Multi-saw introduction edit multi-saw blade after more than a combination of machining, and is a single-chip saw blade work, saw a single job is generally not very high, even if the quality is not much affected slightly worse; The multi-saw is not the same, for the blade is relatively high, provided that the use of multi-chip saws generally require more to save wood, small kerf, saw Pu, high quality finish. Blade hole, generally divided into the vents and silencer holes. Vents - blade due to work at high speed conditions, saw the body can easily lead to distortion due to heat; silencer holes - saw reduce noise generated in the work. Usually burning blade reasons are the following cases: 1. the blade overall heat dissipation is not good. 2. The blade teeth too much. Teeth, the greater the resistance, the blade burn easily. 3. Saw poor chip. Sawdust if not easily removed from the device will cause the local temperature is too high, it tends to burn pieces, so be sure to choose the right saw. Too many impurities or poor quality 4. Materials. For example, if the saw is particleboard, and particleboard too coarse, excessive impurities, too much resistance, will burn sheet. Development of more than two saws edit multi-chip saw the development process, and since 2000, woodworking machinery into the fast lane of reform, multi-chip sawing wood processing low-end products, a very small space of reform, it has been in the kind of The most simple style, poor working conditions, workers have been working in dust pollution, I plant after several exploration and production of several multi-saw variability products, coupled with the dust removal equipment, plus a protective cover, effectively change the working environment
