The Benefits of a Hydraulic Machine Vise

Automated, self-centering vises help conserve operator energy and support consistent part quality. The VFB Hydraulic uses engineered fluid power to deliver highly repeatable clamping pressure. The wedge and piston design maintains high jaw repeatability for strict tolerance control, while our hardened steel construction maintains structural integrity under high-pressure vise conditions. Versatile porting provides side or bottom connections, which allow for manifold mounting and integration into crowded machine envelopes.

Projects a Hydraulic Jaw Vise Supports

Heavy-duty environments require robust workholding solutions. We engineered the VFB Hydraulic specifically to stabilize parts in applications that require maximum rigidity:

Heavy material removal: Secure titanium, Inconel and large steel billets that exceed the capacity of a standard hydraulic vise.
Lights-out automation: Integrate with robotic tending systems for automated load and unload cycles.
Material yield optimization: Upgrade from manual vises to establish more consistent operator torque, help maintain tolerances and save material.
Multipart fixturing: Provide simultaneous, uniform clamping across multiple vises plumbed into a single hydraulic circuit to maximize spindle uptime.

Frequently Asked Questions

Explore questions about clamping capacities, actuation speeds and system compatibility to help specify the right vise for your production cell.

VFB Hydraulic vs. VFB Pneumatic: Which do I need?

Choose VFB Hydraulic for maximum holding power and aggressive machining. For faster actuation and moderate force, use VFB Pneumatic.

Do I need a hydraulic power unit, or can I use my machine’s hydraulics?

You can plumb into existing machine hydraulics if the pressure requirements match. For optimized control, we recommend pairing this vise with our Advanced Automation Workholding Pump.

Can VFB Hydraulic replace my Kurt manual vise?

Yes. An upgrade to a hydraulic clamping vise introduces automated actuation, conserves operator energy and delivers highly repeatable clamping pressure across production runs.

What jaw options are available?

We offer serrated base jaws and steel top jaw blanks, which let you custom-machine profiles for specific workpieces.

Can robots load VFB Hydraulic vises?

Yes. The hydraulic actuation integrates into automated cells and robot-tended CNC environments.

Is VFB Hydraulic overkill for my application?

Pneumatic or manual options work well for machining aluminum or lightweight plastics. Hydraulic force is suitable for applications with a high risk of part movement. Shops comparing a hydraulic bench vise with CNC hydraulic workholding options should choose based on material, cut aggressiveness and required repeatability.
