Electrolytic process characteristics

Electrolytic processing is the use of metal in the electrolyte occurs in the principle of electrochemical anodic dissolution of the workpiece forming a special
processing method. Processing, the workpiece connected to the positive DC power supply, the tool connected to the negative pole, maintaining a small gap between the poles. electrolysis
The liquid flows through the inter-electrode gap to form a conductive path between the two electrodes and generates a current at the power supply voltage to form an electrified
Learn anodic dissolution. With the tool relative to the workpiece continue to feed, the workpiece metal is constantly electrolysis, electrolysis products continue to be electrolyte red
Go, the gap between the final two poles tend to be consistent, the workpiece surface and the tool surface to form a shape similar to the basic.
Electrolysis has significant advantages for difficult-to-machine materials, complex-shaped or thin-walled parts. Electrolytic processing
Has been widely used, such as barrel rifling lines, leaves, the overall impeller, molds, shaped holes and shaped parts, chamfering and deburring
Other processing. And in many parts of the processing, electrolytic processing has occupied an important or even irreplaceable position.
Compared with other processing methods, electrolytic processing has the following characteristics:
(1) Processing a wide range. Electrolytic processing can process almost all conductive materials, and not subject to the strength of the material, hardness,
Toughness and other mechanical and physical limitations, after processing the material microstructure basically does not change. It is often used in machining hard
Metals, high temperature alloys, hardened steel, stainless steel and other difficult materials.
(2) high productivity, and processing productivity is not directly affected by the processing accuracy and surface roughness. Electrolytic processing can be Jane
A single linear feed motion to the complex processing of the cavity, profile and the type of hole, and the processing speed can be compared with the current density
Example increase. According to statistics, the production rate of electrolytic machining is about 5 to 10 times EDM, in some cases, even
To exceed the mechanical cutting.
(3) processing quality is good. Can get a certain degree of processing accuracy and low surface roughness.
Processing precision (mm): the surface and cavity is ± 0.05 ~ 0.20; type hole and nesting material is ± 0.03 ~ 0.05.
Surface roughness (μm): for the general medium and high carbon steel and alloy steel, can reach Ra1.6 ~ 0.4 steadily, some alloys
Steel can reach Ra0.1 [1].
(4) Can be used for processing thin-walled and deformable parts. Electrolytic processing tools and workpieces do not touch, there is no mechanical cutting
Cutting force, does not produce residual stress and deformation, there is no flash burr.
(5) tool cathode lossless. In the electrolysis process, the cathode of the tool is only precipitated hydrogen without dissolution reaction,
So there is no loss. Only in the event of sparks, short circuit and other anomalies lead to cathodic damage.
