DOOSAN VM 750 VERTICAL MACHINING CENTER

Technical Description

The Doosan VM 750 is a precision vertical machining center engineered for high-speed, high-precision mold and die processing. This 3-axis CNC machine features a robust table measuring 63 x 31.5 inches with a maximum loading capacity of 6,613 lbs, accommodating substantial workpieces for demanding applications. The machine delivers rapid traverse rates of 20 m/min (787.4 ipm) across all axes, enabling efficient material removal and reduced cycle times. Equipped with a 6,000 RPM spindle utilizing a dual contact BT-50 taper, the VM 750 provides excellent rigidity and stability for interrupted cutting operations. The automatic tool changer (ATC) holds 30 tools with a rapid 3-second tool change time, optimizing production efficiency. Machine construction emphasizes heavy-duty rigidity through box-type bed, column, and saddle design with wide guide structures that minimize vibration and ensure stable cutting performance. The FANUC 31i-A CNC control delivers advanced contour control and optimal feed management for complex geometries. Precision machining capabilities include roundness accuracy of 8.2 micrometers and surface roughness of Ra 0.22 micrometers under optimal conditions. The machine's comprehensive feature set includes rigid tapping capability, spindle orientation, through-spindle coolant delivery, and optional fourth-axis compatibility, making it highly versatile for precision manufacturing environments requiring consistent accuracy and reliability.
