Frequently Asked Questions
What types of plastics can be CNC machined?
We machine a wide range of engineering plastics, including ABS, Polycarbonate (PC), Acrylic (PMMA), POM (Delrin), Nylon (PA6/PA66), and high-performance PEEK.
What tolerances can be achieved with CNC plastic machining?
Our standard tolerance is ±0.1 mm, while high-precision requirements can reach ±0.05 mm or better, depending on the material and geometry.
What surface finishes are available?
Options include as-machined, sanded (Ra 1.6-3.2 μm), polished (mirror finish), bead blasted (matte), and custom painting or coating.
Does CNC machining cause stress or warping in plastic?
We use sharp tools and optimized speeds to minimize heat. For critical parts, annealing (heat treatment) can be applied to relieve internal stresses.
Why choose CNC machining over 3D printing?
CNC machining offers higher accuracy (±0.05 mm), superior material strength (fully dense), and smoother surface finishes compared to 3D printing.
What is the typical lead time for prototypes?
Standard prototype lead time is 7-10 days. Production runs typically take 10-15 days, with rush services available upon request.
