Refers to the abrasive particle size, particle size marker used. metal grinding disc‍ According to the requirements of abrasive used, the use of sieving and water into the legal system selected a variety of different thickness granularity. Coarse particle size 40μm, multi-use screening method, according to their size into 25 granularity, denoted as: 

Narrow range: 16/18 to 325/400 width range: 16/20 to 60/80 

Each particle size range of basic grains group size ranges, each basic particle swarm is two adjacent mesh sieve to determine the nominal size. Of fine particle size of 40μm, the use concrete cutting wheels‍ of sedimentation. Different size for different machining accuracy and roughness.

concrete cutting blades Concentration

The unique characteristics of superhard abrasive. A diamond grinding wheel, for example, it refers to the percentage of the corresponding wheel of the diamond flat cutting disc‍ layer included in each cubic centimeter volume of diamond quality. The concentration of diamond abrasive is 100% base value equal to 0.88g/cm3 (4.4 克拉 / cm3); When the diamond when the density is 3.52 g/cm3, (CBN density of 3.47 g/cm3), this value corresponds to the volume of 25%, all other concentrations were calculated this ratio shown in Table 1. 

Volume percent concentration in a simple linear relationship: 

V = 0.88c / γ where: 

V - volume, cm3; 

c - concentration,%; 

γ - abrasive density (generally the diamond concrete cutting blades‍ is 3.52g/cm3, CBN is 3.47g/cm3). 

The density of the diamond into the formula, V (%) is the concentration c (%) of l / 4, i.e., 

V = 0.25c‍

concrete cutting discs cubic boron nitride

Tool CBN (cubic boron nitride) abrasives as raw materials, namely a metal powder, a resin powder, ceramic and metal plating as binder, into various shaped articles, for concrete cutting wheels‍ grinding, polishing, grinding, called CBN abrasive .

CBN abrasive structure 

CBN (cubic boron nitride) grinding the general structure of the operating layer, the substrate, the buffer layer consists of three parts. 

CBN layer known as a working layer, the abrasive, binders and fillers, is abrasive working portion. The buffer layer is also called non-CBN layer of binding agent, and a filler metal powder is firmly attached to the part of the base layer of the CBN. 

The base is machined from aluminum, steel or flat cutting disc‍ made ​​of bakelite, supporting work from abrasive layer and the role of chucking.

LEMAN concrete cutting wheels good grinding performance, good surface quality

Since the CBN abrasive grains can maintain long-term micro-edge sharpness, will be processed workpiece machining accuracy and surface roughness values ​​have reached concrete cutting blades‍ more satisfactory results, and therefore can improve the durability of the workpiece 10% -30% . So even if the batch processing of the workpiece, the shape will always get higher accuracy and consistency. CBN grinding wheel to achieve high dimensional accuracy and low surface roughness, surface cracks and burns easily, a small residual stress. Improved surface quality, generally no cracks, not burned, and the residual stress can be obtained, significantly improve the fatigue strength of the workpiece, generally, the durability of the workpiece to be ground can be increased by 30-50%. 

6, wear resistance, long life 

CBN grinding wheel ratio up to 3500-5500, a hundred times higher than normal corundum grinding wheels, diamond grinding higher than 3-5 times. 

7, environmental pollution, energy saving 

Without too much powder dust. 

8, high efficiency, good overall economic concrete cutting wheels‍ efficiency 

Grinding sharp, small grinding force, CBN grinding wheel dressing long period, less the amount of dressing, long replacement time; long life cycle, grinding ratio, getting a better economy, use good shape retention, without regular Replace the wheel and wheel dressing, saving time and improving working conditions conducive to machining operations. 

CBN is not suitable for grinding hard alloy and non-metallic materials. Grinding at a high temperature, CBN case of alkaline aqueous chemical reaction occurs, CBN wheel at 300 ℃ alkaline solution are decomposed in boiling water can trace decomposition results crystalline grains will be destroyed, so the grinding only use oil-based coolant, not water-based coolant.‍

The nature of the introduction and application of Concrete cutting wheels

  Concrete cutting wheels in a wide range of different wheels can cylindrical, inner circle, plane and a variety of type faces and other parts of coarse grinding, semi-fine grinding and grinding, as well as concrete cutting wheels and slotting, respectively. Central wheel with abrasive and made ​​binding agents have rounded abrasive vias. Many types of grinding wheels, different wheel can cylindrical, inner circle, plane and a variety of type faces and other parts of coarse grinding, fine grinding and cutting wheels   half, as well as concrete cutting wheels and slotting, respectively. Conventional abrasive concrete cutting wheels characteristic has the shape, diameter, thickness, diameter milk, abrasive, grain size, hardness, binders and organizations. Resistance when turning the wheel rupture under the centrifugal force. Since the tensile strength is lower than the compressive grinding or flexural strength, tensile strength usually measured wheel, the size is mainly determined by the performance and the amount of binding agent, the green density and firing temperature. When the wheel speed rotation and due to the tangential Cut off wheels  along the aperture itself produced the critical time to reach the tensile strength, the wheel will break, when the wheel rotation speed is called the rupture rate. The actual axis of rotation of the grinding wheel parallel to its axis of rotation through the center of mass offset from a state known as static unbalance wheel. This is usually due to the grinding wheel uneven density, both ends of the plane is not parallel or cylindrical hole concentricity deviation has caused. It will cause the machine vibration, shaft and bearing wear faster, uneven wheel wear and deterioration of the workpiece surface quality. Concrete cutting wheels is the largest amount, the most widely used method of using face when using high-speed rotation, suitable for processing a variety of metal and non-metallic materials.
