Honing the hydraulic cylinder is in of the inside hole by blank hot-rolled tube processing, key performance indicators are: such cylinder material, tensile properties, yield strength, elongation, surface hardness, diameter tolerance, inner hole, inner hole straightness, roughness material usually have 20 #, 45 #, 16 mn, ST52, such as material, the whole steel tube do heat treatment is to stress relieving, outer surface with acid pickling phosphating after anti-rust oil daub antirust processing, is done in the large deep hole boring cutter adopts: rough boring cutter, half fine boring cutter, boring cutter, rolling cutter head combined four monomer, rolling pressure head at the last surface under stric extrusion molding, to achieve expected diameter size tolerance, inner hole surface of high strength, high degree of finish, high resistance to wear.
