DMG Mori CMX 50 U

The DMG Mori CMX 50 U is a universal 5-axis machining center designed to bring simultaneous 5-axis contouring into mid-size shops without the footprint or price tag of a DMU or DMC platform. The machine uses a swivel rotary table (B+C axis) arrangement with a 500 mm diameter table, accommodating workpieces up to 630 mm in diameter and 430 mm tall. This trunnion-style setup keeps the part stationary relative to gravity during most operations, which simplifies fixturing and improves chip clearance compared to tool-side tilt approaches.

The spindle delivers 13 kW (17.4 hp) at 12,000 RPM standard, with optional 15,000 or 18,000 RPM high-speed versions for aluminum and non-ferrous work. Spindle torque reaches 120 Nm through an HSK-A63 interface, suitable for medium-duty steel and titanium roughing at reasonable feed rates. The standard 30-tool magazine is expandable to 60 tools for longer unattended runs. X/Y/Z travels of 600 × 500 × 450 mm cover the workpiece envelope typical of aerospace brackets, medical implants, mold inserts, and complex mechanical components in this size range.

The swiveling B-axis spans ±110° with the C-axis providing full 360° continuous rotation, both driven by Direct Drive motors for positioning accuracy and elimination of backlash. Rapid traverse rates of 30 m/min in linear axes and up to 50 RPM on the rotary axes keep repositioning time low between operations. The 45-degree slant-bed design with roller linear guideways balances rigidity and speed characteristic of the CMX platform.

The CMX 50 U runs CELOS on a 21.5-inch ERGOline touchscreen with Siemens 840D sl underneath. At $350,000–$480,000 configured, it competes with the Mazak Variaxis i-500, Okuma MU-400V, and Hurco VMX30Ui. For shops moving from 3-axis to 5-axis and needing simultaneous contouring on parts under 500 mm, the CMX 50 U offers a solid German-engineered entry point into the DMG Mori 5-axis ecosystem.
