Measuring and monitoring system for grinding machines

Versatile building block system for measuring and monitoring grinding machines – VM25 for the SINUMERIK 840D/840D sl controls

The VM25 system contains the hardware and software components required to ensure productivity, economy and quality of the grinding process – using either manual or automatic operations.

Software package – VM25-HMI

The user interface VM25-HMI can be easily integrated by the user into his application program, or activated as independent task that can be used immediately.

Thanks to a complete programming interface, based on an Active X library, the program can interact with the devices and the operator for managing the following functions:

• Balancing the grinding wheel at 1 or 2 planes, made possible by high precision balancing heads without torque effect (patented), to achieve the maximum surface quality of the ground workpiece
• Using acoustic, hydrophone and power sensors:
  • Determining the grinding wheel contact to optimize the machining and finishing cycles
  • Recording of the normal cutting characteristic patterns to monitor and signal process irregularities
• Comparative in-process measurement of the workpiece, with immediate correction feedback signal to the CNC/PLC for the diameter, the lengths and the current positions, as well as for roundness deviations (patented), to avoid missing parts and to secure consistent production quality
• FFT analysis to monitor machine vibration levels and diagnose faulty components
• Data collection referred to measurements, internal and externalevents – with subsequent transfer of this data to other suitable media for process analysis
• Network connection to a remote PC, in the master or slave mode, via teleservice
