Electronic optical finder for rapid, accurate edge finding and position setup on milling machines and jig drills. Key benefits Saves setup time: quickly locates workpiece edges and reference positions so you can start machining faster. Improves accuracy: 0.005 mm accuracy helps ensure precise reference points for repeatable setups. Reduces risk of damage: spring-loaded probe absorbs accidental overrun and protects the sensing tip. Simple operation: hardened, ground probe does not need to be rotated during measurement, simplifying use and minimizing setup errors. Broad compatibility: fits a range of traditional milling machines and integrated processing machines. Primary features Function: electronic optical edge finder for locating edges and positions. Compatibility: suitable for traditional milling machines and integrated processing machines, and for use with jig drills. Probe: hardened and ground; designed to measure without rotation. Safety: spring-loaded mechanism prevents accidental damage from overrun. Size: shank diameter 20 mm; probe diameter 10 mm. Performance: measurement accuracy 0.005 mm. Typical applications Milling machine setups: quickly find X/Y zero and edge positions when securing workpieces on a vertical or horizontal milling machine. Jig drill and drilling fixtures: locate hole centers and reference edges before drilling operations to reduce repositioning time. Integrated processing or multi-operation workflows: establish precise reference points across multiple machining steps to maintain alignment and repeatability. Specifications Shank diameter: 20 mm Probe diameter: 10 mm Accuracy: 0.005 mm Probe condition: hardened and ground Measurement: does not require rotation Protection: spring-loaded probe to prevent damage from overrun Usage tips Mount the finder securely in the machine spindle or appropriate holder with the 20 mm shank. Bring the probe into gentle contact with the workpiece edge; the optical/electronic indication will mark the contact point. Avoid excessive axial force; the spring-loaded probe is designed to absorb occasional overrun but is not a substitute for careful handling. This electronic optical finder provides straightforward edge finding and positional alignment with high accuracy, compatibility with common machining equipment, and built-in protection to reduce setup risk.
