With 15+ years of expertise in metal machining, we specialize in customized metal parts via 5-axis CNC services—focused on solving metal-specific challenges (hardness, thermal deformation, corrosion) while delivering tailored solutions. Unlike generic machining, our process is optimized for metal properties: from high-strength titanium (aerospace) to corrosion-resistant stainless steel (medical) and conductive brass (electronics). We work closely with customers to translate unique design requirements into precision metal parts that meet functional, durability, and industry standards.
Our 5-axis machines (DMG Mori NHX 5000, Haas UMC-750) are equipped to handle the unique properties of metals:
- High-Hardness Metals: For 4140 alloy steel (50–55 HRC) or titanium Grade 5, we use ultra-hard carbide tools (WC-Co with 10% Co content) and high-torque spindles (40 N·m) to avoid tool wear, ensuring consistent tolerance (±0.002mm) across batches.
- Thermal Deformation Control: For aluminum (prone to heat warping), we use high-pressure cooling (70 bar) and variable cutting speeds (1,500–3,000 RPM) to keep metal temperature ≤50℃—critical for thin-walled aluminum parts (0.5mm wall thickness) like electronic enclosures.
- Corrosion-Resistant Finishes: For 316L stainless steel medical parts, we add passivation (ASTM A967) or electropolishing to eliminate micro-pores, ensuring compliance with ISO 13485 and reducing bacterial adhesion.
We translate customer designs into complex metal components that 3-axis machining cannot achieve:
- Multi-Sided Complexity: Machines 0–360° angled holes, spherical surfaces, and asymmetric features in one setup. For example, a customer’s aerospace aluminum bracket (6061) with 45° mounting holes and a curved stress-relief groove is produced with ±0.003mm alignment, avoiding repositioning errors.
- Thin-Walled & Micro-Features: Creates thin-walled metal parts (minimum 0.3mm wall thickness) and micro-features (0.1mm-diameter holes in brass) for electronics—using adaptive cutting technology to prevent metal deformation.
We customize processes to meet industry standards for metal parts:
- Aerospace: Titanium Grade 5 parts with AS9100 compliance—machined to ±0.001mm tolerance, with ultrasonic testing (UT) to detect internal defects, ensuring durability under high pressure.
- Medical: 316L stainless steel surgical instruments—polished to Ra ≤0.02μm, with no sharp edges (≤0.01mm radius) to reduce tissue damage, complying with ISO 13485.
- Automotive: 4140 alloy steel transmission shafts—heat-treated to 50 HRC, with concentricity ≤0.001mm to avoid vibration, meeting IATF 16949 standards.
- Requirement Alignment: Collaborate with customers to define metal material (e.g., "316L for corrosion resistance"), part geometry (CAD/STEP files), tolerance, and industry standards (e.g., AS9100).
- Metal-Specific DFM: Provide 24-hour Design for Manufacturability analysis—e.g., adjusting a customer’s titanium part’s fillet from 0.1mm to 0.2mm to avoid tool breakage, or recommending 6061 over 7075 for cost savings if strength requirements allow.
- Prototype Production: Manufacture custom metal samples in 4–6 days, using the same material and process as bulk production. Provide CMM inspection reports to validate precision.
- Feedback Iteration: Refine the prototype based on customer feedback—e.g., tightening tolerance from ±0.005mm to ±0.003mm, or changing surface treatment from anodization to PVD.
- Bulk Production: Launch mass production with automated 5-axis cells, conducting 100% visual inspection and 20% dimensional sampling to ensure consistency.
- Precision Testing: Use Zeiss CMM (±0.0005mm accuracy) for dimensional checks, Rockwell hardness testers for metal hardness verification, and salt spray chambers for corrosion resistance testing.
- Material Traceability: Provide mill certificates for all metals (e.g., ASTM B265 for titanium, ASTM A240 for stainless steel) to ensure compliance with industry standards.
- Certifications: Complies with ISO 9001—ensuring customized metal parts meet global quality requirements.
