Precision Straight Bevel Gear Generator Milling Machine

High Efficiency and Low-Noise Gear Processing Solution - Straight Bevel Gear Milling Machine

In recent years, as manufacturing industries demand higher precision, lower noise, and greater productivity in gear transmission, traditional gear planing machines can no longer meet modern production needs. This is why the Straight Bevel Gear Milling Machine has become a focus of attention among customers.

Over the past five months, our engineering team has been in close communication with a client who had very clear machining requirements. After evaluating the gear drawings and processing parameters, our engineers recommended a suitable milling machine solution. Eventually, the customer placed an order. Today, we will take a closer look at this powerful and efficient Straight Bevel Gear Milling Machine.

1. Market Demand and Application

Straight bevel gears are widely used in transmission systems such as gearboxes, reducers, and automotive rear axles. These components require not only high precision but also smooth meshing and low operating noise. Traditional gear planing machines, although accurate, are inefficient, noisy, and prone to tool wear. In contrast, the Straight Bevel Gear Milling Machine provides an advanced, high efficiency alternative.

With its double-cutter head structure, rigid machine body, and intelligent CNC system, the milling machine ensures high efficiency and low-noise gear cutting. It is ideal for machining bevel gears with crowned tooth forms, both in rough and finish cutting processes. Whether for industrial gearboxes or precision gears in luxury cars, this Straight Bevel Gear Milling Machine delivers exceptional results.

2. Balancing Efficiency and Precision

Compared with hobbing or spline rolling machines, the Straight Bevel Gear Milling Machine may not reach the same production speed, but it is 3-5 times more efficient than traditional gear planing machines. This makes it a highly productive choice for medium and large batch manufacturing.

The double cutter head system allows simultaneous rough and finish cutting in one setup, minimizing workpiece repositioning errors and auxiliary time.

The machine achieves a gear accuracy level of up to GB 6, ensuring consistent quality for precision transmission components. For manufacturers pursuing high precision and stable gear performance, this milling machine represents an ideal balance between accuracy, efficiency, and reliability.

3. Structural Design and Control System

The Straight Bevel Gear Milling Machine adopts the German SIEMENS 828D CNC control system, achieving four axis control and three axis linkage. The spindle servo motor provides stepless speed regulation and supports manual electronic handwheel adjustment for tool setting and fine tuning, offering both flexibility and convenience for operators.

The dual-cutter head structure features a unique design that maintains excellent rigidity while optimizing the available working space. Both the cradle and the workpiece box adopt high precision worm gear drives, ensuring smooth rotation, strong rigidity, and high positional accuracy during machining.

All critical components-such as the CNC system, bearings, electrical units, and seals-are imported from leading international brands to ensure reliability and long-term stability.

The milling machine is equipped with a fully enclosed electrical cabinet featuring a temperature control system to maintain stable performance even in fluctuating workshop environments.

4. Safety, Stability, and Ease of Use

The Straight Bevel Gear Milling Machine is also designed with operator safety and production cleanliness in mind. It comes with a fully enclosed safety guard and an automatic chip conveyor, preventing chips from scattering and keeping the working environment clean.

The cooling system features a high-speed coolant pump (0.25 kW, 2800 rpm), ensuring continuous coolant circulation and maintaining stable cutting temperature. This design improves tool life and guarantees a fine surface finish.

The machine's main motor has a power of 3.7 kW, with a speed range of 800-1500 rpm, suitable for a wide range of cutting conditions. The total power consumption is 20 KVA. Each tooth can be processed within 4 to 69 seconds, offering a perfect balance between productivity and precision.

5. Wide Application Range

The Straight Bevel Gear Milling Machine is highly versatile across multiple industries.

In automotive manufacturing, it is used for machining rear axle gears, differential gears, and half-shaft gears.

In industrial machinery, it is applied to gearbox and reducer gears that require high strength and accuracy.

In aerospace, agricultural machinery, and construction equipment, it provides reliable processing of straight bevel gears for heavy-duty applications.

Many customers have validated the milling machine's advantages in real world production: fast cutting, low noise, stable accuracy, and long term reliability. These benefits not only enhance production efficiency but also significantly reduce cost and rework rates.
