The Shigiya GAC-30 is a versatile angular cylindrical grinder designed for precision grinding of complex geometries and angled surfaces on larger workpieces. It delivers consistent accuracy through a rigid machine structure, precise multi-axis control, and stable thermal performance over extended run times. As a result, the GAC-30 supports reliable production while maintaining tight tolerances and repeatable part quality.
The GAC-30 is a space-saving compact CNC angular grinder built for small parts that demand tight tolerances. Despite its size, it delivers exceptional performance. Its strong structure supports stability and repeatability during high-volume production. Because this compact CNC angular grinder is built for tight areas, it fits easily into lean manufacturing cells. It offers consistent accuracy while saving space, making it ideal for shops focused on productivity.
The GAC-30 stands out as a high-precision cylindrical grinding solution for industries like medical, aerospace, and electronics. Its rigid design and responsive controls allow operators to hold strict tolerances across complex part profiles. Additionally, this high-precision cylindrical grinding machine handles delicate components without sacrificing speed. With stable grinding and accurate feed, it produces flawless surfaces, even on micro-diameter parts.
Unlike traditional setups, the GAC-30 supports simultaneous O.D. and face grinding. This capability reduces the number of setups and increases output. While one grinding wheel works the outer diameter, another handles the face—both at the same time. This method shortens cycle times and improves part consistency. When performing simultaneous O.D. and face grinding, manufacturers finish more parts with fewer errors. As a result, they deliver jobs faster and at a lower cost.
The GAC-30 integrates smoothly into automated grinding solutions. With CNC control and robot compatibility, it fits easily into unmanned grinding cells. As automation becomes more common, this machine helps teams run overnight shifts without extra labor. Machine Shops benefit from better consistency and fewer bottlenecks. These automated grinding solutions increase throughput while maintaining strict part quality.
As reliable precision machining equipment, the GAC-30 gives operators full control over small-part production. From surgical pins to small shafts, it handles every detail with care. This small parts grinding machine is ideal for shops that need to combine tight tolerances with high-speed runs. It minimizes error and maximizes output, giving manufacturers a lasting edge in precision work.

The Shigiya GAC-30 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 GAC-30 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 GAC-30 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 GAC-30 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.
