HELLER H 14000 HORIZONTAL MACHINING CENTER

Technical Description

The HELLER H 14000 is a heavy-duty horizontal 4-axis machining center engineered for high stability, precision, and productivity in large-scale manufacturing. It features substantial axis travels of 94.488 inches (X), 62.992 inches (Y), and 62.992 inches (Z), supported by a robust cast iron machine bed and column ensuring high rigidity and damping during machining. The spindle delivers up to 57.7 horsepower with a maximum speed of 800 RPM, optimized for high-torque cutting applications. Tool management is handled by a CNC-controlled tool changer with a 50-tool capacity using an HSK 100A taper for rapid, precise tool changes, minimizing non-productive time. The machine utilizes a pallet system with 39.37-inch square pallets capable of supporting workpieces up to 4,000 kg, enhancing manufacturing efficiency for large components. The rotary axis (B axis) is an NC-controlled rotary feed table designed for continuous rotation with high circular milling torque, supported by a YRT bearing providing excellent rigidity and stability. Linear guideways use anti-friction roller bearings and ball screw drives, coupled with absolute measuring systems (glass scales) for accurate positioning and reduced tolerance. Control is managed via Siemens CNC technology (SINUMERIK 840D sl), ensuring seamless operation and integration. The overall dimensions of 399.6 x 328.7 x 210.6 inches reflect the machine’s substantial footprint suited for heavy-duty industrial environments. Thermal stability is maintained through precision cooling and thermal growth compensation systems. This machining center is ideal for complex, large-volume milling where precision, speed, and reliability are imperative.
