Double-headed saws belong to cutting saws, which are found in many aluminum processing industries, especially photovoltaic brackets and door and window brackets. So let's sum up today, what are the specifications of double-headed saw blades in the fields of doors, windows and photovoltaics? Brand and price? How to choose?
First of all, in the door and window industry, aluminum composite and aluminum wood are generally cut. Generally speaking, 450mm and 500mm diameter saw blades are used. The specifications of conventional saw blades are 450×30×4.0× 120 teeth and 500×30×4.4× 120 teeth. Of course, there are many double-headed holes with different diameters on the market, including 40, 32 and 80.
Generally, 80% will be equipped with six screw holes, mainly depending on the smoothness of the surface you cut and what you need. Ordinary high-end saw blades on the market can meet his requirements. Of course, take Kunshan Fengjinrui Tools as an example. It uses 500× 140 teeth. Our company mainly developed 140 teeth for double-headed saws for aluminum doors and windows.
Secondly, let's focus on the photovoltaic bracket. The double-headed saw blade used in his field has many specifications.
450×30×4.0× 120
420×30×3.6× 120
350×30×3.0× 120
Generally speaking, there are six screw holes in the photovoltaic field. Of course, as the thickness of the photovoltaic frame becomes thinner and thinner, many enterprises also start to use thin saw blades, such as 350×30×2.0× 120, 350×30×2.5× 120! Because the thinner the saw blade, the contact surface is needed. The smaller the contact surface of the blade, the smaller the resistance, and there will be no burr. Fengjinrui tool has been studied in this piece for a long time and has its own patent for ultra-thin saw blade.
