Data center & HPC – MQD Socket body
The MQD (Multi Quick Disconnect) socket body is a key component of compact liquid cooling connectors used in liquid cooling systems for AI data centers and High Performance Computing (HPC) applications.
MQD is a compact liquid cooling connector developed for use in space-constrained environments such as densely packed AI servers and GPU racks. It enables both space savings and highly reliable fluid connections.To ensure superior sealing performance, the socket body requires precision machining of internal diameters and sealing surfaces, as well as high concentricity and roundness. Corrosion-resistant materials such as stainless steel are often used, making consistent quality and high machining accuracy critical factors in overall product performance.
We provide a total machining solution through the optimal combination of tools, delivering both high productivity and stable machining performance for liquid cooling connector components requiring exceptional dimensional accuracy and superior surface quality.
Tooling concepts
- Internal turning and grooving solutions for high-precision sealing surface machining
- High rigidity tooling with through-coolant capability for stable stainless steel machining
- Exchangeable head tools and multi-corner inserts that reduce setup time and tooling costs
Featured process
Process 1: Internal turning
Benefits
- Specially designed for small-diameter internal machining, delivering high tool rigidity to suppress chatter and ensure stable machining.
- Two cutting edges per insert help reduce tooling costs.
- The DT4 grade features a thin TiAlN coating that minimizes heat-related tool damage and delivers extended tool life in internal machining applications where heat tends to build up.
- Adjustable tool overhang enables quick and easy cutting-edge positioning during corner indexing, reducing machine downtime and improving productivity.
- Through-coolant capability delivers coolant efficiently to the cutting edge for superior chip evacuation and longer tool life.
Process 2: External rough turning
Benefits
- The sharp YL chipbreaker combines low cutting forces with excellent chip control, making it ideal for small stainless steel parts.
- ST4 grade with advanced high-Al CrAlN coating resists wear, oxidation, and built-up edge, delivering extended tool life and outstanding surface quality.
- Quick-change head system minimizes setup time and maximizes machine uptime.
- Internal coolant delivery enhances edge cooling and chip evacuation for reliable, stable machining.
Process 3: External face grooving
Benefits
- Specially designed for automatic lathes and Swiss-type lathes, providing excellent accessibility for face grooving of small-diameter workpieces.
- The high-rigidity holder and clamping system suppress chatter and ensure stable dimensional accuracy.
- The four-corner insert design contributes to longer tool life and reduced tooling costs.
- The SH7025 grade features a TiCN and multilayer TiAlN coating, delivering excellent wear resistance and fracture resistance. Advanced coating technology suppresses built-up edge formation, maintaining stable dimensional accuracy even in stainless steel machining.
- The gold-colored coating makes it easy to identify edge damage and distinguish unused corners, even in machine tools and factory environments with limited lighting.
Process 4: Slotting
Benefits
- An exchangeable-head end mill system that supports a wide range of milling applications through combinations of various head geometries and shank types.
- The exchangeable-head design dramatically reduces machine downtime. Head replacement can be completed without tool presetting or protrusion adjustment, improving operational efficiency.
- The ER collet-integrated shank ensures stable and reliable machining performance.
Process 5: Deburring
Benefits
- The 2-flute design with a 30° helix angle provides excellent sharpness and efficient chip evacuation.
- The 30° helix geometry ensures stable cutting performance across a wide range of applications.
- The AH750 carbide substrate combined with a TiAlN coating delivers excellent wear resistance and stable machining performance. It is also suitable for machining high-hardness steels.
