The Shigiya SG-38B is a special-purpose cylindrical grinding system for production components requiring a dedicated grinding sequence and application-specific workholding. 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 SG-38B is engineered around its defined component family rather than a general job-shop envelope. Wheel configuration, work support, loading, dressing, gauging, and cycle control should be verified from the production specification. 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 SG-38B include:
Axis control and wheel motion are developed around the required non-round or dedicated feature rather than a general cylindrical cycle.
Locating, drive, support, and in-process measurement must be engineered around the exact part family and production tolerance.
Abrasive type, grade, bond, wheel dimensions, dress form, and dressing interval must be matched to material, stock allowance, finish, and cycle time. The SG-38B 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 SG-38B can hold the required size, roundness, cylindricity, and surface finish through production.
SG-38B is most valuable when its special-purpose cylindrical grinding system 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.
