The rolling cutter can realize rough boring, semi-fine boring, fine boring and rolling of the inner hole of the cylinder barrel at one time. The production efficiency is greatly improved, which is more than 10 times that of the traditional honing processing method. Achieve the mirror effect of the inner wall of the cylinder (Ra=0.03um~0.2um).
Because the surface layer retains surface residual compressive stress, it helps to close the surface micro-cracks and hinder the expansion of corrosion, thereby improving the surface corrosion resistance, and can delay the generation or expansion of fatigue cracks, thereby improving the fatigue strength of the cylinder.
The rolled surface can form a cold work hardening layer, which improves the wear resistance of the inner wall of the cylinder. Effectively avoid burns caused by traditional grinding processes.
