The thickness of the carbide saw blade (commonly known as the kerf), many people think that the thinner the better, in fact, this is a kind of prejudice, the thinner is indeed a certain effect for saving materials, 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 more expensive, but the carbide saw blade itself is a kind of consumable. When choosing the thickness, the cost and sawing of the saw blade must be considered. Cost of consumption!
First, the thin and thick selection considerations of the saw blade
A, the cost of consideration
A very simple case, a thin saw blade, the overall wear and tear can be reduced by 200 yuan (assumed), but the thin saw blade is 300 yuan more expensive than the thick saw blade, then you should not choose thin And most of the time, thicker, certainly more durable than thinner (usually), which means more cuts;
B. Stability of considerations
The thickness of the carbide saw blade depends on the material of the substrate and the manufacturing process. The excessively thick production cost is too high, and the too thin will affect its stability. Generally speaking, the larger the outer diameter of the saw blade, the greater the thickness. Thick, as far as the actual situation is concerned, considering the interests of the company, the thinner the better, without affecting the stability of the cut.
C. Consideration of the quality of the workpiece
If the customer requires the quality of the workpiece to be too high, it is necessary to consider a thinner saw blade. The thinner the friction, the less the friction system will be. The higher the quality of the cut off workpiece, the more the choice of the enterprise depends on the choice. The cost of the enterprise's own interests, or the benefits of the actual requirements of the customer? Under normal circumstances, it should be explained to the customer, first, to increase the cost of cutting the processing, and second, to require the customer to slightly reduce the quality of the cutting (in fact, thick and thin, as long as it is not too outrageous, the quality of the cut off the workpiece will not be too different. ), reasonable requirements believe that customers will understand.
Second, the choice of single-chip saw blade and multi-blade saw blade thickness
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 with a slightly thinner, the lower-grade saw blade is slightly thicker) and the material to be cut should be considered; the single-piece saw The thickness of the sheet is usually between 1-4 mm.
There are also some special effects of sawing requirements. At this time, the thickness of the carbide saw blade is an uncertain one. It requires a multi-blade saw blade, such as a slotted saw blade (consisting of 2 saw blades + 5 to 9 darts). The more dart saw blades, the wider the range of their slots, and the scribe saw blades for precision table saws (generally composed of 2 saw blades).
Summary: The thickness of the carbide saw blade should be thin or thick. Due to the comprehensive factors, the thin material and cutting quality are high, but unstable, the thick sawing is more stable and the cutting is more durable.
