CNC Turning for Plastic Components

High-precision CNC machining services for plastic rods, tubes, and bushings

CNC Plastic Turning

Plastic CNC turning is a precision plastic machining process that uses a CNC lathe to shape plastic materials into custom components. 

Excelite specializes in Plastic CNC Turning for high-precision, custom plastic parts. It is commonly used in aerospace, automotive, and industrial applications to produce components such as screws, bolts, nuts, bushings, and custom fittings. We provide machining solutions for materials like polycarbonate, acrylic, POM, and PTFE — from prototypes to large-volume production, tailored to your exact specifications.

CNC turning can be performed in various forms, including

  • Straight or cylindrical turning, which is ideal for large cuts
  • Taper CNC turning, which is suitable for creating parts with cone-like shapes.
  • Grooving
  • Threading
  • Knurling
  • Boring
  • Drilling

Our capabilities

  • Plastic CNC Turning Services
  • Turning Diameter Capacity: 10mm to 500mm 

  • Turning Length Capacity: up to 1,000mm 

  • Tolerance Range: ±0.1mm to ±0.05mm (plastic material)

Advantages of CNC Turning Plastic

  • Precision CNC turning, high precision and tight tolerances
  • Cost-Effectiveness: CNC turning compared to some other methods like injection molding, it tends to be more cost-effective for small to medium runs
  • Flexibility in Design, complex shapes and round, cylindrical, and symmetrical geometries parts
  • Enables high-speed rotation and material removal along X and Z axes

  • Capable of producing precise grooves, notches, and threads

  • Custom Plastic Components: CNC turning offers the flexibility to custom plastic parts based on specific design requirements.
