High-Precision Machining for Strong, Impact-Resistant & Transparent PC Parts
Custom Prototypes and Production with Excellent Dimensional Accuracy

What is PC CNC Machining?

Polycarbonate (PC) is a tough, transparent engineering plastic with high impact strength and good heat resistance. It machines cleanly with sharp tools and proper heat control, making it ideal for optical guards, covers, and structural components.

  • Tooling: Sharp polished carbide / O-flute; high rake to shear and avoid stress whitening.
  • Heat control: Air blast or light mist. Avoid melting—chips should curl, not smear.
  • Feeds/Speeds: Moderate SFM, steady chip load; use a light finish pass for optics-facing edges.
  • Workholding: Soft jaws/vacuum; minimize deflection on thin covers and large panels.

Key Considerations

For clear edges and optics surfaces, climb mill with sharp tools, reduce step-over, and plan a final “polish” pass. Flame/polish or vapor finishing can be used when specified.

PC is notch-sensitive—avoid sharp internal corners and heavy deburr pressure. Manage residual stress on large, thin parts: rough → rest/condition → finish.

Precision PC CNC Machining

PC 3/4/5-axis CNC milling for clear covers and structural panels

3, 4, 5-Axis CNC Milling

High-clarity contours, pockets, and windows for covers, shields, and housings. Balanced holders, sharp cutters, and air blast deliver uniform textures and minimal stress whitening.

PC CNC turning for lenses, rings, and cylindrical guards

CNC Turning & Mill-Turn

Smooth OD/ID finishes for rings, view-ports, and cylindrical guards. Positive-rake inserts and steady feed reduce chatter and haze; add a light finishing pass on show surfaces.

Machinable PC Grades

Pick the right balance of clarity, rigidity, heat, and ESD/UV performance.

Optical clear PC window and cover (3:2)

Optical / Clear PC

  • High clarity & impact strength
  • Good heat resistance
  • Guards, view-ports, lenses
  • Polish/finish options available

Use sharp tools, fine step-over, and a light finish pass. Consider flame/vapor/abrasive polish when specified.

Glass-filled PC structural bracket (3:2)

Glass-Filled PC

  • Higher stiffness & heat deflection
  • More abrasive—use coated carbide
  • Structural housings & brackets
  • Dimensional stability improved

Lower SFM, steady feed; consider wear-resistant coatings and frequent tool checks to maintain finish.

UV-stabilized PC outdoor panel (3:2)

UV-Stabilized PC

  • Outdoor clarity retention
  • Signage, covers, enclosures
  • Machines like clear PC
  • Check color/coat requirements

Parameters similar to clear PC; verify coating/film removal and edge finishing preferences.

ESD-safe polycarbonate tooling tray (3:2)

ESD / Antistatic PC

  • Static-safe handling & covers
  • Fillers change chip behavior
  • Trays, nests, windows
  • Surface resistivity to spec

Tune feeds for sharp edges and clarity; confirm resistivity targets and handling/cleaning procedures.
