Technical Capabilities
CNC Swiss screw machines are precision machining systems designed for high-accuracy production of small, complex turned parts. These machines combine turning with multi-axis milling capabilities (typically 3, 4, or 5-axis) to perform intricate operations in a single setup. The guide bushing design supports the workpiece close to the cutting tool, enabling tight tolerance machining, especially for slender components.
Key technical capabilities include simultaneous turning and milling, live tooling, sub-spindles for backworking, and high-speed spindles optimized for fine surface finishes. These systems are ideal for industries requiring precision components such as medical, aerospace, and electronics.
Common materials processed include aluminum and steel for structural and conductive parts, and engineering plastics like ABS and nylon for insulative or lightweight applications. Machine performance is optimized across these materials through adjustable spindle speeds, feed rates, and tooling strategies.

From CAD to Part: The Process
Honyo Prototype CNC Swiss Screw Machine Process Overview
Our end-to-end CNC Swiss screw machine process is engineered for precision, speed, and zero-defect delivery of high-complexity micro-machined components. This workflow integrates automation with expert engineering oversight to serve medical, aerospace, and industrial clients requiring tight tolerances (±0.0002″) and sub-micron surface finishes.
CAD Upload & Initial Processing
Clients upload native or neutral CAD files (STEP, IGES, Parasolid) via our secure portal, specifying material, finish, and critical tolerances. Our system validates geometry integrity and flags incomplete metadata before progression. Unlike generic platforms, we require explicit documentation of functional datums and secondary operation interfaces to prevent downstream DFM conflicts.
AI-Powered Quoting with Engineering Validation
Proprietary AI analyzes the CAD model against 12,000+ historical Swiss machining datasets to generate a preliminary quote within 90 minutes. However, this is not an automated decision. Senior manufacturing engineers review AI outputs for:
Feasibility of micro-features (e.g., <0.5mm diameters)
Material waste optimization via bar stock diameter simulation
Cycle time validation against machine kinematics
Only after engineer sign-off is the quote released, ensuring no “false economy” in pricing.
Engineering-Led DFM Analysis
This phase is where Honyo differentiates. Our Swiss specialists conduct a collaborative DFM review focusing on:
Geometry refinement: Suggesting chamfer adjustments or radius modifications to prevent chatter in deep grooves
Material strategy: Recommending alternatives like 303SS vs. 304SS for improved chip control without compromising specs
Fixture optimization: Proposing custom guide bushing setups for slender parts (L/D >10:1)
Tolerance realignment: Flagging unrealistic GD&T callouts that increase scrap risk
The client receives a marked-up CAD package with cost-saving alternatives, not just a checklist.
Precision Production Execution
Approved designs move to our Tornos Evolution 2 Swiss machines with 9+ axes and real-time in-process gaging. Key production protocols:
Material verification: Every bar lot undergoes PMI testing pre-load
First-article inspection: Full CMM report against all critical dimensions before batch run
Statistical process control: Subgroup sampling every 15 minutes with SPC charting
Chip management: Closed-loop coolant filtration to prevent recutting fines on medical threads
All processes adhere to ISO 13485 and AS9100 standards with full traceability from raw material to shipment.
Delivery & Quality Assurance
Final inspection includes surface roughness validation (per ISO 4287), thread profilometry, and optional helium leak testing. Clients receive:
Dimensional report with actual vs. nominal data
Material certification and RoHS compliance documentation
Real-time production analytics via client portal
Packaging certified for ESD-sensitive or sterile applications
Standard lead time is 7–10 days for 1–500 pieces, with expedited options for urgent medical device needs.
Material Optimization Reference
Common material substitutions identified during DFM to balance cost and machinability:
| Base Material Requested | Honyo-Recommended Alternative | Machinability Improvement | Typical Cost Impact |
|---|---|---|---|
| 17-4PH Stainless | Custom 416Se Stainless | 35% faster cycle time | -18% per part |
| Ti-6Al-4V | Beta-C Titanium alloy | 50% longer tool life | -22% per part |
| Inconel 718 | Custom HASTELLOY® variant | Reduced work hardening | -15% per part |
This closed-loop process ensures your Swiss-turned components meet functional requirements while minimizing total cost of ownership.
