Embodiment Construction
[0016] The present invention will be further described below in conjunction with embodiment.
[0017] A kind of grinding wheel cuts the method for the structural color metal surface based on blazing grating structure, comprises the following steps:
[0018] (1) Smooth the surface of the metal workpiece so that the surface roughness does not exceed 100nm;
[0019] (2) Use a grinding wheel to cut a specific group of parallel grooves on the surface of the metal workpiece according to specific process parameters.
[0020] The processing object of the inventive method is a metal workpiece made of a high-viscosity metal material (such as stainless steel or titanium alloy, etc.); the cutting related process parameters in the step (2) of the inventive method are as follows: the cutting selection specification is that the cutting selection specification is cubic Boron nitride particle size 1000#-8000#, abrasive grain concentration 100%-150% cast iron bond grinding wheel; when cutting,...

The invention provides a method for forming a structural-color metal surface based on a blazed grating structure through grinding wheel cutting. The method for forming the structural-color metal surface based on the blazed grating structure through grinding wheel cutting comprises the following steps that (1) the surface of a metal workpiece is flattened, so that the roughness of the surface of the metal workpiece is made not to exceed 100 nm, and hard alloy is adopted to serve as the metal workpiece; and (2) set parallel groove groups are cut in the surface of the metal workpiece through a grinding wheel according to set technological parameters, and after one groove is cut, the grinding wheel is made to deviate from the workpiece by 3-20 [mu]m for cutting of the next groove, wherein according to the technological parameters, the included angle between the grinding wheel and the surface of the workpiece is 5-30 degrees, the rotating speed of the grinding wheel is 1000-3000 rpm, the feeding speed is 20-100 mm / min, and the cutting depth is 1-5 [mu]m. The metal surface formed through the method is of a specific microstructure, can be in a structural color like a blazed grating, and has better hydrophobicity after being machined, thereby having better corrosion resistance and lower fluid flowing resistance.
Description
technical field [0001] The invention relates to the field of metal surface finishing, in particular to a method for cutting and shaping a structural color metal surface based on a blazed grating structure with a grinding wheel. Background technique [0002] For decorative purposes, changing the color of metal appearance at this stage relies on dyes. Dyeing with dyes will not only cause environmental pollution, but also easily fade and fade (especially when encountering certain chemical reagents). It can be seen that it is of great significance to study how to overcome the above-mentioned disadvantages or deficiencies in dyeing. [0003] Structural color, also known as physical color, is a luster caused by the wavelength of light and has nothing to do with pigment coloring. It will not fade or fade even when it encounters chemical reagents. It can be seen that if a microstructure capable of showing structural color can be processed on the metal surface, and the metal surfac...
