Problems solved by technology

If domestic diamond rollers are used, new diamond rollers need to be replaced every time 500 to 1,000 blades are processed. However, domestic diamond rollers generally have a long manufacturing cycle and short service life, which cannot meet the processing needs of turbine blades.

Abstract

The invention discloses a processing method of a palm-shaped tenon, which is used for grinding the tenon of a turbine blade, including the following steps: S1 uses the first diamond roller whose tooth profile does not meet the standard to dress the first grinding wheel, and Use the first grinding wheel to roughly grind the tenon of the turbine blade; S2 After rough grinding, use the second diamond roller with a tooth profile that meets the standard to dress the second grinding wheel, and use the second grinding wheel to the tenon of the turbine blade Fine grinding is performed and the remaining machining allowance is ground. The invention can reduce the purchase cost of the diamond roller, prolong the service life of the diamond roller, and reduce the purchase frequency of the diamond roller.

Description

technical field [0001] The invention relates to the technical field of turbine blade processing, in particular to a method for processing palm-shaped mortise teeth. Background technique [0002] Turbine blades are an important component of the turbine section in a gas turbine engine. The blank of the turbine blade is made by casting. The blank of the turbine blade includes two parts: the tenon and the blade body. In the prior art, the palm-shaped tenon of the tenon is generally formed by grinding with a grinding wheel, and the contour tolerance of the palm-shaped tenon is The requirement is 0.03mm. [0003] However, the existing palm-shaped tenons are generally formed by grinding with a grinding wheel, and the grinding wheel is provided with grooves for forming the tenons. In order to ensure the profile of the palm-shaped tenons, it is necessary to use a diamond roller to dress the grinding wheel. If domestic diamond rollers are used, new diamond rollers need to be replace...
