My company for deep hole boring and production equipment, production of single steel tube length can reach 12 meters, 180-630 - mm inner diameter, outside diameter, 220-820 - mm, wall thickness can reach 15-150 - mm, the equipment and technology to solve the large diameter hydraulic cylinder under the situation of unable to do cold drawn, deep hole machining of steel tube wall.
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.
Inner hole machining process: flat head, chamfering, rough boring, boring, boring, honing or rolling, pipe inner hole straightness of this process can reach 0.2 mm/m or less, basic can eliminate the processing technology of hot rolled tube wall thickness difference, is an important equipment of the production of large diameter hydraulic cylinder.
