Recently, it independently designed and successfully manufactured extremely small tungsten steel milling cutters with a diameter of at least 0.01 mm. Machine processing.
As we all know, tungsten steel milling cutter is a rotary cutter with one or more teeth, and its fineness is an important reference index in the manufacturing and processing industry. This extremely small diameter milling cutter, which is about 1/8 of the diameter of a human hair, milled 56 Chinese characters on a grain of rice and 7 letters on a single hair.
This breakthrough will help improve product quality in many fields such as my country's electronic information industry, medical device manufacturing and inspection, and will also indirectly benefit micro-miniature processing tools a lot.
