[0002] Knurling is a mechanical process of rolling patterns on the handle or other working surface of metal products, mainly for anti-slip and aesthetic purposes. According to the processing technology, knurling tools can be divided into extrusion knurling tools, clamping knurling tools and cutting knurling tools. If we look at the number of knurling wheels, they can be divided into single-wheel knurling tools, double-wheel knurling tools, three-wheel knurling tools, and even six-wheel knurling tools. In addition, according to the different patterns, knurling tools can also be divided into straight knurling tools and mesh knurling tools.
