Technical Description
This CNC vertical machining center features a 47.2" x 19.7" table capable of supporting up to 1,100 lbs of workpiece weight. It operates on a 3-axis configuration (X, Y, Z) with travels of 40.2", 20.1", and 22.0" respectively, supporting a maximum and rapid feed rate of 1,417 inches per minute on all axes. The spindle is vertical, equipped with a CAT 40 BIG-PLUS taper, offering enhanced rigidity and precision through simultaneous dual contact of the spindle taper and face, which minimizes deflection and improves surface finish, tool life, and tool change repeatability. The spindle has a standard top speed of 10,000 RPM, with an optional upgrade to 12,000 RPM, powered by a 15 HP motor with a 20 HP option for higher power applications. The machine includes an Automatic Tool Changer (ATC) with a 20-tool capacity, upgradeable to 30 tools, enabling a fast tool change time of 1.5 seconds to maximize productivity. There is no pallet changer or U-axis available, and support for a rotary table is optional. The overall design emphasizes machining accuracy, rigidity, and speed, suitable for machining complex parts requiring high precision and surface quality, benefiting especially from the BIG-PLUS spindle system's improved toolholder contact, which reduces axial tool movement at high speeds and increases machining stability. This combination of table size, high feed rates, powerful spindle, and advanced tooling offers a robust solution for demanding milling operations in various industrial applications.
