The Shigiya GAS-40B is a universal cylindrical grinder built for high-precision grinding of larger and more complex workpieces. It delivers consistent accuracy through a rigid machine structure, smooth multi-axis motion, and stable thermal performance over long production runs. As a result, the GAS-40B supports flexible manufacturing while maintaining tight tolerances and repeatable part quality.
The Shigiya GAS-40B is a high-performance CNC angular cylindrical grinder built for grinding long and complex cylindrical parts with consistent accuracy. Designed for demanding machining applications, it features a large-diameter wheel spindle that supports aggressive material removal. Because of this enhanced capacity, the GAS-40B is ideal for industries that require precise and durable grinding solutions. Additionally, the rigid tailstock design provides outstanding support to long and heavy workpieces, ensuring stability throughout the entire grinding cycle. This rigidity directly improves accuracy and finish quality, which is critical for high-tolerance components.
What sets the GAS-40B apart is its ability to perform simultaneous O.D. and shoulder face grinding. Instead of moving the workpiece between multiple operations, this grinder completes both in one pass. As a result, it reduces setup time and ensures consistent alignment, which helps increase productivity and part consistency. This dual-function grinding method is particularly useful in production settings where reducing downtime is a priority. It also minimizes operator intervention, making it easier to maintain part quality over long production runs.
With a swing over table of 16.14 inches and the ability to handle parts up to 37.41 inches between centers, the GAS-40B accommodates a broad range of cylindrical workpieces. The grinding wheel itself measures up to 24.02 inches in diameter, giving users the ability to perform deep or wide cuts when needed. Thanks to its 14.75 to 20.12 HP wheel spindle, this grinder handles both fine finishes and high stock removal with ease. Whether grinding hardened materials or performing final surface operations, it delivers smooth, repeatable results.
In industries where reliability, performance, and speed matter, the Shigiya GAS-40B stands out. From automotive components to aerospace tooling, this grinder meets tight specs while maintaining high throughput. With its rigid structure, advanced CNC capabilities, and multi-operation design, it’s a perfect fit for high-volume precision grinding environments.
