The Shigiya GNW-20 is a compact cylindrical grinder optimized for non-round and complex profile grinding. It delivers precise, repeatable results through rigid machine construction, accurate axis synchronization, and stable thermal performance. As a result, the GNW-20 supports reliable production of camshafts and other non-cylindrical components while maintaining tight tolerances and consistent surface quality.
The Shigiya GNW-20 is a powerful 2-head CNC grinder designed for the efficient and accurate production of small components. Featuring a twin wheel head grinder setup, this machine performs simultaneous grinding on multiple surfaces. As a result, manufacturers benefit from reduced cycle times and improved output. Each part is ground with reliable uniformity, thanks to the synchronized driving work heads that maintain tight tolerances throughout the process. In addition, the GNW-20’s robust mechanical structure supports high-speed grinding without compromising precision or part quality.
The GNW-20 isn’t just fast—it’s smart. As a simultaneous grinding machine, it integrates dual grinding operations into one seamless cycle. Because of its compact layout, this machine is ideal for production environments where floor space is limited. Moreover, it includes center grind work heads, allowing operators to perform both face and diameter grinding in a single setup. This setup reduces the need for multiple machines and minimizes part repositioning, which often introduces error. With less manual handling, the GNW-20 helps maintain part integrity and production flow.
Designed for efficiency, the GNW-20 fits the role of a compact cylindrical grinder perfectly. It’s engineered specifically for small part manufacturing, making it a standout option in industries like aerospace, medical, and automotive. With a swing over table of 200 mm (7.87 inches) and a distance between centers of 100 mm (3.94 inches), this grinder handles intricate work with ease. Its CNC control system ensures accurate performance on every pass. Thanks to its optimized layout, it combines precision grinding with space-saving practicality—something many modern production lines demand.
Accuracy matters, especially in applications where the smallest deviations can affect performance. That’s why the GNW-20 is trusted as a high-precision CNC grinder. Its rigid frame and dynamic control system ensure stable operation even at high speeds. Consequently, it produces clean, consistent finishes with minimal variation from part to part. In addition to its performance, the machine is simple to maintain and easy to operate, which makes it a smart investment for long-term reliability.
