Saw Blade Aperture Selection

The aperture is a relatively simple parameter, which is mainly selected according to the requirements of the equipment, but in order to maintain the stability of the saw blade, it is best to use equipment with a larger aperture for saw blades above 250MM. The aperture of the standard parts designed in China, the diameter of 120MM and below is mostly 20MM holes, 120-230MM is mostly 25.4MM holes, and more than 250 is mostly 30mm holes. Some imported equipment also has 15.875MM holes. The mechanical aperture of multi-blade saws is relatively complicated. There are many keyways to ensure stability. Regardless of the size of the aperture, it can be modified by a lathe or a wire cutting machine. The lathe can turn the gasket into a large aperture, and the wire cutting machine can expand the hole to meet the requirements of the equipment. A series of parameters such as the type of alloy cutter head, the material of the substrate, the diameter, the number of teeth, the thickness, the tooth shape, the angle, and the aperture are combined into a whole hard alloy saw blade. It must be reasonably selected and matched to give full play to its advantages.
