Quality requirements of precision honing pipe manufacturers
The prior art hydraulic drawing machine drawing only ordinary precision honing tube, pipe manufacturing high-precision, must be ground. Existing technology uses a method of forced lubrication extubation, although the pulling force can be reduced, but there are prone to leakage of the lubricant, the lubricant film difficult to establish a stable, pipe surface quality and poor lack Dian. The present invention provides a flexible hydraulic cylinder tube method, deformation of the metal is not in contact with the mold formed by the mold - hydraulic oil - Tube - hydraulic oil - a flexible core head deformed state, thereby greatly enhancing the accuracy of cold drawn tubes. 1, Wear: Precision honing tube manufacturers lined ceramic layer Al2O3 content greater than 95%, hardness HV1000--1500, which has high wear resistance, the wear resistance than carbon after quenching steel high ten times better than tungsten carbide drill. 2, The corrosion resistance of the ceramic material is a...
