G-45D

Hydraulic Cylindrical Grinder Designed for Flexible Operations

The Shigiya G-45D is a hydraulic cylindrical grinder built to meet the demands of medium-size precision grinding. Its solid structure and wide range of capabilities make it ideal for manufacturers who need consistent performance across a variety of applications. With a swing over table of 450 mm (17.72 inches), the G-45D handles a range of workpiece diameters effectively. Moreover, its multiple center length options—from 1,000 mm to 6,000 mm—enable it to support parts up to 200 inches long. This combination of features allows the G-45D to work across diverse industries, such as transportation, aerospace, and general part manufacturing.

Manual Cylindrical Grinding with High Accuracy

Unlike CNC machines that rely on automation, the G-45D emphasizes hands-on precision. Operators can control every grinding pass, which improves accuracy and consistency. The manual cylindrical grinding process gives machinists direct control, ensuring that each component meets strict tolerances. Additionally, its hydraulic system provides smooth table movement, making operations more stable. As a result, users experience fewer dimensional errors and better surface finishes. The G-45D’s strength lies in its ability to repeat high-precision results.

Medium-Size Precision Grinder with Heavy Capacity

Although the G-45D is considered a medium-size grinder, it supports heavy parts with ease. Its capacity reaches up to 2,200 lbs (1,000 kg), giving it a competitive edge in its category. This means users can grind mid-to-large parts without sacrificing accuracy or requiring a full-size machine. Its heavy-duty design minimizes vibration, helping it maintain stability throughout long grinding cycles. With less vibration, the machine delivers more reliable finishes and tighter tolerance control, even when operating at full capacity.

Versatility for Job Shops and Production Lines

Whether you’re handling a custom job or a repeat production run, the G-45D adapts easily. Its range of center lengths and high weight capacity make it versatile for many applications. Because of this flexibility, it fits well in both high-volume facilities and small, specialized workshops. Moreover, the grinder’s design emphasizes ease of maintenance. That means operators spend less time adjusting the machine and more time focused on production. This reliability, combined with user-friendly operation, results in higher output and reduced downtime.
