Prism Cutting Machine
The SGR 20 is a specialized diamond wire saw designed for cutting optical glass and ceramic prisms with high precision. Equipped with a programmable rotary worktable, the system can rotate the workpiece to specified angles for multi-faceted slicing—making it ideal for producing triangular, quadrilateral, pentagonal, and polygonal prism blanks.
KEY FEATURES
- 1. Multi-Angle Prism Cutting Functionality
The rotary worktable can rotate 360°, allowing users to set precise prism angles. The system supports automated generation of triangles, squares, pentagons, octagons, and more—ideal for producing optical prism blanks. - 2. Automatic Slicing Capability
Operators can program different slicing thicknesses within a single job. Once the thickness and quantity are set, the machine automatically performs the full slicing sequence without supervision. - 3. Stable Vertical Structure with Enclosure
The SGR 40 uses a fully enclosed upright design with a steel frame and observation window, providing both safety and easy visual monitoring during the cutting process. - 4. Servo-Driven YZ Motion with Ball Screws
The slicing axes (Y and Z) use servo motors, linear guides, and ball screws for precise positioning—repeatability up to ±0.01 mm and feed resolution of 0.01 mm. - 5. Touchscreen + Manual Control Interface
A user-friendly English-language PLC system enables parameter setup via touchscreen, with a handheld controller for easy manual alignment and override. - 6. Integrated Water Cooling & Lubrication
Equipped with a water circulation system and automatic oil lubrication to ensure a clean, stable cutting environment.

CUTTING METHODS FOR PRISMS: COMPARISON OVERVIEW
Understanding the different cutting methods used in prism production helps you see where the SGR 40 fits in. Here’s a quick look at each method’s strengths and limitations:
| Cutting Method | Suitable for Prisms | Advantages | Limitations | Common Materials |
|---|---|---|---|---|
| SGR 40 (Rotary Wire Saw) |  Yes | Programmable angles, clean edges, multi-face slicing | Cannot cut curves | Optical glass, ceramic prisms |
| Manual Cutting + Hand Polishing |  Limited | Low-cost, simple setup | Poor repeatability, labor-intensive | K9, small educational prisms |
| CNC Profile Grinding | Yes | Extremely high accuracy, angle control | Requires pre-cut blanks, expensive | Glass, optical crystals |
| Laser Cutting (High Power) | Conditional | Fast, non-contact | Heat-affected zone, edge cracking risk | Some glasses, low-hardness optics |
| Waterjet Cutting | For rough shaping | Any shape, handles large blocks | Rough edges, requires rework | Quartz, ceramics |
| ID Saw |  No | Precise thin slicing | No angle or multi-surface capability | Flat wafers, ceramics |

What is the maximum thickness the machine can handle for cutting?
What is the difference between this wire saw and BAND SAW?
The cutting speed would be similar, but wire saw’s cut surface quality is far more better. and the kerf loss is smaller.
