About Multi - blade saw blade 2

1. Aperture of multi-blade saw blade:

Multi saw saw blade aperture, of course, the first to see the requirements of the machine, because it is installed together, in order to ensure stability, the general design aperture is larger than the conventional saw blade aperture, most of the increase in aperture at the same time with special flange, and design keyway, to facilitate the addition of coolant cooling, more stability. General 110-200mm outer diameter saw blade aperture between 35-40, 230-300mm outer diameter saw blade aperture between 40-70, 300MM above the saw blade is generally less than 50MM.

2. Tooth shape of multi-blade saw blade:

The tooth shape of multi-blade saw blade is mainly made of left and right alternating teeth, and a few small diameter saw blades are also designed as flat teeth.

3. Multi-slice saw blade coating:

After finishing the welding and grinding of multi-slice saw blade, coating treatment is generally carried out, which is said to prolong the service life. In fact, it is mainly for the appearance of the saw blade, especially the multi-slice saw blade with scraper. At the current welding level, there are very obvious welding traces at the scraper, so coating treatment is carried out to protect the appearance.

4. Multi-blade saw blade with scraper:

Multi - blade saw blade in the saw blade substrate welding carbide, collectively known as the scraper.

Scraper is generally divided into internal scraper, external scraper and tooth scraper, internal scraper is generally used for hardwood cutting, external scraper is generally used for wet wood cutting, tooth scraper is mostly used for trimming or edge sealing saw blade, but can not be generalized.

To the small forest saw saw blade for example, the general design of the scraper below 10 inches number of 2-4, in order to let the scraper play the largest role, most of the design of the scraper, 12 inches and above the design of the scraper number of 4-8, inside and outside the scraper half, symmetrical design. Multi-blade saw blade with scraper is a trend, the foreign company invented the multi-blade saw blade with scraper earlier.

When cutting wet wood and hardwood, in order to achieve better cutting effect, reduce blade paste tooth burning, increase the chip removal ability of machinery, reduce the number of grinding, increase durability.

However, it is very difficult to repair and grind the scraper with a blade saw. General equipment can not repair and grind, and the price is relatively high.
