VM9-TD is a touch detection system for machine tools based on the use of acoustic emission sensors (AE). It is designed for simple and cost-effective applications and allows to:

– Detect the end of the “air grinding” time (GAP function)

– Preventive monitoring (Anti-CRASH function)

– Control the dressing process


- Management of 2 independent channels for AE sensors, including diagnostics
- Integration with the machine controller in safety mode
- Wide range of AE sensors (static assembly and built-in spindle)
- AE level displayed on led bar graph
- Two control limits (i.e. end of the cutting in the air, anti-crash) with the signal processing both in instantaneous and in differential mode


- Reduces cycle times
- Improves safety and reduces maintenance costs
- Extends lifetime of the tools (i.e. grinding wheel, dressing unit)
- Does not require surveillance
- Can be installed on any type of grinding machine, both new and retrofitting
