Tired of large fluctuations in internal bore precision and insufficient service life? Try this micron-level stable machining solution.
With the explosive growth in demand for AI computing power, heat dissipation technologies for computer data centers have witnessed profound changes. Liquid cooling systems have quickly gained wide popularity in the industry thanks to their excellent heat dissipation efficiency. Behind this technological upgrade, the valve sleeve, a seemingly small yet indispensable component, has gradually become a core technical highlight in the field of precision manufacturing.
In AI liquid cooling systems, valve sleeves are used to precisely regulate the flow rate and pressure of cooling fluid, whose performance directly affects the stability of the entire heat dissipation system. The profile tolerance of inner holes on valve sleeves needs to reach micron-level precision, with the machining error controlled within a fraction of the diameter of a human hair. Such stringent manufacturing standards have made valve sleeves notoriously difficult-to-process products in the liquid cooling component industry chain.
Taking a large manufacturer of core liquid cooling system components in South China as an example, the company faced multiple difficulties in valve sleeve machining. Adhering to the long-term philosophy of win-win cooperation, joint development and customer-oriented service, ACHTECK continuously optimized tool materials, structural designs and machining parameters, effectively solved production difficulties for the client and won sincere recognition and trust.
Challenge 1：AI liquid cooling components are made of special materials with small finishing allowance, leading to short service life of conventional cutting tools.
ACHTECK Solution：
In accordance with workpiece material properties, we optimized insert substrates and coatings, raising the unstable tool service life from 100 to 300 pieces to a steady level of around 800 pieces. The overall machining efficiency and tool service life have increased by more than 200%.

Challenge 2：Strict precision requirements are imposed on inner hole finish machining of valve sleeves, with the profile tolerance limited within 5 microns, accompanied by obvious dimensional fluctuation.
ACHTECK Solution：
To solve precision tolerance problems, ACHTECK developed and launched the ASI series tools, which adopt rear inclined surface positioning structure to greatly improve tool positioning accuracy.
Challenge 3：Abnormal fluctuation of tool service life occurs during valve sleeve machining.
ACHTECK Solution：
On-site tests and tracking analysis proved that center height deviation is the major influencing factor. The abnormal fluctuation issue has been completely resolved through parameter adjustment and adoption of matching sleeves.
Backed by advanced technical strength and consistent follow-up services, ACHTECK tools maintain outstanding wear resistance during high-speed cutting, ensuring stable compliance of inner hole precision for every valve sleeve in mass production. This not only greatly reduces tool replacement frequency and improves overall production line efficiency, but also provides solid and reliable manufacturing support for the large-scale commercial application of AI liquid cooling systems.
