Understanding CNC Turning Service

CNC turning is a manufacturing process where bars of material are held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape. In CNC turning, the cutter can be fed into the rotating workpiece at various angles and many tool shapes can be used.

Key Features of CNC Turning:

  • Precision and Complexity: CNC turning is renowned for its precision and capability to produce complex parts. The computer-controlled process allows for exact dimensions and complex geometries.
  • Material Versatility: This process is compatible with a wide range of materials, including metals like aluminum and steel, and plastics such as PP and ABS. This versatility makes it ideal for various industries and applications.
  • Efficiency: CNC turning is an automated process, meaning it can produce parts quickly and consistently, making it suitable for both prototype development and large-scale production.
  • Customization: It offers high levels of customization. Parts can be tailored to specific dimensions and shapes as per the requirements, providing flexibility in design and production.

Precision in Every Dimension

CNC Turning Tolerances & Standards

  • Dimensional Tolerances for Size and Position

    Applicable Features: Includes length, width, height, and diameter dimensions, along with positional aspects like concentricity and symmetry. Standard Tolerance: ±0.005 inches for both dimensional accuracy and positional precision.

  • Tolerances for Orientation and Form

    Lengths up to 12 Inches: Tolerance of ±0.005 inches, with an angular deviation allowance of 1/2 degree. Lengths exceeding 24 Inches: For these dimensions, refer to the Xometry Manufacturing Standards for specific tolerances.

  • Edge Conditioning Standards

    Default Treatment: Sharp edges will be systematically deburred and softened. Special Requirements: If certain edges need to remain sharp for critical applications, this requirement should be explicitly indicated on the technical drawings or specifications.
