CNC Semiconductor Wafer Surface Lapper from Germany
A numerically controlled lapping machine that achieves ultra-flat wafer surfaces critical for semiconductor fabrication by using abrasive slurries on metal or cermet surfaces. Falls under HTS 8460.24.00.80 as an NC grinding/lapping machine for finishing semiconductor wafers, distinct from gear finishing. Essential for bringing wafers within tight dimensional tolerances as per statistical notes.

Import Tips
• Include detailed process descriptions showing lapping for flatness tolerances in semiconductor wafer prep to distinguish from general polishing machines
• Label as 'semiconductor wafer processing equipment' on commercial invoice for proper statistical reporting
