The SNK HPS120B is a world-class 5-axis high-speed profiler designed for machining large and complex aerospace components with exceptional precision and productivity. Manufactured by Shin Nippon Koki Co., Ltd. (SNK), the HPS120B is engineered specifically for high-speed aluminum machining, structural aerospace parts, and other large contoured components requiring simultaneous 5-axis capability. The 2026 model is especially desirable because it offers the latest control technology, improved spindle performance, and modern automation features while retaining the proven architecture that has made the HPS series a benchmark in the aerospace industry.
The 2026 SNK HPS120B typically features approximately 124 inches of X-axis travel, 52 inches of Y-axis travel, and 30 inches of Z-axis travel, along with a large 48 x 120 inch table capable of supporting up to 11,000 pounds. The machine is equipped with a powerful 50-taper spindle rated up to 12,000 to 15,000 RPM and 50 hp or more, depending on configuration. Its 5-axis spindle head provides ±90 degrees of A-axis tilt and ±270 degrees of C-axis rotation, enabling full simultaneous contouring of large structural parts. Most machines are fitted with a FANUC Corporation 31i-series CNC control, through-spindle coolant, tool measurement systems, and 40- to 60-position automatic tool changers. Published listings for HPS120B machines consistently show this large travel envelope and aerospace-focused configuration.
The HPS120B is widely used in aerospace, defense, and advanced manufacturing. Typical applications include wing ribs, fuselage frames, bulkheads, monolithic aluminum components, and other large structural parts where accuracy, speed, and surface finish are critical. The horizontal-style profiler design improves chip evacuation and provides excellent access to complex workpieces, significantly reducing cycle times and manual intervention.
The 2026 SNK HPS120B remains an exceptional investment because it combines massive machining capacity, true simultaneous 5-axis capability, and the reliability demanded by the world’s most demanding manufacturers.
