The choice of aluminum alloy blades

(A) the choice of diameter
Saw blade diameter with the use of cutting equipment and cutting the workpiece thickness. Saw blade diameter is small, the cutting speed is relatively low; Saw blade diameter and sawing  granite core bits equipment requirements for the necessary high, while the cutting efficiency is high. Depending on the diameter of the blade circular sawing machine model selection with a diameter matching blades.
Standard parts diameter: 180MM (7 inch), 205MM (8 inches), 255MM (10-inch), 305MM (12-inch), 355MM (14-inch), 405MM (16-inch), 455MM (18-inch), 505MM ( 20 inch), etc.
(B) Select the number of teeth
Serrated teeth, in general, the cutting edge per unit time, the more the better cutting performance. But not too much teeth should be selected according to the material thickness sawing a reasonable number of teeth.
Serrated too close, teeth of the chip becomes smaller, easy to cause the blade fever; another jagged too, when the  step pads feed rate mis-match, then cut each tooth small amounts, will exacerbate friction with the workpiece edge, edge effects life. Tooth pitch usually about 15-25mm.
(C) the thickness options
The thickness of the blade from the saw blade in theory, we hope that the thinner the better, is actually a kerf consumption.
Matrix alloy saw blade materials and manufacturing processes determines the thickness of the saw blade, the thickness is too thin, the work is easy to shake the blade, the impact effect of cutting.
Select from the blade when the blade thickness of job stability and sawing material to consider. Some special-purpose materials required thickness is given, it should be according to the  diamond blade requirements of workpiece machining equipment and choose the right thickness.
(D) the choice of aperture
Aperture is a relatively simple parameters, equipment requirements are mainly based on choice, but in order to maintain the stability of the blade, 455MM best selection of aperture blades than larger device. Design standards currently imported parts aperture, 205MM to 405MM mostly 25.4MM Kong, more than 455 mostly 30 apertures, some of the imported equipment has 15.875MM hole, multi-chip sawing machine aperture is relatively complex, with keyway to ensure the stability of the multi- . Regardless of pore size, can be transformed through the lathe or EDM, lathes car washer can be set in a large aperture, EDM can reaming necessary requirements for the device.
