Abstract
A method of processing the surface of a metallic rod, wherein films (2, 22 and 32) are applied onto portions other than the shape where grooves are to be formed on the surface of the rod, the surfaces of the rods (1, 21 and 31) which are not coated are dissolved and processed by chemical polishing or etching, whereby patterns of very shallow grooves (6, 24 and 34) are formed on the surface of the rod, so that making of grooves on the surface of a very heavy rod, a long rod and a curved rod, which have been considered difficult by the conventional machining, can be easily and highly accurately carried out. Furthermore, after the making of the grooves, the surface of a rod (41) excluding the groove portions and recessed portions (43) is plated in a state (42) of being coated by resist films and screens, whereby the grooves and the recessed portions (43) are plated (44), and thereafter, the coating films (42) are removed by buffing (45) and the like and the plated surface is finished, thus effectively plating the grooves and the recessed portions.

或い は異材を埋め込んだ形の も のを作る こ と がで き る 。 ま た必要に応 じて第 1 3図（a) , (b)に示す よ う に， 第： [ 2図 (a) , (b)の ロ ッ ド表面 4 5に， 4 6で示 し た よ う に メ ツ キ を ほ ど こ して も よ い。 こ の よ う にす る と 溝部や凹部の模様の 都分 4 4は二重メ ツ キ と な る ので ， 特に硬質 ク ロ ム メ ツ キ 等におい て は， メ ツ キ のつ き に く い溝部の メ ツ キ 防鎗効 果を一層 向上 させ る こ とがで き る 。 なお第 1 3図 (b) は第 1 3 図（a)の L 一 L 線に沿 う 断面図で あ る 。 産業上の利用 可能性 As described above, a pattern of dissimilar material is made on the surface of the mouth: Or you can make things with different materials embedded. If necessary, as shown in Figs. 13 (a) and 13 (b), see Fig. 13 [a] and [b]. As you can see, you can do the tricks. In this case, the pattern of the groove and the concave portion is double-plated. Therefore, particularly in the case of hard chrome plating, it is difficult to use the plating. It is possible to further improve the anti-spear effect of the groove in the groove. FIG. 13 (b) is a cross-sectional view taken along line L-L of FIG. 13 (a). Industrial applicability
こ の発明 は以上詳述 し た よ う に し て成 る の で， 従来の 機械加工で は困難で あ っ た重量物の 口 ッ ドゃ長い 口 ッ K f 曲 っ た 口 ッ ド な どの表面に ご く 浅い模様加工や溝加工を 容易に高精度で， しか も安価に実施で き る と い う 大き い 効果を奏す る も の であ る 。 This invention than Ru formed in the cormorants it has been described in detail above, mouth head of what was Tsu mouth head Ya long mouth Tsu K f songs of weight was Tsu Oh difficult with conventional machining This has the great effect that very shallow pattern and groove machining on the surface can be easily performed with high precision and at low cost.
さ ら に ま た こ の発明 は 口 ッ ド の溝部や凹部を先 に メ ッ キ す る こ と に よ っ て， .元来メ ツ キ がつき に く い と さ れて い る 溝や凹部を効果的に メ ツ キ で き る 。 In addition, the present invention is characterized in that a groove or a concave portion of a mouth is firstly plated, so that a groove or a groove which is originally difficult to be attached is formed. The recess can be effectively plated.
ま た ロ ッ ド表面 と溝部メ ツ キ 表面の高 さ を 同一 と して い る ので， メ ツ キ →研磨→メ ツ キ—研磨を何度も く り 返 す こ と な しに加工で き る。 Also, since the height of the rod surface and that of the grooved surface are the same, it is possible to perform machining without repeating plating → polishing → plating-polishing many times. Wear.
さ ら に こ の発明で は溝部メ ツ キ の後に バフ 研磨す る こ と に よ り ， 被覆膜を除去す る と 共に メ ツ キ表面を研磨仕 上す る こ と がで き ， ま た必要に応 じ て研磨後 さ ら に メ ッ キ す る こ と に よ っ て溝部の メ ツ キ を二重メ ツ キ と する こ と が可能 と な り ， 特に硬質 ク ロ ム メ ツ キ にお いて防錡効
果が増大する。 Further, in the present invention, the buffing is performed after the groove feature, so that the coating film can be removed and the finish surface can be polished. If necessary, it is possible to make the groove plating a double plating by polishing it further after polishing, especially hard chrome plating. Effective in g Fruit increases.
こ のよ う に こ の発明 は加工工数を低減 し， しかも メ ッ キ品質の高い 口 ドの溝加工方法を提供する こ と がで き る。
As described above, the present invention can provide a method of forming a groove with a high finish quality while reducing the number of processing steps.
