G-30B

Hydraulic Cylindrical Grinder for Consistent Accuracy

The Shigiya G-30B is a hydraulic cylindrical grinder built for precision and reliability. It offers a standard-size platform that’s ideal for shops handling medium to large workpieces. With a swing over table of 300 mm (11.81 inches) and multiple center distance options—ranging from 400 mm to 2000 mm—this machine adapts easily to varied production demands. As a result, the G-30B supports both short-run toolroom tasks and larger volume jobs. Thanks to its hydraulic table drive and balanced design, the G-30B performs smooth, consistent movement during grinding. This contributes to accurate finishes across a wide range of part geometries.

Precision Grinding Machine for Tight Tolerances

This precision grinding machine is engineered to minimize vibration and thermal distortion, both of which can reduce part quality. The rigid wheelhead and tailstock provide solid support for the workpiece, enhancing stability. Because of this, operators can count on consistent performance, even during long runs. Additionally, its straightforward controls make operation intuitive. Operators get direct control of grinding passes, feed rates, and dressing, without needing complicated setup procedures.

Universal Cylindrical Grinder for Versatile Jobs

The G-30B is more than just a surface grinder. As a universal cylindrical grinder, it handles external, internal, and face grinding—all on a single machine. This versatility makes it valuable for diverse manufacturing needs. Whether you’re producing automotive components, aerospace tooling, or industrial shafts, this grinder delivers reliable precision across each process. Moreover, the ability to perform multiple operations in one setup reduces part handling and speeds up throughput. That helps manufacturers boost productivity while maintaining tight tolerances.

Standard Size Grinder with High Capacity

Although compact in layout, the G-30B is powerful enough to manage heavier parts. With a load capacity of up to 150 kg (330.69 lbs), it supports grinding for a wide range of materials and component sizes. Its standard footprint means it fits into most production environments without the need for extra floor space. Combined with its heavy-duty construction, this capacity ensures long-lasting performance—even in demanding applications.
