Edited words: Generally speaking, drills with a diameter smaller than 3.175 can be called micro drills. I believe everyone is familiar with micro-drilling. Some time ago, the key to the melt-blown die head was the processing of micro-holes. Its hole diameter ranged from Ф0.1-Ф0.3mm, and the ratio of depth to diameter exceeded 10, which made it difficult to process. However, have you ever thought about how such a small hole is processed? So how are the tiny drill bits made? What is it processed out of?

So, what equipment can be used to process the small holes on the spinneret of the mask meltblown cloth? Let’s take a look at the whole process of making the spinneret of Kason’s micro-hole processing in Japan. The processing of various holes is mentioned:

The process of producing micro-drills on a tool grinder
In the development of global tool grinding machines, Makino Seiki of Japan has always played a leading role. Makino Seiki's high-precision CNC small-diameter tool grinder SS7 can grind drills as small as Ф0.05mm. Let's learn about the process of grinding and producing micro-drills using a Japanese Makino Seiki tool grinder through a video:
