concrete cutting discs Cut pieces belonging wheel,

Cut pieces belonging wheel, abrasive and binder resins made ​​for ordinary steel, stainless steel sheet metal and nonmetal materials.Made of glass fiber reinforced resin material cutting disc for stone combined with high tensile, impact and flexural strength, widely used in ordinary steel, stainless steel and non-metallic materials production, the excellent material, exquisite craftsmanship ensures that different materials high cutting efficiency of the workpiece and the best economic results.Cut pieces according to the material is divided into fiber resin cutting discs and diamond cutting discs. 
1 resin cutting discs are resin binder, combined with a variety of materials, for alloy steel, stainless steel and other difficult cutting material, cutting performance is particularly significant. cutting discs Dry cutting ﹑ wet two ways to make a more stable cutting accuracy while cutting sheet material and hardness of choice, can greatly improve your cutting efficiency, saving you the cost of production. 
2 diamond cutting disc is a cutting tool that is widely used in the processing of stone, concrete, precast panels, new and old road, ceramics and other brittle materials, diamond cutting discs mainly consists of two parts; .. substrate and the substrate is glued head Results of the tip portion of the main support, while the head is cut from the part during use, and, in use, the tip will be consumed continuously while the substrate is not, the blade is able to cut the role played because it contains diamond, diamond as the most rigid material, which is cut in the head of the object to inox flap disc be processed friction while diamond particles [1] by the metal particles inside the wrapped head.

concrete cutting blades Performance Analysis

⑴ ceramic material because of its excellent properties such as high hardness, high wear resistance, high temperature resistance, corrosion resistance, high stiffness til granite cutting wheels to weight ratio concrete cutting blades, density and strong chemical inertness to the scientific and industrial increasingly widespread application. 
⑵ widely used high-temperature superconducting single crystal film substrate, laser parts, the use of these new materials, due to the brittle, prone to cracking during processing, often accompanied by a large number of processing problems. 
⑶ Diamond is the hardest material in nature, with a grinding wheel which is made to solve the problem of processing of glass, ceramic material of high hardness. For the development of flap wheel new engineering ceramics such as silicon nitride, while grinding with a resin or a metal-bonded diamond wheel, the binding agent is prone to insufficient gripping force abrasive, wear increases; toughness and binding agent is too large, the grinding wheel pores less grinding force declined after blunt grinding wheel dressing is difficult, so that the entire grinding process more difficult. 
⑷ quality vitrified ceramic or vitreous, binders rigid, high temperature, suitable for finishing grinding, so that the knife does not produce the phenomenon. Vitrified abrasive and strong adhesion to the edges and corners to maintain good performance, can be precision grinding. 
⑸ vitrified diamond grinding wheel in the manufacturing process can be adjusted on the hardness and porosity, help to improve grinding performance through reasonable proportion and cutting grinding discs production control, no distortion, it also makes the reasons for the high precision grinding wheel .

concrete cutting discs When vitrified diamond grinding wheel, has the following advantages;

Advantage 
1) high grinding efficiency; 
2) with high wear resistance: the wheel cutting disc for inox wear resistance, low abrasive consumption, especially when grinding very hard brittle workpiece obvious; 
3) small grinding force, grinding temperature is low; 
4) high-precision grinding of workpieces, good surface quality, the shape of the workpiece to maintain good. 
So vitrified diamond grinding wheel in ceramics and other special material, with more and more obvious advantages, has good prospects in the development of the diamond wheel. Is considered to be high speed, high efficiency, high-performance high-precision grinding wheels, grinding low cost, low environmental til granite cutting wheels pollution, with more and more widely used, is the recent world competing research and development of grinding tools hotspot.

concrete cutting discs Relationship with the modern industry

With the development of technology, high strength, high wear resistance, high hardness, high temperature, light emerging new materials, but also to the high quality machining, concrete cutting wheels high precision, high efficiency, automation direction continues to develop, resin bond diamond wheel are increasingly unable to meet the above requirements, vitrified diamond grinding wheel emergence of this new solution to the above problem concrete cutting discs
Vitrified diamond grinding wheel with high strength, heat resistance, cutting sharp, high grinding efficiency, grinding process is not easy fever and congestion, a small amount of thermal expansion, in order to control the machining accuracy. Compared with resin bonded grinding wheel, he solved the low life resin diamond grinding wheel, low grinding efficiency, grinding itself variability during grinding problems. It is these advantages ceramic cutting disc bond diamond wheel grinding wheel based on its appearance immediately developed widely used in wafer (semiconductor wafers and solar wafers), PDC, polycrystalline diamond, diamond tools, CBN , machining tungsten steel (alloy), new engineering structural ceramics, precious stones, crystal, rare earth materials (magnetic) high hard and brittle material, and achieved good economic benefits. 
Development of domestic ceramic diamond grinding wheel: There are some companies have noticed the advantages of vitrified diamond grinding wheel, began to bond diamond wheel ceramics research and development, production technology matures. More and more ceramics, gems and machining manufacturer of ceramic diamond wheel to start the trial to further reduce production costs .... vitrified diamond grinding wheel play in the future granite cutting disc more and more important role in industrial production.
