The Shigiya G-85D is a large-scale cylindrical grinder built for precision machining of very large, high-weight components. It maintains consistent accuracy through an exceptionally rigid structure, stable thermal characteristics, and reliable grinding performance during long run times. As a result, the G-85D supports dependable production and consistent part quality in heavy industrial grinding applications.
The Shigiya G-85D is a powerful hydraulic cylindrical grinder built for large-scale machining. With a swing over table of 850 mm (33.46 inches) and a center distance of up to 236 inches (6,000 mm), it handles heavy workpieces with ease. Furthermore, it supports loads up to 6,600 lbs, which makes it well-suited for industries like aerospace, shipbuilding, and energy. Because of its large capacity and precision engineering, manufacturers can trust it to maintain dimensional accuracy across long components. Whether you’re grinding shafts, cylinders, or structural parts, this machine delivers consistent results.
As a conventional cylindrical grinder, the G-85D relies on manual controls rather than complex automation. This gives skilled machinists the ability to fine-tune operations as needed. That level of hands-on control allows for more accurate, on-the-fly adjustments—especially useful when dealing with unique or variable part geometries. Moreover, the layout is intuitive. Operators can easily access critical functions, and the manual system reduces the risk of software or control errors. This simplifies training and daily use while ensuring the highest level of grinding quality.
The G-85D is not only large—it’s built to last. Its heavy-duty grinding machine structure offers maximum rigidity during high-force operations. That strength eliminates unwanted movement and significantly reduces vibration during grinding. As a result, users see better surface finishes and tighter tolerances. Additionally, the reinforced frame minimizes thermal expansion. This stability ensures repeatable accuracy, even during long grinding cycles or in high-volume production environments.
The G-85D represents the best of Shigiya machine tools—durable, adaptable, and precise. It accommodates a wide range of part sizes and materials, making it a versatile grinder for many production tasks. Whether you’re running small batches or high-volume orders, the G-85D adapts with minimal changeover. Furthermore, its manual design offers more flexibility compared to fully automated grinders. With a balance of control and power, the G-85D delivers both productivity and precision.
