OVERVIEW

DOCUMENTS

AVAILABLE ON THESE MACHINES

This Haas-designed 120+1 side-mount tool changer holds 120 tools, plus one in the spindle, providing plenty of locations for back-up tooling, or setting up tools for multiple jobs. It is the perfect choice for high-volume production, or for unattended, lights-out operation with a pallet pool, cobot, or robot.

The tool changer features a high-speed double-arm gripper that swaps tools quickly to minimize non-cutting time, and a bi-directional servo-drive system allows direct positioning to any tool in the carousel. Faster positioning reduces cycle times during short machining operations, or when the carousel is not pre-staged for the next tool. A remote load station with automatic lockout function allows tool inspection, loading, and unloading while the machine is cutting, simplifying tool maintenance, and eliminating the need to load tools through the spindle.

With adjacent pockets empty, the tool changer will accept oversize tooling, and there’s a built-in automatic recovery process, should a tool change be interrupted for any reason.

Currently available for these models: UMC-500SS, UMC-750SS, VF-3SS, and VF-4SS.
