The NACHI Hyper AP1 Hob is a high-performance gear hob under NACHI's cutting tool series, which is well-suited for precision gear machining scenarios relying on its advanced design and reliable performance. It inherits NACHI's consistent advantages in material research and cutting tool technology, and here is a detailed overview combining the brand's gear cutter characteristics and relevant industry application information:
Wide Speed Range Adaptation: This hob supports both dry and wet machining methods, with strong adaptability to processing environments and no strict restrictions on workpiece materials. It can stably exert its performance at a common machining speed of 60 - 160m/min, which can meet the efficiency requirements of both general - purpose processing and large - batch production lines.
Precision Gear Shaping: As a professional gear hobbing cutter, it adopts a helical tooth structure design referring to high-precision gear hob standards. During the machining process, it can achieve synchronous rotating motion with the gear blank, and gradually form a standard involute tooth profile. It is suitable for machining common gear types such as spur gears and helical gears, and can meet the precision needs of industrial transmission components.
Excellent Re-grinding Performance: A notable feature of this hob is that its cutting surface can maintain excellent cutting performance without re-coating after re-grinding. This not only reduces the subsequent maintenance costs of the tool but also shortens the downtime caused by tool maintenance, improving the overall production continuity.
NACHI has a complete independent industrial chain from special steel materials to surface coating technology for its cutting tools. It is speculated that the Hyper AP1 Hob may adopt high-quality high-speed steel or cemented carbide as the base material. The base material, together with advanced surface treatment technology similar to the brand's Hyper series tools, can enhance the tool's wear resistance and impact resistance. For example, some of NACHI's Hyper series tools achieve more than twice the service life of traditional tools by combining surface modification technology with special nitriding treatment. This design enables the Hyper AP1 Hob to cope with the cutting of hard steels and other difficult-to-machine materials, and avoid problems such as edge chipping during heavy cutting.
Wide Industry Application: It is widely used in gear machining in key industries such as automotive, petrochemical, and power plants. It can be used to process transmission gears, reducers gears, and other core components. These components have high requirements for gear accuracy and service life, and the Hyper AP1 Hob can ensure the stability of product quality in mass production.
Cost-Saving for Enterprises: On one hand, its long service life reduces the frequency of tool replacement; on the other hand, the no-coating requirement after re-grinding simplifies the tool maintenance process. For enterprises, these advantages directly reduce the comprehensive costs including tool procurement and production downtime, which is in line with the cost-control needs of industrial mass production.
Referring to NACHI's complete gear cutter product line layout, the Hyper AP1 Hob is likely to have multiple specification models to match different gear parameters such as module and pressure angle. It can be adapted to various types of hobbing machines and can cope with the processing needs of gears of different sizes and specifications. Whether it is the production of small precision gears in the automotive field or the processing of large-module gears in general industrial machinery, it can provide targeted cutting solutions.
| Parameter Type | Typical Specification | English Description |
|---|---|---|
| Cutter Material | GRAN MET SF, MACH 7, MACH 11 | Self-developed high-performance materials by NACHI, featuring excellent hot-hardness and wear resistance, which can significantly reduce crater wear and extend tool life. |
| Coating Type | Super Dry Ⅲ | The optimized coating structure enhances bonding force with the base material. Its oxidation temperature reaches 1,300°C, enabling high-speed dry cutting and reducing tool flank wear by 40%. |
| Common Outer Diameter | 75 mm, 90 mm | 75 mm is a typical specification for medium and small module gears, while 90 mm is suitable for mainstream medium module gear processing, matching most conventional hobbing machines. |
| Number of Starts | 3 starts, 4 starts | 3 starts is a common configuration, which balances machining efficiency and tooth profile accuracy; different starts can be selected according to batch production needs and precision requirements. |
| Number of Gashes | 14, 16 | 14-gash and 16-gash are mainstream specifications. They can evenly distribute cutting force during machining, optimize chip removal effect, and avoid chip accumulation affecting tooth surface smoothness. |
| Maximum Cutting Speed | Up to 400 m/min | It can achieve high-efficiency machining equivalent to carbide hobs. Even at a cutting speed of 300 m/min or more, stable cutting performance can be maintained. |
| Typical Axial Feed | 1.7 mm/rev, 2.4 mm/rev | The feed rate is configurable according to workpiece material and hardness. For example, an axial feed of 2.4 mm/rev is applicable for processing 18CrMo4 workpieces. |
| Applicable Gear Module | Module 2.25 (Typical) | Widely adapted to gears with different module specifications. The module 2.25 configuration is commonly used in industrial transmission components such as 15CrMo4 and 18CrMo4 gears. |
| Applicable Workpiece Hardness | 180 HB (Typical) | Stably processes low-carbon alloy steel workpieces such as 15CrMo4 and 18CrMo4 with a hardness of 180 HB. It also supports machining of hardened gears after customization. |
| Applicable Pressure Angle | 17.5° (Typical) | Matches the pressure angle of mainstream industrial gears, ensuring the consistency of the tooth profile of the processed gears with the design standards. |
