Marble Segments for natural soft stone cutting blades

Copper bond is typically softer and better suited for delicate materials like marble, as it ensures a cleaner cut with less chipping. Cobalt bond is harder and offers a longer lifespan, making it a common choice for high-volume applications like gang saws where stability is key.
The choice depends on the balance between finish quality and tool longevity. A copper-based matrix wears slightly faster, consistently exposing new diamond particles for a sharp edge. A cobalt-based matrix provides superior wear resistance, ideal for cutting abrasive marble types or for maximizing uptime.
For high-value, easily chipped marble, choose a copper bond to minimize finishing costs. For standardized, large-volume slabbing, a cobalt bond can lower your cost per cut by extending the replacement cycle.

A sandwich segment is a multi-layered diamond tool tip, typically with outer layers formulated for sharpness and an inner layer for durability. This design provides an excellent balance between cutting speed and tool life.
The outer layers initiate a clean, fast cut, which is crucial for preventing chipping on soft stones like marble. As the segment wears, the harder inner layer provides stability and extends the overall service life. This structure prevents the blade from becoming dull too quickly while maintaining a straight cutting path.
Using sandwich segments for marble cutting leads to higher efficiency. You get the initial sharpness needed for a pristine finish, plus the longevity required for cost-effective operation, ultimately boosting productivity and reducing the cost per square meter.

Diamond grit size directly impacts cutting speed and finish quality. Coarse grit (e.g., 30/40 mesh) cuts faster but leaves a rougher finish, while fine grit (e.g., 50/60 mesh) cuts slower but produces a smoother, cleaner edge.
For marble, which is a relatively soft and brittle material, a balance is crucial. Using a grit size that is too coarse can cause excessive chipping and micro-fractures. A medium-to-fine grit is often preferred because it minimizes edge damage, reducing the need for subsequent polishing and rework.
Choosing the right grit size optimizes your process. For rough slabbing, a medium grit might suffice. For finishing cuts or delicate onyx, a finer grit is necessary to achieve a premium, chip-free result, ultimately saving time and money on finishing.

It is strongly discouraged. Granite segments are engineered with a hard bond matrix and fine-grain diamonds to cut hard, abrasive stone. Using them on soft, brittle marble will likely cause severe chipping, fractures, and a poor finish.
The hard bond of a granite segment will not wear away fast enough on soft marble. This prevents new, sharp diamond particles from being exposed, causing the blade to "glaze over" and rub rather than cut. The result is excessive heat, material damage, and slow cutting speed. Conversely, a marble segment on granite would wear out almost instantly.
Always use segments specifically designed for the material you are cutting. Using the correct marble segment ensures a clean, fast cut, protects the valuable material from damage, and ultimately leads to a more efficient and profitable operation.

A gang saw is a large machine that uses multiple parallel blades moving back and forth to slice an entire stone block into slabs in a single operation. It is commonly used for slabbing softer stones like marble.
Diamond segments are brazed onto long, straight steel blades, with dozens of blades (often 80 to 120) mounted in a frame. The entire frame reciprocates, cutting through the block with a downward feed. The segments for gang saws are typically rectangular and often use a cobalt bond for maximum durability during these long, continuous cutting cycles.
This method is highly efficient for mass production of standard-thickness slabs. Using our optimized gang saw segments ensures uniform slab thickness, minimal chatter marks, and a long service life, which is critical for reducing downtime and operational costs.

EN 13236 is a European safety standard for superabrasive products, including diamond tools. For segments, it ensures they are manufactured and tested to meet stringent safety requirements, covering aspects like the strength of the bond to the blade core.
Compliance involves rigorous testing, such as verifying the bending moment and shear strength of the segment's connection to the steel blank. This ensures the segment will not detach during high-speed rotation, which is a critical safety hazard. Products compliant with this standard must also be clearly marked with information like maximum operating speed.
Choosing EN 13236 compliant segments, or blades made with them, provides a crucial layer of safety assurance. It minimizes the risk of catastrophic tool failure, protecting operators and equipment, and ensures you are using a product that meets internationally recognized safety benchmarks.
