The purchase and correct use of carbide circular saw blades

1. Key data:

① Spindle speed of the machine,

② Thickness and material of the workpiece,

③ Outer diameter and aperture (shaft diameter) of the saw blade.

2. Selection criteria:

The cutting speed can be calculated based on the spindle speed and the outer diameter of the intended saw blade. The formula for cutting speed is V=π×outer diameter D×speed N/60 (m/s). The reasonable cutting speed is generally between 60-90 m/s. If the cutting speed is too high, it will increase machine tool vibration, noise, and reduce the stability and processing quality of the saw blade. If the cutting speed is too low, it will reduce production efficiency. For the same feed speed, increasing the cutting amount per tooth will affect the processing quality and the lifespan of the saw blade. Due to the power function relationship between the saw blade diameter D and the spindle speed N, in practical applications, it is possible to increase the speed appropriately and reduce the saw blade diameter to achieve the optimal economic efficiency.

3. Quality-price ratio:

There is a saying, "You get what you pay for." This saying may be true for other products, but not necessarily for cutting tools. The key lies in compatibility. It is necessary to evaluate various factors in the work site, such as the cutting object of the equipment, quality requirements, and personnel qualifications, and rationally choose products that are cost-effective and suitable to save expenses and reduce costs to compete in the industry. This requires knowledge in the field and understanding of similar product information.
