Highlights

Flexible thin turret

A versatile thin turret configuration offers tremendous capacity and flexibility. ST models feature 29-station capacity with three 3.5” auto-index stations. VT machines offer 40 tooling stations with four 3.5” auto-index stations

Hardened steel bushings

Each turret station features a hardened steel bushing to ensure tight punch alignment for the life of the machine. All stations are also keyed to allow shaped tooling to be used.

Stress-relieved bridge frame

A stress-relieved bridge frame offers minimum deflection during full tonnage punching, ensuring proper punch and die alignment.

Programmable and relocatable work clamps

Automating work clamp movement between jobs and during a punching cycle helps reduce setup time and increase productivity. Three programmable and relocatable work clamps can be automatically relocated during a punching cycle for full sheet utilization.

Smart Stroke

Smart Stroke automatically determines the optimal tool hover height to deliver the highest punching rates possible.

Smart Clamp

Automatically determines work clamp locations based on tool size, providing the smallest possible no punch zones to maximize sheet usage.

Programmable parts removal chute (VT-1530)

Strippit VT-1530 punch presses feature a programmable parts chute to easily remove punched parts. The large 19.7” x 17.7” parts chute allows finished parts to be directed through a drop door, evacuating the part on the side of the machine frame.
