1. During the operation of the rewinder, if the tool has a problem of lateral swing, it will lead to size problems. For example, the lateral swing and the outer diameter are different and not good, because the lateral swing value cannot be zero. Usually the lateral swing value of its load is about 0.03-0.05mm. The reason is the accuracy error of thickness, inner diameter, spacer sleeve width, etc., and the warpage caused by lateral stress when the thick plate is sheared.
2. During the production of the rewinding machine, due to the problem of lateral warpage of the steel plate, the width size is not good. This is because the product sheared in the transverse warped state is larger than the set value when measured.
3. Due to the production and operation of the equipment, there are corresponding matching errors in the spacer sleeves. When the number of cutters is large, the accumulated error becomes larger, which is due to the poor setting of the upper tolerance. It should be known that the width of the product cut by the rewinder is always slightly lower than the side dimension of the product. Therefore, it needs to be considered when confirming the size of the spacer sleeve when the knife is equipped on the product side.
