Data center & HPC – UQD Plug body

Tooling concepts

• Optimal tools are selected to machine plug body-specific features, including high-precision OD and mating surfaces, deep-hole IDs, and cotter sections.
• Highly rigid tooling, optimized cutting edges, and suitable grades ensure consistent dimensional accuracy and excellent surface quality.
• Excellent chip control, coolant delivery, and exchangeable-head tooling systems combine stable machining with high productivity.

Process 1: Hole making

Benefits

• DrillMeister is an innovative head-changeable drill that combines the performance of a solid drill with the convenience of an indexable tool.
• A unique self-clamping system enables quick and easy head changes.
• No regrinding required, reducing regrinding costs and spare tool inventory for easier tool management.
• The DMP head features a 140° point angle for versatile hole making, with a sharp cutting edge preparation that delivers low cutting resistance and long tool life.

Process 2: External turning

Benefits

• Maximum depth of cut of 5.0 mm enables single-pass machining, significantly reducing cycle time while helping extend tool life through fewer machining passes.
• The dedicated TFX chipbreaker provides excellent chip control, ensuring stable external turning even under high-feed cutting conditions.
• ST4 grade with advanced high-Al CrAlN coating resists wear, oxidation, and built-up edge, delivering extended tool life and outstanding surface quality.

Process 3: Boring

Benefits

• Featuring a high-rigidity carbide shank, the tool suppresses deflection and chatter that are likely to occur in deep-hole machining, ensuring stable internal turning operations.
• The F1 chipbreaker, optimized for blind-hole applications, directs chips toward the hole entrance, preventing chip clogging and entanglement inside deep holes. This minimizes machining interruptions and insert failure caused by chip-related issues.
• Sharp-edge inserts provide excellent cutting sharpness with low cutting resistance, reducing chatter and enabling stable, high-quality internal turning.
• ST4 grade with advanced high-Al CrAlN coating resists wear, oxidation, and built-up edge, delivering extended tool life and outstanding surface quality.

Process 4: External grooving & threading

Benefits

• The head-exchange system allows setup changes with head replacement alone, while keeping the shank mounted on the machine—dramatically improving insert replacement and setup operations.
• Economical 4-corner design. Mounting a ground-grade insert in a unique 3-point clamp (proprietary pocket) achieves excellent repeatable cutting-edge positioning accuracy and clamp rigidity.
• The TCG insert for grooving features an optimized rake angle and edge preparation, delivering a well-balanced combination of sharpness and fracture resistance.
• The TCT insert for threading features a sharp, low-resistance cutting edge design that suppresses tearing and contributes to a consistently high-quality machined surface.
• The unique coolant delivery system supplies coolant from both the rake face and flank face sides directly to the cutting edge. It provides superior chip control and cooling performance, even in difficult-to-machine materials, ensuring stable and highly productive machining.

Process 5: Cotter milling

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 integrated structure of the ER collet and shank minimizes deflection at the clamping interface, delivering high tool rigidity. This enables a wide range of machining conditions, from heavy-duty cutting to high-precision finishing.
• Variable pitch and variable lead design suppresses chatter vibration, delivering excellent surface finish quality and high dimensional accuracy.

Process 6: External turning

Benefits

• The chipbreaker geometry, dedicated to ultra-low depth of cut and low feed machining at 0.05–0.3 mm, ensures reliable chip control even in finishing operations.
• The sharp edge and double positive geometry deliver low cutting resistance, suppressing burr formation and achieving a high-precision finished surface.
• ST4 grade with advanced high-Al CrAlN coating resists wear, oxidation, and built-up edge, delivering extended tool life and outstanding surface quality.
