First produced in 2023, the Hamai N70 design is effectively a clean sheet of paper to address longer and larger workpieces as well as incorporating automation into the base and still maintaining a compact footprint. To that end the N70 incorporates a 15 Degree Slant-Type hob head design to facilitate chip disposal and more flexible automation in one stroke.
Featuring longer axial strokes, higher horsepower (& torque!) motors and a 15.9" color display, the N70 is capable of producing parts up to 120mm in diameter and 200mm in length. Standard for Hamai machines, the N70 also incorporates direct-drive work and cutter spindles. This machine are suitable for WET or DRY operations for cutting gears up to 2.5 Module / 10.316 DP. Coupled with the reliable Fanuc Series 31i CNC controls and drive system with conversational data input these machines are ideal for production & job shop environments.
Heavy duty design & construction make these machines absolutely ideal for high accuracy requirements on smaller gears. With various loading system options as well as optional skiving hobbing systems for hardened gears, these machines will be a welcome addition to your high-precision hobbing machine stable and will elevate your production to a whole new level.
Known for their heavy-duty construction, Hamai horizontal hobbers are known in tight circles for their high accuracy and stability in production applications. In many cases, gears are produced with similar AGMA quality levels as ground gears. As a stable platform for DRY cutting, these compact machines can be configured for dedicated or flexible production scenarios and can even be kitted out for skive hobbing of hardened gears.
The N70 model is the BASE model and comes equipped for the US Market with Options added (and available Options) per below.
