How to choose a saw blade correctly?

1. Select basic data before the saw blade

The thickness of the workpiece and the outer diameter I size and aperture (axis diameter) of the material saw

2. Selection basis

The cutting speed is v=π, and the reasonable cutting speed is calculated from the spindle rotation number and the matching saw blade outer diameter × outer diameter D × revolution number n/60 (M/s). The material cutting speed is generally 60-90 M/s; soft wood 60-90 (M/s), hardwood 50-70 (M/s) particle board plywood 60-80 (M/s)

If the cutting speed is too high, the vibration noise of the machine tool is high, the stability of the saw blade is reduced, the processing quality is reduced, the cutting speed is too small, and the production efficiency is reduced. At the same feed speed, the cutting amount per tooth increases, which affects the processing quality and service life of the saw blade. Since the relationship between the saw blade diameter D and the spindle speed n is a power function, in practical applications, it is most economical to reasonably increase the speed and reduce the saw blade diameter.

3. Quality-price ratio

'Bags are not good, good goods are not cheap' Other products may be like this, but knives and tools may not be like this; the key is to match the work site with multiple factors: such as the quality of equipment sawing objects requires personnel quality, etc., conduct comprehensive evaluation, make reasonable choices, use the best products, and be just right to save costs and reduce costs. Participate in industry competition. This depends on the mastery of industry knowledge and the understanding of similar product information.
