3-axis CNC milling machine Portalo C 2519 CNC

verticalwith moving tablegantry

Description
The Portalo C 2519 CNC is a gantry-type 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 material removal as well as high-speed machining of dies and complex shapes.

Highlights

• High workpiece weight capacity
• Large machining area
• Rigid fixed gantry
• Quick-action 24-position tool changer
• Renishaw tool and workpiece measuring systems

Design and build
The movable setup table combined with a rigid fixed gantry enables machining of large, heavy parts. A combination of linear guides and box/flat ways delivers long service life, high machining speeds and sustained rigidity. Preloaded ball screws and Siemens servo motors provide dynamic and rapid feeds across all axes.

Main spindle

• High drive power and a wide speed range deliver the torque reserve required for heavy cutting operations

Tool changer

• Robust 24-station tool changer with dual-arm gripper for flexible and rapid tool changes

Control

• Siemens 828D control offers intuitive programming and strong service support
• Siemens Shopmill software included to simplify production of complex contours and workpieces

Equipment

• Large sliding doors on the enclosure for easy access and loading
• Renishaw measuring systems for tool and workpiece probing to reduce setup errors and downtime
• Powerful coolant system and included chip conveyor for reliable chip removal
• Automatic central lubrication system for simplified maintenance
