Magnesium Aluminum Knife Edge Ruler

Magnesium-aluminum knife-edge rulers are mainly used for straightness and flatness measurement by the light gap method,and can also be used together with gauge blocks to inspect the flatness accuracy.They feature simple structure,light weight,rust resistance,convenient operation,and easy measurement,making them common measuring tools in mechanical processing.

Magnesium-aluminum knife-edge rulers generally have high precision,with the straightness error controlled at around 1μm.The roughness of the measuring surface R reaches a precision of 0.025μm.

Magnesium-aluminum knife-edge rulers are divided into two types—magnesium-aluminum alloy and steel—according to different customer needs.The magnesium-aluminum alloy knife-edge ruler is light in weight,easy to use,not easy to deform,rust-proof,and easy to store.

Magnesium-aluminum knife-edge rulers are mainly used to detect the flatness and straightness of flat plates,straightedges,machine tool worktables,guide rails,and workpieces.

Light weight of magnesium-aluminum knife-edge rulers:Magnesium is one of the lighter metals in practical use.Its specific gravity is about 2/3 that of aluminum and 1/4 that of iron,so magnesium-aluminum knife-edge rulers are very light.Even a 5-meter-long magnesium-aluminum knife-edge ruler can be easily moved by one person.

Easy storage of magnesium-aluminum knife-edge rulers:There are not high requirements for the placement of magnesium-aluminum knife-edge rulers.They can be hung or placed flat,and long-term flat placement will not affect their straightness.Moreover,they are not easy to rust.

Magnesium-aluminum knife-edge rulers have properties such as corrosion resistance and dimensional stability,and they also feature non-magnetism.
