【発明の詳細な説明】
（産業上の利用分野）
この発明は板ガラスの周縁の研削やその他諸祠料の研削
に用いられる研削砥石に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a grinding wheel used for grinding the periphery of plate glass and other various abrasive materials.
（従来の技術）
自動車窓ガラスなどの周縁加工等に持ちいられる砥石と
しては、第２図に示す様な円板状台金１の外周端２に、
ダイヤモンドや（ＢＮ砥粒をボンドした超砥粒層３を形
成したものが知られている。(Prior Art) As a grindstone used for processing the peripheral edge of automobile window glass, etc., a grindstone is attached to the outer peripheral edge 2 of a disk-shaped base metal 1 as shown in FIG.
It is known that a superabrasive layer 3 is formed by bonding diamond or BN abrasive grains.
そしてこれら砥石は、第３図に示す様に台金１の外周に
、凸部６を有する外型５を設置し、台金１の外周と外型
５との間に砥粒と青銅粉等のボンド材との混合粉を装入
し、押しリング７で押圧した状態で８００〜１０００°
Ｃで焼結して製造されている。As shown in FIG. 3, these grindstones are equipped with an outer mold 5 having a convex portion 6 on the outer periphery of the base metal 1, and abrasive grains and bronze powder etc. are placed between the outer periphery of the base metal 1 and the outer mold 5. Charge the mixed powder with the bonding material and press it with the push ring 7 at an angle of 800 to 1000°.
It is manufactured by sintering with C.
（発明が解決しようとする課題）
従来の製造法によっては、凸部６を有する外型！
〆が必要であり、この凸部により焼結後件型を抜きとる
ことが出来ない。(Problem to be Solved by the Invention) Depending on the conventional manufacturing method, an outer mold having a convex portion 6! A finish is necessary, and the sintered mold cannot be removed due to this convex portion.
従って、外型は分解するとか、切除するとかの手段が必
要となり、また砥面の凹部形状に沿う外型が必要となる
短所がある。Therefore, the outer mold requires means for disassembling or cutting it out, and there is also the disadvantage that the outer mold needs to conform to the shape of the recesses on the abrasive surface.
（課題を解決するための手段）
外型をフラットにして凸部を設けない。従って、外型は
分解しないでも抜くことが出来る。砥面の凹部の形成は
レーザー光によって行い、凹部形状は自在に形成できる
。(Means for solving the problem) The outer mold is made flat and no convex parts are provided. Therefore, the outer mold can be removed without disassembly. The recesses on the abrasive surface are formed using laser light, and the shape of the recesses can be formed freely.
（実施例）
この台金を、取付孔４を中心として回転しながら、（！
１部を形成すべき砥面にレーザー光を当てた。この条件
は凹部の形状、大きさに従いレーザー光は５００ｗ 〜
２ ｋｗｓ台金の回転は１１０−２０ＯＲＰ、台金の送
りは１〜１００ｍｍ／ｗｉｎの範囲の中から適当に選択
する。(Example) While rotating this base metal around the mounting hole 4, (!
A laser beam was applied to the abrasive surface on which the first part was to be formed. This condition is based on the shape and size of the recess, and the laser beam is 500W ~
2 kws The rotation of the base metal is 110-20 ORP, and the feed rate of the base metal is appropriately selected from the range of 1 to 100 mm/win.
尚照射する方向は第１図Ａの様に、細心に向って当て、
凹部の浅い部分は深い部分より、台金の回転、送りを相
対的に早くして行い、第１図Ｂの様に軸心に平行に当て
る場合は、照射点が、凹部形状に沿って、往復動をせし
める様に設定して行う。The direction of irradiation is as shown in Figure 1 A, and the
The shallow part of the recess is rotated and fed relatively faster than the deep part, and when applying parallel to the axis as shown in Figure 1B, the irradiation point follows the shape of the recess. This is done by setting it to force reciprocating motion.
