The Shigiya GAC-40B is a high-capacity angular cylindrical grinder built for precision grinding of larger, more complex workpieces. It delivers stable, repeatable accuracy through a rigid machine structure, precise axis control, and consistent thermal performance during extended production runs. As a result, the GAC-40B supports dependable throughput while maintaining tight tolerances and consistent part quality.
The GAE-30B is a compact yet powerful CNC angular cylindrical grinder designed to meet the demands of high-accuracy machining. Engineered with rigidity and thermal stability in mind, this high-precision grinding machine ensures stable, repeatable results for shops working with tight tolerances. With its integrated design, the GAE-30B offers outstanding consistency, especially in production environments where quality cannot be compromised. It minimizes vibration and thermal drift, which is essential for precision components used in aerospace, automotive, and industrial manufacturing.
This model features a true dual-axis control grinder configuration, allowing operators to control the X and Z axes independently. That means greater control over wheel positioning and part movement—critical for parts that require multiple grinding passes. By enhancing control over both axes, the dual-axis control grinder architecture supports tighter finishes and faster changeovers. Operators can rely on smooth, predictable movement across each cycle. As a result, productivity increases without sacrificing the surface quality or dimensional accuracy of the part.
Whether working with OD, face, or shoulder geometries, the GAE-30B functions as a versatile CNC grinder that supports a wide variety of part shapes. It easily handles straight, tapered, and contoured components in a single setup, thanks to its 30-degree angular wheel head design. As a versatile CNC grinder, it simplifies operations and reduces total machine time. It’s particularly useful for mixed-volume production where flexibility is a must. This adaptability helps shops maintain throughput while managing diverse customer demands.
The GAE-30B isn’t just precise—it’s tough. Built as a heavy-duty cylindrical grinder, it handles large and small workpieces alike without losing accuracy. Its robust base, servo-driven slide systems, and rigid wheelhead structure allow it to perform under pressure. From rough grinding to fine finishing, this heavy-duty cylindrical grinder delivers both performance and longevity. As a result, manufacturers enjoy increased uptime and lower total cost of ownership over the machine’s life cycle.

The Shigiya GAE-30B is a CNC angular cylindrical grinder for OD diameters and locating faces or shoulders that must be controlled from one setup. A.W. Miller Technical Sales supplies and supports Shigiya grinding equipment throughout New York, Pennsylvania, Maryland, Delaware, Southern New Jersey, and Quebec, with application engineering, installation, training, and factory-certified service.
The 30-class angular platform combines radial and face-grinding access. Swing, center distance, wheel angle and width, workhead capacity, and the specific automation or gauging package vary among the GAS, GAE, and GAC configurations. Final machine selection should be based on the complete workpiece, stock allowance, tolerance, surface finish, wheel and dressing package, workholding, gauging, coolant system, automation target, and production rate.
Applications commonly evaluated for the Shigiya GAE-30B include:
An angular wheel approach reaches cylindrical surfaces and adjacent locating faces while the part remains referenced in one setup.
Wheel form, dressing, corner radius, and approach path must be coordinated where a journal meets a critical shoulder or face.
Abrasive type, grade, bond, wheel dimensions, dress form, and dressing interval must be matched to material, stock allowance, finish, and cycle time. The GAE-30B process should be validated with the complete wheel and coolant package.
Centers or chucking, drive method, support, coolant filtration, temperature control, and gauge strategy determine whether the GAE-30B can hold the required size, roundness, cylindricity, and surface finish through production.
GAE-30B is configured for OD diameters and locating faces or shoulders that must be controlled from one setup. The exact operation set depends on wheelhead configuration, dressing, workholding, gauging, and the geometry that must remain tied to one setup.
Review swing, maximum grinding diameter, distance between centers or chuck envelope, supported mass, wheel clearance, steady-rest space, and loading access. Catalog capacity should be reduced by the real fixture and tooling package.
Common evaluations include shafts requiring OD and shoulder-face grinding, bearing seats and locating faces, gear and transmission shafts, precision stepped components. Material, stock allowance, tolerance, surface finish, annual volume, and current cycle time determine whether the application is technically and economically appropriate.
Accuracy depends on machine condition, foundation, warm-up, coolant temperature and filtration, wheel balance, dressing, work support, gauging, and compensation. The process capability must be established against the drawing requirement.
A.W. Miller should review the part print, material and hardness, incoming condition, stock allowance, grinding diameters and lengths, tolerance, finish, takt time, loading, gauging, dressing, coolant, and facility requirements.
