Feature: 1. 3D Edge Finder: Improve your machine tool processing accuracy with the 3D edge finder, and the repeat accuracy of 0.001MM ensures precise measurements in X, Y, and Z directions. 2. Easy to Use: Simply place the photoelectric edge finder on the workpiece surface and adjust until the red light turns on. It is a quick and efficient way to locate edges and reference points. 3. Ceramic Probe: The 3D photoelectric edge finder uses ceramic probe, which have better accuracy retention and greater swing momentum, preventing measuring errors and probe damage. 4. Battery Powered: The edge finder is powered by a 3.6V 14250 lithium battery (not included), which is convenient for use anytime and anywhere, greatly improving machining efficiency. 5. Function and Application: This photoelectric edge finder has Z axes height measurement function, which is stable and reliable, and is widely used in CNC lathes, machine tools, and more.
