Key Performance Ranges of Acrylic
PMMA delivers high transparency, low density and stable outdoor performance for optical, protective and visual components.
Property values represent common PMMA grades. Final selection follows the material datasheet, loading, temperature and chemical exposure.
Acrylic Material Selection
Choose the Right type of Acrylic
Select Acrylic by dimensional stability, optical performance, impact resistance, color and service environment.
Cast Acrylic
Low internal stress, stable dimensions and excellent edge polishability support precision CNC machining.
- Material characteristics
- High clarity, clean machined edges and strong dimensional stability.
- Application environment
- Optical equipment, displays, laboratory fixtures and indoor assemblies.
Final selection follows the drawing, tolerance, transparency, loading and operating temperature.
Machining Capability
Controlled CNC Machining for Acrylic Parts
Sharp tooling, stable workholding and controlled cutting heat protect dimensions, edges and optical surfaces.
| Standard Tolerance | ±0.05 mm |
|---|---|
| Precision Features | ±0.02 mm |
| As-Machined Roughness | Ra 0.8–3.2 μm |
| Minimum Wall Thickness | From 1.5 mm |
| Material Forms | Sheets, rods, tubes and blocks |
| Production Range | Prototype, small batch and repeat production |
Sharp tools and chip evacuation prevent melting and edge deformation.
Corner radii and stable wall thickness reduce cracking and chipping.
Controlled fixture pressure protects flatness and polished surfaces.
Finishing allowance is reserved for optical and display surfaces.
Acrylic Finishing
Surface Finishes for CNC Machining Acrylic Parts
Finishing improves transparency, appearance, glare control, branding and surface texture.
Polishing
Restores gloss and transparency on machined edges.
Protective Coating
Adds scratch, glare or fingerprint resistance.
UV Printing
Adds logos, labels, graphics and identification.
Frosted Finish
Creates a uniform matte surface and diffuses light.
Custom Texture
Produces functional or decorative surface patterns.
Acrylic Machining FAQ
Plan Your Custom Acrylic Parts
Practical answers about CNC cutting, tool selection, machining speed and project cost.
Can acrylic be cut with a CNC machine?
Yes. CNC milling, routing and turning produce accurate holes, pockets, contours, threads and optical features in acrylic sheets, rods, tubes and blocks.
What type of CNC bit is best for cutting acrylic?
A sharp polished carbide O-flute or single-flute cutter provides clean chip evacuation and limits heat. Polished two-flute carbide tools suit rigid milling operations.
What is the best CNC cutting speed for acrylic?
For 3–6 mm carbide router tools, 12,000–20,000 rpm is a practical starting range. Feed must produce clean chips instead of dust while preventing edge melting.
How can custom acrylic machining costs be reduced?
Use standard stock thicknesses, practical tolerances, adequate internal radii and consistent wall sections. Combining similar parts into one order also reduces setup cost.
Can threads be CNC machined into acrylic parts?
Yes. Coarse threads, adequate wall thickness and generous edge distance reduce cracking. Metal threaded inserts provide stronger joints for repeated assembly.
