4 Axis CNC machining

4 Axis CNC machining integrates a rotary axis—typically a turning fixture—perpendicular to the standard X, Y, and Z axes. This additional B-axis rotation allows the cutting tool to approach the workpiece from four distinct directions without manual re-clamping. The outcome is fewer setups, streamlined workflows, and the ability to produce intricate features such as helical shapes, undercuts, and deep cavities

Key Benefits:

We offer high-quality 4-Axis CNC machining with the following advantages:​

  • Reduced Setup Time & Costs
    Fewer part re-clamps mean less downtime and lower labor expenses.

  • Higher Precision & Accuracy
    Consistent tool-to-workpiece angles achieve tighter tolerances (±0.005 mm or better).

  • Superior Surface Finish
    Continuous rotary cutting avoids step marks, delivering smoother contours.

  • Complex Geometry Capability
    Machine hooked, angled, or spiral features in one go—ideal for turbine blades and medical implants.

  • Expanded Material Range
    From aluminum and stainless steel to titanium and high-performance plastics.

Applications:

4 Axis CNC machining powers critical industries where complexity and precision converge:

  • Aerospace: Turbine blades, structural brackets, and housings.

  • Automotive: Custom camshafts, manifolds, and prototype parts.

  • Medical: Surgical instruments, orthopedic implants, and dental prosthetics.

  • Mold & Die: Intricate mold cavities and undercuts without multiple fixtures.

Functional Prototyping & Validation with 4-Axis CNC Machining

4-axis CNC machining is not only ideal for rapid prototyping but also excels in functional validation, delivering prototype components with the precision and material properties needed for real-world testing . By producing parts that closely mimic the mechanical strength, thermal resistance, and surface finish of final production components, engineers can perform rigorous fit, form, and function tests under actual operating conditions—whether it’s load-bearing assemblies or intricate gears . Early detection of design flaws through these functional trials enables prompt iteration, significantly reducing time-to-market and minimizing costly revisions during full-scale production
