60 degree tungsten steel full tooth thread milling cutter machining center steel alloy milling cutter
1. Full-tooth design: The full-tooth spiral blade is continuously distributed along the axial direction, and multiple threads can be formed in one pass. Compared with single-tooth or three-tooth milling cutters, it is more efficient in the production of batch parts of the same specification. There is no need to lift the tool and feed multiple times, and one-cut forming can be achieved, effectively shortening the processing time and improving production efficiency.
2. High-precision processing: The edge grinding accuracy can reach ±0.002mm, the thread tolerance is stable at IT7 level, and the surface roughness Ra≤1.6μm,
3. Flexible processing: Not limited by the thread structure and direction, a thread milling cutter can process a variety of internal and external threads with different rotation directions. For some special structure threads, such as threads without transition threads or threads without back-cut grooves at the root, traditional processing methods are difficult to achieve, but tungsten steel full-tooth thread milling cutters can easily complete them.
In order to ensure a smooth machining process, the milling cutter has optimized chip removal and vibration resistance in structure. Its helix angle is carefully designed, usually between 35° - 45°, and with a large chip groove, it can quickly and smoothly discharge the chips, avoid chip accumulation in the machining area, and reduce the risk of tool damage. It is especially suitable for deep hole thread machining. At the same time, it adopts a short shank length ratio design (total length ≤ 5 times the shank diameter) and undergoes precision dynamic balancing (G2.5 level). The vibration amplitude is extremely small during high-speed cutting and can be controlled at <0.015mm, ensuring a stable machining process, and the surface quality of the machined thread is higher, without defects such as chatter marks.
