Super Fast, Super Accurate VMC

Haas Automation, Inc. continues to advance its line of VMCs with higher speeds and increased capabilities. 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.

Based on the shop-proven Haas VF-2 platform (30” x 16” x 20” travels), the VF-2SS takes per-formance and affordability to a whole new level. 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.

To boost capabilities even further, a high-performance package of options 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 and scaling, user-definable macros, remote jog han-dle and high-speed machining software.
