DN Solutions DNM 350 / 5AX VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a **13.8" x 13.8" table size** with a maximum workpiece weight capacity of **551 lbs**, suitable for precision milling tasks. It is equipped with a **vertical spindle** using the advanced **Big Plus #40 taper system**, offering increased tool rigidity through simultaneous contact of the spindle taper and face, reducing deflection and improving machining accuracy and surface finish. The spindle delivers a top speed of **12,000 RPM** with a robust power output of **24.66 HP (30-minute rating)**, with an optional upgrade to **29.5 HP**, enabling heavy-duty and high-speed cutting operations. The machine supports a compact **30-tool Automatic Tool Changer (ATC)**, with an optional extension to 60 tools, and fast tool change times of approximately **1.3 seconds** for tool-to-tool and **3.7 seconds** chip-to-chip. It has a **5-axis configuration** (X, Y, Z linear axes plus an A rotary axis), with travels of **15.7" (X), 25.8" (Y), 19.7" (Z)**, and a rotary axis of **150°**, providing versatile multi-axis machining capabilities. Maximum feed rates for linear axes reach **590 inches per minute**, with rapid traverses up to **1,417 IPM**, promoting high-efficiency material removal and cycle times. The machine is designed with optional pallet changer integration for improved automation. The Big Plus spindle system enhances ATC repeatability within 1 micron, reduces spindle axial movement at high speeds, and extends tool life by optimizing rigidity at the tool interface, making it ideal for precision and heavy cutting applications.
