Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] A method for preparing a multi-scale functional microstructure on a high-hardness surface, the specific steps are as follows:

[0032] Step 1. Use diamond to make a single-point diamond tip, such as Figure 4 As shown, wherein, the single-point diamond tip is rounded truncated, the angle between the generatrix of the single-point diamond tip and the central axis is θ1=θ=22.5°, and the maximum diameter of the single-point diamond tip is d1=D=1.5mm; The minimum diameter of the single-point diamond tip d2 = d = 0.2mm; the height of the single-point diamond tip h1 = 1.5h = 1.5mm; then, the single-point diamond tip is sintered on a handle to make a single-point diamond tool (single-edged), such as figure 2 shown. Single-point diamond tools are used to fabricate functional microstructures at the millimeter-submillimeter scale.

Abstract

The invention discloses a method and device for preparing a multi-scale functional microstructure on a high-hardness surface. It is very necessary to develop an efficient and convenient multi-scale functional microstructure preparation method and device. The method comprises the steps that a single-point diamond cutter and a multi-edge diamond cutter are manufactured; then, a central inverted circular truncated cone pit microstructure array or a V-shaped groove microstructure array is imprinted on the to-be-machined surface of the to-be-machined workpiece; and finally, preparing a micron or submicron functional microstructure on the central inverted circular truncated cone pit microstructure array or the V-shaped groove microstructure array. The device comprises a four-degree-of-freedom positioning mechanism, a clamp, a vibration exciter, a single-point diamond cutter and a multi-edge diamond cutter. The multi-scale functional microstructure is machined on the high-hardness surface, the hardness, strength, abrasion resistance and precision of the high-hardness surface can be improved, and the method has very important significance in development of the high-hardness machining industry.

Description

technical field [0001] The invention relates to a high-hardness surface functional microstructure, in particular to a preparation method and device for a high-hardness surface multi-scale functional microstructure. Background technique [0002] High-hardness surface tools such as turning tools and milling cutters have problems such as large cutting force and severe tool wear when processing difficult-to-machine materials in the aerospace, marine and automotive fields. Therefore, how to improve the cutting performance of tools and extend tool life has become a technical research. hotspots. [0003] Designing high-hardness surface functional microstructures on high-hardness surface tools can be widely used in processing difficult-to-machine materials such as titanium alloys, ceramics, and high-temperature nickel-based alloys; however, the current research on preparing multi-scale functional microstructures on high-hardness surfaces Very limited. For example, the patent with p...
