ATRUMP E422 VERTICAL MACHINING CENTER

Technical Description

This CNC vertical machining center features a **48.8" x 18" table** capable of supporting workpieces up to **2,000 lbs**, with optional support for an index or rotary table. The spindle is a **#40 taper** oriented vertically, delivering a standard top speed of **6,000 RPM**, upgradeable to **8,000 RPM** with an optional 15.00 HP motor (standard 10.00 HP, 30-minute rating). The tool carrier is armless and houses **16 tools**, with a tool change time of **9 seconds** and no chip-to-chip delay, supporting efficient multi-tool operations. It operates primarily on **3 axes (X, Y, Z)** with an optional 4th axis. The travel along the X-axis is **41.7"**, Y-axis **22"**, and Z-axis **24"**, each capable of a max feed rate of **160 IPM** and rapid traverse at **320 IPM**. The rotary B-axis provides continuous 360° rotation for compound machining capabilities. This machine's construction and specifications are designed to deliver high rigidity and precision for complex machining tasks, suitable for heavy, large-format parts and tooling applications. The design supports high-speed spindle operations and rapid tool changes to optimize cutting efficiency and throughput, compatible with high-performance CNC controls typical in modern milling environments. Optional rotary and index tables expand versatility for 4-axis or 5-axis machining applications. This configuration is ideal for demanding manufacturing requiring robust load capacity and precise multi-tool integration.
