Touch detection amplifier for grinding machine & machine tool 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
