Highly Rigid Structural Design
- One piece double column bridge casting or three-piece which includes two columns and one bridge casting based on machine model.
- One-piece base casting.
- Wide-span saddle casting fully supports the Z-axis head in any machining direction.
- Y-axis linear guideways have a wide span, which provides greater support.
- Rigid Z-axis head casting is designed to avoid overhang, increase stiffness, and reduce vibration.
- Dual chip augers with conveyors provide efficient chip removal.
