What is the factors of affecting the diamond saw blade life?

(1) Diamond Blade Rotation Speed: in practice, the line speed diamond saw blades by equipment conditions, saw the quality and nature of the stone before cutting restrictions. From the optimum blade life and cutting efficiency, it should be selected depending on the nature of the stone saw blade speed. Sawing granite, the blade speed at 25m ~ 35m / s within the selected range. For high quartz content and difficult cutting granite, remove the blade speed limit is appropriate.  cubic boron nitride tiles in the production, the use of smaller diameter diamond saw blade, the line speed can reach 35m / s.

(2) Cutting Depth: diamond cutting depth is related to wear, effective cutting, saw cutting force conditions and the nature of the important parameters of stone. Generally speaking, when the line Polycrystalline diamond  saw blade is high, should be selected for cutting of small depth, from the current technology, the cutting depth of the diamond can choose between 1mm ~ 10mm. Usually with a large diameter saw blade cutting granite blocks, the cutting depth can be controlled within 1mm ~ 2mm between the feed rate should be reduced at the same time. When the line speed diamond saw blade is large, a large cutting depth should be selected. But in performance and tool  strength  saw the extent permitted, should try to take a greater depth of cut  synthetic diamond  to improve cutting efficiency. When the machined surface when requested, should be used small depth of cut.

(3) Feed speed: Cutting feedrate incurs stone feed rate. Its size sawing rate impact, the force and the cutting blade heat dissipation area. Its value should be based on the nature of the selected cutting stone. Generally speaking, sawing softer stone, such as marble, may be appropriate to increase the feed speed, if the feed rate is too low, more conducive to high cutting rates. Sawing fine structure, relatively homogeneous granite, may be appropriate to increase the feed speed, feed rate is too low if the diamond blade easily be polished. But sawing UNEVEN coarse granite structure, should reduce feed speed, otherwise it will cause the blade vibration and reduce fragmentation leading diamond cutting rates. Granite cutting feed rate is generally 9m ~ 12m/min within the selected range.
