Introduction
The BENDCHECK system by ZUMBACH offers a non-contact solution for in-line straightness measurement of tubes and bars, enhancing quality assurance without manual intervention. This system is crucial for manufacturers who need to adhere to strict straightness specifications.

System Functionality
BENDCHECK is installed in-line to measure the straightness of each product without disrupting production. It provides real-time monitoring and can measure head and tail bending with additional stations. The system supports 1-, 2-, or 3-axis laser measuring stations and integrates directly into the production process.

Advantages

• Real-time synchronous scanning for bending monitoring.
• Optional head and tail bending measurements.
• Direct integration into production processes.
• Quality assurance post-straightening, crucial for the steel industry.
• Statistical data collection for traceability.
• Eliminates the need for manual checks.

Measurement Process
The system measures bend/deflections at three defined locations along the product's axis, calculating deviations from a virtual straight line. Operators can choose the formula for bend calculation based on product requirements. Measurements are continuously calculated and displayed graphically.

Technical Specifications
The BENDCHECK system is available in various models (100, 160, 230, 310) with different product size ranges and measurement errors. Adequate product guiding is required for accurate measurements.

System Components and Communication
BENDCHECK systems can be configured with different measuring stations and communication ports, including Ethernet. The BENDCORE processor offers Ethernet communication, allowing direct integration with PLC or PC systems. It also features a built-in Web Server and optional OPC UA interface.

Data Management
The USYS Data Log software facilitates data collection and storage in text or Excel files. The USYS system supports various communication protocols, including OPC UA, for industrial automation and data management.

User Interface
The USYS BARMASTER provides a user-friendly interface for parameter selection and displays measurements numerically and graphically. It includes SPC charts and extensive statistical displays.

Conclusion
The BENDCHECK system offers a comprehensive solution for in-line straightness measurement, enhancing quality control and efficiency in manufacturing processes.
