The Shigiya GPH-20 is a compact cylindrical grinder designed for high-precision internal and external grinding of small to medium-sized components. It delivers consistent, repeatable accuracy through a rigid machine structure, precise spindle control, and stable thermal performance over long production runs. As a result, the GPH-20 supports reliable machining of tight-tolerance parts while maintaining predictable grinding quality.
The GPH-20 is a compact yet robust CNC cylindrical grinder designed to meet the growing demands of high-precision, small-part production. While its footprint is minimal, the machine offers serious capability. Its solid construction ensures stability, while the control system delivers reliable performance every time. Because this CNC cylindrical grinder supports high-speed operation and tight tolerances, it fits well into medical, aerospace, and electronics shops where small parts demand big precision.
The GPH-20 delivers consistent results as a high-precision grinding machine, even across extended production runs. Its high-rigidity wheel head, thermally stable frame, and servo-driven table provide excellent repeatability and finish quality. Furthermore, this high-precision grinding machine simplifies setup while allowing for tight control of part geometry. Shops that rely on micron-level accuracy will find the GPH-20 to be a valuable long-term investment.
One of the GPH-20’s key advantages is its inclusion of manual feed hand wheels. These hand wheels allow operators to make fine adjustments during low-volume or prototype grinding. In addition, the manual feed hand wheels offer tactile control during setup without compromising CNC automation. For small shops or mixed-production environments, this flexibility makes the GPH-20 a smarter, more versatile choice.
With full CNC capability and automation readiness, the GPH-20 supports a wide range of automated grinding solutions. It integrates easily with robotic loaders, conveyors, and in-line part handling systems. These automated grinding solutions allow manufacturers to reduce labor costs, improve consistency, and increase output. Whether operating in single-shift or lights-out environments, the GPH-20 supports modern production goals.
The GPH-20 excels as precision machining equipment tailored for delicate geometries and high-tolerance applications. It provides accurate control across the entire grinding cycle. Moreover, as a small parts grinding machine, it handles fine-featured components with confidence. Whether producing medical pins, bearing races, or small shafts, the GPH-20 delivers accuracy, repeatability, and long-term reliability.
