The Haas VF-4SS is a Super-Speed CNC vertical machining center with a reputation for straightforward operation and dependable uptime that has made it a staple in job shops and production environments across the country. This 2021 Haas VF-4SS offers X, Y and Z travels of 50 x 20 x 25 inches over a 52 x 18 inch T-slot table rated for 1,750 lb, giving it room for long fixtures, multiple vises and larger parts. The machine is built around a 12,000 RPM inline direct-drive spindle with CAT 40 (CT 40) tooling and a 30 HP vector drive, and it is rated for 1,400 ipm rapids on all three axes. Tooling is handled by a high-speed 30+1 side-mount tool changer that accepts tools up to 3 inches in diameter (5 inches with adjacent pockets empty), 11 inches long and 12 lb, with a published 1.6 second tool-to-tool and 2.2 second chip-to-chip time. This unit is equipped with 4th-axis drive and wiring, a Haas control with a color touch screen, 1 GB program memory, high-speed machining, rigid tapping, Ethernet, WiFi, HaasConnect remote monitoring, HaasDrop, Media Display M-code M130, Safe Run, early power-failure detection, window air blast, a 55-gallon flood coolant tank, chip auger, low-voltage transformer and lifting provision, wired for 220V 3-phase power.
Compared with the standard Haas VF-4, which shares the same 50 x 20 x 25 inch work envelope but runs an 8,100 RPM spindle, a 20-station carousel tool changer and 1,000 ipm rapids, the VF-4SS is the faster, higher-throughput choice: its 12,000 RPM direct-drive spindle, 30+1 side-mount changer and 1,400 ipm rapids cut cycle times on aluminum, finishing passes and high-mix work. It also improves on earlier VF-4SS units built with the Classic Haas Control, adding the current Haas control platform with a touch-screen interface, 1 GB of memory, wireless network connectivity, HaasDrop file transfer and HaasConnect monitoring. Buyers get a machine that is meaningfully more capable on the shop floor, not just newer on paper, with the speed and connectivity modern production schedules demand.
