Why Choose JST's Aluminum CNC Turning Parts
Superior Heat Dissipation and Lightweight Design in CNC Turned Aluminum Parts
JST Industry focuses on maximizing the inherent advantages of aluminum to deliver superior CNC turning aluminum parts for high-tech applications:
Exceptional Thermal Management
Aluminum’s high thermal conductivity (especially 6061) makes it perfect for dissipating heat rapidly. We produce specialized motor cooling fins and heat sinks that are highly efficient, directly extending the lifespan of the motor components.
Ultra-Lightweight Solutions
We prioritize weight reduction without compromising strength. Utilizing alloys like 7075, we create structurally robust aluminum CNC turning parts essential for applications like robotics, drones, and high-speed moving assemblies where mass minimization is critical.
Aesthetic and Protective Anodizing
Our components undergo professional anodizing (Type II for color/aesthetics; Type III for wear resistance). This process enhances the inherent corrosion resistance of the aluminum CNC turned parts and provides a durable, customizable finish.
High-Speed, Cost-Effective Machining
Aluminum's excellent machinability allows for faster cutting speeds and reduced cycle times compared to steel. This efficiency translates directly into lower manufacturing costs and quicker delivery of high-volume orders.
Résistance à la corrosion
Naturally resistant to rust and atmospheric corrosion, these aluminum CNC turning parts maintain integrity in environments exposed to moisture, making them ideal for outdoor or marine applications.

FAQ
Q1: What are the best aluminum alloys for complex CNC turning aluminum parts?
A: For general precision and strength, 6061 is the standard choice due to its excellent machinability and low cost. For extremely high-stress applications (like high-performance motor shafts or aerospace brackets), 7075 is preferred due to its superior strength, comparable to many steels.
Q2: Why is anodizing recommended for aluminum CNC turned parts?
A: Anodizing creates a hard, corrosion-resistant oxide layer on the surface. This is vital for protecting aluminum CNC turned parts from wear and atmospheric corrosion, especially important if the components are exposed to the environment or friction (e.g., Type III Hard Coat Anodizing).
Q3: Can you ensure the concentricity required for a motor shaft or critical CNC turned aluminum parts?
A: Absolutely. Concentricity is critical for rotating components. We use advanced CNC lathes and rigorous in-process inspection (using high-precision chucks and collets) to ensure runout and concentricity tolerances meet or exceed the requirements for critical motor shafts and bearing housings.
Q4: Are aluminum CNC turning parts suitable for high-vibration environments?
A: Yes. While lighter than steel, certain aluminum alloys (like 7075) offer excellent fatigue properties. Furthermore, aluminum’s dampening characteristics can sometimes be advantageous in reducing resonance, making it an ideal material for many high-frequency or high-vibration applications.
Q5: What file formats do you require for a quote on a custom aluminum CNC turning part?
A: We require 3D files (STEP, IGES preferred) and a 2D engineering drawing. The drawing must clearly specify all critical dimensions, tolerances, required aluminum alloy (e.g., 6061-T6), and any necessary post-processing such as anodizing or Alodine chemical film.
