Description

Technical Field

[0001] The present invention relates to the field of processing technology, in particular to a surface processing method and a product thereof. Background Art

[0002] In the processing industry, it is often necessary to smooth the surface of the workpiece so that the smooth surface can achieve the effect of mirror reflection. Its dazzling characteristics can play a decorative and beautifying role. Among the common smoothing methods currently used, one is to smooth by cutting the material. Specifically, during cutting, the tool of the machine tool rotates at high speed. When the tool touches the surface of the workpiece during rotation, it can cut and smooth the surface of the workpiece. However, the surface effect produced by this method is still not bright and dazzling enough. Summary of the Invention

[0003] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a surface processing method and product thereof, which can make the processed surface brighter and more dazzling.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] In a first aspect, a surface processing method comprises the following steps:

[0006] S1, rough machining the blank surface to obtain the basic surface;

[0007] S2, using a machine tool to perform fine processing on the surface of the blank obtained in S1. Specifically, a CVD diamond knife is used as the processing tool. During fine processing, the CVD diamond knife does not apply a cutting speed. The blade of the CVD diamond knife is cut on the surface of the blank along a preset path with a preset cutting depth and a preset cutting speed. Moreover, under the control of the machine tool, the blade surface of the CVD diamond knife is always perpendicular to the cutting direction of the trajectory of the CVD diamond knife projected on the plane.

[0008] As a preferred solution, before performing step S2, the surface of the blank is first polished.

[0009] As a preferred solution, the preset cutting depth is 0.01 mm-0.03 mm.

[0010] As a preferred solution, the preset cutting speed is 0.1m / s-0.2m / s.

[0011] As a preferred solution, the clearance angle of the CVD diamond knife is 0.5°-0.8°.

[0012] A second aspect provides a product having a surface processed by the surface processing method according to the first aspect.

[0013] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that it mainly processes the surface of the workpiece by using a CVD diamond knife. During processing, the CVD diamond knife does not apply a cutting speed. The blade of the CVD diamond knife is cut on the surface of the blank along a preset path with a preset cutting depth and a preset cutting speed. Moreover, under the control of the machine tool, the blade surface of the CVD diamond knife is always perpendicular to the cutting direction of the trajectory of the CVD diamond knife projected on the plane. Compared with the prior art, this process can make the processed surface brighter and more dazzling.

[0014] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the product effect of an embodiment of the present invention. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0018] An embodiment of the present invention provides a surface processing method, comprising the following steps:

[0019] S1, rough machining the blank surface to obtain the basic surface;

[0020] S2, using a machine tool to perform fine processing on the surface of the blank obtained in S1. Specifically, a CVD diamond knife is used as the processing tool. During fine processing, the CVD diamond knife does not apply a cutting speed. The blade of the CVD diamond knife is cut on the surface of the blank along a preset path with a preset cutting depth and a preset cutting speed. Moreover, under the control of the machine tool, the blade surface of the CVD diamond knife is always perpendicular to the cutting direction of the trajectory of the CVD diamond knife projected on the plane; in this way, the processed surface can be made brighter and more dazzling.

[0021] Furthermore, before performing step S2, the surface of the blank is first polished, so that the surface of the blank can be modified in advance to facilitate subsequent finishing.

[0022] Specifically:

[0023] The blank can be made of metal, such as gold, platinum, K gold, etc. As for the cutting tool, a CVD diamond knife needs to be used. If an MCD diamond knife or a PCD diamond knife is used, the required reflective effect cannot be achieved. Furthermore, the back angle of the CVD diamond knife cannot be too large. In this embodiment, the back angle of the CVD diamond knife is 0.5°-0.8°, preferably 0.5°.

[0024] In step S2, during the cutting process, the CVD diamond cutter scrapes the surface of the blank without rotating. In the traditional finishing method, the cutter needs to rotate, cutting the surface of the blank during the rotation to achieve finishing. This method easily produces marks and does not reflect the more excellent mirror effect. However, the product manufactured by the method of the present application will have a very dazzling effect when illuminated by light.

[0025] During the tool feeding process, because the preset path is usually not a single straight line, but an irregular trajectory, in order to make the blade surface of the CVD diamond knife always perpendicular to the tool feeding direction of the trajectory of the CVD diamond knife projected on the plane, the machine tool needs to control the rotation of the CVD diamond knife (the rotation here is used to adjust the direction of the blade surface of the CVD diamond knife in the circumferential direction, not to achieve the rotation of traditional cutting) to adjust the direction of the blade surface of the CVD diamond knife so that the blade surface of the CVD diamond knife is always perpendicular to the tool feeding direction of the trajectory of the CVD diamond knife projected on the plane. Here, it is necessary to To explain the trajectory of the CVD diamond knife on the plane projection, in reality, the surface of the blank workpiece has both flat and curved surfaces. For the curved surface, the actual tool path of the CVD diamond knife is not on the same plane, but will fluctuate up and down along the curved surface. At this time, the machine tool ignores the up and down path of the tool path and only refers to the path of the tool path on the horizontal plane (that is, the trajectory of the plane projection) to adjust the direction of the blade surface of the CVD diamond knife. In addition, when rotating and adjusting the blade surface of the CVD diamond knife, the faster the tool speed, the faster the rotation of the CVD diamond knife when adjusting the direction.

[0026] It should be noted that in one pass, the CVD diamond tool can only move forward and not backward, and the preset cutting depth of each pass should not be too deep. The preset cutting depth is not greater than 0.01mm-0.03mm, preferably 0.01mm. If it is too deep, the tool may break easily. The preset cutting speed should not be too fast either. The preset cutting speed is 0.1m / s-0.2m / s, preferably 0.1m / s. If it is too fast, the tool may break easily. Multiple passes can be performed to achieve the final desired chip depth.

[0027] Also, during the machining process, use a coolant that can cool quickly, such as a water-soluble coolant.

[0028] The embodiment of the present invention further provides a product having a surface processed by the aforementioned surface processing method. The product can be in the form of any animal in the twelve zodiac signs, as a decoration, such as a rabbit, dog, cow, tiger, etc. Of course, it can also be an object in other forms, without limitation, such as Figure 1 , which contains products processed using the process of this application, including rabbits, cows, dogs and dolphins. As long as any surface of the object is processed using this process, it is within the scope of protection of this application.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
