UV Series 5-Axis CNC Mill | Trunnion Design for Precision Machining

EUMASEIKI launches the new UV Series 5-axis CNC milling machine, built with an integrated trunnion rotary table to help job shops and precision manufacturers improve efficiency and part quality. This machine is designed for real production environments, focusing on stability, ease of use, and reliable performance for complex parts.

The UV Series comes with a heavy-duty trunnion table that supports a rotation range of -110° to +110°. This wide tilting movement gives the machine strong undercut machining ability, which is difficult to achieve with standard 3-axis or limited 5-axis equipment. Manufacturers working on molds, aerospace parts, and mechanical components can now finish deep undercut features and complex surfaces in one setup, without repeated re-clamping.
Fewer setups mean fewer positioning errors. Each time a part is removed and re-fixed, small deviations can add up and affect final accuracy. The UV Series reduces this risk by completing multi-face machining in a single operation. This is especially valuable for industries that require tight tolerances, such as automotive, medical equipment, and precision engineering.
Compared with swivel head 5-axis machines, the UV Series offers a larger effective working volume. Since the trunnion design does not use a spindle-mounted swivel head, it saves valuable space above the workpiece. This allows manufacturers to process larger parts more freely, and reduces the need for complicated fixtures. For job shops handling various part sizes, this flexibility directly improves productivity and lowers overall operating costs.
The UV Series is also built for heavy cutting tasks. Its stationary belt-driven spindle provides higher torque at low RPMs, making it suitable for hard materials, deep cuts, and high-volume material removal. Even under continuous heavy cutting, the machine maintains stable performance and consistent precision. This helps reduce tool wear, minimize scrap rates, and extend service life in daily production.
For shops currently using 3-axis machines, upgrading to 5-axis can be challenging. The UV Series solves this problem with its user-friendly trunnion structure. The machine follows a linear machining logic similar to 3-axis operations, so existing operators can adapt quickly without long training periods. Shops can smoothly add 5-sided machining capabilities, reduce setup time, and increase output without major workflow changes.
EUMASEIKI focuses on designing and building CNC machining centers that balance precision, durability, and practical value. The UV Series is developed for industries including aerospace, automotive, mold & die, and general engineering. Every part of the machine is constructed to support long-term, reliable operation in busy production environments.
Whether you are expanding your machining capacity, replacing old equipment, or moving into more complex part production, the UV Series provides a practical and stable solution. EUMASEIKI also offers customized configurations to match different application requirements, ensuring the machine fits your actual production needs.
