Morse taper shank test rods with high-quality carbon tool steel or pipe joints of manufacturing and processing, after repeated handling, work surface Precision cut from high hardness, good finish, accuracy and stability cylindrical error of ≤ 0.002mm taper of 0.001 / 100. 
 Morse taper shank test rods: for accuracy checking tool cone Morse taper shank test stick, high-precision machine tools and precision instruments, spindle taper hole check. 
 Morse taper shank test rods: the manufacture of standard straight rod (mandrel) (0 # -6 #) the press JB/T9881-99 standard for the geometric accuracy of the inspection and a variety of machine tools, high-quality carbon tool steel, processing after multiple heat treatment, precision face grinding from. 
 The Morse taper is a taper of international standards for static with precise positioning. Taper is small, the use of the principle of friction, you can pass a certain torque, but also because it is with the taper, so you can easily demolition. Within a certain range of the same taper, the workpiece can be freely removable, while at work Shiyou not affect the use of effects, such as drilling of the taper shank drill, if you are using need to remove the drill bit grinding, demolition and re-installed will affect the center of the drill. 
 Morse taper, 0,1,2,3,4,5,6 a total of seven number taper value changes for each model of the nominal diameter size were 9.045,12.065,17.78,23.825,31.267,44.399 63.348. Mainly used for a variety of tools (such as drills, routers) Arbor and the machine spindle taper. 
 Morse taper into a long cone and short cone long cone used for the active machine tool spindle bore, short cone for machine tool accessories and machine connection holes Mohs short cone six models of B12, B16, B18, B22, B24 shortened from, they are based on the Mohs long cone 1,2,3, such as B10 and B12 is the size of both ends of the long cone on the 1st, Mohs, general machine tool accessory according to the size and the drive torque required to choose a short cone. such as commonly used in drill chuck 1-13 mm, usually B16 short taper test rods should be placed in clean dry place to store for next use.
