Embodiment

[0037] Take the preparation of conventional brazed diamond band saws as an example. The size of the band saw is: width 38mm, substrate thickness 0.8mm, and the total length of the band saw is 1600mm. A segmented diamond abrasive area is arranged on the band saw, and the size of the area is: length × width = 10mm × 5mm. There are 80 sections in the diamond cloth area.

[0038] The specific implementation method is as follows:

[0039] 1. Prepare a thin steel sheet, the material is stainless steel, the thickness of the thin steel sheet is 0.2mm, the length of the sheet is 10mm, and the width is 11mm.

[0040] 2. If figure 1 As shown, the thin steel sheet 1 is equally bent, and the gap in the middle after bending is set to 0.3 mm.

[0041] 3. If figure 2 As shown, superabrasive grains 2 are arranged on the thin steel sheet 1 above. In this embodiment, diamond abrasives are used, and the grain size of the abrasives is 80-100 mesh.

[0042]4. Spread solder on the thin steel ...

Abstract

The invention relates to a brazed super abrasive band saw and a preparation method thereof. The band saw comprises a band saw substrate and a super abrasive, wherein the super abrasive is brazed on a U-shaped sleeve; the U-shaped sleeve is adhered to the edge of the band saw substrate. The preparation method comprises the following steps: bending a thin steel sheet; arranging the abrasive and a solder; feeding in a furnace to braze; adhering and fixing to the outer edge of the band saw substrate in a thermosetting manner and the like. The process and the method for preparing the brazed super abrasive band saw have the characteristics of simple processes, convenience in operation, stable quality and suitability for batch production. The prepared band saw has the advantages of high exposure and high chip removal space of the brazed super abrasive, the strength of the band saw substrate is also guaranteed, and the application problem of a super abrasive brazing technology in the band saw field is perfectly solved. The band saw and the method have a significant effect and economic benefit on promotion of development of the band saw field.

Description

technical field [0001] The invention relates to a brazed superhard abrasive band saw and a preparation method of the band saw, belonging to the field of superhard abrasive tool manufacturing. Background technique [0002] Superabrasive band saws are mostly used for cutting crystal materials such as monocrystalline silicon, polycrystalline silicon, and glass-ceramics, as well as precious materials such as sapphire, and ultra-thin cutting of stone materials such as marble and granite. With the development of technology, some superabrasives Band saws have begun to be used to cut metal materials such as stainless steel and cast iron. Because the superabrasive band saw has the characteristics of narrow kerf, two-dimensional curve cutting, large cutting depth and high cutting precision, it is more and more widely used in the field of material processing. [0003] At present, superabrasive band saws use certain technology to fix superabrasives such as diamond, CBN, PCD (polycrysta...
