Hi! Material of the screw is steel 35 (i.e. 0.35% of carbon) Tolerance: for a billet +/- 0.15 mm; precision with which a billet should be put into the stamp: 0.1 mm A billet must be heated to the temperature of 1200 degrees Celsius, no heat treatment is expected. No requirements for the hardness. UT test is not needed. The cycle of stamping is 5 seconds, of which 2 s for the press work, 3 s for the robot-manipulator work. Price limits: USD 40 000 for robot-manipulator, USD 50 000 for press. The screw is absolutely ready after stamping and thread rolling, no additional operations are expected.
