What are the best practices for abs cnc machining to achieve smooth surface finishes?
Achieving an Ra 0.8μm surface finish on ABS requires managing its low glass transition temperature of 105°C. Industry data from 2025 shows that using uncoated carbide tooling with a 15° rake angle reduces heat by 35%, preventing surface melting. Maintaining a chip load of 0.005–0.010 IPT and a 10% flood coolant concentration eliminates 55% of …
