Embodiment Construction

[0023] The specific embodiment is to provide a kind of aviation turbine guide vane edge plate grinding method, which has the following steps: Step 1, grinding preparation

[0024] Fix the upper and lower edge plates of the guide vane; select the grinding wheel 1; correspond the annular right-angle groove 2 of the grinding wheel to the outer side 4 of the edge plate;

[0025] Step 2. Initial Grinding

[0026] First set the grinding parameters as follows: the linear speed of the grinding wheel is 30 m / s, the depth of cut is 0.4 mm, and the feed rate is 800 mm / min, and then the grinding is carried out;

[0027] Step 3. Adjust

[0028] Observe whether there are black spots at the grinding position on the outer side of the flange, and the level is 5 m / s. If there are black spots, reduce the linear speed of the grinding wheel by one level, and grind again when the depth of cut and feed speed remain unchanged; If there are no black spots, increase the linear speed of the grinding w...

Abstract

The invention relates to a grinding wheel for aeroturbine guide blade margin plate grinding and a grinding method thereof, in particular to a turbine guide blade margin plate grinding method being a high-speed forming grinding process for realizing improvement of the grinding efficiency and the grinding quality of a turbine blade margin plate. The grinding method comprises specific steps of grinding preparation, primary grinding, adjustment and circular grinding. An aeroturbine guide blade is a high-temperature alloy blade.

Description

technical field [0001] The invention relates to a grinding wheel for grinding the edge plate of an aviation turbine guide vane and a grinding method thereof, in particular to a grinding method for the edge plate of a turbine guide vane. Background technique [0002] The turbine guide vane is composed of four parts, the upper and lower edge plates, the left and right blade body, which are respectively connected together by vacuum brazing. Since the material of the turbine blade is a difficult-to-machine material, and there is a large deformation during the casting and welding process, there are problems such as severe wear, low grinding efficiency, and low linear speed of the grinding wheel when grinding the turbine guide blade, which is difficult to fully meet the production requirements. Require. Contents of the invention [0003] purpose of invention [0004] The purpose of the present invention is to provide a high-speed profile grinding process for turbine guide blad...
