Embodiment 1
[0041] Such as Figure 1-4 Shown, a kind of high-precision double-edged diamond roller and its manufacturing method are characterized in that, the high-precision double-edged diamond roller comprises an annular matrix 1, and the center of the matrix 1 is provided with a roller passage for making the roller 7 pass through. Hole 11, the hole wall of the roller through hole 11 is provided with a taper, the taper is 5.5°, and the base 1 around the roller through hole 11 is provided with a ring-shaped table 2, and the ring-shaped table 2 is provided with 4 sets of cooling chambers 3. Six sets of main through-holes 21 are arranged parallel to the roller through-holes 11 in the circumferential direction of the circular table top 2, and three sets of equally spaced auxiliary through-holes 22 are arranged at intervals between the main through-holes 21. The auxiliary through-holes 22 The included angle with the circumferential distance between the adjacent main through holes 21 is 30°, ...
Embodiment 2
[0050] This embodiment is basically the same as Embodiment 1, the difference is:
[0051] Such as figure 1 , 5 , 6, the cooling cavity 3 is 3 groups, which are symmetrically arranged on both sides of the main through hole 21 one by one with the secondary through hole 22 respectively, and the circumferential spacing angle between the cooling cavity 3 and the adjacent main through hole 21 is 30°, a Y-shaped conduit 31 is symmetrically arranged in the cooling chamber 3, and the Y-shaped conduit 31 is connected to the branch pipe 72. Two rams 32 are symmetrically arranged at the connection, and the ram 32 is connected to the inner wall of the cooling chamber 3 through a spring, and the Y-shaped The bottom of the outer pipe wall of the inclined part on both sides of the conduit 31 is provided with a slide rail 33, and the slide rail 33 is provided with a slide ball 34 that can slide along the slide rail 33. The spring connected by the sliding ball 34, one branch pipe of the Y-sha...
Embodiment 3
[0058] This embodiment is basically the same as Embodiment 2, the difference is:
[0059] Step S2: Prepare metal alloy powder, mix alloy powder consisting of 30% copper and 70% iron, and mix diamond particles with a particle size of 55 μm and alloy powder at a ratio of 1:4.4 to obtain abrasive grains.
