MU-Series Cradle Five-Axis Machining Center (MU-400V / MU-500V)

Built for Complex, Multi-Face Geometry

The cradle five-axis machining center is intended for parts whose faces, angles and contoured features cannot be reached in a single three-axis setup: impellers, turbine and compressor components, medical constructions and precision molds. By tilting and rotating the workpiece on a trunnion, most of the part is finished with one tool orientation and one clamping.

The machine uses a simulated five-axis (3 + 2 tilt and rotate) architecture that keeps the structure rigid while still giving full access to compound angles.

Cradle (Trunnion) and Rotary Axes

The A/C trunnion carries the table between two rigid uprights, and both rotary axes use direct or backlash-free gearing to hold angular position under cutting load. Clamping on both axes locks the table during heavy cutting on a compound face.

• A axis: tilting table, typical range -120 to +45 degrees for selection
• C axis: continuous rotation for contouring and drilling around the part
• Rotary drive: high-torque and backlash-free for stable multi-face machining

Accuracy and Thermal Behaviour

Box-in-box structural castings and cooled ballscrews reduce the influence of heat over long cycles. Geometric accuracy on a cradle machine is defined per axis as well as in the combined A/C orientation, so a full accuracy report covering both is worth requesting.

Control and Automation Options

The control supports simultaneous five-axis interpolation, RTCP and tool-center-point management so that programming effort does not grow with the number of tool orientations. Optional tool setting, in-process probing and pallet or robot interfaces support unattended runs.

Reference Specifications

Typical values are listed for selection reference; the final configuration and quotation are subject to inquiry confirmation.

Selection Notes

Match swing diameter and maximum part weight first, then set the rotary indexing accuracy against your tightest tolerance callout. Where high-speed aluminum work dominates, consider the higher spindle-speed option; for mold work in hard materials, choose the higher-torque spindle.

Acceptance Points

Verify a five-axis test cut for tool-center-point behaviour, measure the actual A/C angular error and roundness on a sample impeller or mold insert, and confirm thermal stability over a long run before signing off.
