Features: _x005f_x000D_ Photoelectric edge finder features: It can be measured without turning _x005f_x000D_ Suitable for the traditional milling machine and comprehensive processing machine. _x005f_x000D_ The X and Y axes of the workpiece can be measured and set. _x005f_x000D_ When the probe comes into contact with the workpiece, a red light and a sound will appear. _x005f_x000D_ Not easy to wear,higher precision,stable performance,durable. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Specification: _x005f_x000D_ Name: edge finder _x005f_x000D_ Process: uncoated _x005f_x000D_ Large end: 20mm / 0.8in _x005f_x000D_ Small end:10mm / 0.4in _x005f_x000D_ Total length:160mm / 6.3in _x005f_x000D_ Battery: 3* LR1(not included)_x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Usage: make the spindle stop and control the probe to approach the working face slowly. When the probe comes into contact with the working face, the LED indicator lights up and gives a prompt sound. At this time, the distance between the spindle center and the working plane is 5MM. _x005f_x000D_ _x005f_x000D_ Package list: _x005f_x000D_ 1 x Edge Finder(battery not included) _x005f_x000D_ 1 x box_x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ To ensure the measurement accuracy, do not directly touch the probe with your hands _x005f_x000D_ If not used for a long time, please remove the battery to extend the battery life. _x005f_x000D_ If the battery power is insufficient, please replace the same type of battery immediately. _x005f_x000D_ This edge finder is an electronic product. It should avoid short circuit or corrosion caused by cutting fluid entering inside.
