Generally, there are various knurling patterns on the interior buttons of luxury cars to enhance the touch texture and visual aesthetics, especially the cross-shaped knurling of various control knobs on the car.
In particular, the electronic rotary shift lever, this kind of shifting form is very unique, and many cars are currently equipped with this. But luxury cars will add more knurled elements to the details to enhance the texture and luxury.
There are also some commonly used rotary buttons with knurled patterns, which are used to increase the friction area and play a non-slip effect. There will also be quite good damping feel feedback on high-end cars.
First of all, this kind of cross knurling pattern is particularly delicate and small, and the requirements for the knurling pattern are particularly high, the teeth must be clearly visible, the finish is high, and the number of teeth is required to be stable.

What is knurling? Why should it be knurled?
Knurling is a mechanical process of rolling patterns on the knobs of metal products or other working surfaces. It mainly rolls the surface of the workpiece with a knurling knife to form straight or reticulated patterns. This approach is mainly to prevent slippage. Moreover, after the workpiece is knurled, it can increase the beauty and easy to hold, and is often used for the outer surface processing of parts such as micrometer casings and winch wrenches.
There are many kinds of knurling patterns, roughly three kinds: straight, twill, and net. Among them, there are rhombus and square patterns, that is, 30° and 45°.
What are the precautions for knurling?
- When starting rolling, it is necessary to use a large pressure to feed the knife, so that the workpiece can be carved with a deeper pattern, otherwise it is easy to produce random patterns.
- In order to reduce the radial pressure at the beginning of rolling, 1/2~1/3 of the width of the roller surface can be in contact with the workpiece. In this way, the knurling tool can be easily pressed into the surface of the workpiece, and after the knurling meets the requirements of the workpiece after parking inspection, the tool can be moved longitudinally. Repeat rolling 1 to 3 times until the pattern protrudes.
- When knurling, the cutting speed should be reduced, generally 5~10m/min. Select a larger longitudinal feed, generally 0.3~0.6mm/r.
- When knurling, it is also necessary to pour cutting oil to lubricate the roller, and often cut out the cutting produced by the rolling wheel.
