The Shigiya GAS-30B is a universal cylindrical grinder built for flexible, high-precision grinding across a wide range of part geometries. It delivers stable accuracy through a rigid machine structure, smooth axis motion, and consistent thermal performance during extended operations. As a result, the GAS-30B supports adaptable production while maintaining tight tolerances and reliable part quality.
The Shigiya GAS-30B CNC angular cylindrical grinder delivers reliable heavy-duty precision grinding for demanding machining operations. Designed for tough environments, this grinder handles complex jobs with strength and accuracy. Its rigid structure ensures consistent results and long-term durability. Manufacturers trust this machine for high-accuracy machining. Its solid bed design and powerful wheelhead allow fast, accurate cuts. With the GAS-30B, operators complete more work in less time, and they maintain high-quality standards.
The CNC angular cylindrical grinder features a 30-degree angle wheelhead. This design allows multiple surfaces to be ground in one setup. As a result, changeovers are faster, and cycle times drop. Because the control system is intuitive, machinists can make real-time adjustments with ease. This feature boosts shop flexibility and helps meet tight delivery schedules. The CNC angular cylindrical grinder also increases part precision by reducing human error.
The GAS-30B excels at both OD grinding and shoulder face grinding. Thanks to its angular approach, the wheel contacts surfaces at an ideal angle. This improves accuracy and finish while lowering tool wear. During OD grinding, users get consistent diameters and tight tolerances. For shoulder face grinding, the machine maintains squareness and clean transitions. Whether the job is large or small, the GAS-30B handles it with control and confidence.
Manufacturers across industries rely on this machine for critical grinding work. Its design supports high-accuracy machining in applications ranging from aerospace to general manufacturing. Shops count on its uptime and performance to meet production goals. This CNC angular cylindrical grinder offers exceptional value. It combines power, speed, and precision to deliver heavy-duty precision grinding every day. With the GAS-30B, shops improve part quality while saving time and cost.

The Shigiya GAS-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 GAS-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 GAS-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 GAS-30B can hold the required size, roundness, cylindricity, and surface finish through production.
The difference is not limited to nominal swing. Center distance, grinding diameter, supported mass, wheel size, machine footprint, loading method, and available options may change, so both models should be compared against the same representative part family.
It can be configured for precision grinding, but achievable capability depends on part geometry, support, stock, wheel condition, thermal control, setup, and measurement. A process study should define the expected tolerance distribution.
Options may include grinding between centers, chucking, special arbors, center-drive arrangements, steady rests, and dedicated fixtures. Selection follows the part datums, drive torque, accessibility, distortion risk, and finished-surface protection.
In-process gauging is valuable when wheel wear, thermal drift, incoming stock, or long unattended runs could move size outside the required range. Gauge location and compensation logic must be compatible with the feature and cycle.
