The insiders in the industry should know that the jig sheet of the winding machine is the basis for the numerical control winding machine to conduct winding, and the jig sheet of the winding machine is the bridge between the winding machine and the user's requirements for the coil. Both the purchaser and the operator of the winding machine must understand that the winding machine can do nothing without the clamping piece of the winding machine that has been strictly designed and processed. Therefore, the technical content of a winding machine manufacturing enterprise is not always measured by how well the winding machine is made and how beautiful the appearance is. These are imaginary. In fact, for users, a winding machine capable of winding qualified products is what they need most.
