Why Choose CMS for CNC PMMA Machining?

Optical-Grade Machining Expertise

We specialize in clear acrylic machining with minimal tool marks, ideal for lenses, light guides, display windows, and transparent covers.

Advanced Milling & Turning for Complex Shapes

Smooth contours, precise pockets, polished edges, and thin-wall structures achievable through optimized toolpaths.

Exceptional Surface Quality

PMMA supports near-optical clarity when machined and polished properly—CMS ensures clean, chip-free cutting.

Multiple Finishing Options

Flame polishing, vapor polishing, manual polishing, laser engraving, and surface texturing.

Rapid Prototyping & Stable Production

Fast delivery (2–5 days) with 60+ CNC machines, supporting prototype and mass production orders.

ISO-Certified Quality Control

Inspection for clarity, dimensions, and surface smoothness to meet optical component standards.

PMMA Material Properties

Property Value
Density 1.18 g/cm³
Hardness Rockwell M 90
Tensile Strength ~60 MPa
Transparency Up to 92% light transmission
Heat Resistance ~80°C
Chemical Resistance Moderate
Machinability Excellent

PMMA provides superior clarity but can crack under high-stress machining—CMS uses optimized feeds and sharp tools for clean results.

Standard tolerances are ±0.05 mm, and tighter tolerances down to ±0.02–0.03 mm are possible for simple geometries.

PMMA is brittle and prone to cracking under improper cutting conditions. CMS uses sharp tooling, optimized speeds, and controlled heat to ensure clean edges and crack-free surfaces.

Yes. With flame polishing, vapor polishing, or manual polishing, PMMA can reach near-glass transparency.

Finishes include polishing, deburring, edge smoothing, laser marking, and surface texturing (matte or gloss).

Yes. PMMA is naturally UV-resistant and commonly used for outdoor covers and light components.

No. PMMA is clearer but more brittle. Polycarbonate (PC) is stronger and impact-resistant. CMS can help select the right material.

Most PMMA prototypes ship in 2–5 days, depending on part complexity and finishing.

Yes. With 60+ CNC machines, CMS offers fast prototyping and scalable production for high-volume PMMA components.
