Tsugami Precision Swiss CNC machine tools now offer 20-mm models—the S205 and S206. These machines were designed to provide Swiss technology users with the flexibility and capability to meet a range of needs. The models feature a modular tool zone similar to that found in the SS series, but offer a lighter frame and faster spindle speed, according to the company.

Both machines are especially suited for the production of complex parts. Live tools for cross and face operations are found on the main and subspindle. A two-path control permits true simultaneous operation of the main and subspindle, dramatically reducing cycle times. The modular and roomy tool zone allows driven tools to be moved from main to subspindle and from face to cross positions with ease by the operator, minimizing downtime between different jobs.

The S206 has the same capabilities of the S205 plus backworking Y-axis movement. A Fanuc 31-iA control is standard on both models, which also can accommodate an optional “chucker kit” that allows the machine to be run as a Swiss turning machine or fixed headstock lathe. The fixed headstock configuration can use unground barstock, eliminating costly bar remnants and improving part concentricity, the company says.
