A Trusted Supplier for Aerospace Parts Manufacturing
United CGTR understands that quality and precision are paramount in a high-risk industry like aerospace.
We hope to be on your list of trusted Tier 3 suppliers for aerospace parts manufacturing. Here’s what Tier 2 aerospace suppliers can expect from our Connecticut shop when entrusting us with precision centerless grinding and thread rolling services.
In-House Precision Centerless Grinding and Thread Rolling
Our comprehensive in-house services ranging from centerless grinding and thread rolling to Swiss screw machining and wire EDM have earned us the reputation of being the precision machine shop’s one-stop shop. However, the capabilities most leveraged for aerospace parts manufacturing are centerless grinding and thread rolling.
Precision centerless grinding services
When you need straighter, rounder, and more precise-diameter aerospace parts, precision centerless grinding can deliver. The technique produces a “machined surface” that is impossible to achieve with a cutting tool in a conventional CNC turning process. We can reliably hold tolerances to +/- 0.00005”.
Thread rolling services
Thread rolling ensures the exceptional tensile, shear, and fatigue strength required for precision threaded aerospace components. Whereas thread cutting removes material by physically cutting away at a workpiece and weakening its structural integrity, thread rolling is a cold forging process that strengthens the material’s physical properties without removing any material.
United CGTR is adept at producing J-formed threads, which are ideal for critical aerospace applications where people’s lives depend on the threads’ functionality.
AS9100 Certification
We know that quality and on-time delivery are non-negotiable in aerospace parts manufacturing. Maintaining AS9100 certification helps us consistently deliver on both requirements.
Based on the scorecards filled in by Tier 2 aerospace suppliers who outsource parts to us, we’re proud to report that our on-time delivery rating is over 97% and our quality rating is nearly 100%.
Precision Specifications
Many aerospace parts have tight tolerances and precise concentricity and surface finish requirements. While it’s possible to achieve tight tolerances with conventional mills and lathes, the slow cycle times and dedicated manual quality assurance required aren’t cost-effective at high volumes.
Using precision centerless grinding, we can meet tight tolerance specifications easily and achieve concentricity and surface finish specifications that are impossible with conventional equipment. While many customers choose to send us a roughed-out piece for us to finish, we can also make your entire part from beginning to end.
Exotic Materials
Exotic materials like Inconel, Hastelloy, A286, and titanium are popular in aerospace parts manufacturing due to their desirable strength and temperature-resistant properties. However, these metals are anything but easy to cut using a mill or lathe.
When conventional CNC machining tools just can’t cut it (literally), precision centerless grinding is an excellent alternative. Whereas cutting tools used in conventional machining processes wear quickly and eventually break on hard materials, a grinding machine’s abrasive cutting wheels can handle even the hardest alloys. If the wheel dulls, we simply dress it to sharpen it—no need to pay for costly tool replacements.
Engineering Support
We’re always open to collaborating with our Tier 2 aerospace customers to help them adjust part designs for optimized manufacturing. For example, if you plan to machine blanks and send them to us for secondary processes, we can work with you to design blanks optimized for cost-effective and high-quality precision centerless grinding services.
