High-Precision Optical Prism Wire Cutting Machine
Model: SGR 40 – Automatic Prism & Cube Cutting with Endless Diamond Wire
The SGR 40 Precision Optical Prism Wire Cutting Machine is designed for high-accuracy cutting of optical glass and crystal materials into cubes, prisms, and multi-faceted components — all achieved with a single clamping operation.
By combining automatic rotary cutting, multi-angle machining, and endless diamond wire technology, the SGR 40 delivers exceptional precision, automation, and surface quality, making it an ideal solution for modern optical manufacturing.




One Clamping, Complete Prism Processing
Traditional prism cutting often requires:

Multiple clamping steps

Manual repositioning

Accumulated alignment errors

High labor involvement

The SGR 40 eliminates these issues.

With one-time clamping, the machine can:

Automatically cut cubes and various optical prisms

Perform multi-angle cutting on four sides

Maintain consistent accuracy across all faces

This significantly improves dimensional consistency while reducing setup time and operator dependency.

Fully Automatic Rotary Cutting – True Multi-Axis Capability

A key advantage of the SGR 40 is its automatic rotary worktable, which allows the workpiece to rotate to any programmed angle during cutting.

This enables:

Precise prism angles and complex geometries

Seamless four-side machining without re-clamping

Stable and repeatable cutting for batch production

Whether producing standard cubes or custom prism shapes, the SGR 40 ensures high accuracy and process reliability.

Multi-Function Integration: Prism Cutting & Automatic Slicing

The SGR 40 is not limited to prism machining.

It also supports automatic slicing, allowing users to process different product types on the same machine.

This multi-function integration helps:

Reduce equipment investment

Increase workshop flexibility

Adapt quickly to different production tasks

Endless Diamond Wire Technology – Speed Meets Surface Quality

The SGR 40 uses a closed-loop (endless) diamond wire that moves continuously in a single direction, without reversing.

This advanced cutting system provides:

Ultra-high linear wire speed up to 80 m/s

Stable cutting force with minimal vibration

Smooth cutting surfaces with no chipping or edge damage

Narrow kerf width for maximum material utilization

Compared with conventional cutting methods, the endless wire system delivers both higher efficiency and superior optical surface quality.

Smaller Kerf, Higher Yield, Better Finish

Thanks to the new-generation diamond wire cutting tool, the SGR 40 achieves:

Reduced material loss

Cleaner edges and smoother surfaces

Improved yield for high-value optical materials

This is especially important when processing optical glass, crystals, and precision components, where material cost and surface integrity are critical.

Ideal Applications

Optical glass cubes and prisms

Precision optical components

Crystal and technical glass materials

R&D laboratories and optical production lines
