Morse taper shank bar examination bar examination 
 Morse taper shank test rods standard straight bar (shaft) by JB/T9881-99 standards for manufacturing, testing a variety of machine tools with a geometric precision, using high quality carbon tool steel manufacturing, processing, after repeated heat treatment, precision grinding face cut is made. 
 Morse taper is a taper of international standards, with the precise location for the static. The 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 remove. Taper in the same range, the workpiece is free entry, while at work Shiyou not affect the results, such as drilling taper shank drills, drill bits need to be demolished if the use of grinding, re-installed after the demolition is not will affect the center of the drill. 
 Morse taper shank test rod: cone tool for checking the accuracy, precision test bar with Morse taper shanks for machine tools and precision instruments, check the spindle taper hole. 
 Morse taper, a total of seven numbers 0,1,2,3,4,5,6, there are some changes taper value, the nominal diameter size of each model 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, milling cutters) all kinds of arbor and spindle taper. 
 Morse taper cone is divided into long and short cone, long cone used for active machine tool spindle hole, a short taper for machine tool accessories and machine connection hole, a short cone with Morse, B12, B16, B18, B22, B24 six models, they are based on 1,2,3 Morse taper length shortened from, such as B10 and B12 is a No. 1 Morse taper length at both ends of the size of the general machine tool accessories according to size and torque required to choose a short drive cone, such as the commonly used 1-13 mm drill chuck are usually short with B16 cone.
