Description

Machines of the Portalo C CNC series are specifically designed for precision machining of large and heavy workpieces. The machine frame features a fixed gantry and a movable table. The machines in this series are perfect solutions for heavy-duty machining and high-speed machining of complex dies and forms. An extensive assortment of standard equipment allows for easy adaptation for specific requirements.

Features

• High workpiece weight
• Large work area
• Rigid fixed portal
• Quick-action tool changer
• The movable set-up table and a fixed gantry allow machining of large and heavy workpieces

Gantry

• The large machining area and long travel distances require an extra rigid gantry and guide solutions for the most stringent requirements
• A combination of linear guides and box ways ensure a long service life plus higher machining speeds and steadfast rigidity
• High-quality preloaded ball screws and proven Siemens servo-motors provide dynamic feed and rapid feed on all axes

Main spindle

• High drive power and a wide speed range ensure availability of the necessary torque reserves during heavy-duty machining

Tool Changer

• The robust 24-station tool changer features a dual-arm gripper for maximum flexibility and quick tool changes during production

Control
