1、 Structural characteristics
Blade shape: The blade of a double-edged ball end milling cutter resembles a ball head, which allows the tool to adapt more flexibly to various surface shapes during the milling process.
Cutting edge distribution: The cutting edges of some double-edged ball end milling cutters are divided into S-shaped cutting edges and arc-shaped cutting edges. There are multiple identical cutting edges on the same blade, and two cutting edges participate in cutting at the same time during milling.
Transposition design: Some double-edged ball end milling cutters adopt an transposition design. When the blade is blunt, the blade can be rotated by a certain angle (such as 180 °) to achieve the transposition of the blade, thereby improving the service life of the tool.
2、 Material and Coating
Material: Double edged ball end milling cutters are usually made of hard alloys (such as tungsten steel) or high-speed steel, which have high hardness and wear resistance, and can meet various milling processing needs.
Coating: In order to improve the wear resistance and service life of the cutting tool, some double-edged ball end milling cutters are coated with a special coating material on the surface, such as DLC (diamond-like carbon), etc.
3、 Usage performance
High feed rate: Double edged ball end milling cutters can achieve higher feed rates, thereby improving machining efficiency.
Long service life: In the processing of high hardness materials, double-edged ball end milling cutters can achieve a longer service life.
Stable machining state: When using a double-edged ball end milling cutter for machining, the cutting angle changes continuously, and the change in cutting force is also a continuous process, which helps to ensure the smoothness of the machining state and improve the smoothness of the machined surface.
Surface machining capability: The double-edged ball end milling cutter is an ideal tool for semi precision and precision machining of curved surfaces, capable of precision milling steep surfaces, small chamfers on straight walls, and irregular contour surfaces.
4、 Application scenarios
Double edged ball end milling cutters are widely used in mold manufacturing, aerospace, automotive manufacturing and other fields, for milling general iron materials such as mold steel, cast iron, carbon steel, alloy steel, tool steel, as well as various non-metallic materials.
5、 Precautions
Choose the appropriate tool specification: Based on the requirements of processing materials, processing accuracy, and processing efficiency, select the appropriate specification of the double-edged ball end milling cutter.
Reasonable use of coolant: Reasonable use of coolant during machining can help reduce cutting temperature and cutting force, and extend tool life.
Regularly check the wear of cutting tools: Regularly check the wear of double-edged ball end milling cutters and replace severely worn tools in a timely manner to ensure machining quality and efficiency.
In summary, the double-edged ball end milling cutter is a type of cutting tool with excellent performance and a wide range of application scenarios. During use, it is necessary to select appropriate tool specifications based on specific processing requirements, use coolant reasonably, and regularly check tool wear to ensure processing quality and efficiency.
