Technical Capabilities

Swiss Milling Machine – Technical Specifications

Swiss-type milling machines, often referred to as Swiss CNC lathes or Swiss screw machines, are precision machine tools optimized for high-accuracy machining of small, complex components. While traditionally known for turning operations, modern Swiss machines integrate multi-axis milling and turning capabilities, enabling complete part fabrication in a single setup. Below are the key technical specifications focused on 3/4/5-axis milling and turning, tight tolerance performance, and compatibility with common engineering materials.

Feature	Specification
Machine Type	CNC Swiss-type Automatic Lathe with Multi-Axis Milling and Turning
Primary Axes Configuration	3-Axis (X, Z, C), 4-Axis (adds B or Y), 5-Axis (X, Z, C, Y, B)
Milling Axes	Y-axis ± cross slide; B-axis (rotary milling spindle) for off-center and angled features
Turning Capability	Main spindle turning with guide bushing for improved rigidity and accuracy
Sub-Spindle	Yes, for backworking operations (part transfer and secondary machining)
Bar Capacity	Typically 1 mm to 38 mm diameter (depending on model)
Maximum Spindle Speed	10,000 – 18,000 RPM (main and sub-spindle)
Milling Spindle Speed	Up to 20,000 RPM (high-speed motorized live tooling)
Positioning Accuracy	±0.001 mm (±0.00004 in)
Repeatability	±0.0005 mm (±0.00002 in)
Tight Tolerance Capability	±0.002 mm to ±0.005 mm typical for critical dimensions
Control System	Fanuc, Siemens, or Mitsubishi CNC with multi-channel synchronization
Live Tooling	Radial and axial tooling stations for milling, drilling, tapping, and contouring
Coolant System	High-pressure through-tool coolant (up to 70 bar) for chip control and tool life
Materials Compatible	Aluminum (6061, 7075), Steel (1018, 4140, 17-4 PH), Stainless Steel (303, 316), ABS, Nylon (PA6, PA66), PEEK, PTFE
Typical Applications	Medical components, aerospace fittings, precision connectors, shafts, bushings, and complex micro-machined parts
Surface Finish	Ra 0.4 µm to 0.8 µm achievable (as-machined), finer with polishing
Automation Ready	Yes – compatible with bar feeders, gantry loaders, and robotic integration

Notes on Material Machinability:
Aluminum: Excellent machinability; high speeds and feeds possible, minimal tool wear.
Steel and Stainless Steel: Moderate to challenging; requires rigid setup and appropriate tooling (carbide or coated inserts).
ABS and Nylon: Thermoplastics require sharp tooling, lower cutting forces, and effective chip removal to avoid melting or deformation.

Swiss milling machines deliver exceptional precision for high-mix, low-to-medium volume production, particularly in industries requiring tight tolerances and repeatable accuracy such as medical, aerospace, and optoelectronics.

From CAD to Part: The Process

Honyo Prototype Swiss Milling Process Overview

Honyo Prototype utilizes a streamlined, technology-driven workflow for Swiss screw machine production, ensuring precision, efficiency, and rapid turnaround for complex turned components. The process integrates advanced automation with expert engineering oversight at critical stages.

CAD Upload
Customers initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid, or native SolidWorks/CREO formats) via Honyo’s secure customer portal. Our system validates file integrity and geometry completeness upon submission, flagging common issues like missing tolerances or non-manufacturable features before proceeding. This stage establishes the digital foundation for all subsequent steps, with automated version control to prevent miscommunication.

AI-Powered Quoting
Uploaded CAD data feeds directly into Honyo’s proprietary AI quoting engine, which analyzes geometric complexity, material requirements, tolerances, and surface finish specifications. The system cross-references real-time data from our machine shop—including current capacity, material costs, and tooling availability—to generate an accurate, itemized quote within 2 business hours. Critical factors like bar stock utilization efficiency, secondary operation needs, and Swiss-specific constraints (e.g., guide bushing compatibility, sub-spindle synchronization) are algorithmically evaluated. A Senior Manufacturing Engineer reviews all AI-generated quotes to verify feasibility and address edge cases, ensuring pricing reflects actual production physics.

DFM Analysis and Collaboration
Following quote acceptance, Honyo’s DFM (Design for Manufacturability) team conducts a rigorous technical review. For Swiss machining, this focuses on optimizing bar-fed processes: validating minimum wall thicknesses relative to guide bushing stability, assessing tool clearance for live tooling operations, and identifying opportunities to consolidate features using the main and sub-spindles. The DFM report—delivered within 24 hours—details actionable recommendations such as tolerance relaxation, feature repositioning to minimize setups, or material substitution for improved chip control. Customers receive direct access to our engineering team for collaborative refinement, reducing prototype iterations and accelerating time-to-part.

Precision Production
Approved designs move to our Swiss turning cell, featuring multi-axis Tsugami and Citizen machines with live tooling, Y-axis capability, and sub-spindles for complete part-off. Production adheres to strict protocols:
Raw material (e.g., 303SS, 6061-T6, PEEK) is inspected per ASTM/AMS standards prior to loading
First-article inspection (FAI) per AS9102 is performed before batch runs, including CMM verification of critical Swiss-specific dimensions (e.g., concentricity between main/sub-spindle operations)
In-process SPC monitoring tracks key parameters like tool wear and vibration to maintain ±0.0002″ tolerances
Secondary operations (e.g., grinding, threading, plating) are coordinated through Honyo’s vetted partner network under unified quality oversight

Typical lead times balance speed with Swiss machining complexity:

Part Complexity	Typical Lead Time	Key Drivers
Low (≤5 features, standard tolerances)	5–7 business days	Single-setup optimization, high bar stock utilization
Medium (8–12 features, tight tolerances)	8–12 business days	Sub-spindle synchronization, live tooling coordination
High (15+ features, micro-features, exotic materials)	12–18 business days	Multi-operation sequencing, in-process metrology validation

Quality-Controlled Delivery
All parts undergo final inspection against the customer’s print, with full FAI documentation (including CMM reports and material certs) packaged with the shipment. Honyo coordinates global logistics via DHL/FedEx with real-time tracking, and provides digital delivery confirmation including batch-specific process data. For mission-critical applications, we offer optional vacuum-sealed packaging with humidity indicators and ITAR-compliant shipping documentation. Post-delivery, our engineering team conducts a lessons-learned review to refine future Swiss machining processes for the customer’s specific part family.

This integrated workflow—combining AI efficiency with deep Swiss machining expertise—ensures Honyo consistently delivers complex precision components with 99.2% on-time delivery and first-pass yield rates exceeding 95% across our customer base.
