(5) Smooth control of curved surfaces Due to the high requirements of the appearance of the cover product, and the need for mold forming and structural finite element optimization analysis meshing, the surface smoothness of the product is required to be good. In order to ensure the smoothness of t ....

Most machined surfaces must control microscopic geometry errors, ie surface roughness. Because it has a great influence on the performance and life of the part, in order to ensure the quality of the part, the surface roughness of the part must be assessed. There are currently two methods for assess ....

Our company is a high-tech enterprise specializing in the production of aluminum alloy automobile wheels. Since August 2000, our company has turned from motorcycle wheels to automobile wheels with broader market prospects. At present, the valve hole position of the automobile wheel, the position of ....

Traditional processes have always used EDM as the final finishing process for precision tooling. Its advantage is that the detection of the electrode before processing can better control the dimensional accuracy of the machined part, there is no hard interference during the processing, the heat dist ....

When grinding the valve root arc (Fig. 1), we need a positioner that can be positioned axially and radially, and can clamp the valve for grinding. In the past, we used the ordinary spindle tip sleeve to position the 60° inner cone surface and the valve disc end chamfer. The positioning accuracy ....

The metal cutting industry is a very important sector in the national economy, and it is inseparable from all walks of life. According to the statistics of 1988, the cost of cutting and processing in the United States is as high as 100 billion US dollars per year, of which the cost of cutting tools ....

In machining, it is often necessary to use a reamer for reaming. Especially when reaming with a new reamer, it is often caused by the tool. This is because the standard cylindrical reamer usually has a diameter of 0.005 to 0.02 mm. The amount of grinding, the roughness of the land is high, and can ....
