriorated; conversely, the core thickness is reduced in rigidity, but the chip discharging performance is enhanced.

        

            Previously used high-speed steel integral end mills, and now with the advancement of coating technology and tool material technology, coated hard alloy integral end mills and indexable end mills are becoming more and more popular, widely used in mold processing, High hardness material processing and other fields.

        

            The main cutting edge of the end mill is on the cylindrical surface, and the cutting edge on the end face is the minor cutting edge. It is not possible to make a feed motion along the axial direction of the milling cutter during operation. End mills can be used in the machining of side machining, groove machining, and surface machining. There are also a wide variety of end mills that can be used for various machining modes.

        

            End mill advantages:

            1. Using the new interpolation cutting edge, the efficiency of spiral interpolation milling or slope milling is improved;

            2, due to the double spiral groove and the unequal distance design, HPC milling has higher efficiency;

            3. Ideal for high dynamic HDC milling;

            4. Process stability, automation and repeatability through optimized chip flute type and wear resistance;

            5. Highly versatile in various materials and processing strategies;

            6. ToolExpert, ToolExpert HDC, ToolExpert HelixRamp application after FRAISA cutting and machining parameter verification;

            7. New choices for opening and cycloid machining;

            8. Develop more applications through short-handled tools;
