When the ordinary double-head saw is fixed to length, it is manually operated, and the movable head is pushed to the required size position, and then After fine-tuning to the required size, lock the movable machine head. As for the length cutting accuracy, the CNC error is within 0.2 mm, and the length cutting error of the ordinary double-headed saw is withi......
