verticalwith moving tablegantry

Overview
The Portalo C 2014 CNC is a CNC gantry milling machine designed for precision machining of large and heavy workpieces. The machine features a fixed gantry and a movable table, making it suitable for heavy-duty and high-speed machining of complex dies and forms. A broad range of standard equipment enables adaptation to specific production requirements.

Highlights

• High workpiece weight capacity (table load up to 4,000 kg)
• Large working area (table 2,000 x 1,200 mm)
• Rigid fixed gantry design for sustained stiffness
• 24-position quick-action tool changer with dual-arm gripper
• Renishaw tool and workpiece measuring systems

Product Details
The movable set-up table combined with a fixed gantry enables machining of large and heavy workpieces while keeping setup accessible and efficient.

Gantry

• Extra-rigid gantry and guide solutions ensure stability across long travel distances
• Combination of linear guides and box ways provides extended service life and higher machining speeds
• Preloaded ball screws and proven servo motors deliver dynamic feeds and rapid traverse on all axes

Main spindle

• High drive power and wide speed range supply required torque reserves for heavy-duty cutting (spindle speed up to 6,000 1/min, SK 50)

Tool Changer

• Robust 24-station tool magazine with dual-arm gripper for quick tool changes and flexible production

Control

• Siemens 828D control provides intuitive programming and industry support
• Siemens Shopmill software included to simplify production of complex contours and workpieces

Equipment

• Large sliding doors on the machine enclosure for easy access and tooling
• Renishaw measuring systems for tool and workpiece gauging to reduce downtime and scrap
• Powerful coolant system with chip conveyor for efficient chip disposal
• Automatic central lubrication system to simplify maintenance
