Description
The Chester VF760 High Speed Ultra Performance CNC Machining Centre features advanced machine design has a reinforced body structure through FEM analysis and extra wide machine column and base design to ensure the high rigidity during high speed movement. The VF series offers superb cutting performance and reduced vibration to meet the highest machining demands.
Our CNC Machining Centres offer:
- High speed performance and high rigidity for precision machining
- High spindle torque
- BBT spindle for higher rigidity
- Roller type linear guideway
- Direct drive provides backlash free, best accuracy, reliability and stability
- Cast iron is tempered for stress relief to ensure structural stability without deformation
- C3 class ballscrews ensures the highest accuracy and durability
- Pre-tension on all axis minimizes thermal distortion
