Carbide circular saw blade purchase and correct use
Basic data: 1 machine spindle speed, 2 machined workpiece thickness and material, 3 blade saw outer diameter size and aperture (shaft diameter)2.
2. Selection basis: Calculated by the spindle rotation number and the outer diameter of the mating saw blade. Cutting speed: V=π×outer diameter D×number of revolutions N/60 (m/s) The reasonable cutting speed is generally 60-90 m/ second,
The cutting speed is too large, the machine tool has large vibration, large noise, reduced saw blade stability, reduced processing quality, too small cutting speed, and reduced production efficiency. The same feed speed, the amount of cutting per tooth increases, affecting the quality of the machining and the life of the saw. Because the saw blade diameter D and the spindle rotational speed N are power functions, in practical applications, it is most economical to increase the rotational speed reasonably and reduce the saw blade diameter.
3, the price-to-price ratio: the saying goes: "cheap is not good, good goods are not cheap", may be correct for other goods, but for the tooling tools, I am afraid not to be the same; the key is matching. Many factors on the job site: such as equipment sawing objects, quality requirements, personnel quality, etc. Conduct a comprehensive assessment, rationally choose the best use of materials, just right, to save money, reduce costs, and participate in industry competition. This depends on mastery of professional knowledge and understanding of similar product information.
In order to make the saw blade perform its best performance, it must be used in strict accordance with the specifications;
