Knife Edge Ruler
Magnesium aluminum knife-edge ruler is used for straightness and planarity measurements by the light-gap method, and it can also be used to check planarity accuracy with a measuring block. Its simple design enables convenient operation and high measurement efficiency in machining. Straightness error is controlled at approximately 1 μm, and the measurement surface roughness is 0.025 m.

Product Description
Precision Carbon Steel Knife-Edge Ruler, Elevator Cylinder Head Ruler, Magnesium-Aluminum Knife-Edge Ruler
The magnesium-aluminum knife-edge ruler is mainly used for straightness measurement and flatness measurement using the light-gap method. It can also be used together with measuring blocks to verify the accuracy of the plane. Its advantages include a simple structure, convenient operation, and high measurement efficiency. It is a commonly used measuring tool in mechanical processing. It generally provides high accuracy, with straightness error controlled within 1 µ. The measurement surface roughness is about 0.025, with an accuracy of m. Knife-edge rulers should be made of alloy tool steel, bearing steel, or magnesium-aluminum alloy materials. They should undergo stability treatment and demagnetization treatment.
The magnesium-aluminum knife-edge ruler is used to measure straightness and flatness errors and should be used together with a feeler gauge. During measurement, place the edge of the knife-edge ruler perpendicular to the measured plane, and use a feeler gauge to fill the gap under the edge to measure the flatness error. During inspection, if the light transmission between the edge ruler and the workpiece plane is weak and uniform, the flatness of the workpiece is qualified. If the light intensity is uneven, it indicates that the workpiece surface is uneven. The flatness error can be determined by inserting a feeler gauge at the close position between the edge ruler and the workpiece, based on the thickness of the feeler gauge.
Advantages of the magnesium-aluminum knife-edge ruler: lightweight, convenient to use, not easily deformed, not rusty, and easy to store.
