F75 Twin Spindle Milling Head

The Gong Yang F75 Twin Spindle Milling Head is engineered to expand multi-directional, high-efficiency machining capabilities on vertical machine tools, seamlessly adapting standard equipment for multi-station cutting cycles. Featuring a compact footprint and ergonomic setup, the unit incorporates a 360° graduated dial for swift, precise orientation of the cutting tool, making it an ideal attachment for deep-pocket boring, slot milling, end-face trimming, and bevel chamfering across complex workpieces.

Engineered for dependable dynamic balance and extended service life, both the spindle shaft and drive gears are precision-machined from high-grade chromium-molybdenum alloy steel, rigorously quenched, hardened, and precision ground. Fitted with precision ball bearings optimized for high-speed operation and light cutting duty, the F75 delivers up to 38 KW of drive power, 1200 N.m of torque, and operating speeds up to 2000 RPM across standard #50 spindle tapers and cutter diameters up to ψ150 mm. The spindle is compatible with NT or BT shanks (BT pull studs must be removed, and dedicated matching drawbars can be specified upon order). The spindle is designed strictly for clockwise (forward) cutting rotation—reverse rotation is dedicated exclusively to tapping and counterboring cycles and must never be applied to milling or drilling—ensuring long-term geometric precision and operational reliability.
