CNC Turning Parts

As a leading CNC machining factory, we specialize in delivering high-quality CNC turning parts designed for industries such as aerospace, automotive, medical devices, and industrial machinery. Below, we outline our comprehensive solutions, covering production processes, material options, design guidelines, and the unique advantages of our CNC turning capabilities.

Production Process of CNC Turning Parts

1. Design & Programming

  • Analyze CAD models to ensure compatibility with turning processes, focusing on axial symmetry and feature accessibility.
  • Generate optimized G-code using CAM software, factoring in spindle speed, feed rates, and tool paths to minimize cycle times.

2. Workpiece Setup

  • Secure the workpiece in a precision chuck or collet, ensuring concentricity and stability during high-speed rotation.
  • Select carbide or high-speed steel tools based on material hardness and feature complexity.

3. Multi-Axis Machining

  • Utilize 2- to 4-axis CNC lathes for operations like facing, taper turning, threading, and grooving.
  • Integrate live tooling for off-axis milling features (e.g., flats, slots) on materials like aluminum and brass.

4. Quality Assurance

Conduct in-process inspections using laser measuring systems and post-machining checks with CMM (Coordinate Measuring Machine) for ±0.01mm tolerance compliance.

Material Selection for CNC Turning Parts

Our turning services accommodate a wide range of materials, including:
  • Metals: Aluminum (6061/7075), Stainless Steel (304/316), Titanium (Ti-6Al-4V), Brass, Copper.
  • Plastics: Acrylic, PEEK, Nylon, Delrin (POM).

1. Material Advantages:

  • Titanium: Exceptional strength-to-weight ratio for aerospace and medical applications.
  • Brass: Excellent machinability and corrosion resistance for intricate components.
  • PEEK: High-temperature stability and biocompatibility for medical devices.

Surface Finishing Options:

  • Anodizing (Aluminum): Available in clear, black, or colored finishes for corrosion resistance.
  • Chromate Plating (Steel/Brass): Enhances conductivity and paint adhesion.
  • Bead Blasting: Smooths surfaces and deburrs edges for improved aesthetics.

Design Guidelines for CNC Turning Parts

Optimize your part design for manufacturability and cost efficiency:
  • Tolerances: Maintain ±0.01mm for standard parts; avoid overly tight tolerances (<±0.005mm) unless critical.
  • Geometry:
    • Use radii ≥0.2mm on internal corners to reduce tool wear.
    • Limit wall thickness to ≥0.5mm (metals) or ≥1mm (plastics) to prevent deformation.
  • Features:
    • Support on-axis/axial holes ≥1mm and radial holes ≥2mm (1mm for aluminum/brass).
    • Avoid ID grooves; prioritize OD grooves with ≥1.2mm width (0.5mm for aluminum/brass).
  • Threads: Specify UNC/UNF (from #2 to 0.5″) or metric threads (M2–M12); external threads preferred.

Advantages of CNC Turning

  1. High Precision: Achieve surface finishes as fine as Ra0.4μm for rotational symmetry.
  2. Material Efficiency: Minimize waste through optimized tool paths.
  3. Complex Feature Integration: Add grooves, threads, and off-axis holes in a single setup.
  4. Scalability: Ideal for both prototypes and high-volume production with consistent quality.

Disadvantages to Consider

  • Shape Limitations: Best suited for axially symmetric parts; complex geometries may require milling.
  • Material Restrictions: Harder materials like Inconel demand specialized tooling and slower processing.
  • Initial Investment: Higher setup costs for low-volume orders due to tooling requirements.

Applications of CNC Turning Parts

  1. Aerospace: Turbine shafts, bearing housings, and fasteners.
  2. Automotive: CV joints, piston rods, and transmission gears.
  3. Medical: Orthopedic implants, dental prosthetics, and surgical instruments.
  4. Industrial: Hydraulic cylinders, threaded rods, and precision bearings.
