Innovative Design Concepts
- The new U Series 5 Axis Machining Center gives your workshop the versatility to machine smaller less expensive components without the expense or large footprint of a swivel head machine.
- Double arm supported A/C axes.
- Using the integrated trunnion table design is the easiest upgrade path for 3 Axis machine workshops as the approach to part tooling is very similar and reduces the training time required for your operators.
- The X, Y, and Z axis on this machine all feature heavy duty roller type linear guideways to maintain precision positioning under rapid movement and heavy loading.
