4-axis CNC machining is essential for parts with features distributed across multiple faces. In aerospace it machines structural brackets and housings with tight angular tolerances. In medical device manufacturing it produces surgical instrument components and implant fixtures. In industrial equipment it creates complex valve bodies and pump housings. The single-setup advantage ensures consistent datums and tighter geometric tolerances.

Related to 4-Axis CNC Machining
In 3-axis CNC machining, the tool moves along straight X, Y, and Z axes. In 4-axis machining, a rotary A-axis is added, allowing the workpiece to rotate. This enables the machining of complex features on multiple sides without re-fixturing.
4-axis machining adds rotational capability, allowing features on multiple faces to be machined in a single setup. This reduces clamping time, improves accuracy between faces, and enables the production of cylindrical profiles and continuous spiral geometries.
Yes, we produce internal and external threads using thread milling or 4-axis spiral interpolation. Tapped holes in standard thread specifications are also available.
Although the hourly machine rate is slightly higher, 4-axis machining typically reduces total costs by minimizing the number of setups. For complex multi-sided parts, 4-axis machining is often more cost-effective than multiple 3-axis setups.
Parts requiring features on multiple faces, cylindrical surfaces, cam profiles, or helical geometries—and any part where continuous rotation is required during cutting—are perfectly suited for 4-axis machining.
Yes. We specialize in mass production with a 100-piece MOQ and can handle batches of 100,000+ units. Volume-based tiered discounts apply.
Choose 5-axis machining for complex 3D surfaces, deep cavities with small radii, undercuts, or when the highest precision is needed on multi-feature parts. 5-axis excels on impellers, turbine blades, sculptured surfaces, and any geometry requiring simultaneous rotary and linear axis movement.
In CNC turning, the workpiece rotates while the tool remains stationary, suitable for cylindrical parts such as shafts, pins, and sleeves. In CNC machining, the workpiece is stationary while the tool rotates, ideal for flat, prismatic and complex 3D geometric shapes.
