LDX-020A Multi-functional automatic circular saw blade grinder

How to choose a multi-blade saw:

1,Of course, the aperture of the saw blade first depends on the requirements of the machine, because it is a number of pieces installed together, in order to ensure stability, the general design aperture is larger than the aperture of the conventional saw blade, most of the aperture is increased at the same time with a special flange, and the design of the keyway, to facilitate the addition of coolant cooling, more stability. Generally, 110-200MM outer diameter saw blade aperture is between 35-40, 230-300MM outer diameter saw blade aperture is between 40-70, and more than 300MM saw blade is generally less than 50MM.

2,After the multi-blade saw blade welding and grinding is completed, the coating treatment is generally carried out, which is said to extend the service life, in fact, mainly for the appearance of the saw blade, especially the multi-blade saw blade with a scraper, the current welding level, the scraper has very obvious welding marks, so the coating treatment is carried out to ensure the beauty.

3,The multi-blade saw blade is welded with carbide on the saw blade matrix, collectively referred to as the scraper. Scrapers are generally divided into internal scrapers, external scrapers and tooth scrapers, internal scrapers are generally used for hardwood cutting, external scrapers are generally used for wet wood cutting, tooth scrapers are mostly used for trimming or edge sealing saw blades, but can not be generalized. Taking Kobayashi multi-blade saw blade as an example, the number of scrapers under 10 inches is generally 2-4, in order to maximize the role of scrapers, most of the design is external scrapers, the number of 12-inch and above design scrapers is 4-8, the internal scraper and the external scraper are half each, symmetrical design. Multi-blade saw blade with scraper is a trend, foreign companies invented multi-blade saw blade with scraper earlier. When cutting wet wood and hardwood, in order to achieve better cutting effect, reduce the saw blade paste tooth burning, increase the mechanical chip removal capacity, reduce the number of grinding, increase the durability. However, with a scraper multi-blade saw blade grinding is difficult, general equipment can not be grinding, the price is relatively high.
