This very small part was produced by the experts in our AS9100-certified Swiss precision machining division, where tight tolerances and fine details are part of everyday work. Swiss machining allows us to hold exceptional accuracy on small diameter parts, complex geometries, and long length to diameter ratios, even in challenging materials.

It is an ideal solution for components that demand consistency and repeatability at scale.

If your next project calls for precision at this level, we are here to help. Contact us to request a quote today.

Our CNC profile grinding process sets a high standard for precision and surface finish by holding an entire profile on a single grinding wheel without withdrawing from the workpiece.

This continuous approach eliminates transition marks, delivers tolerances as tight as ±0.00005”, achieves radii down to .002”, and produces surface finishes as smooth as 16 Ra right off the machine: twice as smooth as typical industry standards.

Swiss machining is widely known as a fast, cost-effective solution for precise parts. Historically, though, many buyers associated Swiss work with more easily machineable materials like aluminum. They assumed that harder, high-strength materials belonged on other equipment.

But the limiting factor is rarely the Swiss machine itself. Materials like nickel-based superalloys, cobalt alloys, and tough stainless steel grades can be machined on Swiss equipment, but they require a higher level of process control.

At UCGTR, our Swiss machining arm has been in operation for more than 25 years. Learn how that experience and expertise allow us to handle your Swiss machining projects from bar prep to finishing: https://bit.ly/3MCWYD7

When your parts need tight tolerances and consistently precise diameters, our centerless grinding services deliver. At United Centerless Grinding & Thread Rolling, our centerless grinding process handles everything from simple cylindrical pins to complex multi-diameter shafts, stepped or conical profiles, and long bar or tube stock, all with tolerances down to ±0.00005".

Whether you need thru-feed grinding for high-volume production, form grinding for intricate shapes, crush grinding for multi-diameter profiles, or bar grinding for oversized stock, we’ve got the tools and experience to get the job done.

At United Centerless Grinding and Thread Rolling, we're ready to tackle Swiss machining projects for challenging materials like A286, Inconel, 17-4 stainless steel, and more.

By combining Swiss with other complementary capabilities, both upstream and downstream, tough materials become far more manageable. Instead of sending work to multiple suppliers for prep, machining, and finishing, you can keep more of the processes with the same partner at UCGTR. Learn how this can simplify your next project: https://bit.ly/3MCWYD7

This long, thin part features rolled threads that deliver outstanding tensile, shear, and fatigue strength. Our team uses precision thread rolling to create consistent, high strength threads in both standard and metric pitches. We support sizes from number 0 to one and one eighth inches and thread lengths up to four inches long, along with J form, metric, left hand threads, knurling, and even threads that require destructive lab testing.

If you need strong, reliable threads for your parts, we are here to help. Request a quote today: https://bit.ly/3JRbyTT

Some parts just don’t play nice in traditional machining—long shafts, oversized diameters, or ultra-thin walls. That’s where our bar grinding and thru-feed grinding capabilities shine.

At United Centerless, we grind bars up to 30 ft long and diameters up to 5.75″, with tolerances down to 0.0002" if needed.

We also handle thin-wall tubes with wall thicknesses as low as .015" (for smaller diameters) and even straighten bent stock mechanically—all while maintaining roundness, straightness, and dimensional integrity.
