Knurling is the mechanical process of rolling a pattern into the knobs or other working surfaces of metal products, often used to provide better grip or texture on objects such as handles, knobs, or shafts. The knurling process creates a raised pattern that not only enhances grip but also enhances the aesthetics of the object. Many parts will have knurling added to the surface. This article will walk you through the basics of the process.
1.What is knurling?
The method of using a knurling tool to roll out straight or reticulated lines on the surface of a workpiece is called knurling. There are also knurling tools that consist of a set of rollers or wheels with specially shaped teeth pressed into the surface of the material.
2.How is knurling done?
The basic principle of knurling is the surface extrusion process, or the cutting process. The points that need attention are usually the fit of knurling tool, knurling wheel and workpiece. Knurling processing requires accurate control of the linear speed and feed rate of the lathe during processing, which requires a little patience and experience.
In the lathe knurling process, if the workpiece material is stainless steel, a cutting knurling knife is usually used; if the workpiece is relatively small, a pincer knurling knife is used; Knives; choose a suitable tool, and the final knurling gap will be small and high in hardness.
3.What types of knurling are there?
There are many types of knurling, and there are many further changes according to the type, but the types of knurling on the market are mainly conventional.
According to the classification of knurling texture, it can be divided into the following 6 types: straight knurling, left and right diagonal knurling, convex net knurling, concave net knurling, convex cross knurling, concave cross knurling, of which straight grain The two most common knurling textures are knurling and reticulation (including convex and concave).
According to the surface classification of knurling, it can be divided into the following 7 types: cylindrical surface knurling, cylindrical end knurling, flat knurling, cylindrical inner hole knurling, conical knurling, convex arc surface knurling, concave arc surface knurling
According to the classification of knurling process, it can be divided into the following 6 types: single-wheel extrusion knurling (straight grain, reticulated pattern), double-wheel extruded knurling (reticulated pattern), single-wheel cutting knurling (straight grain), double Wheel cutting knurling (reticulated), pincer knurling (straight, reticulated), three-wheel knurling (straight, reticulated)
4.What is the function of knurling?
One of the main functions of the knurling is to improve grip. This is especially important in applications where objects are slippery or difficult to grip. Knurling creates a rough surface that allows the user to apply greater force or torque without slipping. The risk of accidents can be reduced and safety and productivity can be significantly improved.
Another important function of knurling is to enhance the aesthetics of an object and enhance its visual appeal.
Additionally, by creating a rough surface, knurling can increase the friction between two surfaces, thereby improving the effectiveness of a seal or joint. Knurling can also be used to create a locking mechanism where ridges on one surface interlock with grooves on the other, creating a secure and secure connection.
