VAD Chemical Vapor Deposition Preform Lathe from Japan
This lathe-based system deposits silica soot layers via Vapor Axial Deposition (VAD) to build cylindrical optical fiber preforms, followed by sintering. It rotates the target mandrel during deposition for uniform growth. HTS 8475.21.00.00 covers such machines essential for modern optical fiber manufacturing.

Import Tips
• Document CVD process parameters specific to silica glass for telecommunications fiber
• Avoid classifying as general lathe (8458); emphasize preform deposition function
• Include safety data for chemical precursors used in deposition
