SNK FNC-150

The SNK FNC-150 is a table-type CNC horizontal boring and milling machine with a 150 mm diameter spindle, manufactured by SNK America Inc. (Shibura-Nikosei Kiko) in Japan. SNK has a long history of producing large-format horizontal machining centers and boring mills for aerospace, heavy industrial, and energy applications, and the FNC-150 represents the upper end of their table-type boring mill platform targeting heavy-duty prismatic component machining.

The FNC-150 features a rigid box-column construction with a 150 mm spindle delivering high torque across its full gearbox speed range of 1 to 2,000 RPM. Spindle power is rated at 55–75 kW depending on configuration, enabling aggressive roughing cuts in steel and cast iron alloys as well as precision finishing passes on precision bearing bores and sealing faces. The table travel in the X-axis extends to 4,000 mm and the CNC rotary B-axis table supports workpieces up to 25,000 kg — accommodating large gearbox housings, turbine casings, and heavy pump and valve bodies.

The headstock (Y-axis) travels vertically to 3,000 mm, providing access to tall workpieces without raising the floor level. A 900 mm W-axis spindle quill extension adds reach without column movement for deep-bore operations. The Z-axis column travel of 2,000 mm provides the fore-aft positioning range needed for large multi-face programs. This five-axis (X, Y, Z, W, B) arrangement, controlled by the Fanuc 30i-B or Fanuc 31i-B5 CNC, provides comprehensive coverage of complex prismatic machining tasks.

SNK integrates an automatic tool changer with up to 80 positions, supporting the wide variety of boring bars, milling cutters, drills, and taps needed for complex large-part programs. SNK America's presence in the United States provides local service and application support — an important advantage for North American buyers of large Japanese boring mills who require fast on-site response when maintenance issues arise on these high-value assets.
