mechanical method
With the help of an industrial manipulator, a rotating wire brush or grinding wheel is clamped, and the burr is polished by the joint arm movement of the manipulator to remove the burr. The manipulator can select wire brushes or grinding wheels from the racks of the tool magazine, which are suitable for deburring on different parts of the part. However, this method is often not suitable for use in many occasions because the arm joints of the manipulator lack sufficient rigidity and precision. Moreover, due to the different structures of the parts, some parts cannot be deburred by this method, and other deburring equipment has to be equipped.
vibration method
This is designed for deburring smaller parts of revolution or diamonds. Parts are placed in a large container filled with a granular ceramic medium that varies in size depending on the type, size, and material of the burred part. The rapid reciprocating vibration of the container makes each part of the part move and rub against the ceramic medium to remove burrs and polish the surface of the part. The intensity of vibration can be adjusted to suit parts of different sizes.
Thermal energy method
The process of thermal deburring is the process of oxidation into powder at high temperature. The thermal deburring machine seals the burred parts in a container filled with high-pressure combustible gas mixed with oxygen. The burrs on the parts are surrounded by this mixed gas, no matter in the outside, inside or in the blind hole position. After the spark plug ignites the gas mixture, it generates an instantaneous high temperature heat wave. Because the ratio of surface area to gas of the burr part is quite high, the burr burns, and in the cycle time of 15 to 30 seconds, the burr is continuously oxidized and transformed into powder, and then clean the workpiece with solvent.
This method is the only uniform deburring method that removes unwanted material from all parts from their surfaces, even from hard-to-reach internal grooves and intersecting holes, and afterwards No need to check. Therefore, it is widely used in the deburring process of ferrous and non-ferrous metal parts.
Electrochemical method
Electrochemical (also known as electrolysis) deburring machine removes burrs on parts by dissolving metal materials from parts into electrolyte through electrochemical reaction. The tool electrode is connected to the negative pole of the DC power supply, the parts with burrs are connected to the positive pole of the power supply, the electrolyte of a certain pressure and flow rate is passed through the middle, and then the DC power supply is connected, so that the metal used as the anode gradually undergoes electrochemical dissolution to achieve removal. Burr (or molding) purpose.
Electrolysis effectively removes burrs of any size with high quality. During the processing, since the tool electrode (cathode) is not worn and its position can be fixed, the operation is very simple, the productivity is high, and it is suitable for automatic processing; no thermal stress and mechanical stress are generated during the process, and the workpiece will not be deformed; A wide range of materials and hardnesses can be used.
