Abstract
The present invention relates to a method for machining mirror-surface aluminium products, which comprises the following steps: firstly, in a punch machining step, machining mirror-surface aluminium materials in order to form the external shape of a preconcerted aluminium product; successively, in a laser engraving step, forming the preconcerted characters or patterns at the position of the mirror surface of the aluminium product which has the preconcerted external shape; finally, in an anodic oxidation treatment step, obtaining an oxide film protection layer by treating the surface of the aluminium product treated by the previous steps. The mirror-surface aluminium product is obtained by machining the mirror-surface aluminium materials in the punch processing step, the laser engraving step and the anodic oxidation treatment step. The present invention has the advantages of simple machining procedure and high machining efficiency and can also guarantee machining precision, so the effect of prospective alternate bright-dark brightness and high metal texture on the surface of the product can be obtained. In addition, the visual effect is excellent.
Description
[technical field]
The present invention relates to a kind of aluminium machining method, relate in particular to a kind of aluminium machining method with mirror surface.
[background technology]
Existing electronic product, especially some fashion type electronic products, all pursue cruel, dizzy appearance as mobile phone, MP3, digital camera etc., at present, these electronic products normally adopt plastic parts to make shell plates one deck light again at outer surface metal level, and process some literal or figure on the outer surface, and make product have the appearance of metal-like and light, give visual impact.Yet, the electronic product that this mode processes in use for some time, the electrodeposited coating of outer surface very easily weares and teares and peels off, and loses metallic luster, it is comparatively ugly that outward appearance becomes.For this reason, industry also attempts directly making these electronic product shell with metal as metallic aluminium, handles obtaining outward appearance preferably again at its outer surface.Its main process is to mold appearance profile by aluminum profile extrusion earlier, and then carry out anodized and literal or figure on the surface and process, the processing mode that literal or figure adopted mainly is repeatedly oxidation or silk-screen mode, yet, this mode not only working (machining) efficiency is low, and precision is not high, and qualification rate is lower.
[summary of the invention]
For solving the problem of above-mentioned existence of the prior art, the invention provides a kind of aluminium machining method with mirror surface, its process is simple, working (machining) efficiency height and precision height.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of aluminium machining method with mirror surface is provided, comprises the steps:
At first, carry out the punch process step, adopt the minute surface aluminium to mold predetermined aluminum products profile through punch process;
Then, carry out the laser engraving step, carry out laser engraving at the minute surface position of aluminum products and form predetermined literal or figure with predetermined profile;
At last, carry out the anodic oxidation step again, will carry out anodized and obtain the oxide film protection layer through the aluminum products surface that abovementioned steps is handled.
Owing to adopt technique scheme, the present invention has following beneficial effect: handle by specular aluminium being carried out punch process, laser engraving and anodic oxidation processing, process is very simple, the working (machining) efficiency height, and can guarantee the precision of processing, thereby can obtain light and dark light, the metal-like of expection on the specular aluminium surface, visual effect is splendid.
[description of drawings]
Fig. 1 is the work flow schematic diagram of a kind of aluminium machining method with mirror surface of the present invention.
Fig. 2 is the work flow schematic diagram of the another kind of embodiment of a kind of aluminium machining method with mirror surface of the present invention.
[specific embodiment]
The invention provides a kind of aluminium machining method with mirror surface, it mainly comprises following three basic steps:
At first, the punch process step adopts the minute surface aluminium to mold predetermined aluminum products profile through punch process;
Then, the laser engraving step is carried out laser engraving and is formed predetermined literal or figure at the minute surface position of the aluminum products with predetermined profile;
At last, the anodic oxidation step will be carried out anodized and obtain the oxide film protection layer through the aluminum products surface that abovementioned steps is handled.
The surface reflectivity of the specular aluminium that adopts in the punch process step is advisable with 60～95%.
Surface quality according to the employing aluminium, if the aluminium material surface reflectivity that is adopted is not high, when not reaching the minute surface requirement, then as shown in Figure 2, it also can increase by a polishing step again before the punch process step, it is used for that aluminium is carried out surface finish and handles, so that process required minute surface aluminium.
In the anodic oxidation step, by in anode oxidation treatment liquid, increasing or change corresponding coloring agent component and in the aluminum products surface colour, as, can be coloured to different colors such as blueness, green.
Like this; aluminium machining method with mirror surface of the present invention has been guaranteed the basic profile of goods by punch process; can on product surface, form predetermined literal, figure etc. through laser engraving again; have appearance attractive in appearance, and promptly can form layer of oxide layer with the protection aluminum substrate at product surface through anodized.Three step process are very simple, and the working (machining) efficiency height, and the precision of laser engraving is very high.In addition, select for use specular aluminium to come each aluminum products of machine-shaping, metal-like is strong, the light and dark light that the surface can obtain to expect, and visual effect is splendid.
Claims (4)
