Why Choose Acrylic CNC Machining for Clear Prototypes?
Acrylic CNC machining utilizes high-speed spindle rotation to achieve a surface roughness (Ra) as low as 0.2 micrometers, far superior to the 3.2 micrometer standard in vacuum casting. With a light transmission rate of 92%, PMMA remains the gold standard for optical-grade prototypes, provided that thermal control maintains the cutting temperature below the 105 degrees […]
