YAMA SEIKI GT-200 is a compact CNC turning center designed for high-precision machining of small to medium-sized components in job shop and production environments. It features a rigid slant-bed cast iron structure that provides excellent vibration damping and thermal stability, ensuring consistent machining accuracy during high-speed turning operations. The GT-200 is suitable for machining a wide range of materials, including aluminum, steel, stainless steel, and engineering plastics, and is commonly used in automotive components, electronics, medical parts, and general precision manufacturing applications.
The GT-200 is typically equipped with a high-speed spindle and a servo-driven turret system that enables rapid tool indexing and reduced cycle times. Advanced CNC control systems offer high-speed data processing, smooth contouring, and intuitive programming capabilities, supporting complex turning operations with high repeatability. Optional features such as live tooling, sub-spindle, and tailstock allow drilling, tapping, and secondary operations to be performed in a single setup, improving productivity and reducing part handling. Precision linear guideways and high-performance servo drives further enhance positioning accuracy and surface finish quality.
Yama Seiki engineered the GT-200 for durability and continuous industrial use, with robust mechanical components, efficient chip management, and automation-ready features for integration into modern manufacturing systems. Its compact footprint, combined with rigidity and precision, makes it a dependable solution for manufacturers seeking efficient and accurate turning performance in limited floor space.
