The excellent performance of alloy milling cutters comes from the high-quality and ultra-fine grained carbide matrix, which provides a perfect combination of tool wear resistance and cutting edge strength. Strict and scientific geometry control makes the cutting and chip removal of the tool more stable. During cavity milling, the necking structure and short edge design not only ensure the rigidity of the tool, but also avoid the risk of interference. The application of alloy milling cutters will be expanded as the technology continues to be refined.
Carbide insert manufacturers briefly talk about the common types of milling cutters that can be summarized as follows:
1. Face milling cutter, the main cutting edge of the face milling cutter is distributed on the cylindrical surface of the milling cutter or the electrical cone surface of the circular machine tool, and the secondary cutting edge is distributed on the end surface of the milling cutter. According to the structure, face milling cutters can be divided into integral face milling cutters, carbide integral welding face milling cutters, carbide machine clamp welding face milling cutters, carbide indexable face milling cutters, etc.
2. Keyway milling cutter. When processing the keyway, first feed a small amount along the axial direction of the milling cutter each time, and then feed along the radial direction. Repeat this many times, that is, the machine tool electrical appliance can complete the processing of the keyway. Since the wear of the milling cutter is on the end face and the cylindrical part close to the end face, only the cutting edge of the end face is ground during grinding. In this way, the diameter of the milling cutter can remain unchanged, resulting in higher keyway processing accuracy and longer milling cutter life. The diameter range of keyway milling cutters is 2-63mm, and the shank has straight shank and Mohr-style tapered shank.
3. End mills, corrugated edge end mills. The difference between a corrugated edge end mill and an ordinary end mill is that its cutting edge is corrugated. The use of this kind of end mill can effectively reduce cutting resistance, prevent vibration during milling, and significantly improve milling efficiency. It can change long and narrow thin chips into thick and short chips, allowing smooth chip discharge. Since the cutting edge is corrugated, the length of the cutting edge that contacts the workpiece is shorter, and the tool is less likely to vibrate.
4. Angle milling cutter. Angle milling cutter is mainly used on horizontal milling machines to process various angle grooves, bevels, etc. The material of angle milling cutter is generally high speed steel. Angle machine tool electrical milling cutters can be divided into three types: single-angle milling cutters, asymmetric double-angle milling cutters and symmetric double-angle milling cutters according to their different shapes. The teeth of angle milling cutters are less strong. When milling, the appropriate cutting amount should be selected to prevent vibration and edge chipping.
Alloy milling cutters have high hardness, high wear resistance, high red hardness, high thermal stability and oxidation resistance. Suitable for various high-speed cutting tools, various wear-resistant parts working at high temperatures, such as hot wire drawing dies, etc. YT5 tools are suitable for rough machining of steel, YT15 is suitable for finishing steel, and YT is suitable for semi-finishing steel.
