Benefits of 5-Axis CNC Machining

Rapid Model's advanced multi-axis machining delivers outstanding results.

Advanced precision & complexity

5-axis CNC machining allows us to create complex, organic geometries that would be impossible with traditional 3-axis machines. With simultaneous movement in five axes, we can approach the workpiece from any direction, eliminating the need for multiple setups.

Superior Surface Finish

Continuous tool contact with the workpiece maintains optimum cutting conditions, resulting in exceptional surface finishes and reduced need for secondary operations.

Reduced Production Time

Complex parts can be completed in a single setup, dramatically reducing production time and eliminating errors associated with repositioning.

Extended Tool Life

The ability to orient the cutting tool optimally reduces tool deflection and vibration, extending tool life and maintaining precision throughout long production runs.
