High-Precision Pneumatic Vise
Engineered for Automated Production
The Nextas high-precision pneumatic vise is a powerful clamping device developed for automated machining and mass production. Its built-in pneumatic-hydraulic booster system generates a strong and stable clamping force using standard factory air pressure. It is ideal for automated loading and unloading with robotic arms, making it an indispensable tool for building automated production lines and increasing efficiency.
Core Advantages
- Powerful Boosted Clamping Force: The built-in booster cylinder can generate a clamping force of up to 4000 kgf, easily handling various heavy-duty cutting tasks.
- Fast and Stable Actuation: Pneumatic drive achieves rapid opening and closing, with a clamping time of just a few seconds, significantly reducing the machining cycle time.
- High Integrability: Can be linked with the machine tool's M-code via a solenoid valve for easy integration into automated systems, enabling unmanned operation.
- Robust and Durable Construction: The vise body is made of high-tensile ductile iron (FCD60), and the sliding surfaces are high-frequency heat-treated to ensure long-term accuracy and durability.

Pneumatic-Hydraulic Booster Technology
The core of the Nextas pneumatic vise is its innovative "pneumatic-to-hydraulic conversion" booster technology. When compressed air enters the vise, it pushes a large-area piston, which in turn pressurizes a small-area hydraulic chamber. According to Pascal's principle, this design can amplify the force of the air pressure by several tens of times, thereby generating a powerful hydraulic clamping force. This design combines the rapid response of pneumatics with the powerful locking force of hydraulics, and it operates with only a standard air source, eliminating the need for an additional hydraulic power unit and greatly simplifying system configuration.
Designed for Harsh Environments
We understand the challenges of the machining environment. Therefore, the Nextas pneumatic vise features a fully sealed design that effectively prevents contaminants such as chips and coolant from entering the internal mechanism, ensuring long-term stable operation even in harsh conditions. The vise body is integrally cast from FCD60 high-tensile ductile iron, which effectively absorbs cutting vibrations, ensuring machining stability and a superior surface finish on the workpiece.
Flexible Installation and Application
The base of the vise is precision-ground and comes with standard keyways and mounting holes for quick and accurate installation on the T-slot tables of various machining centers. Additionally, it can be easily combined with our zero-point clamping system to achieve even faster fixture changeovers, further enhancing production efficiency and flexibility.
Automated Machining Cells
The rapid actuation and electronic control integration of the pneumatic vise make it a perfect partner for robotic arm automated loading/unloading systems, enabling long periods of stable, unmanned production.
Mass Production of Parts
On production lines in industries like automotive, electronics, and hardware, the pneumatic vise provides consistent and reliable clamping force, ensuring the quality of every product and significantly shortening the cycle time per part.
Horizontal Machining Centers
Ideal for use on the pallet changers of horizontal machining centers. Multiple pneumatic vises can be installed on one pallet, allowing for the machining of several workpieces in a single setup, maximizing equipment productivity.
Heavy-Duty Cutting Applications
With its powerful boosted clamping force and rigid construction, the pneumatic vise can securely hold workpieces under high-feed, deep-cut conditions, making it a reliable choice for heavy-duty tasks like mold roughing.
