Page 74: Procedure To Follow If The Tool Becomes Jammed In The Piece Being Machined
If this procedure is not followed, the tool holder will drag the locking system (collet/screw dowel) with it until the cone is released. After which, the collet will move back violently due to the force exerted by the spring and could cause damage to the screw dowel. HSD S.p.A. © - 0106h03a.fm100713...
