High Precision ‒ For More Accurate Torque Output

Dual dynamic sensors with algorithmic compensation control deliver ultra-high precision with �σ accuracy of ±�.�%, enhancing the reliability of critical connections.

Front-end Positioning for More Accurate Measurement

Dynamic torque sensors capture real-time torque changes at the front end of the spindle, minimizing transmission errors and ensuring higher measurement consistency.

Dual Sensors, Double Assurance

Two dynamic torque sensors provide mutual data backup and cross-veriﬁcation, further enhancing long-term operational reliability at critical stations.

Synchronous Tightening ‒ For More Consistent Multi-Axis Coordination

Supports synchronous control of up to �� axes, ensuring coordinated execution across all tightening steps, guaranteeing consistency and stability in connection qualityat critical workstations.

Synchronous Online Rework ‒ Quality Closed-Loop Without Line Stoppage

When a single axis encounters an issue, the systemautomatically performs rework operations without requiring a full-group redo, reducing line stoppages and repeated work, and maintaining stable production cycle times.

Uniﬁed Data Management ‒ Simpler Full-Line Traceability

Tightening data is consolidated to the main control platform, enabling centralized full-line data management and uniﬁed traceability, providing eﬃcient oversight of tightening status across all stations.

Advanced Strategies ‒ For More Reliable Critical Connections

Multiple advanced tightening strategies cover process control needs at various stages throughout the tightening process, eﬀectively improving tightening quality at critical joint points.

Yield Point Control ‒ Maximizing the Performance of Every Bolt

Real-time identiﬁcation of the yield point ensures the bolt enters its optimal stress state, enhancing long-term reliability and consistency of preload force in critical joints.

Zero-Speed Hold / Delay Control ‒ Reducing Torque Decay

Eﬀectively mitigates torque decay, further enhancing the stability and consistency of ﬁnal preload force in critical connections.
