Tolerance Masters completed the construction of a series of exhaust deflectors, employed by the power generation industry to deflect exhaust within a power generation application. A complex series of machining processes was required in order to successfully manufacture each unit. This twenty step process included numerous CNC live tool turning operations, two 5 axis milling operations, and three special finishing processes: heat treating, passivation, and nickel plating per Mil-DTL-26574 specifications.
We constructed each part using a Greek Ascoloy per AMS5616 base material, a substance that is considered a high temperature grade alloy. Due to the critical nature of this material specification, a material test lab report had to be validated against every certified lot. Moreover, due to the close tolerance dimension of this part, custom designed insert tooling had to be applied in order to successfully form the trepan area and undercut face curve geometry from the flange.
Through the application of over twenty complex machining and finishing processes, Tolerance Masters was able to successfully build a series of exhaust deflectors that could be affectively used by the power generation industry.
