pipe mould processing problem: after adjusting quality from the deformation of tolerance, in the process of the broken bits, surface roughness price cut. The service life of the GuanMo mainly depends on the use of GuanMo state. The main technical parameters: material, surface roughness, precision, the coaxial tolerance, adjusting quality.
