Double Sides Recessed Grinding Wheels
Description of Type 7 Grinding Wheel
Double recessed grinding wheels feature grooves on both sides and are widely used in external cylindrical grinding, tool sharpening, and centerless grinding processes.
Their double-concave design provides clearance for spindle end faces, flanges, and fastening nuts during installation, ensuring smooth and interference-free operation.
As a result, they enable high-precision and high-efficiency machining of both metal and non-metal materials.

Applications of Vitrified Grinding Wheels
- Tool and Cutter Processing
Widely used for precision sharpening and form grinding of various complex cutting tools, such as milling cutters, reamers, and drill bits. - Precision Mechanical Parts
Suitable for precision cylindrical grinding of metal components including bearing rings, gears, nozzles, and turbine blades. - Centerless Grinding Applications
Commonly used as the grinding wheel or regulating wheel in centerless grinding machines, enabling high-efficiency and mass-production cylindrical grinding. - Non-metal Material Processing
Suitable for grinding, dressing, and polishing of hard and brittle materials such as glass, ceramics, and stone.

Advantages of Industrial Grinding Wheel
- Special Recessed Structure
The double recessed grinding wheel design provides additional clearance for mounting large flanges, preventing machine interference during operation. - High Precision
Maintains excellent geometric stability, making it suitable for ultra-precision grinding applications. - Wide Abrasive Material Selection
Depending on processing requirements, the grinding wheel can be produced with conventional abrasives such as aluminum oxide and silicon carbide, or superabrasives such as diamond and CBN (Cubic Boron Nitride).
