Embodiment 1

[0034] A method for processing a micro-textured cutter based on a silicon brass structure, comprising the steps of:

[0035] (1) Tool preparation: first select the YG8 cemented carbide tool and determine the cutting edge position to be processed, grind and polish the rake face of the tool with 1500# metallographic sandpaper, clean and dry with alcohol.

[0036] (2) Composite micro-texture design: place the polished tool on the laser processor, and focus the laser energy on the tool. Then, the composite micro-texture of convex texture and longitudinal texture was designed at 20 μm away from the cutting edge ( figure 1 and figure 2 ). Among them, within 140 μm from the cutting edge, there is a raised texture array, including the bottom of the cube with a side length of 50 μm and the trapezoidal platform at the top, and a single raised texture ( image 3 ) is rectangular, the length is consistent with the side length of the cube, and the width is 10 μm; the longitudinal textu...

[0041] A method for processing a micro-textured cutter based on a silicon brass structure, comprising the steps of:

[0042] (1) Tool preparation: first select the YG8 cemented carbide tool and determine the cutting edge position to be processed, grind and polish the rake face of the tool with 1500# metallographic sandpaper, clean and dry with alcohol.

[0043] (2) Composite micro-texture design: place the polished tool on the laser processor, and focus the laser energy on the tool. Then, the composite micro-texture of convex texture and longitudinal texture was designed at 10 μm away from the cutting edge ( figure 1 and figure 2 ). Among them, within 110 μm from the cutting edge, there is a raised texture array, including the bottom of the cube with a side length of 40 μm and the trapezoidal platform at the top, and a single raised texture ( image 3 ) is rectangular, the length is the same as the side length of the cube, and the width is 15 μm; the longitudinal texture p...

[0048] A method for processing a micro-textured cutter based on a silicon brass structure, comprising the steps of:

[0049] (1) Tool preparation: first select the YG8 cemented carbide tool and determine the cutting edge position to be processed, grind and polish the rake face of the tool with 1500# metallographic sandpaper, clean and dry with alcohol.

[0050] (2) Composite micro-texture design: place the polished tool on the laser processor, and focus the laser energy on the tool. Then, a composite micro-texture of convex texture and longitudinal texture was designed at a distance of 30 μm from the cutting edge ( figure 1 and figure 2 ). Among them, within 150 μm from the cutting edge, there is a raised texture array, including the bottom of the cube with a side length of 45 μm and the trapezoidal platform at the top, and a single raised texture ( image 3 ) is rectangular, the length is the same as the side length of the cube, and the width is 20 μm; the longitudinal te...

Abstract

The invention relates to a silicon-brass-structure-based micro-texture tool and a machining method and application thereof and belongs to the technical field of the cutting of high-performance alloy materials. The silicon-brass-structure-based micro-texture tool is characterized in that a composite micro-texture is arranged in a certain area of a tool cutting edge and comprises a convex texture array and a longitudinal texture array, and the convex texture array is located between the cutting edge and the longitudinal texture array; the convex texture array comprises a plurality of convex textures which are arranged into a rectangular array, the bottom of each convex texture is a cube, and the upper end of each convex texture is a trapezoid platform; the longitudinal texture array comprises a plurality of longitudinal textures which are arranged in a row, the longitudinal textures are cuboids, and the length direction of the longitudinal textures is vertical to the width direction of the cutting edge. The silicon-brass-structure-based micro-texture tool has the advantages that chips obtained by the tool are curly and tiny, and the chip breaking performance of the alloy materials isincreased greatly.

Description

technical field [0001] The invention relates to the technical field of cutting processing of high-performance alloy materials, in particular to a micro-textured tool based on a silicon brass structure and its processing method and application. Background technique [0002] As a typical representative of copper alloy, lead brass is widely used in the manufacture of electronic and electrical parts, instrumentation parts, sanitary products and children's toys because of its excellent strength, toughness, corrosion resistance, machinability and easy formability. However, lead is a heavy metal element. When lead brass products are not disposed of properly during long-term use or after being scrapped, it is easy to have a great impact on human health and the natural environment. Therefore, the development of new types of free-cutting environment-friendly brass has become a problem that people pay more and more attention to. In view of this, the development and application of sili...
