TOUCH DETECTION AMPLIFIER FOR GRINDING MACHINES 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. It 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 Reduces cycle times Improves safety and reduces maintenance costs Integration with the machine controller in safety mode Extends lifetime of the tools (i.e. grinding wheel, dressing unit) Wide range of AE sensors (static assembly and built-in spindle) Does not require surveillance AE level displayed on led bar graph Can be installed on any type of grinding machine, both new and retrofitting Two control limits (i.e. end of the cutting in the air, anti-crash) with the signal processing both in instantaneous and
