Quick Answer

Choose gang saw segments by material hardness, segment height, width, bond hardness and diamond concentration. Hard stone needs harder bonds and higher concentration; softer stone needs softer bonds. Always match the segment footprint to your blade's slot.

Key Segment Specs

• Height: how much usable diamond depth the segment carries.
• Width: must match the blade body thickness and kerf target.
• Bond hardness: hard for granite, softer for marble and abrasive stone.
• Diamond concentration: higher for hard stone, lower for softer material.

How to Choose the Right Segment

Material	Bond	Concentration
Hard granite	Hard	High
Medium granite	Medium-hard	Medium-high
Marble	Soft	Medium
Sandstone / abrasive	Soft	Low-medium

How to Use It Correctly

• Confirm slot width and segment height before ordering.
• Keep water flow high — gang saws run hot.
• Feed steadily; forcing causes segment loss and blade deflection.
• Inspect segment wear and replace the whole set evenly.

Frequently Asked Questions

Q: What determines segment price?

A:Diamond quality and concentration, plus segment size. High-concentration hard-stone segments cost more.

Q>How long do gang saw segments last?

A:It varies widely — hours to days of cutting, depending on stone hardness and feed. Track square meters cut per set.

Q: Can segments be re-welded or re-used?

A:Used segments are usually replaced, not re-used. Matching sets cut evenly and keep the blade balanced.

Conclusion

Specify the segment for your material, machine slot and target output. The Diamond Segment for Multi-Blade Ganged Saw — JOY-MB-S serves multi-blade ganged saws, while the Quarry Blade Segment (Single Blade) — JOY-QB-S suits single-blade quarrying.
