Embodiment 1
[0035] like figure 2 As shown, the first bionic coupling element and the second bionic coupling element are made on the working surface of the guide rail, the first bionic coupling element is a strip-shaped bionic coupling element 11, and the second bionic coupling element is a pit-shaped coupling element 12; The angle between the strip-shaped bionic coupling element 11 and the load feeding direction is 90°, and the pit-shaped coupling elements 12 are arranged around the strip-shaped bionic coupling element 11 .
[0036] like image 3 As shown, the strip-shaped bionic coupling element 11 has a "U"-shaped cross section and forms a "soft and hard" columnar structure with the parent body. Its structure is composed of high-hardness carbide and martensite, and its surface width D is 0.6mm. ~2mm, depth A H 0.3mm~0.5mm; the pit-shaped coupling element 12 is a pit-shaped coupling element with a "U"-shaped ring-shaped cross-section after being processed by a high-energy laser beam, ...
Embodiment 2
[0041] like Figure 4 As shown, the first bionic coupling element and the second bionic coupling element are made on the working surface of the guide rail, the first bionic coupling element is a mesh bionic coupling element 21, and the second bionic coupling element is a pit-like coupling element 22; The angle between the strengthening part in the vertical direction of the mesh bionic coupling element 21 and the load feeding direction is 90°, and the pit-shaped coupling elements 12 are arranged in the grid of the mesh bionic coupling element 21 . The spacing and depth of the mesh-like bionic coupling elements 21, the cross-sectional shape and depth of the pit-like coupling elements 22, and the distance between the pit-like coupling elements 22 and adjacent mesh-like bionic coupling elements 21 are the same as those in Embodiment 1.
[0042]The surface of the guide rail along the working direction of the tool is processed to form a combination of multi-structure and different-d...
