CNC Milling Parts

As a leading CNC machining factory, we specialize in delivering high-quality CNC milling parts tailored to meet the exacting demands of industries such as aerospace, automotive, medical, and industrial equipment. Below, we outline the production process，material selection, design guidelines, advantages, and applications of our CNC milling services.

Production Process of CNC Milling Parts

1. Design Analysis & Programming

  • Review CAD drawings to understand geometric requirements, material specifications, and tolerance limits.
  • Generate optimized G-code using CAM software, ensuring tool paths minimize material waste and machining time.

2. Machine Setup & Fixturing

  • Secure the workpiece on the milling table using clamps or vises, leveraging T-slots for stability.
  • Select appropriate cutting tools (e.g., end mills, face mills) based on material hardness and feature complexity.

3. Precision Machining

  • Utilize 3-axis or 5-axis CNC milling machines to execute programmed movements, removing material layer by layer.
  • Integrate coolant systems to reduce heat and extend tool life during high-speed operations.

4. Quality Control

  • Conduct in-process inspections using measuring tools (e.g., calipers, micrometers) to verify dimensions.
  • Perform final checks against CAD models to ensure compliance with tolerances (typically ±0.01mm).

Material Selection for CNC Milling Parts

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

Material Advantages

  • Aluminum: Lightweight, corrosion-resistant, ideal for prototyping and structural components.
  • Titanium: High strength-to-weight ratio, biocompatible, suitable for aerospace and medical applications.
  • PEEK: Heat-resistant, durable, widely used in high-performance engineering parts.

Design Guidelines for CNC Milling Parts

To optimize manufacturability and cost efficiency, consider the following:
  • Tolerances: Avoid overly tight tolerances (e.g., ±0.005mm) unless critical, as they increase production costs.
  • Geometry: Use rounded internal corners (radii ≥0.2mm) to reduce tool wear and stress concentration.
  • Thickness: Maintain minimum wall thickness of 1mm for plastics and 1.5mm for metals to prevent deformation.
  • Threading: Opt for external threads or insert threads for internal features to enhance durability.

Advantages of CNC Milling

  1. Precision & Repeatability: Achieve consistent results with tight tolerances, ensuring part interchangeability.
  2. Complex Geometry: Manufacture intricate shapes, deep cavities, and 3D surfaces using multi-axis machines.
  3. Rapid Prototyping: Accelerate time-to-market with quick turnaround for functional prototypes.
  4. Material Versatility: Work with both metals and plastics, including high-hardness alloys.

Disadvantages to Consider

  • Material Waste: Subtractive process may generate scrap, though optimized tool paths mitigate this.
  • Initial Costs: Investment in advanced CNC machines and tooling may be higher for low-volume orders.

Applications of CNC Milling Parts

  1. Aerospace: Turbine blades, brackets, and structural components.
  2. Automotive: Engine mounts, transmission housings, and custom jigs.
  3. Medical: Orthopedic implants, surgical instruments, and dental prosthetics.
  4. Industrial: Valves, gears, and precision fixtures for machinery.

Surface Finishing Options

Enhance aesthetics and functionality with post-machining treatments:
  • Anodizing (Aluminum): Available in colors like black, blue, or clear for corrosion resistance.
  • Polishing: Smooth surfaces for optical or hygienic applications.
  • PVD Coatings: Durable finishes (e.g., gold, black) for wear resistance.
