Swiss Machining in Fond du Lac, Wisconsin

Fond du Lac's Swiss machining shops operate modern CNC Swiss-type lathes ranging from 8mm to 32mm bar stock capacity. Common machines include Tornos DT26, Citizen A32, Tsugami Swiss-type machines, and Nomura multi-spindle models. Most shops have upgraded to live-tooling configurations, enabling integrated milling, drilling, and tapping operations without secondary handling. Spindle speeds exceed 10,000 RPM, with sub-micron positioning accuracy through ballscrew systems and closed-loop feedback. Automatic tool changers and gang tooling configurations allow for rapid setup transitions between jobs, reducing non-cutting time and improving throughput on short runs. Many Fond du Lac shops have invested in vision systems and in-process gauging—critical for medical and automotive applications where statistical process control (SPC) and Cpk documentation are mandatory. CAM software integration (NX, Mastercam, Fusion 360) enables rapid program generation from CAD files, accelerating time-to-production. Deburring and surface finishing are increasingly integrated in-house. Centrifugal deburring, electropolishing for medical-grade components, and centerless grinding for OD finishing allow shops to deliver ready-to-assemble parts. This vertical integration reduces lead times and minimizes quality variability associated with outsourced finishing.

Most active Swiss machining shops in Fond du Lac maintain ISO 9001:2015 certification and document traceability through material certs (3.1 test reports), first-article inspection (FAI), and ongoing SPC. Medical device shops pursue ISO 13485 certification, requiring validated cleaning processes, statistical design of experiments (DOE), and design failure mode effects analysis (DFMEA). Several shops maintain FDA DMF listings and support ISO 13485-certified device manufacturers through cleanroom protocols and gowning procedures. AS9100 Rev D certification is less common but available through specialized aerospace-focused shops in the region. ITAR compliance is maintained by shops serving defense contractors, with controlled access to tooling, part storage, and digital drawings. RoHS 2 and REACH compliance documentation is standard for automotive and electronics suppliers. Lead times for first-article inspection typically range from 5–10 business days, with documented inspection reports including SPC charts, tool-wear analysis, and material traceability. Most shops participate in third-party audits annually and maintain quality metrics publicly (on-time delivery, defect rates, first-pass yield). This transparency builds trust with OEMs and contract manufacturers who rely on repeatable, auditable processes for regulated industries.

Fond du Lac Swiss machining shops routinely machine stainless steel (304, 316L, 17-4PH), titanium alloys (Ti-6Al-4V), aluminum (2024, 7075), brass, bronze, and hardened tool steel (up to 62 HRC with carbide tooling). Medical-grade applications demand 316L or titanium for biocompatibility; aerospace applications require 17-4PH or Ti-6Al-4V with full material traceability. Most shops maintain relationships with specialty distributors (Ryerson, Metallic Building Company, Anixter) ensuring access to certified material blanks and mill certs. Part complexity ranges from simple turned pins (O.D. control only) to multi-feature assemblies with 30+ controlled dimensions. Swiss machines excel at eliminating secondary operations: a single-spindle Tornos can perform turning, threading, cross-drilling, live-tool milling, and part-off in a single setup. This capability is especially valuable for medical components where secondary handling introduces contamination risk and increases cost. Thread pitches down to 0.5mm and internal features (blind holes, pockets) are achievable through live-tool configurations. Minimum wall thicknesses of 0.020" (0.5mm) and corner radii of 0.010" (0.25mm) are routinely maintained. Concentricity and runout tolerances of 0.0005" TIR are standard for medical and precision bearing components. Surface finishes range from 63 Ra (as-machined stainless) to 16 Ra (polished for biocompatible surfaces) depending on application and finishing processes.

ManufacturingBase connects you directly with verified Swiss machining capabilities in Fond du Lac. Our platform allows you to filter by certification (ISO 13485, AS9100, ITAR), material capability, and equipment specifications. Upload your technical drawing, and qualified shops in the Fond du Lac area will respond with lead times, tooling quotes, and process capability data. You can review shop certifications, inspect machine inventory, and compare pricing across multiple providers without cold-calling or attending trade shows. When evaluating Fond du Lac shops, request machine specifications (model, spindle speed, live-tool configuration), quality documentation (ISO certs, NADCAP audit reports if applicable), and references from OEMs in your industry. Ask about setup times for your specific part geometry and whether the shop charges NRE for programming or tooling. Many shops offer CAD-to-quote turnaround within 48 hours, allowing you to evaluate feasibility before committing to engineering resources.
