Models and Options
Multiple models are available depending on the combination of grit type, grain size, hardness, and structure number. Customers can select the optimal configuration for their specific material and finish requirements.
Materials and Structure
The wheel is composed of aluminum oxide abrasives (brown fused alumina or white fused alumina) bonded with a vitrified ceramic bond. The open or dense structure (numbers 0-14) can be adjusted to control porosity, improving coolant flow and chip clearance.
Applications
Centerless grinding wheels are used for cylindrical parts such as bearings, rollers, pins, and shafts. They are widely applied in manufacturing industries for high-volume production and precision finishing.
Customization
Custom specifications are available upon request, including special grain types, hardness grades, and dimensions up to the maximum listed. Contact our engineering team to tailor the wheel to your exact needs.
