  • CNC Machining Applications by Product Category

    This section explains how CNC machining supports different product categories across EV, automotive, and motorcycle & racing applications.

    CNC machining is commonly used for EV components where precision, flexibility, and reliability are critical.

    Typical CNC-machined EV parts include:

    • Aluminum battery housings and covers
    • Cooling-related aluminum parts and interfaces
    • Power electronics enclosures and base structures
    • Structural components requiring tight tolerance and repeatability

    Why CNC for EV components:

    • Supports complex geometry and frequent design iterations
    • Enables precise control of flatness and sealing surfaces
    • Allows reliable inspection for safety-critical applications

    For automotive applications, CNC machining is widely used for functional and structural aluminum parts.

    Typical CNC-machined automotive parts include:

    • Brackets and mounting structures
    • Engine bay aluminum components
    • Transmission and chassis-related parts
    • Precision covers and functional housings

    Why CNC for automotive components:

    • Suitable for low to mid-volume production
    • Provides stable dimensional accuracy
    • Easily integrates with secondary operations and surface finishing

    In motorcycle and racing applications, CNC machining enables high-precision and performance-oriented parts.

    Typical CNC-machined motorcycle & racing parts include:

    • Billet fuel caps, coolant caps, and oil caps
    • Precision knobs, levers, and handles
    • Lightweight performance and decorative aluminum components

    Why CNC for motorcycle & racing components:

    • Excellent surface finish and aesthetic control
    • Ideal for billet aluminum parts and customization
    • Supports small batches and design flexibility

    When CNC Machining Makes Engineering Sense

    • Tight tolerance or critical fit is required
    • High flatness or sealing surfaces are involved
    • Geometry is not suitable for casting or extrusion
    • Prototyping or frequent design changes are expected

    CNC machining is often selected not for cost efficiency, but for reliability, inspectability, and engineering flexibility.
