Taper shank test rod: (0#-6#) Standard straight rod (mandrel) is manufactured according to JB/T9881-99 standard, used to test the geometrical accuracy of various machine tools, made of carbon tool steel, processed after multiple heat treatment The working surface is precisely ground.
Taper is a standard for taper for static fit to position. Due to the small taper, the principle of friction can be used to transmit a certain torque, and because it is a taper fit, it can be easily disassembled. Within a certain range of the same taper, the workpiece can be freely disassembled and assembled, and at the same time, it will not affect the use effect during work, such as taper shank drill for drilling. If it needs to be disassembled for grinding, it will be reinstalled after disassembly. Will affect the center position of the drill bit.
