Cylindrical inspection rod

The cylindrical inspection rod is used to check the taper of tool cones,and the cylindrical inspection rod is suitable for checking the taper of machine tools and instrument spindles and holes.

The cylindrical inspection rod is used to test the geometric accuracy of various machine tools.The cylindrical inspection rod is made of carbon tool steel and undergoes multiple heat treatments during processing.The working surface is ground,with good smoothness and stable accuracy.The hardness of the cylindrical inspection rod is measured using a Shaw hardness machine,and the metric inspection rod is a comparative verification tool.During use,attention should be paid to avoiding collisions and scratches on the working surface.After use,it should be cleaned thoroughly and coated with oil to prevent rust,Hang vertically or store in a wooden box.

The specifications of cylindrical inspection rods include:φ12 x 150;φ20 x 250;φ25 x 300;φ30×300;φ30 x 350;φ32×400;φ43×500;φ47×600;φ50 x 700;φ50 x 750;φ60×800;φ64 x 1000;φ80 x 1500.

The taper of the cylindrical inspection rod is a taper standard used for static fitting and positioning.Due to the small taper,torque can be transmitted using the principle of friction,and because it is a taper fit,it can be easily disassembled.Within the same taper range,the workpiece can be freely disassembled and assembled without affecting its effectiveness during operation.For example,if a drill with a tapered shank needs to be disassembled for grinding during use,reinstalling it after disassembly will not affect the center position of the drill.
