Proven Precision Consistently Refined.
With its latest optimization, the proven C-Frame roll measurement system now features a more modern, lighter, and even more service-friendly design ─ without compromising on precision or process reliability.
The key advantage of the C-Frame measuring system lies in its intelligent combination of the highest measurement precision and exceptional process speed. This reduces lead times, increases productivity, and ensures consistently high process quality ─ for greater efficiency in every application.Through continuous 2-point contact with the roll, the C-Frame measurement system enables absolute measurements for the highly accurate detection of concentricity, shape, and roll diameter.
In addition, the C-probe ─ which extends the 2-point measurement to a 3-point measurement system ─ precisely measures and aligns the roll with the horizontal axis. The geometric data determined enables the precise detection of shape deviations and lays the foundation for the highest level of measurement reliability.
Slim Design. Lightweight Construction. High Performance. Easy Maintenance.
Design Meets Performance
With its latest refinement, the proven C-Frame measuring system combines a more modern, lightweight and service- friendly design with the same uncompromising precision and process reliability.
The high-precision C-Frame measuring systems bring exceptional accuracy directly into the grinding process. Shape deviations, diameter variations and surface irregularities are detected in real time – enabling precise process control, consistently high product quality, reduced material removal and shorter grinding times.
Intelligent In-Process Measurement for Maximum Efficiency
Perfectly coordinated components enable the high-precision C-Frame measuring system to deliver exceptional accuracy and repeatability directly within the grinding process. Deviations are detected in real time and automatically compensated for by the machine control system.
Seamless integration with the Herkules roll grinding machine control system enables autonomous, digitalized grinding processes with comprehensive monitoring and documentation. This results in extended service life, increased throughput and maximum resource efficiency.
