1、Wide Application: Used for tool measurement, wear and tear detection, tool breakage detection, etc. on CNC machine tools, engraving and milling machines. When exceeding the travel limit, an alarm signal will occur to prevent damage accidents.2、Smart Alarming: When the overtravel alarm signal exceeds the stroke, an alarm signal will be issued. Can directly input to NC and programs, with stable performance.3、Reliable Working: This is a normally open 6 wire high accuracy tool setting instrument with a stroke of 8mm and 0.001 mm positioning accuracy, contact life up to 3 million times, contact force 1N.4、Great Durability: Dustproof and waterproof structure, preventing coolant and iron filings from flying. Still has good durability.5、Stable in Operation: The tool setting instrument does not require a built in amplifier, and there will be no deviation caused by temperature and power voltage fluctuations in the position where the tool setting instrument is located.6、High Accuracy: The protruding angle of the tool directly contacts the tip of the tool related to the machining size, measuring its position, size, and output signal. The accuracy is high.
