Knurling is a mechanical process used in engineering and metalworking to create a pattern of tiny ridges or raised points on the surface of a material, typically metal. These ridges, known as knurls, serve various functional purposes such as improving grip, facilitating positioning or alignment, preventing slippage, or enhancing the overall aesthetic appeal of the object.
The process of knurling involves pressing a specialized tool called a knurling wheel against the surface of the material, causing it to deform and create the desired pattern. Knurling is performed using lathes or similar machines, where the material rotates against the stationary knurling tool.
Knurling can take different forms, such as straight, diamond, or diagonal patterns, depending on the shape and configuration of the knurling wheel. The dimensions of the knurls, including their height, width, and pitch, can also vary to suit specific design requirements and intended applications.
The primary benefit of knurling is the improved grip it provides. By increasing the surface area between the material and the user's hand, knurling greatly enhances the ability to hold and manipulate objects securely, even in wet or slippery conditions. This makes knurled surfaces particularly useful on handles, knobs, or other components that require manual operation or adjustment.
In summary, knurling is a mechanical process used to create a pattern of ridges on the surface of a material, primarily to enhance grip, improve alignment, prevent slippage, or add visual appeal to mechanical components or tools.
