SIP SPC 7120 SIP HORIZONTAL MACHINING CENTER

Technical Description

The SIP SPC 7120 is a high-performance horizontal machining center designed for precision and heavy-duty applications. It features a robust 24.8" x 24.8" table size with an optional expansion to 31.5" x 31.5", supporting workpieces up to 3,300 lbs. The horizontal spindle employs an HSK-A 100 taper, a hollow 1:10 taper system known for enhanced rigidity and precision through dual contact points at the flange and taper, making it ideal for moderate to high-speed machining tasks. The standard spindle speed reaches up to 6,000 RPM, with an optional upgrade to 15,000 RPM, powered by a 68 HP motor rating, upgradable to 93 HP, ensuring strong torque and power delivery. Equipped with a 60-tool automatic tool changer (ATC) chain or tower, extendable to 240 tools, the machine supports high productivity and flexibility in tooling. The axis configuration includes four axes (X, Y, Z, and a full 360° B-axis rotation) with travels of 47.2" (X), 37.4" (Y), 47.2" (Z), and continuous B-axis rotary motion, each axis capable of rapid and feed rates up to 1,572 inches per minute, maximizing machining efficiency. The machine's design supports complex multi-axis machining with high feed rates and rapid returns. The combination of the HSK-A 100 spindle taper and robust powertrain ensures precision clamping and high machining rigidity, suitable for demanding horizontal milling operations.
