The VF-2SS is a high-performance vertical machining center that comes standard with an innovative 12,000-rpm inline direct-drive spindle, an ultra-fast tool changer and 1,400-ipm rapids.
The machine is equipped with a 12,000-rpm, 40-taper spindle that features a unique inline, direct-drive system that couples the motor directly to the spindle rather than using belts. This results in less vibration, less heat and less noise than other drive systems, providing better surface finishes, extreme thermal stability and very quiet operation. Powered by a 30-hp vector drive system, the spindle yields plenty of low-end torque, as well as the speed necessary for high-speed machining operations.
The VF-2SS also features a high-speed side-mount tool changer with 24+1 tools. Lighter materials and a high-performance servo motor make this tool changer the fastest that Haas has ever built, with tool changes taking less than 1.6 seconds tool to tool. To further reduce cycle times and keep non-machining time to a minimum, the VF-2SS uses high-pitch ballscrews and high-torque servo motors on all axes to provide rapids of 1,400 ipm.
While the VF-2SS offers substantial performance in base configuration, it is possible to boost capabilities even further with a high-performance package of options. This package includes an auger-style chip conveyor, programmable coolant nozzle, 16 MB program memory, Visual Quick Code programming, floppy disk drive, spindle orientation, 4th-axis drive, coordinate rotation & scaling, user-definable macros, remote jog handle and high-speed machining software.
