Core Locking Technology

Zero-Point Clamping Systems

Q: How does the 'fail-safe' mechanical locking work?

Our zero-point system uses powerful, pre-loaded springs as the primary locking mechanism. Clamping is mechanical and constant. Pneumatic pressure (6 bar) is only used to *unlock* the system. This fail-safe design ensures that if air pressure is lost, your workpiece remains 100% secured, preventing damage or interruption.

Q: What is the difference between the 'Bottom Inlet' and 'Side Inlet' solutions?

The inlet solution refers to how the pneumatic lines are connected. The 'Bottom Inlet' (most common) routes air lines directly through the machine table or sub-plate for a clean, protected setup. The 'Side Inlet' is a flexible alternative for applications where through-table routing isn't possible, allowing air lines to be connected to the side of the module.

Q: Can these modules be used for applications other than CNC machining?

Yes, absolutely. The high precision and rapid changeover capabilities are ideal for many applications. We see them used in CMM (Coordinate-Measuring Machine) inspection stations, welding fixtures, assembly lines, and EDM processes where precise, repeatable positioning is critical.

Q: What maintenance is required for the zero-point modules?

The modules are designed for high durability with hardened, corrosion-resistant steel. The integrated self-cleaning air blast (on automation-ready models) clears most debris. We recommend periodic inspection and cleaning, and application of a light, specialized grease (as specified in the manual) to the locking mechanism to ensure a long and reliable service life.

Q: How do I integrate the system for automated position monitoring?

Our automation-ready modules are equipped with integrated sensor ports. These allow for the installation of proximity sensors (e.S., M8 sensors) that provide a 'clamped' or 'unclamped' signal. This feedback can be wired directly to your machine's PLC or robot controller to confirm the system's status before starting an automated cycle.

Mechanism Details

Engineered for Unfailing Performance

Nextas Zero-Point modules are the foundation of modern manufacturing efficiency. Each module is crafted from high-grade, hardened alloy steel for maximum rigidity and service life. The ingenious internal mechanism uses pneumatic pressure (typically 6 bar) to overcome powerful springs for unlocking. When the air is removed, these springs instantly and forcefully pull in and lock the clamping stud, creating a positive, vibration-proof connection that is completely secure.
