Mohs inspection rod

The Mohs inspection rod is used to check the taper of tool cones,and the inspection rod is suitable for checking the taper of machine tools and instrument spindles and holes.The inspection rod is manufactured and processed using carbon tool steel or ground seam steel pipes.After multiple treatments,the working surface should be machined,with good smoothness and stable accuracy.The cylindricity error is≤0.002mm,and the taper is 0.001/100.

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

Mohs inspection rod:(0#-6#)standard straight rod(core shaft)is manufactured according to JB/T9881-99 standard,used to test the geometric accuracy of various machine tools.It is made of carbon tool steel,processed through multiple heat treatments,and the working surface is ground.

The taper of the Mohs test rod is a standard for taper used in static fitting for 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 for drilling needs to be disassembled and ground during use,reinstalling it after disassembly will not affect the center position of the drill.

The Mohs test rod has seven taper sizes,including 0,1,2,3,4,5,and 6,with varying taper values.The nominal diameter sizes for each model are 9.045,12.065,17.78,23.825,31.267,44.399,and 63.348,respectively.Mainly used for various cutting tools(such as drill bits,milling cutters),various tool holders,and machine tool spindle hole taper.

The taper of the Mohs inspection rod can be divided into long and short cones.Long cones are mostly used for the main spindle hole of active machine tools,while short cones are used for machine tool accessories and connection holes.Short cones have six models:B12,B16,B18,B22,and B24,which are shortened based on long cones 1,2,and 3.For example,B10 and B12 are the two ends of long cone 1.Generally,machine tool accessories choose to use short cones based on their size and required transmission torque,The commonly used drill chuck with a diameter of 1-13mm usually uses a short tapered hole of B16.The inspection rod should be stored in a clean and dry place for future use.
