What is concrete saw blade

 

• It is used for cutting and pouring concrete for more than 24 hours and renovation of old roads, with fast cutting speed, grinding resistance and long service life;
• The use of pre-alloyed powder as the matrix achieves the purpose of reducing the ineffective shedding of diamonds and exerting its use effect to the greatest extent. Can cut 1500～3000m;
• Water cutting, suitable for road cutting machine;
• The laser welding process is adopted, the diamond segment is firmly combined, and it is not easy to drop the teeth;
• For cutting concrete walls and brick walls;
• U-shaped teeth improve the chip removal performance of the saw blade and increase the cutting speed;
• Strong cutting ability to reinforced concrete;
• Shorter cutting time and lower construction cost;
• The diameter of the saw blade is 600~1200mm;
• Other specifications can be produced according to customer requirements.

Types of Concrete Saw Blade

Designed with lifetime in mind, these blades feature drop segments and high diamond concentration to tackle cured concrete efficiently. Professional saw blades with medium-soft bonding formula for cutting concrete and reinforced concrete.

Diamond blades laser welded for use on green concrete. They are for early entry cutting of control joints within one to two hours of concrete finishing. The 1" bushing fits Soff-Cut saws and all most saw on the market.

When you use a diamond asphalt cutting blade, the exposed edge will wear away the more it cuts through the asphalt. This is conducive for sustained cutting since the wear on the blade can expose new layers of grit.

You may find asphalt cutting blades in both wet and dry varieties. Dry cutting blades have a softer bond than wet cutting blades, and wet cutting blades require water in order to cool and lubricate a cut while cutting.

What Should I Pay Attention to when choosing concrete saw blade

1. Selection of sintering process for concrete cutting blade.
In the process of gradually increasing the temperature, the degree of densification of the cutter head matrix is also increasing, and the bending strength is also increased. When the holding time is prolonged, the flexural strength of the blank matrix and diamond agglomerates will first increase and then decrease. At this time, the sintering time at 800°C can be selected to be 120s to meet the requirements of improving the performance of concrete cutting blade.

2. Selection of diamond particle size of diamond segment.
When the diamond particle size of the cutting blade is coarse and is a single particle size, the diamond segment. of the concrete cutting blade is sharp and the sawing efficiency is high, but the bending strength of the diamond agglomeration decreases; The blade segment will be more durable, but less efficient. Taking into account comprehensively, it is more appropriate to select the diamond particle size as 50/60 mesh.

3.Selection of matrix diamond distribution concentration
Within a certain range, when the diamond concentration changes from low to high, the sharpness and sawing efficiency of the cutting blade will gradually decrease, and its service life will gradually extend; but when the concentration is too high, the cutting blade will become dull. Conversely, with low concentration and coarse particle size, the efficiency will be improved. Taking advantage of the different functions of each part of the diamond segment during sawing, different concentrations are used (that is, in a three-layer or multi-layer structure, a lower concentration can be used for the middle layer), and a middle concave is formed on the diamond segment during the sawing process of the cutting blade. The groove can help to prevent the deflection of the cutting blade, thereby improving the quality of stone processing.

4. the choice of diamond strength in the matrix
An important indicator to ensure cutting performance is the strength of the diamond. If the strength of diamond is too high, the crystal will not be easily broken, the abrasive grains will be polished during use, and the sharpness will be reduced, which will lead to poor processing performance of the tool; when the strength of diamond is low, it will be easily broken after being impacted. The diamond strength of the road cutting sheet should be selected to be 130-140N.
