Advantages & Disadvantages of Acrylic CNC Machining
Advantages
- Exceptional clarity – ideal for transparent or semi-transparent components
- Excellent aesthetics – compatible with polishing and engraving
- Good dimensional accuracy – holds tight tolerances for display or fitment
- UV resistance – suitable for indoor and outdoor applications
Disadvantages
- Brittle nature – more prone to cracking than polycarbonate or ABS
- Lower impact resistance – not suitable for high-stress environments
- Edge chipping – requires precise CNC technique and tooling
- Heat sensitivity – PMMA may melt or deform under high-speed machining if not carefully controlled
Surface Finishing Options for CNC Acrylic Parts
To enhance both the appearance and functionality of your CNC machined acrylic components, we offer a range of surface finishing services. Whether you need glossy polished edges, frosted textures, or precise engraving for branding and labeling, our finishing processes ensure your cnc milling acrylic parts achieve the perfect balance of clarity and durability.
Standard finish with visible tool marks; suitable for functional prototypes and internal components.
Uses abrasive media to create a uniform matte or satin finish; also improves coating adhesion on plastic or metal surfaces.
Adds logos, text, or identification marks via silk screen or pad printing, ideal for branding or part tracking.
Removes machining marks and evens out surface texture; ideal for prototypes and parts where appearance is not critical.
Painting and powder coating provide colorful, durable, and corrosion-resistant finishes.
Deposits metal layers such as nickel or chrome on parts, improving wear resistance, conductivity, and aesthetic quality.
Produces a smooth, glossy finish; commonly applied to plastics like PC or PMMA for enhanced clarity and premium look.
Chemical treatment for ferrous metals, creating a dark, corrosion-resistant surface with minimal thickness.
Electrochemical process for aluminum that enhances corrosion and wear resistance, with options for colored finishes.
