Abstract

The present invention discloses a kind of electric spark forming machine for processing non-conductive hard material and its processing method. The forming machine includes a work table, a work solution tank on the work table for holding circular work solution, an insulating pedestal for holding workpiece and set inside the work solution tank, a pair of discharge electrodes set in the processing site, submerged inside the work solution tank and with micron level gap in between, and a pulse power supply with two poles connected separately onto the electrodes. The processing method is that inside the liquid medium, the workpiece is cut through serial pulse discharges. The present invention has simple machine equipment and stable processing.

Description

technical field [0001] The present invention relates to a kind of electro-spark machine tool and its processing method for processing non-conductive hard materials, specifically, in liquid medium, adopt the method of a series of rapidly repeated pulse discharges between two electrodes to remove workpiece material mechanical method. Background technique [0002] Non-conductive hard materials such as non-conductive engineering ceramics have broad application prospects in modern high-tech fields due to their excellent performance, but these materials generally have extremely high hardness and high brittleness, and it is very difficult to process them , which considerably limits the applications of these materials. [0003] At present, the machining method of these non-conductive hard materials is mainly the diamond grinding wheel grinding method, but this method is generally limited to the processing of flat and simple curved surfaces, and the cost of diamond grinding wheels i...
