Understand the range of honing tube properties

      Therefore, honing is a processing process through which the inner hole of the pipe is brought to the expected tolerance size, as well as the surface roughness, etc., and is within the tolerance range.
       
          The inner hole roughness of the honing tube can be less than 0.63nm, and the linear standard can be less than 0.3mm/m. Therefore, it can have a higher level of dimensional accuracy. Therefore, it can be used in some demanding situations. And its honing requires the use of a honing machine. Generally speaking, the honing head on the honing machine performs axial linear reciprocating motion.
