Technical Capabilities
CNC screw machines are precision manufacturing systems designed for high-volume production of small to medium-sized turned and milled components. While traditionally used for simple bar-fed turning operations, modern CNC screw machines have evolved to incorporate multi-axis milling, turning, and advanced control systems to achieve tight tolerances and complex geometries. These machines are commonly used in industries such as aerospace, medical, and automotive where precision and repeatability are critical.
The following table outlines the key technical specifications relevant to CNC screw machines with capabilities in 3/4/5-axis milling, turning, and tight-tolerance machining across common engineering materials.
| Specification | Detail |
|---|---|
| Machining Axes | Modern CNC screw machines support up to 5-axis simultaneous machining (X, Y, Z linear axes + A and B rotary axes), enabling complex contouring and multi-sided operations without manual re-fixturing. Some models integrate sub-spindles and live tooling for combined turning and milling. |
| Spindle Speed | Up to 12,000 RPM (standard); high-speed models reach 20,000+ RPM for fine finishing and small-tool applications in aluminum and plastics. |
| Bar Capacity | Typically 1/2″ to 2″ (12–50 mm) diameter bar stock, depending on machine size and model. Larger models support extended bar feeding for continuous operation. |
| Positioning Accuracy | ±0.0001″ (±2.5 µm) with high-resolution encoders and thermal compensation systems. |
| Repeatability | ±0.00005″ (±1.3 µm) under stable environmental conditions, essential for tight-tolerance production. |
| Tolerance Range | Capable of holding tolerances as tight as ±0.0002″ (±5 µm) on critical dimensions, especially in diameter, concentricity, and feature location. |
| Feed Rate | Up to 1,500 inches per minute (ipm) on linear axes, supporting both high-speed roughing and fine finishing. |
| Control System | Fanuc, Siemens, or Mitsubishi CNC controls with advanced programming support (G-code, conversational, CAD/CAM integration). |
| Tooling Capacity | 8–24 station tool turrets with optional live tooling for cross-drilling, tapping, and milling operations. |
| Materials Processed | Optimized for aluminum (6061, 7075), steel (1018, 4140, stainless 303/316), engineering plastics (ABS, Nylon 6/66), and brass. Each material requires specific tooling and cutting parameters. |
| Aluminum Machining | High-speed cutting with carbide tools; excellent surface finish and chip evacuation. Typical tolerance: ±0.0002″. |
| Steel Machining | Lower spindle speeds and higher torque; suitable for hardened and stainless steels. Tight tolerances maintained with rigid tooling and coolant-through spindles. |
| ABS & Nylon Machining | Low cutting forces and optimized feed rates to prevent melting or deformation. Coolant or air blast used instead of liquid coolant. Dimensional stability monitored due to material hygroscopy. |
| Coolant System | Through-spindle coolant (up to 1,000 psi) for chip control and tool life; optional mist or air cooling for plastics. |
| Automation Compatibility | Designed for integration with bar feeders, gantry loaders, and robotic part handling for lights-out manufacturing. |
These specifications reflect the advanced capabilities of modern CNC screw machines in producing high-precision, complex components from a wide range of materials while maintaining tight dimensional control and surface quality.
From CAD to Part: The Process
Honyo Prototype CNC Screw Machine Process Overview
Honyo Prototype utilizes a streamlined, technology-driven workflow for CNC screw machine (Swiss-type lathe) production, designed to accelerate prototyping and low-volume manufacturing while ensuring precision and cost efficiency. Our process eliminates traditional bottlenecks through integrated digital tools and engineering expertise.
Upload CAD
Clients initiate the process by uploading 3D CAD models (STEP, IGES, or native formats) via our secure customer portal. The system validates file integrity and geometric complexity, automatically categorizing the part for Swiss-type machining suitability. This step includes metadata capture for material specifications, tolerances, and surface finish requirements, ensuring all critical parameters are preserved for downstream processing.
AI-Powered Quoting
Uploaded CAD data feeds into Honyo’s proprietary AI quoting engine, which analyzes geometric complexity, feature density, and dimensional tolerances against our Swiss machine capabilities. The system cross-references real-time material costs, machine availability, and labor rates to generate a detailed quote within 2 business hours. Quotes include machine time estimates, material utilization metrics, and a preliminary risk assessment for challenging features. Clients receive transparent cost breakdowns with options for material substitutions or tolerance adjustments to optimize value.
Engineering-Validated DFM
Following quote acceptance, Honyo’s manufacturing engineers perform a rigorous Design for Manufacturability (DFM) review. While the AI system flags initial concerns (e.g., non-standard thread pitches, thin-wall instability, or undercut limitations), our engineers apply domain-specific knowledge to refine the process. Key DFM actions include:
Optimizing part orientation to minimize secondary operations
Recommending tolerance relaxations for non-critical features
Validating chip control strategies for exotic alloys
Simulating toolpath collisions using CAM software
A formal DFM report with actionable recommendations is shared within 24 hours, requiring client sign-off before production. This phase typically reduces lead times by 15–30% by resolving manufacturability issues upfront.
Precision Production
Approved designs move to our CNC Swiss screw machine fleet, featuring multi-axis Tsugami and Tornos platforms with live tooling and sub-spindles. Production adheres to the following protocol:
| Parameter | Specification | Control Method |
|---|---|---|
| Material | Stainless steel, brass, titanium, alloys | Certified mill certs + in-house PMI |
| Tolerances | ±0.0002″ (5µm) on critical features | In-process CMM verification |
| Surface Finish | Ra 0.8µm standard; Ra 0.4µm achievable | Profilometer validation |
| Lot Traceability | Full serial-numbered part tracking | Barcoded work orders |
Each run includes first-article inspection (FAI) per AS9102 standards, with real-time SPC monitoring of critical dimensions. Complex geometries leverage our Y-axis milling capabilities for integrated milling/drilling operations, eliminating secondary setups.
Guaranteed Delivery
Completed parts undergo final cleaning, deburring, and 100% functional inspection against client specifications. All deliverables include:
Dimensional inspection reports (PDF/Excel)
Material certification documentation
