Abstract
The invention discloses an electrolysis-mechanical micro cutting machining method of a fretsaw winding electrode, and belongs to the technical field of non-traditional machining. The method comprises the steps that two streams of electroplated diamond fretsaws of which the sections are in circular shapes are mutually twisted to form the electrode; the electrode can effectively improve the gap internal flow field state by using the concave-convex structure and high-speed spinning characteristic of the electrode, and new electrochemical reaction ions can be supplemented to a machining area in time; electrolytic products and passive films generated by electrolytic action are removed by the electroplated diamond fretsaws, and the machining quality and the machining efficiency are significantly improved; a plurality of grooves are formed by twisted wires, worn diamond particles in the machining process enter the grooves, therefore a plurality of worn particles are stored in the grooves, and more artificial diamond can be supplied for grinding. Accordingly, the chip removing performance can be improved, and the grinding performance, the cutting efficiency and the cutting quality are improved.
Description
technical field [0001] The invention belongs to the field of special processing, and in particular relates to an electrolytic-mechanical micro-cutting processing method for wire saw wound electrodes. Background technique [0002] The micro-cutting processing methods for metal mainly include: (1) precision mechanical cutting technology; (2) diamond wire saw cutting technology; (3) laser cutting technology; (4) plasma cutting technology; (5) fine abrasive jet cutting technology; (6) micro electric discharge wire cutting technology; (7) micro electrolytic wire cutting technology; (8) electrolytic-mechanical cutting processing technology. [0003] The essence of precision mechanical cutting technology is a process in which the processed metal undergoes shear deformation and separation due to shear force extrusion. The workpiece generates stress during processing, which is not suitable for processing thin workpieces, and the processing surface quality is poor, the noise is large...
