A lathe knurling tool is primarily used to create a textured surface on a workpiece, typically made of metal. This process, known as knurling, serves multiple functions. Firstly, it enhances grip by adding ridges to the surface, making it easier to handle or manipulate the workpiece. This is particularly useful for components like handles on tools or knobs on machinery where a secure grip is essential. Secondly, knurling can serve decorative purposes, adding visual interest to the finished product. Additionally, in industrial settings, knurling is sometimes used for identification purposes, providing a distinctive texture that helps differentiate between similar parts. In operation, the knurling tool is mounted on the lathe's tool post and pressed against the rotating workpiece to imprint the desired pattern onto its surface. Different knurling patterns, such as straight, diamond, or diagonal, can be achieved by using various knurling wheels or adjusting the tool setup accordingly.
