Product Description

1. What types of plastics can be CNC machined?

We machine a wide range of engineering and commodity plastics, including:

• ABS (good toughness, moderate cost)

• Polycarbonate (PC) (high impact resistance, transparent options)

• Acrylic (PMMA) (optical clarity, UV resistance)

• POM (Delrin) (low friction, high stiffness)

• Nylon (PA6, PA66) (wear-resistant, flexible)

• PEEK (high-temperature, chemical-resistant)

• PTFE (Teflon) (non-stick, chemical inertness)

• HDPE & UHMW (low-cost, durable)
  

2. What tolerances can be achieved with CNC plastic machining?

• Standard tolerance: ±0.1 mm (±0.004")

• High precision: ±0.05 mm (±0.002") or better (depends on material and part geometry)
  
  3. How thin can CNC-machined plastic walls be?

• Minimum recommended wall thickness: 1.0 mm (0.04")

• For rigid plastics (e.g., PEEK, PC): Can go down to 0.5 mm with careful machining.
  

4. What surface finishes are available?

• As-machined (light tool marks)

• Sanded (smooth, Ra 1.6-3.2 μm)

• Polished (glossy/mirror finish)

• Bead blasted (matte texture)

• Painting/coating (custom colors, textures)
  

6. Does CNC machining cause stress or warping in plastic parts?

• Plastics are softer than metals, so improper machining can cause heat buildup, leading to warping or melting.

• We use sharp tools, optimized feeds/speeds, and air cooling to minimize stress.

• Annealing (heat treatment) can be applied for critical parts to relieve internal stresses.
  

7. Can you machine threaded holes in plastic?

Yes! We can machine:

• Standard threads (M3, M4, UNC, etc.)

• Self-tapping threads (for screws)

• Helical inserts (for reinforced threads in soft plastics)
  

8. What file formats do you accept for CNC machining?

Preferred formats:

• STEP (.stp) (best for 3D models)

• IGES (.igs)

• Parasolid (.x_t)

• DWG/DXF (for 2D drawings)

• STL (for prototyping, less precise)
  

9. How long does CNC plastic machining take?

• Prototype lead time: 7-10 days

• Production runs: 10-15 days (depending on quantity and complexity)

• Rush service: Available (contact for expedited options)
  

10. Why choose CNC machining over 3D printing for plastic parts?

11. Do you provide post-processing services?

Yes! We offer:

• Deburring & smoothing

• Painting & dyeing

• Laser engraving/text

• Assembly

• Quality inspection (CMM, micrometers)
  

12. How do I request a quote?

Submit your 3D model (STEP/IGES) + 2D drawings (PDF/DWG) with:

• Material preference

• Quantity

• Tolerances & surface finish requirements

• Any special notes (threads, inserts, etc.)
