LFY-247A Sharp Edge Tester

Main purpose

Used for testing sharp edges of textile accessory items (such as metal and plastic accessories) and children's toys; it can meet the standard testing requirements for textile accessories and toys. 
Technical indicators
Motor control drive, with short response time, no overshoot, and precise and uniform speed. 
2. By using high-precision force sensors, it is possible to ensure that the force value during the test remains within the range of 60 - 0.5N. The sensors also have an over-range protection function. 
3. The mainboard is equipped with a self-developed single-chip microcomputer, a color display screen, and a menu-style selection interface, making the operation very convenient. 
4. Rotating the core shaft: Made of stainless steel, with a surface roughness of ≤ 0.40 μm. The diameter of the core shaft is (9.35 ± 0.12) mm. The rotation angle of the core shaft is 360°, and the tangential rotational speed is (23 ± 4) mm/s. 
5. The force application device exerts a force perpendicular to the axis of the core shaft, with a value ranging from 60 to 0.5 N; c. The test strip meets the standard technical requirements.
