Monocrystalline silicon double station square machine 6/8/12 inch burr ≤0.5mm high precision ±0.05mm

In the field of semiconductor materials processing, monocrystalline silicon two-root vertical open-mechanism island building is a highly specialized integrated production unit dedicated to precisely cutting cylindrical monocrystalline silicon rods (Ingot) into square or rectangular silicon blocks (Grit or Brick) in preparation for subsequent slicing (such as making silicon wafers). The core equipment is a two-root vertical cutting machine, and the "manufacturing island" refers to the automatic and intelligent processing system built around the equipment.

Core function

· Processing objects: monocrystalline silicon rods (usually Φ6 inches to Φ12 inches, 1-2 meters in length).

· Core task: Cutting four sides of a cylindrical silicon rod vertically with a double saw blade to form a high-precision square/rectangular silicon block (retaining the core and reducing material waste).

· Key indicators: cutting accuracy (±0.05mm), surface flatness (Ra≤0.5μm), edge breakage control (≤50μm).
