Design details engineered for accuracy, tool life and process stability.
Strictly adheres to the ANSI/ASME B1.5-1997 standard and meets the lead screw connection requirements of heavy-duty transmission equipment; threads are formed in a single pass, boosting machining efficiency by 35% compared to traditional taps.
Thread pitch accuracy is maintained within ±0.005 mm, the thread profile angle tolerance is ≤0.02°, and surface finish reaches Ra ≤0.2 μm, satisfying the rigorous tolerance and transmission accuracy requirements for drive lead screws.
Utilizes HRC68-grade ultrafine-grained cemented carbide with 60% higher resistance to edge chipping, enabling stable machining of heavy-duty transmission materials such as steel and stainless steel.
The edge radius is precisely controlled at 0.003 mm, balancing sharpness with wear resistance, minimizing edge chipping, and ensuring machining consistency.
Utilizing a vacuum ion plating process, coating adhesion is increased by 40%, preventing coating detachment that could compromise machining accuracy.
The direct action of the cutting fluid reduces friction between the cutting edge and the workpiece, improves the quality of the machined surface, and reduces tap wear.
The cutting edge radius is precisely controlled at 0.003 mm, balancing sharpness and wear resistance, reducing edge chipping, and ensuring machining consistency.
Featuring an eccentric cutting design, it eliminates the need for pre-drilling a center hole and allows for the direct machining of blind-hole threads, thereby reducing process steps and increasing efficiency.
