Diamond Saw Blade cutting the amount of

In the stone processing, stone processing cutting costs account for about 50% of the total cost. At present, China's stone business is quite common to use diamond circular saws for the cutting device. According to statistics, the average per sawing 1m. Granite diamond segment consumes about 3-3.8 million, the power consumption of about 10 ~ 12kW.h, to China's annual use of diamond circular saw stone cutting 150 million m2 per  diamond grinding wheel annum gross consumption of diamond saw blades more than 500 million yuan, the total energy consumption by about 2 billion kw.h, thus optimizing the amount of diamond saw blades for cutting, reducing energy consumption, saw cutting consumption and improve the efficiency of far-reaching economic and social significance.
Diamond circular saw cutting costs affecting factors include stone composition, structure, physical and mechanical properties, equipment, technical performance, the blade cutting the amount of process performance and selection and other factors. Several factors in this regulation is only cutting the amount of artificial optional. Therefore, improving the stone sawing process is to reduce energy consumption, consumption and improve cutting efficiency saws to reduce the effective cost cutting measures.Grinding damage: the force effects and temperature than the response, after a period of use of the blade tend to produce wear damage. Grinding damage in  dry cut blades the form of mainly the following: abrasive wear, local crushing, a large area of ​​broken off, binders direction along the cutting speed of the mechanical abrasions. Abrasive: Diamond particles and constant friction formula pieces, into a flat edge passivation, loss cutting, increasing friction. Heat causes the cutting surface of the diamond particles graphite sheet, the hardness greatly reduced, increased wear: the surface of the diamond particles exposed to alternating thermal stresses, and also the cutting under alternating stress, fatigue cracks will be partially broken, revealing a sharp new edge, is an ideal wear pattern; large area broken: diamond particles in the Leads to withstand shock loads, the concrete cutting blade  more prominent grain and grain prematurely consumed; shedding: the diamond cutting force alternating binding agent particles are constantly being generated shaking loose. Meanwhile, the cutting process of the binding agent itself wear and cutting heat to soften the binding agent. This makes the gripping force decreased binding agent, when the particle is greater than the cutting force on the gripping force, the diamond particles will fall off. No matter what kind of wear and tear with the diamond particles to withstand load and temperature are closely related. Both of which are determined by Cheng cutting process and cooling lubrication conditions.
