Willemin-Macodel W-401 VERTICAL MACHINING CENTER

Technical Description

This CNC vertical machining center features a compact work table measuring 15.7" x 9.84" capable of handling up to 100 lbs of workpiece weight, supporting precision machining of small to medium components. It is equipped with 16 vertically oriented spindles, each featuring an ISO 25 taper, optimized for rigidity and repeatability in tool holding. The main spindle operates at a top speed of 12,000 RPM, with an option to increase to 18,000 RPM, driven by a 4.00 HP motor rated for 30-minute operation. Tooling is managed via an automatic tool changer (ATC) with a standard capacity of 24 tools, extendable to 48, enabling rapid changes with an impressive 1-second tool change time and 5-second chip-to-chip time, minimizing idle production time. The machine operates with 3 axes (X, Y, Z), with the possibility of adding a 4th axis as an option. Each axis offers precise travels of 9.84" (X), 7.87" (Y), and 11.81" (Z) with a maximum feed rate and rapid traverse speed of 786 inches per minute, ensuring fast and accurate positioning. The ISO 25 spindle taper provides a secure and accurate tool interface designed for high-speed machining, with minimized runout and enhanced stiffness. Overall, this system is suited for high-throughput, small- to mid-sized part production requiring fast tool changes, high spindle speeds, and precise 3-axis control for diverse vertical milling applications.
