Overview
SGI 20 is a compact, high-precision CNC endless diamond wire saw specifically designed for cutting small glass and ceramic components with complex contours. It supports both straight slicing and irregular 2D profiling, suitable for optical labs, filter manufacturers, and R&D institutions.

Key Features

• Dual cutting functions: straight slicing and contour shaping with DXF import for complex profiles.
• Compact vertical gantry structure providing mechanical rigidity; accommodates workpieces up to 200 × 200 × 200 mm.
• High-precision motion system: Y/Z travel 200 × 200 mm driven by servos with lead screws and guide rails; positioning ±0.01 mm; cutting accuracy ≤ 0.03 mm.
• DXF-compatible CNC software with built-in CAM for arcs, diagonals and straight-edge combinations.
• Endless electroplated diamond wire Ø 0.35–0.8 mm driven by high-speed servo; cutting loop length 1797 mm.
• Automated oil lubrication and water cooling with built-in tank and circulation.
• Safety features: wire-break detection, emergency stop, electrical protections and proximity sensors.

Applications

• Optical filter glass (narrowband filters, IR filters) and laser optics blanks.
• Technical ceramics (Al2O3, AlN, sintered ceramics for RF modules, power electronics, thermal substrates).
• Quartz plates, microlenses, small quartz windows, lens blanks and optical waveguide substrates.
• Custom sensor windows and substrates for MEMS, LiDAR and spectroscopy.

Cutting Demonstrations / Comparative Notes
The machine demonstrates smooth operation and clean edge quality in demonstrations, suitable for filter glass slicing and complex ceramic profiles. Compared with other technologies, CNC diamond wire saws such as the SGI 20 provide fully supported complex shapes via DXF import, high precision (≤ 0.03 mm), minimal thermal impact and excellent surface finish.
