Got clear acrylic parts that still look hazy or crack after machining?

Acrylic can machine beautifully — until you see the surface finish or stress cracks show up later. 😕

🛠️ For CNC machined acrylic (PMMA), polishing isn’t just about cosmetics — it’s what transforms a milled part with tool marks into one with clear, smooth, and optically usable surfaces. But the wrong method or too much heat can cause haze, burn marks, or micro-cracks. 🔍

📘 Here’s a practical guide to the most common acrylic polishing methods — from hand and machine polishing to production-grade CNC-controlled polishing — and how engineers decide which approach works best👇
