What do you think of the specifications and dimensions of saw blades?

For specifications and dimensions, please refer to the following data:

The diameters of standard parts are110mm (4 inches),150mm (6 inches),180mm (7 inches), 200mm (8 inches), 230mm (9 inches) and 20mm (/kloc). 450 mm (18 inch), 500 mm (20 inch), etc. , and the bottom slot saw blade of precision plate saw is mostly designed as 120 mm.

Different cutting materials should choose different saw blades. When selecting a saw blade, it should be selected according to the rotating speed of the machine tool spindle, the thickness and material of the workpiece, the outer diameter and aperture of the cutter.

The sawtooth spacing should be 15-25mm, and the reasonable number of teeth should be selected according to the sawing material. The number of serrations is related to the quality of cutting and the service life of cutting tools. The cutting speed of materials is generally 60-90 m/s. ..

The greater the cutting speed, the greater the vibration, the lower the stability of the saw blade and the shorter the service life. As a tool, there are many factors that affect the service life of the tool, and the choice of saw blade is also very important.

Maintenance of saw blade

1. If the saw blade is not used immediately, it should be laid flat or hung by the inner hole. Other articles or feet shall not be stacked on the flat saw blade, and pay attention to moisture and rust prevention.

2. When the saw blade is no longer sharp and the cutting surface is rough, it must be reground in time. Polishing can't change the original angle and destroy the dynamic balance.

3. The internal diameter correction and positioning hole processing of the saw blade must be carried out by the manufacturer. If it is not handled properly, it will affect the use effect of the product and may be dangerous. In principle, reaming should not exceed the original aperture by 20mm, so as not to affect the stress balance.
