U400

5-Axis High-Speed Machining Center

High Speed and Outstanding Surface Finish

The Takumi U Series 5-axis, double-column machining centers are designed for high-precision finishing of parts of all sizes, especially for die/mold, aerospace, and medical applications. The U Series has an extremely robust structure that ensures enough rigidity to perform roughing and has the speed and acceleration for finishing.

• One-piece casting absorbs the thrust forces of high rapids and fast cutting feeds.
• One-piece, double-column design increases rigidity, enabling higher cutting feeds while maintaining superior part finish.
• Ladder design of cross rails increases rigidity and eliminates head deflection.
• Over 35 components are hand scraped for fit.
• Roller-type linear ways support faster feedrates, higher rigidity, and smoother linear motion due to larger contact area compared to ball-type linear rails.
• Large-diameter, pre-loaded and pre-tensioned ballscrews with fine pitch for accurate motion control.
• U400 has 15000-rpm, Big Plus®, CAT 40, motorized, inline spindle;
• Equipped with the latest Heidenhein TNC 640 control.
