Abstract
Provided is a high-speed arc discharging and grinding combined machining method. Arc discharge can be formed by adopting electrode side faces, a grinding layer is arranged at the bottom of a tool electrode, and high-speed arc discharge machining is combined with grinding. Removal of materials and combined machining of finishing are realized in a process with the help of multiple energy fields, andnot only can high-efficiency and low-cost machining of materials which are difficult to cut be achieved, but also the problem of poor surface quality after machining during the arc discharge machining can be effectively solved. High-efficiency, low-cost and high-precision machining of various conductive materials is realized through a piece of equipment.
Description
technical field [0001] The invention relates to conductive materials, in particular to a high-speed arc discharge grinding composite processing method for conductive materials. Background technique [0002] High-speed arc discharge machining is a new machining method specially proposed for the urgent needs of high-efficiency and low-cost machining of difficult-to-cut materials. The principle is to use the high temperature of the arc plasma generated by the discharge to quickly melt or even vaporize the workpiece material, and cooperate with the high-speed flow field between the tool electrode and the workpiece to quickly flush the etched material out of the gap. This method is especially suitable for those with Machining of difficult-to-cut materials with certain conductivity. However, due to the extremely high energy density of the arc, in order to achieve the purpose of high efficiency, the energy of each discharge pulse is also very large, which results in large corrosio...
