Embodiment 1
[0032] Taking red copper as the sheet material for processing the heat exchange plate, and the second-order V-shaped fractal microchannel as an example, the process is as follows:
[0033] (1) Preliminary processing of raw materials. First, remove the burr from the 50×100×3mm sheet, then fix it on the fixture, install it on the BC6063B planer vise, and use the dial indicator to level the surface of the sheet.
[0034] (2) Tool clamping. The selected multi-stage composite fractal plow cutting tool is installed on the tool holder, and the verticality corrector is used to ensure that the angle between the tool and the surface of the sheet to be processed is 90°. The material of the tool is high-speed steel, and the shape of the cutting edge is controlled by the trajectory of the wire-cut molybdenum wire, so that it has a 3-order V-shaped fractal structure, such as figure 1 , figure 2 shown. Taking the two-stage composite plow cutting tool as an example, the depth of the firs...
Embodiment 2
[0038] Taking red copper as the sheet material for processing the heat exchange plate, and the second-order V-shaped fractal microchannel as an example, the process is as follows:
[0039] (1) Preliminary processing of raw materials. First remove the burrs from the 50×100×15mm sheet, then install it on the BC6063B planer, use the planer to plan the surface to be processed, turn the sheet 180° after completion, and continue to process the other side with the planer , to ensure the parallelism and flatness of the two planes.
[0040] (2) Tool clamping. The selected multi-stage composite fractal plow cutting tool is installed on the tool holder, and the verticality corrector is used to ensure that the angle between the tool and the surface of the sheet to be processed is 90°. The cutting tool material is high-speed steel, and the cutting edge shape is controlled by wire cutting molybdenum wire track 1, so that it has a V-shaped fractal structure, such as figure 1 , figure 2A...
