When circular saw blades are used for stone cutting, they usually require special designs and materials to cope with the high hardness, brittleness and wear resistance of the stone. The following is key information about circular saw blades for stone cutting, covering aspects such as selection, use and maintenance:
1. Types of circular saw blades for stone cutting
Diamond saw blades (most commonly used)
The blade head is embedded with diamond particles and fixed to the base through high-temperature sintering or electroplating processes.
Diamond is extremely hard and can efficiently cut hard stones such as marble, granite, and tiles.
Classification:
Sintered diamond saw blades: high temperature resistance, long life, suitable for continuous operation.
Electroplated diamond saw blades: high sharpness, but short life, suitable for fine cutting.
Tungsten carbide saw blades
Used for softer stones (such as sandstone, limestone) or low-intensity cutting, lower cost, but not as wear-resistant as diamond.
2. Saw blade structural features
Diameter: Select according to the thickness of the stone, commonly used diameter is 100mm-1200mm (large stone cutting machines use larger sizes).
Tooth shape:
Continuous teeth: smoother cutting surface (suitable for tiles and marble).
Segmented teeth (wolf teeth): reduce friction and heat, suitable for high-hardness stones such as granite.
Base material: high-carbon steel or alloy steel, high rigidity and deformation resistance.
Sink design: helps dissipate heat and remove chips, prevent saw blade overheating and stone edge collapse.
3. Selection suggestions
Stone type:
Soft stones such as marble and limestone: choose diamond saw blades with high sharpness (such as electroplating type).
Hard stones such as granite and quartzite: sintered diamond saw blades with strong wear resistance and segmented tooth design are required.
Tiles and artificial stones: thin diamond saw blades to avoid edge collapse.
Cutting method:
Wet cutting: Cooling water is required to reduce dust and extend the life of the saw blade.
Dry cutting: Use a saw blade with heat dissipation holes or special coating, but it will wear faster.
4. Precautions for use
Installation: Make sure that the saw blade matches the shaft diameter of the equipment and the flange is tightened to avoid eccentric shaking.
Speed: Strictly operate according to the rated speed marked on the saw blade. Too high speed will cause overheating or breakage.
Feed speed: Slowly and evenly advance to avoid forced pressure causing the cutter head to fall off or the stone to break.
Cooling: Maintain sufficient water flow during wet cutting; dry cutting requires intermittent operation to prevent overheating.
Safety protection: Wear goggles and dust masks, and stay away from the direction of rotation of the saw blade.
5. Maintenance and care
Cleaning: Clean the stone powder remaining on the cutter head after use to prevent hardening from affecting cutting efficiency.
Trimming the cutter head: After long-term use, the diamond particles may be passivated, and refractory bricks or special trimmers can be used to sharpen the blade.
Storage: Dry environment, avoid rusting of the base or moisture on the blade.
Regular inspection: Check the wear of the saw teeth and deformation of the base, and replace the damaged saw blade in time.
6. Common problems and solutions
Slow cutting speed:
Reason: Diamond blade is blunt, the stone is too hard, and the saw blade does not match.
Solution: Replace the saw blade or trim the blade to reduce the feed speed.
Saw blade vibrates or makes abnormal noises:
Reason: Unstable installation, deformation of the base, and loose fixation of the stone.
Solution: Reinstall the saw blade and check the main shaft and flange of the equipment.
Blade falls off:
Reason: Overheating, impact with hard objects, welding process defects.
Solution: Replace the saw blade to avoid long-term high-load work during dry cutting.
Summary: The core of stone cutting circular saw blade lies in the quality and matching of the diamond blade. Reasonable selection of saw blades according to the hardness of the stone, cutting method (wet cutting/dry cutting) and equipment parameters, and attention to operating specifications and maintenance can significantly improve cutting efficiency and saw blade life.
