The Shigiya GAC-20 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 20-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-20 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-20 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-20 can hold the required size, roundness, cylindricity, and surface finish through production.
GAC-20 is most valuable when its cnc angular cylindrical grinder configuration directly addresses the part’s size, feature access, work support, or production sequence. Selection should be based on a documented process advantage rather than model familiarity.
Confirm which surfaces require straight, angular, internal, face, or specialty access; then check wheel diameter, width, swivel or approach, guard clearance, dressing location, and interference with workholding.
Yes, but hardened steel, stainless, carbide, coatings, and other materials can require different abrasives, bonds, speeds, coolant, filtration, dress tools, and stock allowances. Cross-contamination and changeover should also be considered.
Common contributors include thermal change, wheel wear, dress variation, part deflection, center condition, coolant temperature, gauge repeatability, stock variation, and inconsistent spark-out. Process data should identify the dominant source before compensation is changed.
Foundation, leveling, vibration from nearby equipment, ambient temperature, power, air, coolant system, mist collection, material handling, and maintenance access all affect long-term performance and should be reviewed before delivery.
