CNC Machined Alloy Steel Tie Rod for the Power Generation Industry

At Accurate Threaded Products, we specialize in precision CNC machining services. A customer in the power generation industry contracted us to produce this alloy steel tie rod used in an industrial gas turbine engine. Due to our quality work and reliability, we are the only approved manufacturer of this part. The rod is produced by turning raw Inconel stock on a CNC lathe and then milling the piece in our vertical milling center. Threads on the ends are produced by thread rolling. The rod is finished using centerless grinding to produce a superior shape and a surface finish of 62 RMA, and then heat treated to customer specifications. The finished part measures 1.276" in diameter and 23.600" long with dimensional tolerances as tight as ±0.0005".

Rods undergo extensive testing including dimensional inspection, hardness, FPI, and tensile testing. Our quality management system is ISO9001:2008 and AS9100C certified, and we can meet any applicable industry standards and customer specifications. For this project, 200 of these tie rods were produced with a lead time of six months. For more information about this CNC machining project, see the table below, or contact us directly.
