Many people think that thinner is better. In fact, this is a prejudice. Thinner does have a certain effect on saving materials, but if it is too thin, it will produce unstable results. We must consider the actual situation. make a judgment.
The saw seam is actually a kind of consumption for the cutting process. The thicker it is, the greater the consumption, but the carbide saw blade itself is a consumable. When choosing the thickness, the cost of the saw blade and the saw seam must be considered. The cost of consumption!
1. Considerations for the selection of thin and thick saw blades
A. Cost of factors to be considered
A very simple case, a thin saw blade, when cutting, the overall loss can be reduced by 200 yuan (assumed), but a thin saw blade is 300 yuan more expensive than a thick saw blade, so you should not choose a thin saw blade. And for the most part, thicker ones are definitely more durable than thinner ones (usually), which also means more cutting knives;
B. The stability of the factors to be considered
The thickness of the cemented carbide saw blade depends on the material of the substrate and the method of the manufacturing process. If the thickness is too high, the production cost is too high, and if it is too thin, it will affect its stability. Generally speaking, the larger the outer diameter of the saw blade, the greater the thickness. Thick, as far as practical, thinking in the direction of corporate interests, the thinner the better without affecting the stability of cutting.
C. The quality of the workpiece to be considered
If the customer requires that the quality of the workpiece is too high, a thinner saw blade should be considered at this time. The thinner the saw blade, the less the friction coefficient, and the higher the quality of the cut workpiece. At this time, it depends on the choice of the enterprise. The cost of the company’s own benefits, or the benefits of considering the actual requirements of customers? Usually, it should be explained to the customer, one is to let the customer increase the cost of cutting processing, and the other is to ask the customer to slightly reduce the quality of cutting (in fact, as long as the thickness and thinness are not too outrageous, the quality of the cut workpiece will not be too different. ), and reasonable requirements are believed to be understood by customers.
2. About the choice of thickness of single-blade saw blade and multi-blade saw blade
When selecting the thickness of the carbide saw blade, the stability of the saw blade cutting process (the grade of the saw blade, the high-grade saw blade is slightly thinner, and the low-grade saw blade is slightly thicker) and the material to be cut should be considered; single-piece saw The thickness of the sheet is usually in the range of 1-4 mm.
There are also some sawing requirements for special effects. At this time, the thickness of the carbide saw blade is uncertain, and multiple saw blades are required, such as slotted saw blades (composed of 2 saw blades + 5 to 9 dart blades, The more dart saw blades, the larger the width of the notch) and the scribing saw blades for precision push table saws (generally composed of 2 saw blades).
Summary: The thickness of the carbide saw blade should be thin or thick. Considering the comprehensive factors, the thin one saves material and the cutting quality is high, but it is unstable. The thick sawing is more stable and the cutting is more durable.
