Photoelectric edge finder with audible feedback for fast, rotation-free edge locating - Beep guided measurement without rotation: The photoelectric edge finder provides an audible beep to indicate edge detection, eliminating the need to rotate the workpiece during alignment. It yields reliable results when working with conductive materials. - Durable 20CRMNTI steel construction: Built from selected 20CRMNTI steel for enhanced durability and long-lasting performance in workshop use. - Improved loud audible signal: This version delivers a louder sound to clearly indicate edge location, making edge finding quicker and more reliable in busy or noisy environments. - Easy and convenient operation: No rotation is required for measuring—simply touch the surface to locate the edge. The simple, comfortable operation helps save time and reduces effort during setup. Applications and use scenarios - Milling machine setup: Quickly locate workpiece edges to set zero on milling machines, enabling accurate offsets for milling operations. - Drilling and tapping templates: Align edges on metal plates or fixtures to ensure precise hole and feature placement. - Fixture and jig setup in workshops: Use the edge finder to identify reference edges for repeatable positioning in fixture creation and quality control.
