Many people have a very limited understanding of TCT circular saw blades. Today we will talk about the choice of aperture for TCT circular saw blades .

Aperture is a relatively simple parameter, which is mainly selected according to the requirements of the equipment. However, to maintain the stability of the saw blade, it is best to choose a larger aperture for the saw blade above 250mm. At present, the diameters of standard parts designed in China are mostly 20MM holes for 120MM and below, 25.4MM holes for 120-230MM, 30 holes for more than 250, and some imported equipment also have 15.875MM holes. The mechanical diameter of multi-blade saws is relatively complicated. , There are many key ways to ensure stability. Regardless of the size of the hole, it can be modified by a lathe or a wire cutting machine. The lathe can be turned into a gasket with a large hole, 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 profile, the angle, the aperture, etc. are combined into the whole of the carbide saw blade. It is necessary to select and match reasonably to better exert its advantages.
