What alternative sawing option is there for diamond rough with considerable strain?

• A. Water-jet-guided laser sawing offers reduced weight.
• B. Water-jet-guided laser sawing offers lower precision.
• C. Diamond blocks are cut by water only.
• D. Water-jet-guided laser sawing provides greater working range, better focus, higher weight retention, and lower risk for strained rough.

Answer: (D)

When diamond rough shows considerable strain, the goal is to minimize heat and mechanical stress while keeping as much weight intact and maintaining precise control over the cut. Water-jet-guided laser sawing achieves this by combining cooling with a focused, guided cut. The water jet cools the slate of material as the laser works, which dramatically reduces thermal stress that would otherwise promote cracking in strained areas. The laser’s precise guidance enables a very clean kerf and accurate positioning, so you can navigate around or through stressed zones without initiating fractures. This approach also tends to preserve more weight because there’s less material lost to cracks or chipping, and it broadens the workable range of the rough by enabling cuts in geometries that are difficult for conventional sawing. The other options don’t offer the same balance of heat management, precision, and weight retention needed for strained rough.
