The Engine of Quick-Change Efficiency

The Nextas Zero-Point Clamping System is the high-performance engine behind modern workholding. These precision-engineered modules provide the powerful clamping force and flawless repeatability needed to slash setup times from hours to seconds, forming the core of any effective quick-change or automated manufacturing strategy.

Module Core Features

Micron-Level Repeatability: Guarantees a repeat positioning accuracy of ≤ 0.003mm, ensuring consistent quality for every part.
Fail-Safe Mechanical Locking: Clamps with powerful spring force and unlocks with pneumatics. This "normally closed" design ensures workpieces stay locked even if air pressure is lost.
Immense Clamping & Pull-In Force: Provides exceptional rigidity to withstand the most demanding cutting operations without vibration or movement.
Automation-Ready: Designed for seamless integration with robotics, featuring ports for pneumatic control, air-blast cleaning, and clamp/unclamp status detection.

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.
