The VISION WIDE SF-4120 3-Axis Double Column Machining Center is a long-stroke, high-capacity, bridge-type model within the SF Series, featuring an expansive 4,100 mm X-axis travel and an expanded 2,000 mm Y-axis travel for extra-large and wide workpieces. Engineered for high efficiency and long-term accuracy and stability, its robust full-casting design is optimized for fine components machining and mold cutting, combining superior structural integrity with high dynamic performance.

Key Specifications and Maximum Capacity

The SF-4120 is configured for maximum capacity and precision across its massive work area:

• Full Casting Structure: Features a full casting structure and an ultra-wide column that provides the best rigid support for the spindle, ensuring stability and long-term accuracy across the entire 4,100 mm travel.
• Dynamic Accuracy: The ultra-wide base of the X-axis and thick, high-rigidity table enhance the table load capacity (up to 12,000 kg) and guarantee the best dynamic level accuracy during high-speed operation.

Speed and Precision Features

The machine utilizes high-speed motion for efficient contouring across the large work area:

• High-Speed Motion: The machine is designed with 3-axis linear ways (on most options) for rapid traverse speeds up to 24 m/min in X/Y and 15 m/min in Z. The 10,000 mm/min cutting feed rate is crucial for high-speed mold machining and reducing cycle times.
• Versatile Spindle: Standard configuration includes a 6,000 RPM 2-step gear type spindle (box way Z-axis) for high-torque cutting, with options available for 10,000 or 12,000 RPM direct-driven or built-in spindles for high-speed finishing.
• Automation: Comes standard with a 32-tool arm-type ATC for efficient tool management.
