The Processing Electrode Of EDM Based On SLA Prototype And Chemistry Plating Copper Craft Makes Technical Research

It is a request of the shouldering type of the straight type according to the real part, making technology of the electrode that this text has studied the electric spark based on SLA prototype and silicon rubber mould and taken shape emphatically, to what prototype surface and silicon rubber mould surface in SLA to carry on the copper-plated craft of chemistry and method and carry on deep research especially. Pass to the copper-plated mechanism of chemistry, the analysis and studying of thermodynamics condition, motive force knowledge question, has confirmed that carries on the copper-plated feasibility of chemistry on prototype surface of SLA and silicon rubber mould surface. Is it pay test method study chemical copper facing main salt in the prescription, hold mixture, stablizer, additive in place with a net to deposit speed and influence, solution of stability to use, confirm chemistry initial copper facing solution and chemistry accelerate copper facing solution optimization is it is it sink copper speed and stability of the solution raise in step to make to fill a prescription most.The performance of layer of copper that this text still deposits to chemical copper facing is like the external appearance, metallurgical structure, bond strength, chemical copper facing result of plating ability, micro- hardness, porosity and narrow groove have carried on detailed test and analysis, and has carried on preliminary discussion and experiment to the chemical copper facing of the alternative.On the basis of the thing that make good result in prototype surface of SLA and silicon rubber mould surface chemistry copper facing , set about solving SLA prototype and silicon rubber mould and stripping the craft and method through a large number of tests. Especially to the stripping of SLA prototype , use the similar principle similar to solubility parameter of principle of polarity, have confirmed that corrode and destroy the organic solvent of SLA prototype , thus the difficult problem stripped after solving the chemical copper facing of SLA prototype effectively.Finally, and strip on the foundation with ripe craft in chemical plating copper , trial-produce the craft method of the copper electrode of EDM through the detailed introduction of the instance , thus formed the technological routes of a set of more intact making electric spark electrodes, have offered a kind of method that can bedrawn lessons from for processing of the electric spark electrode.
