Inner Diameter (ID) grinding, synonymous with internal grinding, inside diameter grinding, and bore grinding, represents a meticulous machining process where the material is precisely removed from the inside diameter of a cylindrical or conical workpiece. This operation intricately shapes the internal surface of a cylindrical workpiece, which rotates as an abrasive tool machines its inner circumferential surface in the opposite direction.
The Process of ID Grinding
The ID grinding process utilizes an internal grinding machine equipped with a grinding wheel that is instrumental in removing the final stock to a finish dimension and surface finish. The machine and the grinding wheel must be up to the task, capable of handling the precision and intricacies of the process.
The grinding wheel is usually made of aluminum oxide abrasives, known for their hardness and durability. The process also requires multiple work-holding options to secure the workpiece during grinding.
Inner Diameter Grinding Capabilities
With its ability to offer precision and tight tolerance control, ID grinding is an optimal choice for machining intricate aerospace assemblies and components. By improving the quality of the finished product, ID grinding plays a significant role in enhancing production operations.
Notably, ID grinding can manage parts from .250" to 20" inside or outside diameters by 14 inches deep, perfecting faces, tapers, and radii with exceptional precision. This process also excels in grinding multiple features of a part on one chucking, leading to fewer setups, diminished wasted time in handling parts, and more accurate runout, perpendicularity, and concentricity.
To meet these demanding requirements, state-of-the-art grinding machines, such as the Okamoto IGM-2M, are deployed in ID grinding. These machines are engineered to withstand rigorous high-volume production while upholding exceptional accuracy and dimensional repeatability.
Applications of Inner Diameter Grinding
ID grinding finds extensive use across diverse components, including bearings and bushings, aerospace components, shims, pins, and rods. Specialized aerospace grinding machines, such as the Aerospace centerless grinding machine, Aerospace cylindrical grinding machine, Aerospace shaft grinding machine, Aerospace surface grinding machine, and Aerospace vertical grinding machine, are harnessed to offer the highest quality aerospace grinding services.
Some of the common applications of ID grinding include:
- Bearings and bushings
- Aerospace components
- Shims
- Pins
- Rods
Materials and Tolerances
The materials that can be processed through ID grinding span from metals to ceramics, composites, plastics, and rubber, with finishes including hard chrome and coatings. The process can accommodate inside part diameters of .200″ to 36″ and outside part diameters of up to 48″. The highest tolerance achievable is up to +/-.0002″, underscoring impressive precision.
Quality Assurance in ID Grinding
Rigorous quality control standards are integral to the ID grinding process. Procedures encompass visual inspections, dimensional measurements, hardness testing, and numerous other tests to ensure components meet all required specifications. Full documentation of the grinding process is provided for complete accuracy and quality control, often complying with ISO and Mil-Spec standards.
