YAMA SEIKI GA-330 is a compact CNC turning center designed for high-precision machining of small to medium-sized components in production and job shop environments. It features a rigid slant-bed cast iron construction that provides excellent vibration damping and thermal stability, helping maintain consistent accuracy during high-speed turning operations. The GA-330 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.
The GA-330 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 provide fast data processing, smooth contouring, and intuitive programming capabilities, supporting complex turning operations with excellent repeatability. Optional features such as live tooling, sub-spindle, and tailstock allow the machine to perform drilling, tapping, and secondary operations 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 GA-330 for long-term reliability and ease of integration into automated production environments, with robust mechanical components, efficient chip management, and automation-ready interfaces. 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.
