Practical Design Features
-
- Super-Hard Roller Needle Probes: The device utilizes a highly concentric, hardened steel needle setup. This design minimizes shaking or axis deviation during high-speed rolling, protecting delicate display panels from scratching or impact cracking.
- Resilient Needles: If the needle bends slightly after extensive high-torque use, the metal composite allows it to be manually straightened and calibrated back to factory concentricity.
- Dust Detection: The green LED light source highlights surface unevenness and tiny clear adhesive particles that are otherwise invisible under standard white workbench lighting.
