Problems solved by technology

[0003] Marble belongs to the hard and brittle plate, which is divided into several grades such as low hardness, medium hardness and high hardness. Currently, it is used in the precision cutting of high hardness marble, but the cutting effect is generally poor, the cutting efficiency is difficult to improve, and there are cutting collapses. The edge collapses, the cutting speed is slow and the cutting life is insufficient. At the same time, its versatility is also limited by the hardness of the marble. It is generally no problem when cutting low-hardness marble, but it is no longer suitable for cutting medium-hard and high-hard marble.

Embodiment 1

[0047] Embodiment 1-low-hard marble: the cutting piece is cut and edged, and then installed on an infrared automatic bridge cutting machine to cut low-hard agarwood beige marble with a length of 1.95m and a thickness of 30mm, and the average cutting feed rate of the test is 7.09m / min, there is no phenomenon of edge collapse and bottom collapse, the noise is low, and the edge appearance of the cut agarwood beige marble is excellent.

Embodiment 2

[0048] Example 2-medium-hard marble: the cutting piece is cut and edged, then installed on an infrared automatic bridge cutter, and cut into a medium-hard white magnolia marble with a length of 3.1m and a thickness of 30mm, and the average feed rate of the test is 5.34m / min, there is no phenomenon of edge collapse and bottom collapse, and the edge appearance of the cut white magnolia marble is excellent.

Embodiment 3

[0049] Example 3-medium-hard marble: the cutting piece is cut and edged, then installed on an infrared automatic bridge cutter, and cut into a medium-hard silver shadow gray marble with a length of 2.0m and a thickness of 18mm, and the average feed rate of the test is 5.60 m / min, there is no phenomenon of edge collapse and bottom collapse, the noise is low, and the edge appearance of the cut silver shadow gray marble is excellent.

Abstract

The invention discloses a diamond cutting blade special for fine cutting of marble by an infrared bridge cutting machine and a manufacturing method thereof. The cutting blade comprises a high-continuity fan-shaped segment and a matrix. The manufacturing method comprises a pre-alloyed powder formula, diamond grain size distribution and concentration, heating sintering process parameters and a welding process. A hot pressing sintering technology is used for manufacturing the fan-shaped segment with the customized size of the cutting blade, a high-frequency welding technology is adopted for welding the fan-shaped segment and the matrix, the welded cutting blade is polished, ground and edged and then used for cutting marble by the infrared bridge cutting machine, the cut marble is various in category, the universality is very excellent, edge breakage and bottom breakage are avoided during cutting, and the diamond cutting blade is small in noise, very good in cutting effect, long in cutting service life and high in plate outturn percentage, and is an edge tool for fine cutting of marble.

Description

technical field [0001] The invention relates to the technical field of superhard material tool products, in particular to a diamond cutting disc specially used for finely cutting marble by an infrared bridge cutting machine and a manufacturing method thereof. Background technique [0002] Marble is widely used in home improvement flooring and other fields because of its various types and patterns. It is a natural stone. Different types of marble have different physical properties, hardness, strength and toughness, and different components. There are great differences in precision cutting, and the cutting effect has become the threshold for whether the cutting wheel can work. Only when the cutting effect is good can the comparison of cutting efficiency and cutting life be carried out. [0003] Marble belongs to the hard and brittle plate, which is divided into several grades such as low hardness, medium hardness and high hardness. Currently, it is used in the precision cuttin...
