The SP-20, Star CNC's latest Swiss-type automatic lathe, is engineered to offer substantial versatility within a small footprint and at a modest price point, according to the company.

This compact solution can effectively machine material up to 1-inch in diameter. Its unique design features a gate-shaped tool post that encircles the guide bush for precise front-side machining. This setup is robustly equipped with 8 turning tools, a 5-position sleeve holder, and a 7-spindle power-driven tool unit offering 5 modular cartridge positions. The wide range of available modular units, including Cross Drilling, Front Drilling, Slotting, Thread Whirling, and Polygon Machining, significantly enhances the machine's overall versatility and range of machining options.

Further maximizing efficiency, the SP-20 includes key features designed to boost productivity and finish quality. It is equipped with a full B-axis capability on the modular tool unit, allowing for complex angled holes and contoured surfaces without secondary operations.
A high-pressure coolant system is also integrated to ensure optimal chip evacuation and prolonged tool life, even when working with challenging materials like stainless steel or titanium. The machine control incorporates a user-friendly interface that streamlines programming and setup times, reducing the learning curve for operators.
For high-volume production environments, the SP-20 offers sophisticated automation integration options.

Standard features include an automatic bar loader interface and a parts catcher/conveyor system to facilitate continuous, lights-out operation. The machine's rigid construction and advanced thermal compensation system ensure consistent precision throughout extended production runs, minimizing dimensional variations. This blend of compact size, comprehensive tooling options, and automation-ready design makes the SP-20 a powerful and cost-effective solution for diverse manufacturing needs.
