Aerospace forgings are high-precision designs in hard, high-value materials — meaning the cutting technologies adopted to finish them must be exceptionally strong, and reliable.

Simplifying Hard Material Cutting and Finishing

Aerospace forger adopts tools, coatings with bio-inspired surface technology to gain performance and reliability for precision finishing Nano-engineered materials Improving tool wear resistance Promoting dry/MQL machining

Wyman-Gordon is a forger that takes a very serious approach to high-quality finishing processes: its products are largely supplied to airframe and aerospace engine manufacturers for both the civil and military jet programs, and it maintains process and product quality accreditations for all of the major OEMs and tier suppliers.  Last fall, the Precision Castparts Corp. subsidiary started building a specialty finishing operation for aerospace forgings, in Dillon County, SC.

It produces closed-die forgings for rotating parts, as well as structural forgings for airframe, nuclear, petrochemical, power generation, and space applications.

Wyman-Gordon forges and finishes parts in high-grade titanium, nickel-based alloys, and stainless steels. These are parts for jet engines, including fan disks, compressor disks, turbine disks, and shafts. It also produces titanium and steel forgings for airframes, including wing beams, wing boxes, door and window frames, as well as nacelle and landing gear components. For all these reasons, Wyman-Gordon’s selection of cutting tools and wear parts bears close attention.

One supplier of those tools and coating formulations is NanoMech — a developer of “nanomanufacturing” technologies for mass production. It’s motto — “Making atoms work harder and smarter” — is an insight to its focus on material development and production process application.

Cutting and finishing hard materials like titanium, nickel alloys, and stainless steel calls for materials that are even harder. Doing it with reliable precision takes another level of innovation in material science.
