Precision CNC Turning Parts for Industrial Machinery

Product Overview

Our CNC turning process produces cylindrical and complex-shaped parts with micron-level precision, supporting industries such as aerospace, automotive, and energy. With ISO 9001:2015 and CE certification, these parts meet global quality standards for critical applications in harsh industrial environments (temperatures from -40°C to 200°C, vibration up to 100 Hz) .

Material

We offer a comprehensive material selection to match diverse industrial requirements:

• Stainless Steel (304, 316): For corrosion-resistant components (e.g., hydraulic valves, food processing equipment) with tensile strength 515-690 MPa, excellent machinability (machining rating 70% vs. 1018 steel), and resistance to chemical exposure (acids, alkalis)

• Carbon Steel (1045, 4140): Heat-treatable to 30-45 HRC for high-strength shafts and fasteners, with 4140 offering superior hardenability (up to 50mm diameter) for heavy-load applications

• Aluminum Alloy (6061-T6): Lightweight option (density 2.7 g/cm³) with tensile strength 310 MPa for robotics and automation parts, providing 60% weight reduction vs. steel with comparable stiffness

• Titanium (Grade 5): For high-temperature applications (up to 300°C) requiring strength-to-weight ratio superiority (specific strength 260 MPa·cm³/g), ideal for aerospace and high-performance machinery

• Engineering Plastics (Acetal, PEEK): Insulating, low-friction parts (coefficient of friction 0.15) for food processing or electrical machinery, with PEEK offering heat resistance up to 260°C

Features

Ultra-Precision Tolerances

Our Swiss-type CNC lathes (Star SR-32J, Citizen M32) achieve ±0.002 mm dimensional tolerance and 0.001 mm roundness, ensuring proper fit in precision assemblies like ball screw nuts (clearance <0.01mm) and bearing housings. Surface finishes as low as Ra 0.4 μm (achieved via superfinishing) reduce friction and improve sealing in hydraulic components, extending seal life by 30% . In-process probing systems (Renishaw OMP40-2) verify dimensions during machining, reducing scrap rates to <0.5%.

Repeatability

Temperature-controlled production environments (±2°C) and automated CMM (Coordinate Measuring Machine) inspection ensure part-to-part consistency within ±0.003 mm across production runs, critical for modular machinery assembly where interchangeability is required. Statistical Process Control (SPC) with Cpk ≥1.33 guarantees stable production, with real-time data monitoring for key dimensions .

Versatile Geometry Capability

The CNC turning process handles complex features including:

• Multi-start threads (up to 4 starts) with class 3A/3B fit (thread tolerance ensuring leak-free sealing in hydraulic connections)

• Tapered surfaces (0.5°-15°) with ±0.01° angular tolerance, critical for cone clutch assemblies and bearing seats

• Cross-drilled holes (diameter ≥1mm) with ±0.02 mm positional accuracy, enabling precise fluid flow in hydraulic manifolds

Custom Service

Our flexible manufacturing system supports industrial machinery OEMs with:

• Design assistance: Feasibility studies for complex geometries (e.g., internal threads, undercuts) and material selection guidance based on load, temperature, and corrosion requirements, with DFM reports provided within 3 business days

• Production flexibility: Batch sizes from 10 to 10,000+ units with economic order quantities (EOQ) optimization, reducing inventory costs by 20% through demand forecasting integration
