Cylindrical Square / Morse test rods

 Cylindrical Square, according to GB6092-85 standards for manufacturing, mainly for the production of parts at right angles to each other verticality inspection and marking, inspection of parts or components related to the surface can be used as the benchmark measure of 90 degrees. Taper shank test rods :( unit: piece) conical tool used to check the accuracy, precision taper shank test rods suitable for the machine tools and precision instruments taper spindle and bore taper test rods made of high quality carbon tool steel or. seam steel pipe manufacturing and processing, after repeated treatment, should be cut from the work surface precision, high hardness, good finish, accuracy and stability of cylindrical error ≤0.002mm, taper 0.001 / 100 taper shank test rods: tools used to check the cone The accuracy, precision taper shank test rods suitable for machine tools and precision instruments, and the spindle taper hole inspection. Taper shank test rods: (0 # -6 #) standard straight bar (mandrel) by JB / T9881-99 standards for manufacturing, the machine used to test a variety of geometric precision, using high-quality carbon tool steel manufacturing, processing after several heat treatment, precision grinding Face made. Taper Taper is an international standard for interference fit to pinpoint. Since the taper is small, the use of friction principle, you can pass a certain torque, but also because it is a taper fit, it can be easily disassembled. Within a certain range of the same taper, the workpiece can be free entry, while working time and will not affect the results, such as drilling taper shank drill, drill bits need to be removed if the use of grinding, after the demolition of the not re-installed It will affect the center position drill. Taper, there is a total number of seven 0,1,2,3,4,5,6, taper value of certain changes in the nominal diameter 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, cutters) Various Arbor and the spindle taper. Taper is divided into long and short cone cone, long tapered multi-spindle hole for active machines, short taper for machine tool accessories and machine connection hole, short taper has B12, B16, B18, B22, B24 six models, they are based on long tapered 1,2,3 shortened from, such as B10 and B12 are long tapered at both ends of the size of No. 1, depending on the size and general machine tool accessory drive torque required to choose a short cone, such as the commonly used drill chuck 1- 13 mm usually with short taper B16, the test rods should be placed in clean and dry place for future use.
