Method of the Remanufacturing Machining Benchmark of Gas Turbine Secondary Guide
摘要
Abstract
In view of the complex shape of gas turbine secondary guide,poor machining quality and low production efficiency caused by multiple conversion of machining benchmarks,a method of remanufacturing machining benchmark is proposed:searching for a low-melting point alloy formula and designing the corresponding mold to realize the orientation of the guide in the mold,and pouring a regular-shape alloy block around as machining benchmark.The target alloy has a low melting point,good liquid fluidity,and high stiffness after solidification to ensure the stability of clamping and high brittleness to ensure that it can be broken and disengage the guide.The optimized mold can ensure the accuracy requirements of the guide orientation and the machining,also can avoid casting defects.关键词
