What Is CNC Hobbing?

Зубофрезерная обработка с ЧПУ is a specialized subtractive manufacturing process designed exclusively for producing gears—one of the most critical components in mechanical transmission systems. Unlike manual gear cutting (which relies on operator skill and is prone to inconsistency), it uses Технология ЧПУ (Компьютерное числовое управление) to automate the movement of a cutting tool called ahob.”​

По своей сути, а Hobbing Process works by rotating both the hob (a cylindrical tool with helical cutting teeth) and the workpiece (the gear blank) in a synchronized manner. As the hob feeds into the blank, its teeth progressively cut the gear’s teeth profile—whether it’s straight, helical, or worm gears. This synchronization ensures each tooth has identical spacing, форма, and depth—key for smooth gear operation.​

Суммируя, Gear Hobbing (powered by CNC) is the gold standard for high-volume, high-precision gear production. It eliminates human error, ensures consistency across batches, and delivers gears that fit and function seamlessly in everything from small motors to heavy industrial machinery.

The CNC Hobbing Process: Шаг за шагом

Наш Процесс с ЧПУ следует структурированному, quality-focused workflow to ensure every gear meets your exact specifications. Each step is automated but monitored by our gear engineers to catch inconsistencies early:​

  1. Дизайн & Программирование: Convert your gear’s CAD model (or technical drawing) into a CNC-compatible program. Our team optimizes the hob path, скорость, and feed rate to minimize material waste and maximize tooth precision—critical for gear performance.​
  1. Workpiece Preparation: Clean the gear blank (сырье) and secure it in a CNC chuck or fixture. We pre-measure the blank’s diameter, толщина, and hardness to confirm it meets production requirements.​
  1. Hob Setup: Select the appropriate hob (материал: high-speed steel for soft metals, carbide for hard alloys) based on the gear’s material and tooth profile. The hob is mounted on the machine’s spindle and calibrated for correct alignment.​
  1. Gear Cutting Process: Машина ЧПУ выполняет программу: the hob and gear blank rotate in synchronized motion, while the hob feeds axially into the blank. This step cuts the gear’s teeth to the exact depth and profile specified.​

Выслушивание & Осмотр: Remove any sharp edges (нормы) from the gear’s teeth using automated deburring tools. We then inspect the gear using a gear measuring machine (GMM) to verify tooth profile, подача, and backlash. If it meets standards, it moves to Gear Surface Treatment (При необходимости).

Поверхностная обработка: Enhancing Gear Performance

After hobbing, Поверхностная обработка is critical for improving a gear’s durability, износостойкость, and lifespan—especially for gears that operate under high load or in harsh environments. We offer five core Методы лечения, tailored to your gear’s application:​

Поверхностная обработкаЦельProcess Details​Отраслевой вариант использования
Карбинизирует & ГашениеHardens the gear’s surface (сохраняя затруднение) to resist wear​Heat gear to 900–950°C in carbon-rich atmosphere; утолить в масле; temper to reduce brittleness​Автомобильная трансмиссионная шестерня, industrial gearboxes​
Твердый хромовый покрытиеДобавляет тяжело, коррозионный устойчивый слой (5–50 μm thick)​Electroplate chromium onto the gear’s surface; polish for smoothness​Gears in wet environments (НАПРИМЕР., морской пехотинец, Продовольственная обработка)​
ВыстрелилIncreases fatigue resistance by creating compressive stress on the surface​Blast gear with small steel/ceramic shots (0.2–1.0mm) at high pressure​Aerospace gears, high-performance racing transmission gears​
ФосфалированиеCreates a porous, oil-retaining layer to reduce friction​Immerse gear in phosphoric acid solution; rinse and dry​Small electric motor gears, household appliance gears​

Each treatment is tested to ensure it meets Качество поверхности standards—we verify hardness, Толщина покрытия, and finish before delivering the final product.

Допуски: How We Control Gear Precision

Gear Tolerances are the allowable deviations from a gear’s designed dimensions (НАПРИМЕР., tooth profile, подача, backlash). Для передач, tight tolerances are non-negotiable—even small deviations can cause noise, вибрация, or premature failure in transmission systems.​

Наш Контроль толерантности system uses three layers of precision to meet even the strictest industry standards (ISO/AGMA):​

  1. Pre-Machining Calibration: We calibrate our CNC hobbing machines daily using certified master gears (точность: Iso 3) to ensure hob alignment and synchronization are precise.​
  1. Текущий мониторинг: Sensors on the machine measure tooth pitch and depth in real time, adjusting hob speed or feed rate if deviations occur.​
  1. Post-Machining Inspection: Our quality team uses a gear measuring machine (GMM) to scan every gear’s tooth profile, pitch circle diameter, and backlash. We reject any gear that falls outside your specified Уровни толерантности.​

Below are our standard Gear Tolerances for common applications:​

Application​Profile Tolerance (Iso)​Pitch Error​Backlash​Шероховатость поверхности (Раствор)​
General Industrial​Iso 7 (AGMA 8)​± 0,01 мм0.05–0,1 мм1.6–3,2 мкм​
АвтомобильIso 6 (AGMA 9)​±0.007mm​0.03–0.08mm​0.8–1.6 μm​
Aerospace/Medical​Iso 5 (AGMA 10)​± 0,005 мм0.01–0.05mm​0.4–0,8 мкм​

Advantages of CNC Hobbing: Why It’s Better Than Other Gear Cutting Methods

Compared to alternative gear cutting processes (НАПРИМЕР., gear shaping, фрезерование), Зубофрезерная обработка с ЧПУ offers unique benefits that save time, сократить расходы, and improve gear quality. Вот вершина Advantages of CNC Hobbing:​

  • Точные преимущества: CNC synchronization ensures every tooth on a gear (and every gear in a batch) has identical profile and spacing. This eliminatestooth-to-tooth variation—a common issue with manual methods that causes gear noise and wear. For high-precision applications (НАПРИМЕР., аэрокосмическая), this is non-negotiable.​
  • Стоимость преимущества: CNC hobbing is faster than most other gear cutting processes—one machine can produce up to 500 small gears per shift. It also uses fewer tools (a single hob can cut multiple gears) and generates less waste, cutting production costs by 20–30% for high-volume runs.​
  • Quality Advantages: The hobbing process creates a smooth, consistent tooth surface finish (RA 0,8-3,2 мкм) that requires minimal secondary finishing. This reduces lead times and ensures gears operate quietly and efficiently.​

Гибкость: CNC programs are easy to modify—we can switch between Gear Types (НАПРИМЕР., straight to helical) in under 30 минуты (no need for new fixtures). This is perfect for small-batch projects or rapid prototyping.

Методы производства: Optimizing Gear Production

To get the most from CNC hobbing, Мы используем специализированные Методы производства that balance speed, точность, и стоимость. Here are three key methods we employ:​

  • High-Speed Hobbing: Для мягких материалов (НАПРИМЕР., алюминий, низкоуглеродистая сталь), we use carbide hobs and increase spindle speed (до 4,000 Rpm). This reduces cycle time by 40% while maintaining tooth precision—ideal for high-volume consumer electronics gears.​
  • Dry Hobbing: For materials that don’t generate excessive heat (НАПРИМЕР., латунь, powder metals), we skip cutting fluids. This reduces environmental impact, lowers disposal costs, and eliminates the need for post-machining cleaning—cutting production time by 15%.​
  • Profile Optimization: For high-load gears (НАПРИМЕР., Промышленные коробки передач), Мы используем “зубной коронал”—a technique that slightly modifies the tooth profile to distribute load evenly across the tooth face. This increases gear lifespan by 50% or more and reduces the risk of premature failure.​

Эти Hobbing Techniques are backed by decades of gear manufacturing experience—we don’t just follow industry best practices; we help define them.
