Description

本発明は、ゴルフクラブヘッドの付属品の製造方法に関するもので、特に、ゴルフクラブヘッドのフェース板の製造方法に係るものである。   The present invention relates to a method for manufacturing a golf club head accessory, and more particularly to a method for manufacturing a face plate of a golf club head.

一般的に、ゴルフクラブヘッドのフェース板の内側において不等厚構造を形成することにより、打球のスイートスポットを拡大することができ、さらにゴルフクラブヘッドの打球の効果を高めることができることは知られている。そして、現在では、ゴルフクラブヘッドの内側の不等厚構造は、多くはＣＮＣ加工機を用いて図案の電子ファイルを読み取って、かつそれぞれの刃具を利用して直接３Ｄによる切削を行うことによって作成することができる。   In general, it is known that by forming an unequal thickness structure inside the face plate of a golf club head, it is possible to expand the sweet spot of the hit ball and further enhance the effect of the hit ball of the golf club head. ing. At present, the unequal thickness structure inside the golf club head is often created by reading the electronic file of the design using a CNC processing machine and cutting directly by 3D using the respective cutting tools. can do.

しかし、刃具の制限により、加工後の完成品の外形は常に元の設計の３Ｄ図案の電子ファイルとは少しの差異が存在し、かつ加工の工程において刃具の切削で生じられる鋭角によってフェース板の強度に影響を及ぼしてしまうこともある。また、直接板材に対して切削加工を行うと、切削しなければならない廃材が増えるため、原材料の浪費になるだけではなく、刃具の損耗率も高くなり、さらに製造上において加工時間が長くなり（約８分間で一個のフェース板の成形加工を完成する。）、生産能力を上げることは難しいものである。多くの業者はＣＮＣ加工機の台数を増やす方法でしか生産量を増やしていく方法がないため、工場の空間を沢山占めるだけではなく、ＣＮＣ加工機の購入費用やメンテナンスなどのコストも高くなる。   However, due to the limitations of the cutting tool, the outer shape of the finished product after processing always differs slightly from the electronic file of the original 3D design, and the face plate has a sharp angle caused by cutting of the cutting tool in the processing process. It may affect the strength. In addition, cutting directly on the plate material increases the amount of waste material that must be cut, which not only wastes raw materials, but also increases the wear rate of the blade and further increases the processing time in production ( It takes about 8 minutes to complete the molding process of one face plate.) It is difficult to increase the production capacity. Many vendors have no way of increasing production only by increasing the number of CNC machines, which not only occupies a lot of factory space, but also increases the cost of purchasing and maintaining CNC machines.

中華民国公告第Ｉ２７０４２１号の「ゴルフクラブヘッドの恒温鍛造方法」においては、もう一種のフェース板の鍛造の成形方法が掲示されている。それは、片材を利用して予め成形しようとする輪郭になるようにプレス成形し、それから上記片材と成形金型を加熱し、さらに油圧式の鍛造機械を用いて上記片材を予め加熱された成形金型の中に置き入れ、油圧式を用いて鍛造成形させ、最後にフライス盤などの工作機械を用いて上記片材の外側の輪郭を必要とする外形まで切削し、それからサンドブラストの表面処理を行うものである。これにより、恒温鍛造の方法によって片材のサイズの厚さを容易に制御することができるため、鍛造後に生じる廃材を減らすことができるとともに、サイズの制御が難しいために生じていた余分な加工（例えば、表面研磨など）の製造工程を省くことができるため、製造工程の効率を高めることができるようにしたものがある。   In the “Constant Temperature Forging Method of Golf Club Head” published by the Republic of China No. I270421, another type of forging method of face plate is posted. It is press-molded using a single piece so as to have a contour to be molded in advance, then the piece and the mold are heated, and the piece is preheated using a hydraulic forging machine. Place it in a molding die, forge-mold using a hydraulic method, and finally cut the outer contour of the above-mentioned piece material to the required outline using a machine tool such as a milling machine, and then surface treatment of sandblast Is to do. As a result, the thickness of the piece material can be easily controlled by the constant temperature forging method, so that the waste material generated after forging can be reduced and the extra processing that has occurred because the size control is difficult ( For example, there is one that can increase the efficiency of the manufacturing process because the manufacturing process of surface polishing or the like can be omitted.

中華民国公告第Ｉ２７０４２１号Republic of China Notice No. I270421

上記のような従来のゴルフクラブヘッドのフェース板の製造方法では、一般的に下記の問題点を有する。従来のゴルフクラブヘッドのフェース板の製造方法では、鍛造成形の方法を利用してゴルフクラブヘッドのフェース板を製造するが、その工作機械を用いて加工する部分は部材の外縁の輪郭に対して修整を行うものであって、部材の表面の輪郭に対して修整を行うものではない。そのため、上記の方法では比較的一般的なフェース板の製造にしか適合できないものである。仮に、上記の方法を内側に不等厚構造を有するフェース板の製造に応用すると、フェース板の不等厚構造を成形するためには、不等厚構造に相対するもう一つの表面（すなわち、フェースとしての表面）は鍛造後では凹凸を有する平らではない形状に形成しなければならない。しかし、上記方法では上記フェースとしての表面を如何に修整すべきかについて掲示しておらず、そのために上記方法では内側に不等厚構造を有するフェース板の製造に適用できないという問題点があった。そのため、上述したような従来のゴルフクラブヘッドのフェース板の製造方法をさらに改良することが希求されていた。   The conventional method for manufacturing a face plate of a golf club head as described above generally has the following problems. In the conventional manufacturing method of the face plate of a golf club head, the face plate of the golf club head is manufactured by using a forging method, but the portion to be processed using the machine tool corresponds to the contour of the outer edge of the member. It is intended to modify, not to the contour of the surface of the member. For this reason, the above-described method can only be applied to the production of a relatively general face plate. If the above method is applied to the manufacture of a face plate having an unequal thickness structure on the inside, in order to form the unequal thickness structure of the face plate, another surface opposite to the unequal thickness structure (i.e., The surface as the face) must be formed in a non-flat shape having irregularities after forging. However, the above method does not show how the surface of the face should be modified, and therefore, there is a problem that the above method cannot be applied to the production of a face plate having an unequal thickness structure inside. Therefore, there has been a demand for further improvement of the conventional method for manufacturing the face plate of the golf club head as described above.

本発明はこのような問題点に鑑みて考案されたものであって、その目的とするところは、先にフェース板の一つの表面において不等厚構造を成形し、それからフェース板のもう一つの表面をフライス切削することにより、製造コストを抑えるとともに、生産能力を高めることができるゴルフクラブヘッドのフェース板の製造方法を提供することにある。   The present invention has been devised in view of such problems, and its object is to first form an unequal thickness structure on one surface of the face plate, and then to another surface plate. An object of the present invention is to provide a method for manufacturing a face plate of a golf club head that can reduce the manufacturing cost and increase the production capacity by milling the surface.

上記目的を達成するために、本発明によるゴルフクラブヘッドのフェース板の製造方法は、材料準備の段階、成形の段階およびフライス切削の段階を含む。材料準備の段階では加工処理を行なおうとする板材を準備する。板材には相対する一個の第一表面と一個の第二表面が含まれる。成形の段階では材料準備の段階において得られる板材を少なくとも一個の金型を用いて少なくとも一回のプレス成形を行なわせることにより、板材の第一表面において一個の不等厚構造を形成させる。フライス切削の段階では成形の段階において得られた板材の第二表面を切削することにより、一個のフェースを形成して一個のゴルフクラブヘッドのフェース板を獲得する。   In order to achieve the above object, a method for manufacturing a face plate of a golf club head according to the present invention includes a material preparation step, a forming step, and a milling step. In the material preparation stage, a plate material to be processed is prepared. The plate includes one opposing first surface and one opposing second surface. In the molding stage, the plate material obtained in the material preparation stage is subjected to at least one press molding using at least one mold, thereby forming one unequal thickness structure on the first surface of the plate material. In the milling step, the second surface of the plate material obtained in the forming step is cut to form one face to obtain one face plate for one golf club head.

また、成形の段階には粗型成形の段階と細型成形の段階が含まれ、粗型成形の段階では比較的簡単な曲面を有する一個の金型を用いて板材を成形し、かつ細型成形の段階では比較的精密な曲面を有する一個の金型を用いて再び板材を成形することもできる。また、板材がフライス切削の段階を経た後、他に引き続き成形の段階を行い、円弧状曲面を有する金型を用いて板材のフェースを成形することにより、フェースは円弧形に形成することもできる。また、板材が成形の段階を経た後、他に引き続き表面清浄の段階を行い、板材の表面に対してサンドブラストを行うことにより、板材の表面に生成される酸化物および／または不純物を除去することもできる。また、フェースの曲率の半径は１６０ミリから６００ミリまでであることもできる。また、成形の段階において、板材をプレス成形する前に、予め板材のそれぞれの表面において一個の抗酸化層を形成することもできる。また、成形の段階において、板材のフェースを成形する前に、予め板材のそれぞれの表面において一個の抗酸化層を形成することもできる。   The molding stage includes a rough molding stage and a thin molding stage. In the rough molding stage, a plate material is molded using a single mold having a relatively simple curved surface, and the thin molding process is performed. In the stage, the plate material can be formed again using a single mold having a relatively precise curved surface. In addition, after the plate material has undergone the milling step, the subsequent molding step is performed, and the face is formed into an arc shape by forming the face of the plate material using a mold having an arcuate curved surface. it can. In addition, after the plate material has undergone the molding stage, the surface cleaning step is subsequently performed, and the surface of the plate material is sandblasted to remove oxides and / or impurities generated on the surface of the plate material. You can also. Further, the radius of curvature of the face can be from 160 mm to 600 mm. Further, in the forming stage, before the plate material is press-molded, one antioxidant layer can be formed in advance on each surface of the plate material. Further, in the forming stage, before forming the face of the plate material, one antioxidant layer can be formed in advance on each surface of the plate material.

本発明のゴルフクラブヘッドのフェース板の製造方法によれば、先にフェース板の一つの表面において不等厚構造を成形し、それからフェース板のもう一つの表面をフライス切削することにより、製造コストを抑えるとともに、生産能力を高めることができるという利点がある。   According to the method for manufacturing the face plate of the golf club head of the present invention, the unequal thickness structure is first formed on one surface of the face plate, and then the other surface of the face plate is milled. There is an advantage that the production capacity can be increased.

本発明の実施の形態について、以下、図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は本発明のゴルフクラブヘッドのフェース板の製造方法の流れ図である。図１を参照すると、本発明のゴルフクラブヘッドのフェース板の製造方法は主に一個の材料準備の段階Ｓ１、一個の成形の段階Ｓ２および一個のフライス切削の段階Ｓ３を含む。成形の段階Ｓ２において、金型を用いて材料準備の段階Ｓ１において得られる板材１の一つの表面を不等厚構造１３にプレス成形し、さらにフライス切削の段階Ｓ３において板材１のもう一つの表面に対してフライス切削を行うことにより、不等厚構造１３を有するフェース板を成形する。   FIG. 1 is a flowchart of a method for manufacturing a face plate of a golf club head according to the present invention. Referring to FIG. 1, the method of manufacturing a face plate of a golf club head according to the present invention mainly includes one material preparation step S1, one molding step S2, and one milling step S3. In the forming step S2, one surface of the plate material 1 obtained in the material preparation step S1 is press-molded into a non-uniform thickness structure 13 using a mold, and further in the milling step S3, the other surface of the plate material 1 is pressed. The face plate having the unequal thickness structure 13 is formed by performing milling.

図２ａは本発明のゴルフクラブヘッドのフェース板の製造過程の説明図（一）である。図１、２ａを参照すると、本発明の材料準備の段階Ｓ１においては加工処理を行おうとする板材１を準備する。さらに詳しく言えば、本実施例において一個の切削装置（例えば、レーザー切断機械）を用いて一個の基材を完成品の外縁の輪郭に近い複数個の板材１に切断して、後続の段階における製造工程に提供することができる。   FIG. 2A is an explanatory view (1) of a manufacturing process of a face plate of a golf club head according to the present invention. Referring to FIGS. 1 and 2a, in the material preparation stage S1 of the present invention, a plate material 1 to be processed is prepared. More specifically, in this embodiment, a single cutting device (for example, a laser cutting machine) is used to cut a single base material into a plurality of plate members 1 that are close to the contour of the outer edge of the finished product. It can be provided to the manufacturing process.

板材１には相対する一個の第一表面１１と一個の第二表面１２が含まれる。板材１の材料は、好ましくは、比較的高い弾性変形能力または振動吸収能力を有する金属部材、例えば、炭素鋼、ステンレス（例えば、１７−４ＰＨステンレス）、合金鋼、ニッケル合金、鋳鉄、超合金鋼、フェロ−マンガン−アルミ合金、チタン合金、銅合金、アルミ合金、マグネシウム合金または上記金属材質の組合せからなることができる。   The plate 1 includes one opposing first surface 11 and one second surface 12. The material of the plate 1 is preferably a metal member having a relatively high elastic deformation ability or vibration absorption ability, such as carbon steel, stainless steel (for example, 17-4PH stainless steel), alloy steel, nickel alloy, cast iron, superalloy steel. , Ferro-manganese-aluminum alloy, titanium alloy, copper alloy, aluminum alloy, magnesium alloy or a combination of the above metal materials.

図２ｂは本発明のゴルフクラブヘッドのフェース板の製造過程の説明図（二）である。図１、２ｂを参照すると、本発明の成形の段階Ｓ２においては、材料準備の段階Ｓ１において得られた板材１を金型の中に置き入れ、少なくとも一回のプレスまたは鍛造の方法を経て、不等厚構造１３を有する板材１を獲得する。本実施例においては鍛造の方法を用いて説明を行い、かつ成形の段階Ｓ２には一個の粗型成形の段階Ｓ２１と一個の細型成形の段階Ｓ２２が含まれる。   FIG. 2B is an explanatory view (2) of the manufacturing process of the face plate of the golf club head of the present invention. Referring to FIGS. 1 and 2b, in the molding step S2 of the present invention, the plate material 1 obtained in the material preparation step S1 is placed in a mold, and after at least one press or forging method, The plate material 1 having the unequal thickness structure 13 is obtained. In this embodiment, description will be made using a forging method, and the forming step S2 includes one rough forming step S21 and one thin forming step S22.

粗型成形の段階Ｓ２１においては、比較的簡単な曲面を有する一個の金型を用いて板材１を成形する。さらに詳しく言えば、板材１と比較的簡単な曲面を有する金型を加熱し、それから板材１を上記金型の中に置き入れ、上記金型を用いて板材１に対してプレス成形を行うことにより、湾曲状の板材１を獲得し、さらに板材１の第一表面１１において不等厚構造１３を初期的に成形することができる。その中、板材１の材料の違いによって板材１と金型に設定される加熱温度が異なることは、従来の技術分野に属する普通の技術者には容易に理解できるものであり、かつ上記加熱温度は好ましくは板材１の結晶の溶解温度を超えないことである。   In the rough molding step S21, the plate material 1 is molded using a single mold having a relatively simple curved surface. More specifically, heating the plate material 1 and a mold having a relatively simple curved surface, and then placing the plate material 1 in the mold, and press-molding the plate material 1 using the mold. Thus, the curved plate member 1 can be obtained, and the unequal thickness structure 13 can be initially formed on the first surface 11 of the plate member 1. Among them, it can be easily understood by a normal engineer belonging to the conventional technical field that the heating temperature set for the plate 1 and the mold differs depending on the material of the plate 1. Preferably does not exceed the melting temperature of the crystals of the plate 1.

その他に、板材１を加熱し成形する前に、板材１の特性によって選択的に板材１の表面において一層の抗酸化層を形成することにより、板材１の加熱および成形時において酸化物が生じるのを減らすことができる。すなわち、板材１が酸化し易い金属（例えば、チタン金属）からなる場合、好ましくは板材１の表面に抗酸化層を形成する。それとは逆に、板材１が酸化し難い金属（例えば、鋼）からなる場合、板材１の表面に抗酸化層を形成する必要性はない。本実施例において、選択的に抗酸化剤をそれぞれの板材１に噴き付け、さらに上記抗酸化剤が乾燥してから上記抗酸化層を形成することができる。   In addition, by forming a single antioxidant layer on the surface of the plate 1 selectively according to the properties of the plate 1 before heating and forming the plate 1, oxides are generated during heating and forming of the plate 1. Can be reduced. That is, when the plate 1 is made of a metal that is easily oxidized (for example, titanium metal), an antioxidant layer is preferably formed on the surface of the plate 1. On the contrary, when the plate 1 is made of a metal that is difficult to oxidize (for example, steel), there is no need to form an antioxidant layer on the surface of the plate 1. In this embodiment, the antioxidant layer can be formed after the antioxidant is selectively sprayed on each plate 1 and the antioxidant is dried.

同様に、板材１が酸化し易い金属からなる場合、後続の細型成形の段階Ｓ２２を行う前に、好ましくは先に粗型成形の段階Ｓ２１で得られる板材１の表面において再び一層の抗酸化剤を被覆することにより、板材１の変形する場所においても抗酸化の効果を有するように形成される。それに対して、板材１が酸化し難い金属からなる場合、粗型成形の段階Ｓ２１で得られる板材１の表面に再び一層の抗酸化層を形成する必要性はない。   Similarly, when the plate 1 is made of a metal that is easily oxidized, a further antioxidant is preferably formed again on the surface of the plate 1 obtained in the rough forming step S21 before the subsequent thin forming step S22. By covering the plate, the plate material 1 is formed so as to have an antioxidative effect even at a place where the plate 1 is deformed. On the other hand, when the plate 1 is made of a metal that is difficult to oxidize, there is no need to form another antioxidant layer on the surface of the plate 1 obtained in the rough molding step S21.

図２ｃは本発明のゴルフクラブヘッドのフェース板の製造過程の説明図（三）である。図１、２ｃを参照すると、細型成形の段階Ｓ２２においては比較的精密な曲面を有する一個の金型を用いて板材１を成形する。さらに詳しく言えば、粗型成形の段階Ｓ２１において得られる板材１は生産ラインで流れる時、温度が下がる現象を生じ、甚だしくは室温まで冷却されるため、細型成形の段階Ｓ２２を行う場合、先ず板材１と比較的精密な曲面を有する金型に対して加熱を行わなければならず、かつその加熱温度は板材１の結晶の溶解温度を超えないことを原則とする。それから、板材１を上記金型の中に置き入れ、上記金型によって板材１に対してプレス成形を行うことにより、不等厚構造１３を有する板材１を獲得することができる。この時、板材１の第一表面１１の上の不等厚構造１３は既に予め設けられる形態と同じように形成される。   FIG. 2 c is an explanatory view (3) of the manufacturing process of the face plate of the golf club head of the present invention. Referring to FIGS. 1 and 2c, in the thin molding step S22, the plate material 1 is molded using a single mold having a relatively precise curved surface. More specifically, since the plate material 1 obtained in the rough molding step S21 has a phenomenon that the temperature is lowered when flowing in the production line and is cooled down to room temperature, when performing the thin molding step S22, first, the plate material In principle, a mold having a relatively precise curved surface with 1 must be heated, and the heating temperature does not exceed the melting temperature of the crystals of the plate 1 in principle. Then, the plate material 1 having the unequal thickness structure 13 can be obtained by placing the plate material 1 in the mold and press-molding the plate material 1 with the mold. At this time, the unequal thickness structure 13 on the first surface 11 of the plate 1 is formed in the same manner as that already provided.

図２ｄは本発明のゴルフクラブヘッドのフェース板の製造過程の説明図（四）である。図１、２ｄを参照すると、本発明のフライス切削の段階Ｓ３においては一台の工作機械によって板材１の第二表面１２をフライス切削し修整することにより、一個のフェース１４を形成する。本実施例において、細型成形の段階Ｓ２２で得られる板材１を適当な温度（例えば、室温）まで下げた後、選択的にコンピューターのデータを使用してフライス盤を制御し、さらに適当な刃具と合わせて板材１の第二表面１２を平らにフライス切削することにより、フェース１４を形成することができる。   FIG. 2D is an explanatory diagram (4) of the process for producing the face plate of the golf club head of the present invention. Referring to FIGS. 1 and 2D, in the milling step S3 of the present invention, one face 14 is formed by milling and modifying the second surface 12 of the plate 1 with a single machine tool. In this embodiment, after the plate material 1 obtained in the thin molding step S22 is lowered to a suitable temperature (for example, room temperature), the milling machine is selectively controlled using computer data, and further combined with a suitable cutting tool. Then, the face 14 can be formed by milling the second surface 12 of the plate 1 flatly.

本発明においては成形の段階Ｓ２を経て直接板材１に不等厚構造１３を形成させることができ、さらにフライス切削の段階Ｓ３を経て迅速に板材１のフェース１４を平らにフライス切削することにより、本発明においては切削すべき板材１の廃材を大幅に減らすことができるため、原料のコストを節約することができるだけではなく、フライス盤の負担を軽く減らすことができる。加えて、刃具の消耗率を低く抑えることができ、さらに３Ｄの切削の代わりに２Ｄの切削によって加工時間（約３分間で一個のフェース板の成形の加工を完成する。）とコストを減らすことができるため、生産能力を有効に高めることができる。   In the present invention, the unequal thickness structure 13 can be directly formed on the plate 1 through the forming step S2, and further, the face 14 of the plate 1 can be quickly and flatly milled through the milling step S3. In the present invention, since the waste material of the plate material 1 to be cut can be greatly reduced, not only the cost of the raw material can be saved, but also the burden on the milling machine can be reduced lightly. In addition, the wear rate of the cutting tool can be kept low, and further, the processing time (the processing for forming one face plate is completed in about 3 minutes) and cost are reduced by 2D cutting instead of 3D cutting. Production capacity can be effectively increased.

図２ｅは本発明のゴルフクラブヘッドのフェース板の製造過程の説明図（五）である。図１、２ｅを参照すると、板材１はフライス切削の段階Ｓ３の処理を経た後、引き続き一個の後処理の段階Ｓ４を行うことができ、板材１に対して修整を行うことにより、品質のよいゴルフクラブヘッドのフェース板の完成品を獲得することができる。さらに詳しく言えば、後処理の段階Ｓ４には一個の成形の段階Ｓ４１と一個の表面清浄の段階Ｓ４２が含まれる。   FIG. 2E is an explanatory view (5) of the manufacturing process of the face plate of the golf club head of the present invention. Referring to FIGS. 1 and 2e, after the plate material 1 has undergone the processing of the milling step S3, the post-processing step S4 can be subsequently performed. A finished product of the face plate of the golf club head can be obtained. More specifically, the post-processing stage S4 includes one molding stage S41 and one surface cleaning stage S42.

成形の段階Ｓ４１においては一個の円弧状曲面を有する金型を用いて板材１のフェース１４を成形することにより、フェース１４は適当な円弧を有するように形成されるため、ゴルフクラブヘッドに結合することができる。本実施例において、フライス切削の段階Ｓ３で得られる板材１と円弧状曲面を有する金型を加熱し、さらに板材１を上記金型の中に置き入れ、上記金型を用いて板材１のフェース１４に対して成形を行うことにより、フェース１４は円弧状に形成され、かつフェース１４の曲率の半径は好ましくは１６０ミリから６００ミリまでである。   In the forming step S41, the face 14 of the plate member 1 is formed by using a mold having a single arcuate curved surface, so that the face 14 is formed to have an appropriate arc, and is thus coupled to the golf club head. be able to. In this embodiment, the plate material 1 obtained in the milling step S3 and the mold having an arcuate curved surface are heated, the plate material 1 is further placed in the mold, and the face of the plate material 1 is used by using the mold. By forming the face 14, the face 14 is formed in an arc shape, and the radius of curvature of the face 14 is preferably 160 mm to 600 mm.

その中、板材１の第二表面１２の上で一部分の表面はフライス切削の段階Ｓ３において切削し除去され、かつその部位の抗酸化層も合わせて除去されるため、酸化し易い金属によって製造された板材１に対し、成形の段階Ｓ４１を行う前に、新たに板材１の表面において抗酸化剤を噴き付けることにより、板材１の表面のそれぞれの部位に全て一層の抗酸化剤が被覆されるため、抗酸化の効果を有するように形成されるのが好ましい。   Among them, a part of the surface on the second surface 12 of the plate 1 is cut and removed in the milling step S3, and the antioxidant layer at the part is also removed, so that it is made of a metal that is easily oxidized. Before the forming step S41 is performed on the plate material 1, a single layer of antioxidant is coated on each part of the surface of the plate material 1 by newly spraying an antioxidant on the surface of the plate material 1. Therefore, it is preferably formed so as to have an antioxidant effect.

板材１は成形の段階Ｓ４１の処理を経た後、表面清浄の段階Ｓ４２を行うことができ、けい砂、酸化アルミニウム、砂鉄、アルミ粒子または鉄粒子などの顆粒をもって、板材１の表面に対してサンドブラストを行って、板材１の表面に生成される酸化物および／または不純物を除去することにより、本発明のゴルフクラブヘッドのフェース板の製造を完成することができる。その他に、必要に応じて、レーザー彫刻などの方法によって板材１の表面（例えば、フェース１４）に型番、文字または商標などの図案を彫刻することにより、製品の識別性を高めることができる。   After the plate material 1 has undergone the processing of the forming step S41, the surface cleaning step S42 can be performed, and sandblasting is performed on the surface of the plate material 1 with granules such as silica sand, aluminum oxide, iron sand, aluminum particles or iron particles. The production of the face plate of the golf club head of the present invention can be completed by removing oxides and / or impurities generated on the surface of the plate material 1. In addition, the identification of the product can be enhanced by engraving a design such as a model number, letters, or a trademark on the surface (for example, the face 14) of the plate 1 by a method such as laser engraving as necessary.

上述したように、本発明のゴルフクラブヘッドのフェース板の製造方法によれば、先にフェース板の第一表面に不等厚構造を成形させ、再びフェース板の第二表面をフライス切削し修整することにより、切削される板材の廃材を大幅に減らすことができるため、フライス盤の刃具の消耗率を低く抑えることができるとともに、加工の時間を短縮することができ、さらに製造コストを節約して生産能力の効果を高めることができる。   As described above, according to the method for manufacturing the face plate of the golf club head of the present invention, the unequal thickness structure is first formed on the first surface of the face plate, and the second surface of the face plate is again milled and repaired. As a result, the scrap material of the plate material to be cut can be greatly reduced, so that the consumption rate of the cutting tool of the milling machine can be kept low, the processing time can be shortened, and the manufacturing cost can be saved. The effect of production capacity can be increased.

本発明は、その精神および必須の特徴事項から逸脱することなく他のやり方で実施することができる。従って、本明細書に記載した好ましい実施形態は例示のなものであり、限定を意図するものではない。   The present invention may be implemented in other ways without departing from the spirit and essential characteristics thereof.
