First, three elements of diamond circular saw cutting
There are three main indicators for measuring the cutting effect of diamond circular saw blades: efficiency, life, and processing quality.
Efficiency reflects the sharpness and productivity of the saw blade;
The life span reflects the durability of the saw blade, and normally is showned by the number of materials (like cubic meters, square meters, extended meters, slabs numbers, etc.) which one piece saw blade can cut.
Life is not showed as long as possible. It is better to combine with efficiency and which both can achieve good economics.
processing quality refers to the flatness, straightness, parallelism of the two sides, and edge integrity of the sawing surface.
Second, factors which affecting the cutting efficiency of diamond circular saw blades
There are many factors that affect the cutting efficiency of diamond circular saw blades. From a large perspective, there are two aspects of manufacturing factors and usage factors of saw blades.
Manufacturing factors include raw materials, manufacturing processes, ie diamond, binder, matrix and formulation, hot pressing, welding, cutting, correction and other factors;
The usage factors refer to the selection of the saw blade, the selection of the sawing machine, the selection of the sawing parameters, and the installation and operation of the saw blade.
Third, the selection of structure, size for Wanlong diamond circular saw blade
- Diamond circular saw blade steel base material and performance selection:
Sintered blade, high-frequency welded diamond circular saw blade steel base material is mostly used by high-quality spring steel 65Mn, 50Mn2V;
It is required that the hardness of the general welding saw blade steel base should be HRC35~42, the maximum surface roughness is Ra3.2μm, the surface must not have cracks, burrs, rust, the steel base must eliminate deformation force, micro crack, ensure the balance of tension, straightness, Shape requirements and apparent, intrinsic quality requirements;
Selection of steel structure of diamond circular saw
As seen from the surrounding structure of Diamond circular saw blade steel base :
it can be roughly divided into a continuous type and a water-slot type . The continuous type is mainly used for making hot-press saw blades,the edges mostly are thinned Great Wall teeth;
The water-slot type can be used for welding or hot pressing (the edge is also thinned Great Wall teeth);
Narrow water-slot type (small U-shaped, keyhole type) steel base used in medium-diameter saw blades for cutting weak abrasive or brittle materials (such as limestone, marble, microcrystalline stone, glazed tiles or granite), Wide water-slot type (large U-shaped) steel base is used in large saw blades or medium-diameter saw blades for cutting highly abrasive materials (such as sandstone, concrete, asphalt pavement, wall, refractory, etc.), which facilitates the large amounts of coolant flow into the cut notch for better chipping and cooling. Using a narrow water-slot type steel base, the segment can be made to depend on each other.
