Tooth shape of multi-blade saw blade
The tooth shape of multi-blade saw blade is generally left and right alternating teeth, and a few small diameter saw blades are also designed as flat teeth.
Coating of multi-blade saw blade
After the multi-blade saw blade is welded and polished, it is generally coated. It is said that the service life can be extended. In fact, it is mainly for the beauty of the saw blade, especially the multi-blade saw blade with a scraper. At the current welding level, there are very obvious welding marks at the scraper, so the coating treatment is carried out to ensure the beauty.
Multi-blade saw blade with scraper
The multi-blade saw blade is welded with cemented carbide on the base of the saw blade, which is collectively referred to as the scraper. The scraper is generally divided into internal scraper, external scraper and tooth scraper. The internal scraper is generally used for the cutting of hardwood, the external scraper is generally used for the cutting of wet wood, and the tooth scraper is mostly used for trimming or edge sealing saw blade, but it cannot be generalized. Take Xiaolin's multi-blade saw blade as an example. Generally, the number of designed scrapers under 10 inches is 2-4. In order to make the scrapers play a larger role, most of them are designed as external scrapers. The number of designed scrapers 12 inches and above is 4-8, and the internal and external scrapers are each half, symmetrical design. Multi-blade saw blade with scraper is a trend. Foreign companies invented the multi-blade saw blade with scraper earlier. When cutting wet wood and hardwood, in order to achieve better cutting effect, reduce the tooth burning of the saw blade, increase the chip removal capacity of the machine, reduce the number of grinding, and increase the durability. However, it is very difficult to grind the scraper with a scraper and a multi-piece saw, and the general equipment cannot be polished, and the price is relatively high.
