Analysis of technical problems of deburring machine effect.

Deburring machining is a processing method that uses the principle of anode dissolution of metal in the electrolyte to remove excess material on the workpiece. At the beginning of the deburring machine, the shape of the workpiece anode and the tool cathode is different, and the distance between the points on the workpiece surface and the tool surface is different, so the current density of each point is different. The current density at the close distance is large, the flow rate of the electrolyte is often higher, and the speed of the anode solution is faster. On the contrary, the current density passing through the distance is small, and the speed of the anode solution is slower. When the tool is continuously fed, the points on the surface of the workpiece are dissolved at different solution speeds, and the shape of the workpiece is gradually close to the shape of the tool, until the shape of the tool is "mirrored" on the workpiece, and the desired shape is obtained.

Deburring machine equipment electrode and workpiece processing gap problem.

Machining gap is one of the main factors affecting the machining accuracy of deburring machine, and it is also the main basis for designing tool cathode and selecting process parameters.

Electrolyte problem of deburring machine equipment.

The main function of the electrolyte is: as a conductive medium to transfer current; The electrochemical reaction is carried out under the action of electric field, so that the anodic dissolution can be carried out smoothly and controlled. The electrolytic products and heat generated in the processing gap are taken away in time, and the role of updating and cooling is played. Therefore, the basic requirements of the electrolyte should have the following points:

High conductivity and specific heat capacity; Low viscosity to reduce the electrical energy loss and heat generation caused by the resistance of the electrolyte, and make the electrolyte in the processing gap have sufficient flow rate; Safe, non-toxic, less corrosive; Stable composition, easy maintenance, low price. With good processing characteristics, the workpiece material can be evenly dissolved at high speed, and the formation of insoluble passivation film can be avoided as far as possible; Metal cations in the solution must not be deposited on the surface of the tool cathode to maintain the correct shape of the tool cathode profile.
