Diamond wire cutting machine SGR 20

for glassfor ceramicssheet metal

Product Overview
The SGR 20 is a diamond wire saw engineered for precision cutting of optical glass and ceramic prisms. It features a programmable rotary worktable for multi-faceted slicing, enabling automated production of triangular, quadrilateral, pentagonal and other polygonal prism blanks.

Key Features

• Multi-angle prism cutting: rotary worktable with 360° rotation and programmable angles for automated generation of triangles, squares, pentagons, octagons and other polygonal blanks.
• Automatic slicing: programmable slice thickness and quantity for unattended batch processing.
• Enclosed vertical structure: steel frame with observation window for safe, visible operation.
• Servo-driven YZ motion with ball screws: servo motors, linear guides and ball screws provide positioning repeatability up to ±0.01 mm and feed resolution 0.01 mm.
• Touchscreen and manual control: PLC touchscreen interface for parameter setup and handheld controller for alignment and manual override.
• Integrated water cooling and lubrication: closed water circulation and automatic oil lubrication for stable cutting conditions.

Working Principle
An endless diamond wire combined with a programmable rotary worktable, servo-driven YZ axes and automatic tension control performs clean, repeatable slicing of multi-faceted optical components, ensuring consistent prism geometry across materials.

Applications

• Production of right-angle and polygonal optical prisms, beam splitters, wedges and angled windows.
• Manufacture of optical components for laser optics, imaging, AR/VR, telescopes and sensor windows.
• Precision research laboratories and universities for prototyping non-standard prism geometries.
• Crystal and laser-optics factories for slicing YAG, BBO, LBO and similar crystals prior to polishing and coating.

Customer Use Cases & Advantages

• Multiple-surface slicing in a single programmed run without re-clamping; angle accuracy and surface finish suitable for downstream polishing.
• High-speed endless wire cutting and high-rigidity cast structure deliver stability and reduced vibration for long-term accuracy.
• Automatic constant-tension system extends wire life and reduces breakage during long operations.
• User-friendly PLC and servo interface, modular design and automatic lubrication minimize downtime and maintenance.
