FISCHER has the Solution!
SmartSolutions for FISCHER spindles provide customers with comprehensive solutions within the sectors of frequency converters (SmartDrive: more torque, increased performance, reduced losses), spindle monitoring (SmartVision: load profile, spindle condition, service intervals), as well as process data logging (SmartEye: miniaturized design, data logging integrated within the spindle, data logging with battery back-up).
Ever-greater demands for available performance and torque made it inevitable that FISCHER would respond by embracing frequency converter technology. The result of this effort is the SmartDrive frequency converter system. With a modulation frequency of up to 40 kHz, available currents of up to 300 Aeff, and an integrated industrial PC, SmartDrive represents a milestone in the development of frequency conversion technology. The plug-in SmartDrive system allows you to access all relevant operational and status data relating to the spindle via a Bus interface.
Thanks to its monitoring capabilities and its ability to provide performance data at high rotational speeds, SmartDrive is the leading frequency converter for HSC and HPC applications. Performance losses as a result of the de-rating effect can be almost eliminated.
Furthermore, thanks to SmartDrive’s integrated industrial PC, it is also possible to integrate FISCHER’s SmartVision monitoring system.
SmartVision is a tool for analyzing process data. Through the application of SmartVision, it is possible to selectively optimize a work process.
The monitoring of main spindles has been an enduring topic for many years. Work groups and researchers from universities and industry have concentrated on finding suitable measurement categories, measurement and evaluation techniques, as well as strategies for minimizing premature failures and machine downtime.
The solutions they found range from single-sensor systems based on temperature or vibration measurement and simple logging of the recorded data, to systems with multiple sensors (e.g. temperature, vibration, distance, or force meters). With this, analysis requires multi-dimensional classifications with adaptive filters. The majority of these systems have not been tested industrially.
FISCHER AG has also been intensively engaged in the matter of spindle monitoring. The development and launch of SmartVision made significant waves within this application arena; furthermore, it led to SmartVision’s status as one of the few industrially tested and successfully implemented, operational monitoring systems for spindles.
SmartEye is a system for logging process data in a compact format. It acts as an aid for visualizing process data, helping to make it accessible for users.
Vibration measurements are generally used for:
• Monitoring the condition of spindles and mountings
• Identifying imbalance situations
• Process monitoring
To externally reduce interference factors that can affect signal quality, we recommend adapting the spindle vibration sensor according to the intended surface, or integrating it into the spindle. For this, Fischer AG uses tried and tested systems. Besides the sensor itself, the processing of signal data and the manner of evaluation also play significant roles in appraising vibrations. We would be delighted to assist you in finding the solution that is right for your particular application.
