When it comes to precision cutting in the stone industry, diamond segments are the core component that determines performance, efficiency, and durability. Whether you're cutting marble, granite, or engineered stone, choosing the right diamond segment and understanding how it's made can significantly impact your results.
In this comprehensive guide, SANG Diamond Tools walks you through everything you need to know about diamond segments—from how they are made, to the different segment shapes, and how to choose the right one based on your cutting needs.
What Is a Diamond Segment?
A diamond segment is the functional part of diamond tools like diamond saw blades, grinding shoes, and core drill bits. It is composed of diamond particles and metal bond powder, which are carefully engineered to deliver high performance for different cutting applications.
How Are Diamond Segments Made?
1. Preparation of Diamond and Metal Powder
The first step is sourcing high-quality diamond particles and metal powders. The formulation varies based on the cutting material. For example, granite requires a different diamond-metal mix than marble.
2. Mixing the Compound
Both components are mixed thoroughly—often for over 2 hours—to ensure uniform distribution. This step is critical to segment strength and cutting consistency.
3. Cold Pressing
The mixed compound is pressed into segment layers using an automatic cold-pressing machine. Depending on the cutting application, segments may have multiple layers:
Side Layers (higher diamond concentration)
Middle Layers (lower concentration)
Transition Layers (no diamond)
4. Die-Filling
The layered powders are placed into molds in the correct sequence for hot pressing.5. Hot Pressing
The hot pressing process uses high temperature and pressure to bind the layers into a solid segment. This step defines the hardness, density, and overall durability of the segment.
6. Mold Removal
After cooling, the diamond segments are removed from the mold, ready for finishing.
7. Sand Blasting
Sand blasting removes burrs and smoothens the surface of the segment for optimal performance.
8. Inspection
Each segment undergoes strict quality control, including checks for dimensional accuracy, weight, and appearance.
9. Packing
Finally, the high-quality diamond segments are carefully packed and prepared for shipping.
Common Shapes of Diamond Segments and Their Applications
The shape of a diamond segment directly impacts cutting efficiency, sharpness, and lifespan. Here's a breakdown of the most common types:
1. Rectangular (Cube) Segments
Best for: Gang saw blades, large marble saw blades
Why: Provides maximum cutting surface and efficiency, ideal for softer stones like marble.
2. R-Shape (Fan-Shaped) Segments
Best for: Medium-diameter marble and granite saw blades
Why: Excellent for curved slab cutting and general-purpose applications.
3. M-Shape Segments
Best for: Hard stone cutting
Why: Sawtooth design enhances sharpness, increases cutting speed, but may reduce lifespan.
4. K-Shape Segments
Best for: Mining and long-duration cutting
Why: Focuses on durability and consistent performance over time.
5. T-Shape Segments
Best for: Applications requiring a balance of sharpness and lifespan
Why: High resistance to wear and impact, but at a higher cost.
6. W-Shape Segments
Best for: Serrated saw blades, microcrystalline stone, artificial granite
Why: High sharpness and sustained cutting performance.
