BURRING APPARATUS FOR FRICTION WELDING MACHINE

摘要

A burring apparatus for a friction welding machine comprises a clamp unit provided at the front end of a horizontal main spindle, for holding work piece W1 coaxial with the main spindle, a clamp unit provided at the front end of a slide movable to and away from the main spindle in the direction of the axis of the main spindle and a doughnut-shaped cutter for shearing off a burr. Work piece W2 is moved forward together with the slide until work piece W2 comes into contact with work piece W1 so that the mated ends of work pieces W1 and W2 are friction welded together to form a joint work piece W. The burr formed on the jointed work piece W is sheared off by the cutter. The jointed work piece W is then liberated from the main spindle.
