The Application of Precision Boring Cutters and Internal Threading Tools in the AI Server Industry

Precision cutting tool technology can meet the high standard of being burr-free under 30x magnification inspection, effectively preventing issues such as cooling system leaks from the AI server's liquid cooling connectors used for chip systems.

What is an AI server liquid cooling connector?

AI server liquid cooling connectors are a very popular technological field right now. Simply put, they are critical components used in AI server liquid cooling systems to connect various heat dissipation elements, such as CPU/GPU water blocks, radiators, and tubing.

As the demand for AI computing continues to grow, high-end GPUs launched by companies like NVIDIA and AMD consume over 700W, or even more than a kilowatt, of power. Traditional air cooling can no longer handle such high heat loads, making water cooling (liquid cooling) an inevitable trend.

Although an AI server liquid cooling connector is a small part, it is an indispensable component of the entire high-performance computing cooling system.

Why are "boring cutters and internal threading tools" so important here?

A water cooling system is composed of cold plates, tubing, radiators, pumps, and other components. The liquid cooling connector is the critical part responsible for connecting these tubes and components precisely and without any leaks.

The liquid cooling connector is not a simple part. It requires extremely precise machining on metals (such as brass, stainless steel, and aluminum alloys). This machining process relies entirely on high-performance "boring cutters and internal threading tools."

There are several key manufacturing requirements involving boring cutters and internal threading tools:

High Precision: The tolerance of the connector needs to be controlled at the micrometer (µm) level. Any dimensional deviation can lead to an improper seal, causing leaks under the high-pressure circulation of the coolant. In a data center—where space is precious, power is dense, and equipment is expensive—a single drop of leaking water can cause millions of dollars in damages. To machine such precise dimensions, top-tier precision boring cutters and internal threading tools must be used.

Complex Geometries: To ensure smooth coolant flow with low resistance, the inside of the connector often has complex curved and channel designs. This requires the use of special tools like form milling cutters and ball-nose end mills to machine the complex internal structure in a single operation.

Perfect Surface Finish: The surfaces that come into contact with O-rings or other sealing components must be as smooth as a mirror to ensure airtight and liquid-tight seals. This requires using extremely high-precision reamers, boring tools, or finishing mills for the final finishing process.

Thread Reliability: The threads on the connector are used for fastening and securing. The thread form, depth, and precision directly affect the connection's strength and sealing capability. This requires high-quality taps (threading tools) to ensure every thread is flawless.

In summary, high-quality liquid cooling connectors can only be manufactured using high-precision CNC machine tools and high-performance, long-lasting, high-precision "boring cutters and internal threading tools."

Without advanced boring cutter and internal threading tool technology, it is impossible to mass-produce precision liquid cooling connectors that meet strict requirements. Without reliable liquid cooling connectors, the heat dissipation problem of AI servers cannot be solved, and their powerful computing capabilities cannot be stably utilized.

Amid the AI wave, it's not just chip manufacturers and server assembly plants, but also high-end products in related fields such as precision machinery, cutting tools, and materials that are receiving significant market attention.
