Embodiment Construction
[0016] Embodiments of the present invention: with figure 1 Take this as an example.
[0017] 1. Material preparation: choose 6A02-T6GB / T3191-1998 aluminum alloy bar.
[0018] 2. Turning processing:
[0019] (1) The outer circle φd2 end of the hard three-jaw clamp, turn one end face, drill, turn the center hole and the threaded hole, the tailstock thimble presses against the center hole, rough turn the outer circle φd1, and leave a margin.
[0020] (2) The outer circle of the soft three-jaw clamp is φd1 at the end of the car, and the center hole is drilled at the other end of the car, the tailstock thimble is pressed against the center hole, and the outer circle of the rough car is φd2, leaving a margin.
[0021] (3) The soft three-claw clamps the outer circle φd1, the tailstock thimble pushes against the center hole, semi-finishes the outer circle φd2, leaves the margin for finishing turning on the outer circle, and turns the ring groove of the φd2 section to the requirement...
