Cradle 5-axis Machining Center Applications

Yangsen cradle-style five-axis machining centers are designed for industries that require high precision, complex geometry machining, and multi-surface processing in a single setup. With high-rigidity structural designs, high-speed direct-drive rotary tables, and motorized high-performance spindles, these machines process challenging components efficiently and with exceptional accuracy.

Our five-axis solutions are widely used in aerospace, robotics, automotive power systems, high-precision molds, automation equipment, and UAV manufacturing, where stability, repeatability, and simultaneous multi-axis motion control are critical.

Aerospace & Aviation Components

Our machines are widely applied in the production of blisks, turbine blades, impellers, and complex structural parts used in aircraft and UAV platforms. The high-rigidity architecture and dual direct-drive rotary axes allow precise machining of free-form surfaces with minimal repositioning. This improves machining consistency, reduces setup time, and supports reliable mass production of lightweight, high-strength aerospace components.

Robotics & Automation Systems

Yangsen five-axis machining centers are used to manufacture robotic joints, humanoid hand articulation parts, structural housings, and sensor mounts. These parts often feature organic curves, complex angles, and deep cavities. The machine’s dynamic structure enables smooth, high-speed machining while maintaining micron-level accuracy, which is essential for motion-critical robotic systems.

Precision Mold and Tooling Manufacturing

For mold makers and finishing applications, the bridge-type and gantry-type models deliver the rigidity and thermal stability needed for long cycle finishing passes. These machines are commonly used for high-precision mold cores, graphite and copper electrodes, and complex cavity finishing where surface quality and repeatability are key requirements.

Automotive Powertrain and Engine Components

Yangsen models equipped with higher-torque motorized spindles and large-format trunnion tables are deployed in machining transmission housings, engine blocks, turbine parts, and powertrain system components. The high dynamic performance reduces machining time, while the optimized multi-axis configuration ensures accuracy for critical tolerance features.

3C Electronics & Small Precision Metal Parts

Our compact models are ideal for electronic device housings, small aluminum parts, and high-accuracy connectors. With high-speed spindles and agile motion response, they are suitable for fast-cycle, high-volume production of lightweight precision parts in consumer electronics, medical devices, and automation modules.

FAQ

1. What is the main difference between drill-tap type, vertical type, ram-type, bridge-type, and gantry-type models?

Each structure is designed for different part sizes and machining requirements:

Drill-tap platforms (U-260T) – compact size, high-speed machining for small precision components

Vertical models (U-320V / U-350V) – for precision machining of small to medium parts

Ram-type (YS-650-5X) – provides better accessibility for aerospace and structural components

Bridge-type (U-400D) – enhanced rigidity for mold and precision finishing

Gantry-type (U-400 / U-700 / U-900) – supports larger components like engine housings, robot joints, and turbine parts.

2. What control systems are available?

Depending on the model, Yangsen machines support Syntec, Huazhong, Siemens, FANUC, and Heidenhain controllers. Control compatibility varies based on configuration and spindle type.

3. What spindle specifications are available?

Spindle configurations include BT30/BBT30 direct-drive, BBT40 spindles, and high-speed HSK-A63 or HSK-A100 motorized spindle options (up to 24,000 rpm). The available spindle type depends on the machine structure and intended application.

4. Do you offer optional measurement and automation accessories?

Yes. Optional configurations include:
