Introduction
Knurls have found wide applications in different industries due to their integral role in imparting a grip to the CNC turned components. A precision-cut diamond pattern or straight linear knurl onto your components not only transforms the aesthetics of the part but also significantly improves its functionality. These gains make a strong case for the understanding of knurling tools in depth, as we will do in this blog.
Understanding Knurling and the Knurling Tool
Primarily used in metalworking, knurling is a manufacturing process where a pattern of straight, angled, or crossed lines is rolled into the surface of a part. The patterns enhance the grip and sometimes to accommodate more surface area on the component. In CNC turning, a specific tool called the 'knurling tool' is used to perform this task.
Typically, a knurling tool is annotated by two diametrically opposed hardened steel wheels with teeth that specifically cut the patterns into the material. The wheels could have either straight, angled, or crossed teeth, depending on the type of pattern required on the CNC turned part.
The Magic Behind CNC Turning and Knurling
CNC Turning, an integral part of manufacturing in multiple industries like aerospace, automotive, electronics, and more, requires the addition of textures to components for improving functionality. CNC machines deploy knurling tools to add these surface enhancements effectively and quickly.
Here, the knurling tool is held stationary and advanced into the workpiece, while the CNC turned part rotates. Adjustments can be made as desired, depending on the depth of the pattern. By carefully controlling these parameters, one can achieve the perfect knurled surface that meets precise engineering requirements.
Factors to Consider While Selecting a Knurling Tool
When selecting a knurling tool, the top-most consideration needs to be the desired pattern. Straight knurls can provide a linear pattern, and diagonal knurls offer a diamond-like effect, while a cross knurl can make a cross-hatch pattern. Other factors like material, dimensions, pitch, and tooth shape of the workpiece also influence the selection.
The knurling tool holder type plays a vital role as well. You can choose between Scissor-Type Holders, Cut-Type Holders, and Form-Type Holders, each having their pros and cons.
Achieving Desired Results with the Knurling Tool and CNC Turning
Understanding the full potential of the knurling tool and CNC turning requires some practice. Mastery comes with a profound understanding of the equipment and adequate industry experience. Utilizing its maximum potential can lead to precision-manufactured parts and also contribute to cost-effectiveness by extending tool life.
In summary, a knurling tool in a CNC Turning setup can be an extremely valuable addition to your manufacturing processes. It offers decoration, functionality, identification, and increased surface area to the CNC turned parts. If used carefully and effectively, knurling can add significant value to the end product while meeting expectations set by various engineering specifications.
Despite the influence of advanced manufacturing techniques such as 3D Printing and Additive Manufacturing, CNC turning holds its own, thanks to processes like knurling. As we venture further into the realm of machine manufacturing, tools like these will only strengthen their presence and relevance.
