DONAU DONAUALPHA VERTICAL MACHINING CENTER

Technical Description

The Fadal VMC 4020B II is a precision vertical machining center engineered for high-volume production and toolroom applications. This machine features a 47.2" × 23.6" work table with an optional support index table, providing substantial workspace for diverse workpiece configurations. The vertical spindle operates at a maximum speed of 3,050 RPM with a MT#4 taper, delivering 2.10 HP at 30-minute rating—ideal for heavy-duty cutting operations requiring sustained torque and material removal rates. The machine is equipped with a standard three-pallet changer system, enabling efficient multi-part production sequences without manual intervention. It utilizes a manual tool carrier configuration with a single tool position, optimizing setup efficiency for dedicated production runs. The four-axis design incorporates substantial X, Y, and Z travels of 32.5", 35.4", and 5.5" respectively, accommodating large workpieces across the machining envelope. Built with rigid box-way construction featuring ground and hardened surfaces with non-metallic liners, this vertical machining center minimizes vibration and ensures consistent dimensional accuracy. The design delivers maximum repeatability through friction-free way surfaces, critical for maintaining tight tolerances across production batches. This configuration makes the VMC 4020B II particularly suitable for precision component manufacturing, mold work, and production jobs requiring dependable performance and extended tool life in industrial environments.
