DIN 875 steel plate ruler 75mm 125mm 175mm 200mm 225mm 300mm

Details: ● Use the optical gap method to check edges. Blades are beveled on both sides with insulated handles. ● Comes with protective case. ● Application: Detect the flatness of plates leveling rulers machine tool working platforms guide rails and precision workpieces. 1) Hold the steel ruler edge perpendicular to the workpiece surface and check in the longitudinal transverse and diagonal directions 2) During inspection if the edge and plane of the workpiece are weak and uniform the flatness of the workpiece is acceptable; if the intensity of the incident light is different the plane of the workpiece is uneven. It can be inserted with a feeler gauge on the cutting edge and the workpiece. The flatness error can be determined according to the thickness of the hand. feature: Material: Tool Steel Length: 75/100/125/150/200mm/300mm Accuracy: DIN 874/00 Package includes: 1* steel ruler
