The thickness of carbide saw blades (commonly known as saw seams), many people think that the thinner the better, in fact, this is a prejudice, the thinner does have a certain effect on the material saving, but if it is too thin, it will produce Unstable results, we must judge according to the actual situation. Saw seam is actually a kind of consumption for cutting processing, the thicker the bigger the consumption, but the carbide saw blade itself is a consumable. When choosing the thickness, you must consider the cost of the saw blade and the saw seam The cost of consumption!
First, the considerations for the choice of thin and thick saw blades
1. Cost considerations
A very simple case, a thin blade, when cutting, the overall wear and tear can be reduced by 200 yuan (assuming), but a thin blade is 300 yuan more expensive than a thick blade, then you should not choose thin And most of the time, thicker ones are definitely more durable than thinner ones (usually), which also means more cutting blades.
2. Stability of consideration factors
The thickness of the carbide saw blade depends on the material of the substrate and the manufacturing process. Too thick production cost is too high, too thin will affect its stability. Generally speaking, the larger the outer diameter of the saw blade, the more the thickness Thick, in terms of reality, thinking in the direction of corporate interests, without affecting the stability of the cut, the thinner the better.
3. The quality of the workpiece considering the factors
If the customer requires that the quality of the workpiece is too high, then a thinner blade should be considered. The thinner the friction, the less the degree of friction, and the higher the quality of the cut workpiece. At this time, it depends on the choice of the enterprise. The cost of the enterprise's own benefits, or the benefit of the actual requirements of the customer? Ordinarily, it should be explained to the customer. First, let the customer increase the cost of cutting and processing, and second, ask the customer to slightly reduce the quality of the cutting (in fact, thick and thin, as long as it is not Too ridiculous, the quality of the cut-out parts will not be too different), reasonable requests believe that customers will understand.
Second, about the choice of single-blade saw blade and multi-blade saw blade thickness
When choosing the thickness of the carbide saw blade, the stability of the cutting process of the saw blade (the grade of the saw blade, the thinner for high-end saw blades and the thicker for low-end saw blades) and the materials to be cut should be considered; single-piece saws The thickness of the sheet usually ranges between 1-4 mm. There are also some special requirements for sawing. At this time, the thickness of the carbide saw blade is an uncertain one. Multi-blade saw blades are required, such as slotted saw blades (composed of 2 saw blades + 5 to 9 darts blades). , The more dart saw blades, the greater the width of the slot width) and the scoring saw blade for precision sliding table saws (generally composed of 2 saw blades).
Summary: Whether the thickness of the carbide saw blade should be thin or thick, due to comprehensive factors, thin material saving, high cutting quality, but unstable, thick saw cutting is more stable and cutting is more durable.
