The traditional turning processing steps are mainly divided into rough processing and finish processing, but after the rhombic cutting head is processed, spiral tool marks with small intervals are still formed on the surface, fine needles or nails are scraped, obvious setback feeling is achieved, circular grooves formed by spirals are the main reason of dirt deposition, therefore, manual grinding is needed until the brightness of the mirror surface is high, and better pollution prevention can be achieved.
If the method is applied to high-pressure sealing of power equipment and local high-field-intensity parts, the surface roughness of a workpiece after finish turning cannot meet the technical requirements, polishing treatment is still carried out after finish turning, and surface cleaning treatment (water washing or ultrasonic cleaning) is carried out after polishing treatment.
In terms of production and manufacturing, an additional working procedure is needed for polishing, so that the processing efficiency is influenced, and the manufacturing cost is indirectly increased; in addition, because of the characteristics of metal materials, particularly the aluminum alloy surface is easy to adsorb dirt, a large amount of cleaning agents and passivating agents are needed for cleaning, extra sewage treatment cost is needed to be increased, and in addition, a large amount of chemical cleaning agents are avoided as far as possible from the consideration of environmental protection.

Fig. 3, 4 and 5 are block diagrams of tools used in the finishing process of the prior art.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
The invention discloses a turning method of an aluminum alloy workpiece for an SF6 high-voltage electrical appliance, which is used for processing an aluminum alloy workpiece for an SF6 high-voltage electrical appliance, and comprises an aluminum alloy cylinder, a flange, a conductive rod and a conductive connector for GIS/GCB, wherein the turning method comprises the following steps:
1) rough turning: turning an aluminum alloy workpiece for the SF6 high-voltage electrical appliance;
2) finish turning: and after the rough turning is finished, performing finish turning on the surface of the roughly turned SF6 high-voltage electric appliance aluminum alloy workpiece by using a cutter with an arc-shaped cutting head made of diamond.
The invention provides a novel turning method, wherein the first step is rough turning which is the same as the traditional method; and secondly, finish turning is carried out, the cutter is changed, the cutter with an arc-shaped cutting head is adopted, the cutter head is made of diamond, and the cutting head of the cutter head is not in a conventional rhombus shape but in an arc shape with a radian.
The cutter in the finish turning step comprises a cutter head 31, a cutter bar 32 and a cutter handle 33, wherein the cutter head 31 is made of diamond, a cutting head of the cutter head 31 is in an arc shape, the cutter head 31 is welded on the cutter bar 32, and the cutter bar 32 and the cutter handle 33 are integrally formed.
The cutting head in the cutting head 31 has an arc range of 0.5 mm-30 mm.
The invention adopts the cutter with the arc-shaped cutting head to finish turning the surface of the aluminum alloy workpiece for the SF6 high-voltage electrical appliance, continuous turning is formed by arc-shaped smooth transition of the cutting line, and the grinding effect of the cutter back angle of the diamond cutter head can form a mirror surface effect, dirt is not easy to store, and only wiping is needed after cleaning. In addition, the cutter of the diamond cutter head is suitable for dry cutting, cooling liquid is not needed for auxiliary heat dissipation, the pollution chance is reduced, and the cleaning of the workpiece is more convenient.
Because the diamond has hardness far higher than that of an aluminum alloy workpiece (copper and aluminum alloy) for an SF6 high-voltage electrical appliance, a grinding and polishing effect is formed on the surface of the part after the small circular arc-shaped cutting head is adopted, so that the surface of the part achieves a mirror-like smooth effect; therefore, the parts processed by the technology do not need manual polishing, the surface roughness and the compactness of the parts are far higher than the effect of the prior manual polishing, and the parts are directly washed by clear water or wiped by alcohol without using a large amount of cleaning agents and passivating agents in the later period of cleaning.
By adopting the method, the production efficiency of the product can be improved, and the production and manufacturing cost can be saved; and from the aspect of environmental protection, not only water resources are saved, but also pollution possibly caused by using a chemical cleaning agent is avoided.
In order to solve the slight knife crease line after the work piece is processed, a round tool bit cutter made of diamond is finely turned, and the diamond tool bit has high hardness, so that the cutting head of the cutter is round, the cutting and rolling effects are achieved during the processing, the surface of the turned work piece is similar to a mirror surface effect, no visible texture exists, and the work piece does not need to be polished again in the later period; in addition, the compactness of the surface of a product is greatly improved by rolling the round cutting head, and the cleaning work at the later stage is very simple for the aluminum alloy workpiece and can be directly washed by water or wiped by alcohol.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
