Acrylic, also known as PMMA, is valued for its crystal-clear transparency, smooth finishing capability, and excellent stability when machined, making it ideal for light-guiding components, display elements, and protective covers. Its balanced strength-to-weight ratio and resistance to UV and weathering also make it suitable for both indoor precision assemblies and demanding outdoor applications.
Yes, acrylic (PMMA) can be precisely CNC machined. Its smooth, rigid nature allows for clean cuts, detailed shapes, and polished surfaces, making it ideal for both functional and decorative components.
Acrylic machines well, offering excellent clarity, dimensional stability, and the ability to hold tight tolerances, which makes it suitable for a wide range of applications from displays to protective covers.
Yes, most plastics can be CNC machined. Materials like acrylic, POM, ABS, PC, and PEEK can be shaped accurately while maintaining their mechanical and aesthetic properties, allowing for both prototyping and production parts.
Materials that are extremely brittle, highly abrasive, or very soft may be challenging or unsuitable for CNC machining. Examples include glass, ceramics without special tooling, certain foams, and some composites that can delaminate under cutting forces.
Cast acrylic is generally preferred for CNC machining due to its superior clarity, strength, and ability to produce smooth edges without cracking or chipping, compared to extruded acrylic, which is better for simpler cuts or larger sheets.
