Clearance angle grinding wheels

Grinding clearance angles on the cutting edge of a tool reduces the contact area between the tool and the workpiece during drilling or milling processes. One or two clearance angles are usually ground on the face. Up to two clearance angles/clearances can be produced on the circumference; on some tools, these take the form of radial clearance grinding. For grinding clearance angles 11V9 cup wheels or similar geometries are typically used.

Clearance angle refers to the angle between the grinding wheel surface and the workpiece being ground. It is an important parameter in grinding operations and affects the cutting action, tool life, and surface finish of the work-piece. The clearance angle allows the cutting edges of the grinding wheel to penetrate the work-piece and remove material effectively.

The specific clearance angle for grinding wheels can vary depending on the type of material being ground and the desired outcome. In general, softer materials require larger clearance angles, while harder materials may require smaller clearance angles.

When selecting a grinding wheel for a particular application, it’s important to consider the manufacturer’s recommendations and guidelines. They often provide information on the appropriate clearance angles for their grinding wheels based on the intended use.

It’s worth noting that clearance angles can also vary depending on the type and design of the grinding machine being used. Different machines may have specific requirements for clearance angles to ensure optimal performance and tool life.
