Problems solved by technology

[0002] There are many materials used in the production of conventional diamond saw blades, and the diamonds are randomly distributed on the saw blades, resulting in the inability of the diamonds to fully perform their functions. When the conventional saw blades are working, they have large cutting resistance, high energy consumption, low efficiency, and poor precision, which limits The normal use of diamond saw blades also limits the scope of use of diamond saw blades and hinders the development of cutting technology

Abstract

The invention discloses an ultrathin layer composite saw blade containing diamonds in radial oriented distribution and a manufacturing process therefore. The ultrathin layer composite saw blade is formed by stacking a plurality of saw blade segments, wherein the saw blade segments are formed by compounding working layer ultrathin sheets with the thickness of 0.1-1.0 mm and isolation layer ultrathin sheets with the thickness of 0. 1-1.0 mm; and the segment working layer ultra-thin sheet matrix takes metal powder and the diamond as raw materials, and the segment isolation layer ultrathin sheets take graphite powder, silicon carbide powder, alumina powder and ceramic powder as raw materials. The manufacturing process comprises the following steps that the diamond particles are buried into preset positions of the matrix in the radial oriented distribution structure during cold-pressing forming of the working layer ultrathin sheets; the materials are vibrated by adopting ultrasonic waves or other high-frequency vibration platforms in the charging process so that the thickness of the materials can be ensured to be uniform and consistent, and the saw blade segments are manufactured through a hot-pressing sintering process; and the saw blade segments are welded on a saw blade base body with the diameter of 100-2500 mm through a high-frequency or laser welding technology. The ultrathin layer composite saw blade is high in working efficiency, long in service life, low in energy consumption, and beneficial for saving resources and energy.
