What is knurling, and how many kinds of patterns are there?
The method of rolling out different patterns on the surface of the workpiece with a knurling knife is called knurling.
There are many kinds of knurled patterns, roughly straight, twill, and net patterns. Among them, the net patterns are diamond and square, that is, 30° and 45°. According to my country's national standard GB6403.3-86, the knurled pattern Calculated by modulus, there are four kinds of 0.2, 0.3, 0.4, 0.5, and its P value (distance of pattern teeth number, unit mm) is 0.2=0.628, 0.3=0.942, 0.4=1.257, 0.5=0.571. Usually the pattern has Metric and imperial systems, the P value of the imperial system is calculated according to the number of teeth per inch; the P value of the metric system is every 0.1 specification, that is, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 1.0, 1.2, 1.4, 1.6, etc.
