Abstract

The invention belongs to a precision casting technology, and relates to a method for controlling the dimensional precision of a guide blade of a zero-allowance precision casting turbine. The method is characterized in that the method comprises the following steps of: controlling the precision of the profile size of the guide blade; and (4) controlling the precision of the size of the exhaust edge of the guide vane. The invention provides a method for controlling the dimensional accuracy of a guide blade of a zero-allowance precision casting turbine, which considers the influence of subsequent treatment on the size of the blade, ensures that the dimensional accuracy of the guide blade meets the design requirement, shortens the shaping period of a guide blade mould, and ensures the quality consistency of the guide blade.
