The STM S3 International Variant is designed to deliver uncompromising accuracy, stability, and speed, making it the ideal choice for manufacturers seeking maximum productivity and performance.
With a generous travel range of 760 x 450 x 500 mm and a spacious 900 x 450 mm table, the STM S3 handles a wide variety of machining applications with ease. Its BBT40 spindle options, available in both belt drive (8,000–12,000 RPM) and direct drive (8,000–15,000 RPM) configurations, give users the flexibility to match spindle speed with their production needs. The G1-grade balanced spindle ensures excellent surface finishes of up to 0.45Ra, while extending tool life.
The STM S3 is built on an ‘A’-shaped structured column with multiple cross ribs and a wide casting base, providing superior rigidity, vibration dampening, and stability even under heavy cutting loads. Precision LM Ball Guideways on all three axes further enhance cutting dynamics and ensure long-lasting accuracy.
To maximize productivity, the STM S3 achieves a cutting feed rate of 10,000 mm/min and rapid traverse speeds up to 48 m/min. Combined with advanced Mitsubishi and Fanuc CNC controllers, the machine delivers intuitive operation, fast cycle times, and consistent results.
