Special screw

Special screw flat tail, that is, there is a lot of material at the tail that cannot be cut off. General analysis has the following reasons. First, the upper tooth groove of the elevation angle of the special screw is opened too wide and too deep, resulting in too much material feeding, which makes it impossible to discharge materials. Second, the angle of the back angle of the screw velvet is too small and there is too much material feeding. In these two cases, a gold steel file is used to push the back angle in the direction of the back angle, so that the back angle is increased and less material is fed, also, when adjusting the machine, loosen the teeth to make the tip of the head less?? Some materials can also be used, for example, the feeding end is loose and the forming area is tight, which can also solve the tailing problem;
