SGS180-90
The SGS180-90 is an industrial-grade diamond wire cutting machine designed for ultra-large optical glass blocks, particularly high-purity quartz. With a cutting capacity of up to 1800 mm in length，900 mm in width and 600 mm in height, this machine is ideal for large-format material processing in research institutes and industrial glass production lines.
Key Features of SGS180-90
Purpose-Built for Oversized Quartz Blocks
Engineered specifically for cutting ultra-large quartz glass materials up to 1800 mm in length and 900 mm in width and height, including high-purity blocks used in optical and semiconductor industries.
Oscillating Endless Diamond Wire Cutting
Equipped with a top-down cutting system that integrates high-speed endless diamond wire and lateral oscillation, enabling smooth slicing with built-in polishing effect. This results in reduced surface roughness and minimal subsurface damage.
High-Speed Cutting with Clean Surface Finish
The oscillating motion increases cutting efficiency and produces mirror-like surfaces, eliminating the need for secondary polishing in many applications.
Scalable Structure for Extra-Large Loads
Thanks to the scalable gantry structure and adjustable stroke, the SGS180-90 can handle heavy and oversized blocks with no compromise in cutting quality or mechanical stability.
Side-Open Work Area for Easy Loading
Designed with an open-sided loading platform, enabling crane or forklift access to place large glass blocks easily and safely.
Customizable Clamping System
Supports integration of magnetic fixtures, vacuum chucks, or custom mechanical holders for securing large and heavy optical materials during slicing.
Low Kerf Loss and Precision Control
Delivers narrow kerf widths (0.4–0.6 mm) with highly repeatable parallel cuts. Ideal for applications where material conservation and cut uniformity are critical.
Fully Programmable Control System
The touchscreen interface allows users to adjust wire speed, oscillation amplitude, stroke, and cutting cycles for batch or prototype production with consistent results.
Stable and Low-Stress Cutting
The abrasive, oscillating motion combined with vertical top-down feeding produces ultra-low cutting force, preventing edge chipping, internal fractures, or material shift.
