What are the challenges of machining intricate details into PVC blocks?

Machining intricate details into PVC blocks presents several unique challenges due to the material's properties. First, PVC's softness can lead to deformation or burring during cutting, requiring sharp tools and precise control. Second, its low melting point makes it prone to heat buildup, which can cause melting or warping if not managed properly. Third, tool wear is accelerated because PVC's abrasiveness dulls cutting edges faster than harder materials. Additionally, achieving fine details demands high spindle speeds and careful feed rates to avoid chipping or rough edges. Finally, dust and chips generated during machining can cling to surfaces, complicating cleanup and potentially affecting precision. Addressing these challenges requires specialized tooling, cooling strategies, and meticulous process planning to ensure high-quality results.
