In theory, we hope that the thinner the saw blade is, the better the thickness of the saw blade. The saw gap is actually a kind of consumption. The material of the alloy saw blade base and the process of manufacturing the saw blade determine the thickness of the saw blade. The thickness is too thin. The multi-blade saw blade is easy to shake when working, affecting the cutting effect. Taking the multi-blade saw blade as an example, the thickness of 110-150MM outer diameter can be 1.2-1.4MM, and the thickness of 205-230MM outer diameter saw blade is about 1.6-1.8MM, It is only suitable for cutting softwood with small density. When selecting multiple saw blade thickness, the stability of the saw blade and the sawing material should be considered.
At present, in order to reduce consumption, some companies start to produce single-sided convex or double-sided convex multi-blade saw blades, that is, thicker on both sides of the middle hole and thinner on the inside of the alloy, and then weld the teeth to ensure the cutting thickness and achieve the effect of material saving, and the cutting depth is not more than 40MM. Some equipment are designed to have the effect of direct trimming. It is necessary to install a multi-piece saw blade. The trimming saw blade is generally thickened to ensure the smoothness of edge cutting.
The quality of the multi-blade saw blade plays a vital role, because we all know that the adjustment and rotation of the multi-blade saw blade of the woodworking machinery not only transfers the cutting force, but also maintains the stability of the work. The excellent multi-blade saw blade not only has the static geometric size and accuracy, but also has the particularly good dynamic characteristics. After multiple grinding, the service life is long, and the welding quality of the cemented carbide is also very important, When the multi-blade saw blade is continuously cut, the temperature of the saw blade will rise rapidly. In this case, the high-quality saw blade can maintain a high standard of accuracy, while the low-quality saw blade will warp the saw blade, so that the saw blade can bear greater cutting force, and the cutting accuracy of wood is very high.
