Method of processing a striking face of a golf club head

Abstract

The present disclosure relates to a method for processing a striking face of a golf club head. In the method, a golf club head is milled to flatten a striking face of the golf club head. A scraping tool is selected according to a scraping pattern, and the scraping tool is mounted on a scraping handle. The scraping pattern is a symmetric or asymmetric pattern, and the scraping pattern includes a plurality of three-dimensional structures. The striking face is scraped according to the scraping pattern by moving the golf club head relative to the scraping tool, so as to scrape the scraping pattern on the striking face by the scraping tool. Since the scraping tool does not rotate during the scraping process, a larger tool can be selected, and the processing efficiency is high. In addition, the scraping process can set the angle of the structure of the pattern according to the ball hitting requirements, and the microstructure of the pattern can be asymmetric or symmetric, so that the appearance design of the pattern is more changeable.

Description

Technical Field

[0001] This disclosure relates to a golf club manufacturing technique, and more particularly to a method for processing the striking face of a golf club head. Background Technology

[0002] With the increasing popularity of golf, manufacturers are constantly striving to improve the performance of golf clubs, giving them better hitting characteristics. A golf club mainly consists of the clubhead, shaft, and grip. Currently, most clubheads have grooved surfaces on the striking face to increase friction and spin on the ball.

[0003] The texture of the striking face of commercially available golf clubs is generally a relatively regular shape or pattern. Currently, milling, laser processing, and chemical solutions are used to process the texture of the striking face. When milling the striking face, the tool rotates to remove part of the material from the striking face, thereby forming the texture. However, milling tools are small in size, resulting in low processing efficiency. In addition, milling can only create textures with symmetrical structures, that is, the peak angles of the microstructure of the texture are symmetrical.

[0004] On the other hand, when using lasers to process the texture of the impact surface, the laser ablates a portion of the material on the impact surface, thereby forming the texture. However, the thermal energy of the laser can alter the surface material properties of the impact surface, affecting its performance. Using chemical solutions to erode the impact surface and create textures presents problems such as chemical contamination and difficulty in controlling the precision of the texture. Summary of the Invention

[0005] Therefore, one objective of this disclosure is to provide a method for machining the striking surface of a golf club head, which involves scraping the flat striking surface of the club head to form scraping textures containing multiple three-dimensional structures. Since the scraping tool does not rotate during the scraping process, a larger tool can be used, resulting in high machining efficiency. Furthermore, the angle of the texture structure can be set according to the shot requirements, and the microstructure of the texture can be asymmetrical or symmetrical, allowing for greater variation in the texture's appearance.

[0006] Another objective of this disclosure is to provide a method for processing the striking face of a golf club head, which can form a scraping texture containing multiple three-dimensional structures on the striking face of the golf club head, with adjacent rows of three-dimensional structures being staggered. Therefore, this scraping texture not only increases the friction between the striking face of the golf club head and the golf ball, but also balances the control of the golf ball's trajectory on the striking face, and provides a three-dimensional effect in appearance.

[0007] In accordance with the aforementioned objectives of this disclosure, a method for machining the striking face of a golf club head is proposed. In this method, the golf club head is milled to smooth its striking face. A scraping tool is selected based on a scraping pattern and mounted on a scraping tool holder. This scraping pattern can be symmetrical or asymmetrical and includes multiple three-dimensional structures. The striking face is scraped by moving the golf club head relative to the scraping tool according to the scraping pattern, thereby using the scraping tool to scrape the pattern onto the striking face.

[0008] According to one embodiment of this disclosure, when performing the above-mentioned scraping operation, the angle between the spindle of the scraper handle and the striking surface is 0 degrees to 90 degrees.

[0009] According to one embodiment of this disclosure, when performing the above-mentioned scraping operation, the rake angle of the scraping tool is 60 degrees to 120 degrees.

[0010] According to one embodiment of this disclosure, the scraping tool described above is a single-tooth tool.

[0011] According to one embodiment of this disclosure, the scraping tool described above is a multi-tooth tool.

[0012] According to one embodiment of this disclosure, performing the above-mentioned scraping operation includes controlling the movement of the golf club head based on the scraping pattern using computer numerical control (CNC).

[0013] According to one embodiment of the present disclosure, the above-mentioned three-dimensional structures are arranged in multiple columns, and any two adjacent columns of three-dimensional structures are staggered with each other.

[0014] According to one embodiment of this disclosure, the columns extend in a direction parallel to the horizontal plane.

[0015] According to one embodiment of this disclosure, the extension direction of these columns is perpendicular to the horizontal plane.

[0016] According to one embodiment of the present disclosure, the extension direction of these columns has an angle of inclination relative to the horizontal plane, such that the columns are neither parallel to nor perpendicular to the horizontal plane. Attached Figure Description

[0068] The embodiments of this disclosure are discussed in detail below. However, it will be understood that the embodiments provide many applicable concepts that can be implemented in a wide variety of specific situations. The embodiments discussed and disclosed are for illustrative purposes only and are not intended to limit the scope of this disclosure. All embodiments of this disclosure reveal a variety of different features, but these features can be implemented individually or in combination as needed.

[0069] Furthermore, the terms "first," "second," etc., used in this article do not specifically refer to order or sequence; they are merely used to distinguish elements or operations described using the same technical terms.

[0070] The spatial relationship between the two elements described in this disclosure applies not only to the orientation shown in the accompanying drawings, but also to orientations not shown in the drawings, such as inverted orientations. Furthermore, the terms "connection," "electrical connection," or similar expressions used in this disclosure to refer to two components are not limited to a direct or electrical connection, but may also include indirect or electrical connections as needed.

[0071] Please refer to Figure 1 and Figure 2 The diagrams illustrate a process flow chart of a method 100 for processing the striking face 210 of a golf club head 200 according to an embodiment of this disclosure, and a schematic diagram of an apparatus for processing the striking face 210 of the golf club head 200. When processing the striking face 210 of the golf club head 200 using the processing method 100, step S1 can be performed first to mill the golf club head 200, thereby smoothing the striking face 210. That is, the striking face 210 is first milled into a flat surface. During the milling operation, the golf club head 200 can be fixed on the milling platform of the milling apparatus, and then the golf club head 200 can be milled using a milling cutter to remove a portion of the golf club head 200, thereby smoothing the striking face 210 of the golf club head 200.

[0072] In some embodiments, the entire golf club head 200 can be fixed to a milling platform during milling operations. In such embodiments, the golf club head 200 is a one-piece structure. In other embodiments, the golf club head 200 may not be a one-piece structure, but may comprise a body and a striking plate fixed to the body. In such embodiments, during milling operations, only a portion of the golf club head 200, i.e., the striking plate, can be fixed to the milling platform for the milling operation.

[0073] After the milling operation is completed, step S2 can be performed to select an appropriate scraping tool 320 according to the pre-designed scraping pattern, and to install and fix this scraping tool 320 on the spindle 310 of the scraping tool holder 300. Figure 2 In the embodiment shown, the scraping tool 320 is substantially parallel to the spindle 310. Figure 3 In the illustrated embodiment, the scraping tool 320 is substantially perpendicular to the spindle 310. However, this disclosure is not limited to this, and the angle between the scraping tool 320 and the spindle 310 can be adjusted according to operational requirements. For example, the angle between the scraping tool 320 and the spindle 310 can range from 0 degrees to 90 degrees. In this embodiment, the designed scraping pattern is a symmetrical or asymmetrical pattern, such as a square pattern, a circular pattern, or a wave pattern, wherein the scraping pattern includes multiple three-dimensional structures. In some embodiments, the scraping pattern can be a wave pattern, and this wave pattern includes multiple three-dimensional wave crest structures.

[0074] Please refer to Figure 4 and Figure 5 The figures shown are a front view and a side view of a scraping tool 320 according to one embodiment of the present disclosure. In this embodiment, the scraping end 322 of the scraping tool 320 has a single tooth 324 and is a single-tooth tool.

[0075] In another embodiment, such as Figure 6 As shown, the scraping tool 320a is a multi-tooth tool, and the scraping end 322a of the scraping tool 320a has multiple teeth 324a. During the scraping operation, the multiple teeth 324a of the scraping tool 320a scrape the surface to be scraped simultaneously.

[0076] Please refer to the following at the same time Figure 2 , Figure 7 ,and Figure 8 ,in Figure 7 and Figure 8These are front and side views of a scraping tool 320 and a golf club head 200, respectively, illustrating the processing of the striking face 210 of a golf club head 200 according to an embodiment of this disclosure. Next, step S3 can be performed to scrape the striking face 210 of the golf club head 200, creating scraping patterns on the striking face 210. During the scraping operation, the scraping end 322 of the scraping tool 320 is placed against the striking face 210 of the golf club head 200, and the golf club head 200 is moved relative to the scraping tool 320 according to a preset scraping pattern, thereby scraping the pattern onto the striking face 210 using the scraping tool 320. The scraping tool 320 does not rotate during the scraping operation. In some embodiments, during the scraping operation, computer numerical control is used to control the movement of the golf club head 200 according to the scraping pattern.

[0077] During scraping operations, the angle between the spindle 310 of the scraper handle 300 and the striking surface 210 can be from 0 degrees to 90 degrees. For example, such as Figure 2 As shown, in this embodiment, during the scraping operation, the spindle 310 of the scraper handle 300 is substantially perpendicular to the striking surface 210, that is, the angle between the spindle 310 and the striking surface 210 is 90 degrees. And... Figure 3 In the embodiment shown, when performing the scraping operation, the spindle 310 of the scraper handle 300 is substantially parallel to the striking surface 210, and the angle between the spindle 310 and the striking surface 210 is 0 degrees.

[0078] exist Figure 8 In the illustrated embodiment, the rake angle θ of the scraping tool 320 is substantially 90 degrees. In this embodiment, during scraping operations, the rake angle θ of the scraping tool 320 can be, for example, 60 degrees to 120 degrees. Specifically, when the rake angle θ is 60 degrees, it is... Figure 8 The scraping tool 320 is inclined at 30 degrees toward the impact surface 210 in the machining direction PD; while when the rake angle θ is 120 degrees, it is... Figure 8 The scraping tool 320 is inclined at 30 degrees toward the striking surface 210 in the opposite direction to the machining direction PD.

[0079] Please refer to Figure 9 This is a top view schematic diagram illustrating a scraping tool 320 and a golf club head 200 during the machining of the striking face 210 according to an embodiment of the present disclosure. During the scraping operation, the rake face 326 of the scraping tool 320 forms an angle β with the machining direction PD. In some embodiments, the angle β is 90 degrees ± 30 degrees.

[0080] The processing method 100 disclosed herein can also be used for scraping operations on uneven surfaces. Please refer to... Figure 10This is a side view of the scraping tool 320 and the golf club head 200a during the machining of the striking face 210a according to another embodiment of this disclosure. In this embodiment, the striking face 210a of the golf club head 200a is a curved surface, rather than a flat surface. The scraping tool 320 can also perform scraping operations on the curved striking face 210a, thereby forming a three-dimensional structure of scraping texture on the striking face 210a.

[0081] Please refer to Figure 11 This is a top view schematic diagram illustrating a scraping texture 400 according to an embodiment of the present disclosure. In this embodiment, the processing method 100 forms a three-dimensional scraping texture 400 on the impact surface 210. The scraping texture 400 includes a plurality of three-dimensional structures 410. These three-dimensional structures 410 are arranged in multiple rows 400R, and these rows 400R all extend along the extension direction ED1. Furthermore, the three-dimensional structures 410 of any two adjacent rows 400R are misaligned with each other, for example, the three-dimensional wave crest structures of an ocean wave pattern are misaligned with each other, so that when there is relative movement between the viewer's line of sight and the impact surface 210, the scraping texture 400 can present a three-dimensional visual effect. For example, when the impact surface 210 is a metal surface, because the three-dimensional structures 410 between two adjacent rows 400R are misaligned with each other, the scraping texture 400 can present a visual effect of light and shadow flickering. In this embodiment, the extension direction ED1 of these rows 400R is parallel to the horizontal plane L.

[0082] Please refer to Figure 12 This is a top view schematic diagram illustrating a scraping texture 500 according to another embodiment of the present disclosure. The scraping texture 500 has a structure substantially the same as the scraping texture 400 described above. The scraping texture 500 also includes a plurality of three-dimensional structures 510 arranged in multiple columns 500R. These columns 500R all extend along the extending direction ED2, and any two adjacent columns of three-dimensional structures 510 are staggered from each other. The difference between scraping texture 500 and 400 is that the extending direction ED2 of the three-dimensional structures 510 in each column 500R is perpendicular to the horizontal plane L.

[0083] Please refer to Figure 13 This is a top view schematic diagram illustrating a scraping texture 600 according to another embodiment of the present disclosure. The scraping texture 600 has a structure substantially the same as the scraping texture 400 described above. The scraping texture 600 also includes a plurality of three-dimensional structures 610 arranged in multiple rows 600R. Each row 600R extends along the extending direction ED3, and any two adjacent rows of three-dimensional structures 610 are offset from each other. The difference between scraping texture 600 and 400 is that the extending direction ED3 of each row of three-dimensional structures 610 has an angle of inclination α relative to the horizontal plane L. The angle of inclination α is neither 0 degrees nor 90 degrees, therefore each row of 600R is neither parallel nor perpendicular to the horizontal plane L.

[0084] The serrations 400, 500, and 600 on the striking face 210 not only give it a beautiful three-dimensional visual effect, but also improve the hitting performance of the golf club head 200. Please refer to... Figure 14 This is a side view schematic diagram illustrating a golf club head 200 in accordance with an embodiment of the present disclosure during impact. When the golf club head 200 strikes the golf ball B, the three-dimensional structure 410 of the scraping groove 400 is still in contact with the golf ball B as it bounces outward from the golf club head 200. Therefore, the scraping groove 400 can increase the friction between the striking surface 210 of the golf club head 200 and the golf ball B, and can balance the control of the striking surface 210 over the trajectory of the golf ball B.

[0085] As can be seen from the above embodiments, one advantage of this disclosure is that the processing method performed a scraping operation on the flat striking surface of the golf club head to form scraping textures containing multiple three-dimensional structures on the striking surface. Since the scraping tool does not rotate during the scraping process, a larger tool can be used, resulting in high processing efficiency. Furthermore, the angle of the texture structure can be set according to the hitting requirements, and the microstructure of the texture can be asymmetrical or symmetrical, making the appearance design of the texture more varied.

[0086] Another advantage of this invention is that the processing method can form a multi-dimensional textured surface on the striking surface of a golf club head, with adjacent rows of textures being staggered. Therefore, this textured surface not only increases the friction between the club head and the golf ball, but also balances the club head's control over the ball's trajectory, and provides a more visually appealing three-dimensional effect.

[0087] Although this disclosure has been shown above by way of embodiments, it is not intended to limit this disclosure. Anyone skilled in the art can make various modifications and refinements without departing from the spirit and scope of this disclosure. Therefore, the scope of protection of this disclosure shall be determined by the appended claims.
