Monarch VMC-2855QP VERTICAL MACHINING CENTER

Technical Description

This vertical CNC machining center is engineered for heavy-duty precision machining with a **60" x 26" worktable** capable of supporting workpieces weighing up to **3,250 lbs**. The machine features a **vertical spindle** offering dual taper sizes: standard **CT50** for robust, heavy machining tasks, and optional **CT40** for higher-speed, lighter operations. The spindle runs at a maximum of **6,000 RPM**, with an optional upgrade to **12,000 RPM**, powered by a **30 HP (30-minute rating) motor**, delivering strong cutting force and efficient performance. It uses an **Automatic Tool Changer (ATC)** with a base capacity of **24 tools**, expandable up to **32**, facilitating versatile and efficient machining setups. The system supports **3-axis machining** with optional 4-axis capability, providing precise and complex tool movements. Axis travels include **X-axis: 55"**, **Y-axis: 27.5"**, and **Z-axis feed rates and rapid traverse speeds of 276 IPM and 590 IPM**, respectively, ensuring quick and accurate positioning. The spindle tapers (CT40 and CT50) conform to ASME B5.50 standards, supporting rigid tool holding and optimal torque transmission for both fine and heavy machining. The overall design incorporates precision linear guideways and ball screws, resulting in high positional accuracy and repeatability, essential for producing intricate components with tight tolerances. This configuration supports machining operations ranging from milling, drilling, tapping to boring on large, heavy-duty workpieces with enhanced stability and tool life.
