CNC Acrylic Machining Services — Precision-Cut Parts

CNC acrylic machining uses computer-controlled mills and lathes to cut, drill and finish acrylic sheet or rod into precise parts, holding tolerances and edge clarity that hand cutting or laser work alone can’t match.

Acrylic is brittle and heat-sensitive, so it needs sharp tooling, slow feeds and good chip evacuation to avoid melting, chipping or stress cracks. It’s routine work for a shop set up for plastics, but risky on general-purpose metal tooling.

XTJ CNC holds ±0.005 in (0.13 mm) as standard on acrylic parts, tighter on smaller turned features, using dedicated plastic-machining feeds and fixturing to avoid distortion.

Cast acrylic machines cleaner and has better optical clarity but costs more; extruded acrylic is cheaper and more consistent in thickness, but can show more tool marks. We’ll recommend the grade that fits your part and budget.

Simple acrylic parts typically run $30-$300 each depending on size and finish; complex optical parts with polishing cost more. Send your file for an exact quote.

Keep wall thickness even, avoid unnecessary tight tolerances on non-critical features, and specify sandblasting instead of polishing where optical clarity isn’t required — all three cut machining and finishing time.

Prototype acrylic parts typically ship in 3-5 days; production runs usually take 1-4 weeks depending on quantity, thickness and finishing.

Laser cutting is fast and cheap for flat, 2D shapes but leaves a slightly rough, sometimes discolored edge. CNC machining handles 3D contours, tighter tolerances and leaves a cleaner edge ready for polishing.

Yes. Flame polishing and diamond polishing both bring machined or laser-cut acrylic edges to a glass-clear finish, and vapor polishing works well on complex 3D surfaces.
