Introducing the New H90 Horizontal CNC Gear Hobbing Machine from SMG.
Engineered in South Korea by SMG, the all-new Model H90 sets a new standard for precision, flexibility, and efficiency in automated gear hobbing solutions. Designed from the ground up in collaboration with real-world users — both from SMG and competitive platforms — the H90 addresses key limitations of conventional machines with a forward-thinking, production-ready design.
At the core of the H90 is a powerful, compact hobbing solution with integrated automation, offering support for both puck- and shaft-style gears. It’s optimized for DRY & WET processing, built on a rigid, modular frame using proven componentry (from the Vertical SH Series platforms) for high-uptime and simplified maintenance.
With 100 mm of maximum workpiece diameter (with automation), the H90 is ideal for job shops and high-throughput environments alike. For manually loaded operations, it offers a generous 125 mm OD capacity, making it an excellent fit for precision manufacturers seeking a small footprint with big performance.
Key Features:
-Horizontal CNC gear hobbing with direct-drive technology.
-Modular automation architecture for manual or auto-load configurations.
-DRY / WET cutting compatibility.
-Available with Fanuc or Siemens CNC controls.
-Torque motor rotary tables, geared hob heads, and conversational programming.
-Includes a hob pre-setting device as standard.
With global installations running 24/7 in both job shop and volume production settings, the H90 is a robust, cost-effective answer for manufacturers who demand performance, reliability, and long-term flexibility.
