Nowadays, with the increasing emphasis on burr removal in various industries,stayCNCAlthough the burrs in precision parts processing are not very small,But it directly affects the quality of the product, so,There are also endless methods for deburring。Electrolytic deburring is suitable for removing burrs from concealed cross holes or complex shaped parts in parts,High production efficiency,Deburring time usually only takes a few seconds to tens of seconds。This method is commonly used for gears、spline、connecting rod、Deburring of valve body and crankshaft oil passage holes, etc,And sharp corner rounding, etc。The disadvantage is that the vicinity of the burrs on the parts is also affected by electrolysis,The surface will lose its original luster,Even affecting dimensional accuracy。
The commonly used trimming nowadays / There are mainly several types of deburring:
1. The traditional method of manual deburring is a steel file,Sandpaper,Grinding head polishing;And the trimming knife gradually replaced these traditional methods,Easy and convenient to use,No technical processing required,Cost saving and environmentally friendly。
2. Chemical deburring。Using the principle of electrochemical reactions,Automatically process parts made of metal materials、Selective completion of deburring operations。It can be widely used in aerodynamics、hydraulic pressure、construction machinery、Oil nozzle oil pump、automobile、Pump bodies made of different metal materials in industries such as engines、valve body、connecting rod、Deburring Processing of Plunger Needle Valve Coupled Parts and Other Parts。Suitable for internal burrs that are difficult to remove、Parts after heat treatment and precision machining。
3. Electrolytic deburring An electrochemical machining method for removing burrs from metal parts using electrolysis,English abbreviation ECD 。Insert the tool cathode(Generally, brass is used)Fixed and placed near areas with burrs on the workpiece,A certain gap between the two(Generally, it is 0.3 ~ 1 millimeter)。Align the conductive part of the tool cathode with the burrs and edges,Cover other surfaces with insulation layer,Concentrate electrolysis on the burrs。During processing, the tool cathode is connected to the negative pole of the DC power supply,The workpiece is connected to the positive pole of the DC power supply。Pressure is 0.1 ~ 0.3 Low voltage electrolyte in megapascals ( Generally, sodium nitrate or sodium chlorate aqueous solution is used ) Flowing between the workpiece and the cathode。After connecting the DC power supply,Burrs will undergo anodic dissolution and be removed,Taken away by electrolyte。Electrolyte has a certain degree of corrosiveness,After deburring the workpiece, it should be cleaned and treated with rust prevention。
