1. Basic data before selecting saw blade

Machine spindle speed, thickness and material of machined workpiece, outer diameter I size and hole diameter (shaft diameter) of saw.

2. Selection basis

The cutting speed is v = π calculated by the number of spindle revolutions and the outer diameter of the matched saw blade × Outer diameter D × Revolution n / 60 (M / s) the reasonable cutting speed is generally 60-90 M / s. Material cutting speed; Cork 60-90 (M / s), hardwood 50-70 (M / s), particleboard, plywood 60-80 (M / s).

If the cutting speed is too high, the machine tool vibrates and makes a loud noise, 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 feeding speed, the cutting amount per tooth increases, which affects the machining quality and the service life of the saw. Because the relationship between saw blade diameter D and spindle speed n is a power function, it is most economical to reasonably increase the speed and reduce the saw blade diameter in practical application.

3. Quality price ratio

As the saying goes, "cheap goods are not good, good goods are not cheap". It may be true for other goods, but it may not be true for knives and tools; The key is matching. Many factors on the operation site: such as equipment sawing object, quality requirements, personnel quality, etc. Carry out comprehensive evaluation, rationally choose to make the best use of everything, just right, so as to save expenses, reduce costs and participate in industry competition. This depends on the mastery of industry knowledge and the understanding of similar product information.
