Swiss Machining
Precision Swiss-turned aerospace parts on Tsugami B0386-III and B0205-V lathes — AS9100 and ITAR-registered for tight-tolerance shafts, pins, connectors, and threaded parts.
What Is Swiss Machining?
Swiss Machining is a precision turning process that uses a sliding headstock and guide bushing to cut small, complex parts with tight tolerances. As a result, EGM Manufacturing runs two Tsugami lathes — the B0386-III and the B0205-V — for aerospace shafts, pins, connectors, and threaded parts. Every part meets tight aerospace needs.
Swiss Machining from EGM Manufacturing delivers small precision parts built for aerospace and defense programs. Our team reviews every CAD file to confirm the part can be made. We run the job on our Tsugami B0386-III or Tsugami B0205-V lathes with live tooling and sub-spindle work. Our AS9100 and ITAR-registered shop in Sunrise, Florida supports buyers who cannot accept runout drift or late delivery. Our Swiss cell handles threading, grooving, milling, and back-work in one setup. With no volume minimums, EGM scales from one prototype to 1,000+ units.

Why Swiss Machining Matters for Aerospace and Defense
When a small rotating part fails in a flight or defense system, the result is total loss of function. Therefore, aerospace and defense buyers demand Swiss Machining done inside a certified quality system. Moreover, guide bushing support holds tight runout on long, slender parts that standard lathes cannot cut without deflection. A Swiss-turned part that holds true concentricity and clean threads makes sure the assembly is safe and steady under load. Plus, EGM runs every Swiss job inside the same quality system used for milled and turned work — so paperwork stays in one place. For teams that also need larger milled parts, our multi-axis CNC milling services link up naturally.
What Is the Difference Between the Tsugami B0386-III and B0205-V?
The B0386-III handles larger bar diameter — up to 38 mm with guide bushing and 42 mm in chucker mode — and offers 29 tool positions with Y2 axis live tooling. The B0205-V is a 20 mm Swissturn built for higher-speed small parts, with a 10,000 rpm main spindle and 12,000 rpm back spindle. Buyers pick based on part size and volume.
How Our Swiss Machining Process Works
Every Swiss Machining job at EGM follows a clear workflow. First, your team submits CAD files, 2D drawings, and material specs. Next, our engineers review the package, confirm the part can be made, and plan tooling paths. Then, the job goes to the right Tsugami platform — B0386-III for parts up to 38 mm bar, B0205-V for parts up to 20 mm bar. After that, our CMM checks key dimensions against print — including runout, thread pitch, and cross-milled features. Finally, we ship with full paperwork.

What Materials Does EGM Swiss-Machine for Aerospace Parts?
EGM routinely runs aerospace-grade aluminum alloys like 6061, 6061-T6, 6082, and 7075. Plus, we cut stainless steels like 303, 304, 316, 17-4, 420, and 2205 duplex. Moreover, we work titanium, brass, copper, alloy and tool steels, plus plastics like PEEK, PTFE, Delrin, UHMW, and G-10. Custom materials get case-by-case review.
Aerospace and Defense Applications for Swiss Machining
EGM’s Swiss Machining work produces small precision rotating parts common in aerospace and defense assemblies — shafts, pins, connectors, and threaded parts within the 20 mm and 38 mm bar-capacity range of our Tsugami platforms. Plus, our sub-spindle and live tooling handle back-work, cross-holes, and milled flats in one setup, so parts finish complete off the machine. Thread whirling and polygon machining are available on the B0386-III for specialty features. In every case, each job ships with check reports, material certs, and full tracking. For examples of recent work, browse our product gallery.
What Tolerances Can EGM Hold on Swiss-Turned Parts?
Our standard machining limit is ±0.005″ on metals and ±0.010″ on plastics. Plus, our fine tolerance holds ±0.0002″ on metals and ±0.005″ on plastics. Both Tsugami platforms feature 0.1 micron axis resolution, backing consistent Swiss work. For tighter custom specs like runout and true position, we review the 2D drawing case by case.
Choosing the Right Swiss Machining Partner
Picking a Swiss supplier is a risk choice. A failed pin, bad-threaded connector, or out-of-round shaft can stall an entire aerospace program. The right Swiss Machining partner holds current AS9100 certification, carries ITAR registration, shows safe handling of controlled data, and runs production-grade Swiss-type lathes. Above all, EGM Manufacturing checks every one of those boxes. Plus, we back every Swiss batch with check paperwork, material certs, and a 50+ year combined machining track record trusted by aerospace primes and tier-one defense firms.
Does EGM Offer Finishing Services on Swiss Parts?
Yes. EGM offers anodizing, powder coating, bead blasting, polishing, brushing, heat treating, passivating, plating, painting, screen printing, and laser engraving. Plus, passivation and polishing are common on stainless pins and connectors where surface finish affects sealing and rust protection. Also, all finish work is done in-house under our quality system.
Frequently Asked Questions About Swiss Machining
What is the maximum bar size EGM can run on Swiss?
EGM’s Tsugami B0386-III handles bar up to 38 mm with guide bushing and 42 mm in chucker mode. Plus, our Tsugami B0205-V handles bar up to 20 mm. Therefore, small pins, connectors, threaded fasteners, and precision shafts across two size ranges all fit within our Swiss envelope for aerospace and defense buyers.
What CNC controls do EGM’s Swiss lathes run?
Both Tsugami platforms run FANUC controls. Specifically, the B0386-III features the FANUC 32i-B and the B0205-V features the FANUC 0i-TF Plus. Plus, both controls support Linear/circular interpolation, dwell functions, and English display language. Therefore, buyers get proven FANUC reliability across every Swiss job placed with EGM.
Can EGM machine long slender parts on Swiss?
Yes. The guide bushing supports the barstock right next to the cutting tool, so deflection stays low even on parts with high length-to-diameter ratios. Plus, the B0386-III cuts up to 320 mm with guide bushing, and the B0205-V cuts up to 210 mm with a stationary guide bushing. Therefore, long slender parts machine cleanly.
Does EGM handle ITAR-controlled Swiss jobs?
Yes. EGM Manufacturing is ITAR registered and holds a JCP Certification (DD2345). As a result, we can receive and handle controlled unclassified information and defense-related technical data. Plus, all ITAR drawings run through secure systems with access limited to cleared staff. Please contact our team before sending any controlled package.
What features can EGM cut in one Swiss setup?
Our Swiss cells handle turning, threading, grooving, drilling, tapping, milled flats, cross-holes, and back-work off the sub-spindle in one setup. Plus, the B0386-III supports thread whirling, polygon machining, and angled milling as available options. Therefore, buyers get complete parts off the machine ready for finishing or shipment.
