The invention relates to a numerical control medium-speed wire cut electrical discharge machine, which can effectively ensure machining stability and machining dimension accuracy and reduce the running cost. The numerical control medium-speed wire cut electrical discharge machine comprises a wire cut electrical discharge machine. Closed loop control is performed on a wire feeding wheel and a wirewinding wheel in a wire feeding mechanism in the wire cut electrical discharge machine by a servo motor; a constant tension controller detects the tension of a wire electrode and controls the reversal of the wire feeding wheel and the wire winding wheel; the wire feeding wheel and the wire winding wheel form a U-shaped wire electrode tension traveling track by bottom guide wheels and a winding guide wheel; and a jewel positioner is positioned between the bottom guide wheel and the winding guide wheel at intervals. The machine has the advantages that: 1, the advantages of a step drive high-speed wire cut electrical discharge machine and a step drive low-speed wire cut electrical discharge machine are creatively designed, while the shortcomings of the step drive high-speed wire cut electrical discharge machine and the step drive low-speed wire cut electrical discharge machine are abandoned so as to realize the stable machining of machined work pieces and achieve high machining accuracy and low running cost; and 2, the jewel positioner effectively controls the running stability of molybdenum wires, and greatly improves the machining accuracy.
Description
technical field [0001] The invention relates to a numerically controlled medium-feeding wire-cutting machine which can effectively ensure the stability of processing and the precision of processing size, and can greatly reduce operating costs, belonging to the field of wire-cutting machine manufacturing. Background technique [0002] There are two types of wire-cutting mechanisms in the structural design of wire-cutting machine tools currently on the market: one is step-driven fast wire-cutting, and the other is slow-moving wire-cutting machine tools. Its disadvantages: Although the step-driven fast wire machine tool equipment in these two methods is low in price and low in operating costs, the processing is unstable and the accuracy of the processing size is poor; although the slow wire machine tool is expensive, the processing is stable and the size is low. High accuracy, but high operating costs. Contents of the invention [0003] Design purpose: To avoid the defici...
