Pneumatic-Hydraulic Booster Technology

The core of the Nextas pneumatic vise is its innovative "pneumatic-to-hydraulic conversion" booster technology. Compressed air pushes a large-area piston, which pressurizes a small-area hydraulic chamber. According to Pascal's principle, this amplifies the air pressure by several tens of times, generating powerful hydraulic clamping force. This design combines the rapid response of pneumatics with the powerful locking of hydraulics, operating with only a standard air source and simplifying system configuration.

What are the advantages of your pneumatic vise compared to a traditional hydraulic vise?

Our main advantage is integration. Our pneumatic vise has a built-in 'pneumatic-to-hydraulic' booster, requiring only standard factory air pressure to generate up to 4000 kgf of powerful hydraulic clamping force. This simplifies system setup, eliminates the need for an external hydraulic unit, and allows for easy integration with automation lines and machine M-codes via a solenoid valve.

What is the repeatability of this vise?

The NPV-160 pneumatic vise achieves a repeatability of ≤0.01 mm. This is crucial for automated mass production that requires high consistency.

What is special about the FCD60 ductile iron body?

FCD60 is a high-tensile ductile iron. This material provides excellent rigidity and vibration-damping capabilities. During heavy-duty cutting, it effectively absorbs machining vibrations, ensuring stability, a superior workpiece surface finish, and extending the vise's long-term durability.
