Experiment on removal of remelting layer by turbine blades

In order to improve the cooling effect of the blades, the design of the gas film hole of the Blades is becoming more and more complex, and the cooling gas membrane hole machining of the turbine blades is the key to an important technology. Under the existing conditions, the processing of the gas film hole is further studied, and based on the theory of extrusion flow processing, the experimental method of extrusion flow grinding process is used to make the control aperture increase of the impeller cooling gas film hole so as to remove the remelting layer. When the aperture ø0.3 increase is 0.04 and the aperture ø0.5 increase is 0.02, the results of the remelting layer can be eliminated, which shows that the removal of remelting layer and microcracks by semi-solid abrasive has a very satisfactory removal effect.


Study on processing technology of deburring for hydraulic products

        As hydraulic products are moving towards high pressure, high speed, high power, low noise, high integration direction, and combined with a key model of our project to the small hole and long diameter is relatively large internal hole intersection deburring, to the inner hole oil tank and the long diameter comparison of the big hole transfer burr, To the complex shell parts of the deep hole intersection Burr and other two of the management of the project tackle。 Through the software abrasive deburring method, the technical problems of burrs at the intersection of the inner hole with large diameter and length are solved。 and summed up and spread horizontally, and easy to operate, high efficiency, low cost。
