Embodiment 1
[0061] Such as figure 1 As shown in , a bending-resistant multi-strand steel wire rope 1 with a diameter of φ1 mm is degreased with acetone, and the high-temperature-resistant inorganic adhesive is applied to the steel wire rope at certain intervals. After drying and curing, an isolation masking area 2 is formed.
[0062] Take the metal brazing material, add organic glue and make a paste.
[0063] Such as figure 2 As shown in , use paste metal brazing material to smear the spaced part 3 on the multi-strand steel wire rope 1, then sprinkle diamond particles 4, spray a layer of paste metal brazing material after solidification, and then sprinkle diamond particles 4. Spray a layer of paste metal brazing material after solidification, put it into a vacuum brazing sintering furnace after drying, raise the temperature to 950°C, then cool it and take it out to obtain a semi-finished diamond wire saw. Such as image 3 with Figure 4 As shown in , the semi-finished wire saw is san...
Embodiment 2
[0066] Such as Image 6 As shown in , take a single thin steel wire 6 with a diameter of φ0.8mm, dip it in high temperature resistant inorganic glue and take it out. The release layer 7.
[0067] Take diamond abrasive grains and metal brazing material, add organic glue and make paste.
[0068] Such as Figure 7 As shown in , the release layer 7 is coated or cold-pressed with a diamond-containing paste 8 at intervals, and then the single-strand steel wire 6 coated with the paste 8 is put into a vacuum brazing furnace for sintering. After drying, place it in a vacuum brazing furnace and heat it up to 950°C before sintering. After cooling, exit the single-strand steel wire at the center to obtain a self-supporting (that is, without a metal matrix) ring-shaped diamond brazing layer (paste 8 obtained after sintering), that is, as Figure 8 The diamond bead 40 shown in. Then these beads 40 are strung on the φ1mm bending-resistant multi-strand steel wire rope 1 at intervals, and...
Embodiment 3
[0071] Take diamond abrasive grains and metal brazing material, add organic glue and make paste.
[0072] Take a steel pipe with a diameter of 0.5 mm to 2 mm, coat or cold press the paste on it, and then put it into a vacuum brazing furnace for sintering. After being released from the furnace, the above-mentioned steel pipe is cut into small sections with a length of 5-10 mm to obtain a diamond bead with a metal matrix 9, such as Figure 9 shown in . Then these beads 40 are strung on the φ1mm bending-resistant multi-strand steel wire rope 1 at intervals, and fixed with glue to obtain a semi-finished wire saw. Then coat a layer of polyurethane glue 5 on the space between the semi-finished products of the wire saw, and make such as Figure 4 The diamond wire saw shown in .
[0073] Such as Figure 4 with Figure 9 As shown in , a diamond wire saw includes a multi-strand steel wire rope 1 resistant to bending. The diameter of the steel wire rope 1 is 0.5-2.0 mm, and several ...
