Embodiment Construction
[0014] The present invention is a roller bar lathe one-time molding process. The currently used process is bar feeding. The six-meter bar is loaded to the reference size, clamped by the workpiece shaft, and the servo controls the end face knife feed on the DF3 lathe. Make a flat end face on the right end face of the bar. After the flat end face reaches the specified size, dig a center hole on the right side of the roller through the end face knife to form a hole once. The servo controls the feed of the cutting knife to cut the roller. The copying knife copies the outer diameter of the roller and the chamfers on both sides, from right to left. After the copying is completed, the cutting knife still feeds. When the diameter of the center is 2.5 mm, the knife is retracted. After the lathe The end clamping device feeds and grabs the roller, the workpiece shaft continues to rotate, the roller and the bar form a relative rotation, the roller is twisted, the clamping device is retract...
