Sandwich type frame saw tool bit and manufacturing method thereof

Abstract

The invention provides a sandwich type frame saw tool bit and a manufacturing method thereof. The tool bit can keep good cutting performance all the time in the use process, and therefore the machining quality and the service life are ensured. The sandwich type frame saw tool bit is provided with a cutting part which is made of diamond powder and functional metal powder. The cutting part comprises at least two work layers, a transition layer is arranged between every two adjacent work layers, and the two sides of the sandwich type frame saw tool bit are the corresponding work layers. The granularity of the diamond powder in the work layers is smaller than that of the diamond powder in the transition layers; the concentration of the diamond powder in the work layers is larger than that of the diamond powder in the transition layers; and the hardness of alloy matrixes in the work layers is larger than that of alloy matrixes in the transition layers. By means of the manufacturing method for the tool bit, the components and the shapes of the work layers and the transition layers can be accurately controlled, and therefore sharpness of the tool bit is maintained all the time in the use process, the guidance property of the tool bit is improved, the cutting quality is improved, and the service life of the tool bit is prolonged.

Description

technical field [0001] The invention relates to a cutter for cutting or grinding stone, in particular to a cutter head of a gang saw and a manufacturing method thereof. Background technique [0002] Gang saw is currently one of the most commonly used and most advanced tools in cutting stone blocks. It has high processing efficiency, high board yield, high cutting precision, good board surface flatness, high flexibility in board size, and saves water and electricity. Features. The traditional gang saw blade is made of uniform material, which will be gradually worn during use, the cross-section becomes arc-shaped, and the sides of the blade become thinner, which will cause the cutting force to disperse, which will not only increase the load of the gang saw , and will affect the quality of processing. Contents of the invention [0003] The object of the present invention is to provide a sandwich type gang saw cutter head and its manufacturing method. This kind of cutter hea...
