Shock: how to realize the drilling process with a diameter of only 0.01mm!!!

The level of machinery manufacturing in a country is usually an important symbol to measure whether a country's manufacturing industry is developed, and the field of machinery manufacturing has the highest difficulty and technical content in extremely micro processing and super large processing, which is also the competitive highland of high-end manufacturing in various countries!

Micromachining is usually used in medical, aerospace, communication, optoelectronics and other fields. It is also a common processing technology!

Micro machining or micro small part machining refers to the processing of small workpieces, which is usually used in the field of medical devices and electronics. Parts produced by micro machining process usually need to be observed by microscope. Micro machining is generally carried out in workshops specializing in micro parts or precision machining.

It is reported that the micro machining drill bit of a Japanese company can realize micro machining with a diameter of 0.03 mm or even 0.01 mm. The factory was established in 1976, initially to continue the business of Xiaoshan diamond company in Japan, and began to manufacture and export audio parts at the same time. In 1996, Cebu microelectronics Inc. (CMI) was established in the export processing zone of Cebu Island, Philippines, and began to manufacture high-frequency components and ultra precision components. In February 2020, with the business expansion, we set up an office in China to develop business for the purpose of selling semiconductor products.

This company specializes in "drilling" of small diameter and deep holes. Compared with electrical discharge machining and laser machining, drilling will not bring burden to the workpiece, and can realize high-precision and clean opening on the inner surface. Not only the drilling of 0.03mm, they even completed the ultra microporous processing of 0.01mm and reached 10 times the diameter (the depth is 10 times the diameter, editor's note).

Case: super long front dispensing needle beyond the processing limit

At present, for the processing of the front-end length of precision dispensing needle, the inner diameter aspect ratio is 1:10, which is the limit of processing. The front-end ultra long dispensing needle of this Japanese company has realized the inner diameter aspect ratio of 1:24, subverting the common sense of processing technology.

For a long time, the biggest feature of the precision dispensing needle is the use of the internal seamless conical design, and the cutting process adopts the integrated cutting form, which successfully solves the problem of internal material blockage. Even the polishing process is adopted at the front end, which successfully solves the problems of material creeping and wire drawing, so it can be realized according to the needs of customers, and the precise and stable dispensing in small gaps can be successfully realized.

NIMS: nano processing that can engrave characters on mites

The Japanese Institute for material research (NIMS) showed a video of ultra micro machining technology. They can engrave words on the mouth of mites. The font length is less than 2 microns, smaller than E. coli. This technology can be used in the development of electronic components and the processing of nano materials.

Kono production Institute: it can produce 0.03mm surgical needle

How thin can the surgical needle be - 0.03mm in diameter and 0.8mm in length. The suture on the surgical needle is too thin to be seen by the naked eye, with a diameter of only 0.012mm.

The application of this 0.03mm ultra-fine surgical needle in clinic has brought revolutionary changes to the field of regenerative transplantation, realized previously difficult operations, such as the suture of blood vessels, lymphatic vessels and nerves below 0.5mm, and achieved great results in the regeneration of severed fingers in infants.

The development of 0.03mm diameter surgical needle is difficult. The material used for the surgical needle Precision dispensing needle is special stainless steel. In the whole production process, the stainless steel needs to be stretched and cut, and the top needs to be sharpened, bent, ground and sharpened. However, the surgical needle is so small that although it uses metal materials, it should be made as light as hairspring like cotton fibers. The whole processing process requires skilled employees to complete it manually under the microscope, and the required special tools and instruments are independently developed by the employees of Kono production Institute.

The headquarters and plant of Kono production office are located in Kawaguchi, Chiba Prefecture, on the outskirts of Tokyo. The company has developed the world's smallest microsurgical needle for suturing micro blood vessels and nerves. Now it is famous all over the world with the trademark of "crownjun".
