High-Pressure 250 Bar Self-Centering Vise

Hydraulic Self-Centering Vise

Vektek provides a specialized high-pressure hydraulic vise that delivers extreme clamping pressure. Our 250-bar VCV Hydraulic vise is suitable for manufacturers who require secure workpiece positioning during aggressive material removal. We offer two high-clamping-force vises, VCV 100 and VCV 160, and other self-centering options for machining applications that don’t require high pressure.

Catalog Section | Install / Maintain

Max operating pressure 3625 psi / 250 bar.
High jaw repeatability: VCV 100: 0.01MM and VCV 160: 0.02MM
Wedge and piston design.
Stroke range from 12 to 16MM.
Operating temperature range from 5 to 60°C.
Hardened steel construction.
Inductive sensors can be mounted for open, closed and part clamp detection. Requires the use of the S mounting kit.
The PC option adds the ability for pneumatic part presence sensing and blow off when manifold mounted by adding a pneumatic port at the top of the jaw.
The MB option adds the ability for pneumatic jaw position sensing for clamp and unclamp. Each state uses a separate port, so they can be used individually to detect a single state, or together to also verify part clamping.

* The gripping force is the arithmetic sum of the individual forces at “F” distance at max pressure.

** Closing and opening times are purely the times that the base jaws are in motion. Valve switching, hose filling,

PLC/CNC reactions, and other potential delays are not included and must be taken into consideration when

determining cycle times.

The PC option adds the ability for pneumatic part presense sensing and blow off when manifold mounted by supplying compressed air to the jaws. This air can be routed through jaws and used to blow off the jaw faces before machining, or the port can be positioned to be covered by the part to increase air pressure and verify part presence.
The MB option adds the ability for pneumatic jaw position sensing for fully clamped and unclamped. Each state uses a separate port, so they can be used individually to detect a single state, or together to also verify part clamping. Use max of 2 bar air pressure. Can be used with 50-8240-00 air sensing control kit.

A 250-Bar Vise Engineered for Extreme Clamping Force

Standard workholding devices can distort under heavy cutting loads. Our high-force vise features hardened steel construction and an optimized wedge and piston design. This combination maintains rigidity and high jaw repeatability — up to 0.01MM — across multiple production cycles.

The VCV 100 delivers up to 16,000 N of clamping force, which supports dense aerospace alloys and medium-sized forgings. Our VCV 160 model delivers up to 44,000 N of clamping force at a maximum operating pressure of 250 bar, making it suitable for holding massive steel castings and heavy equipment components.

Industries That Use Heavy-Duty Hydraulic Vises

We engineered the VCV high-pressure machine vise specifically for industries that push their machine tools to peak performance levels:

Aerospace manufacturing: Secure large structural components and mill exotic alloys like Inconel or titanium and minimize chatter.
Heavy equipment production: Clamp massive steel castings, heavy forgings and thick plate stock securely to maintain tight tolerances during deep boring and facing operations.
Ultra-aggressive milling: Stabilize parts during heavy roughing operations that feature exceptionally high material removal rates.

Frequently Asked Questions

These answers help you understand how our industrial hydraulic vise integrates into your high-performance machining cell.

Do I need the VCV, or is the VFB Hydraulic sufficient?

For typical heavy-duty applications like standard steel milling and aluminum roughing, the VFB Hydraulic provides sufficient force. The VCV excels in applications featuring massive workpieces, exotic materials or extreme cutting parameters, such as high-speed titanium machining or deep-cut boring in hardened tool steel.

What hydraulic system is required for 250-bar operation?

A 250-bar operation requires a dedicated high-pressure hydraulic power unit. We recommend pairing the VCV with our Advanced Automation Workholding Pump to reliably generate and control the required 250-bar pressure.

Is the VCV more force than my application needs?

If you mill aluminum or mild steel, or use standard material removal rates, we recommend the VFB Pneumatic or VFB Hydraulic. The VCV serves specialized extreme-force applications, while the VFB Pneumatic uses standard shop air and delivers the fastest actuation speeds for rapid cycle times and lighter part production.

Can Vektek provide the complete high-pressure system?

Yes. We supply the VCV vise and a complete lineup of hydraulic workholding systems, including a high-pressure hydraulic power unit. With a complete power and control ecosystem, we can help you integrate the VCV more safely and effectively.
