YAMA SEIKI GOODWAY SW-20 HORIZONTAL MACHINING CENTER

Technical Description

The YAMA SEIKI GOODWAY SW-20 is a precision Swiss turning center engineered for high-speed micro-machining of complex components. Featuring dual spindles, the machine accommodates workpieces up to 0.790" (20mm) in diameter with a maximum turning length of 3.140" (207mm) for the sub-spindle. The primary spindle operates at 10,000 RPM with 5.0 HP output, while the sub-spindle reaches 8,000 RPM with 3.0 HP, enabling simultaneous machining operations on multiple surfaces. The tooling system comprises six turning tools on the OD slide and four on the ID slide, allowing two simultaneous cutting tools to function independently. The 5-axis CNC architecture provides comprehensive control for turning, milling, drilling, and tapping operations. Equipped with standard secondary mill/drill capabilities both on-center and off-center, plus integrated C-axis and Y-axis functionality, this machine executes intricate multi-axis coordinate motions with precision. The hybrid guide bush design permits both bush and bushless operating modes depending on machining requirements, enhancing versatility. Built-in spindle motors ensure quiet, reliable operation with rapid axis traversal at 20 m/min. Controlled by FANUC 31i-TB system with advanced diagnostics, the SW-20 delivers high-precision results ideal for automotive, electronics, medical device, and watchmaking industries requiring micro-component production with tight tolerances and complex geometries.
