Yong Ju Precision Technology Co. Ltd. 4 STAR FD-4270 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust table measuring 275.6 inches in length by 165.4 inches in width, providing extensive work support for large or complex parts. The machine is equipped with a vertical spindle utilizing a CT-50 taper, ensuring high rigidity and precision for demanding machining tasks. The spindle delivers a maximum speed of 6,000 RPM, with an optional top speed of 4,500 RPM, and offers a 30-minute power rating of 35 HP, extendable to 40 HP for enhanced performance. Tooling is managed by an automatic tool changer (ATC) with a standard capacity of 32 tools, expandable to 120 tools for increased flexibility. The machine operates on three primary axes (X, Y, Z), with the option to add a fourth axis for advanced contouring and complex part production. Rapid traverse rates and maximum feed rates are engineered for high-speed, efficient material removal, though specific values for X, Y, and Z travel and feed rates are not provided. The absence of a support index table or rotary table maintains a focus on straightforward, high-capacity milling operations. This machining center is designed for heavy-duty applications, combining a large work envelope, powerful spindle, and versatile tooling system to deliver reliable, high-precision results in industrial environments.
