本発明はセラミックスを研削するためのダイヤモンドホ

４６２０号、６３−３１３４４号公報等参照）。また、
複雑形状のセラミックス製品の加工には、多軸制御の研
削盤を用いていた。Diamond wheels were widely used for grinding ceramic materials such as alumina and zirconia. This diamond wheel has a grinding surface formed by fixing diamond abrasive grains to the surface of a metal base such as a disc.While rotating the diamond wheel, the ceramic material is pressed against the grinding surface, thereby grinding the ceramic material. (For example, the special public
4620, 63-31344, etc.). Also,
A multi-axis controlled grinding machine was used to process ceramic products with complex shapes.

理が必要になるという問題点があった。However, such conventional grinding using a diamond wheel has not been able to reduce the surface roughness of the processed ceramics. Therefore, for example, in order to use zirconia ceramics for decorative members such as watch parts, there is a problem in that the surface must be finally smoothed by hand.
上記に鑑みて本発明は、１２００〜３００のダイヤモン

ダイヤモンドホイールを構成したものである。In view of the above, the present invention constitutes a diamond wheel by forming a rough ground surface to which 1200 to 300 diamond abrasive grains are fixed and a finished surface to which #600 to 800 diamond abrasive grains are fixed on the same surface. It is something.

ができる。While rotating this diamond wheel, the rough grinding surface first grinds the ceramic, and then the ceramic is moved to the finishing surface, making it possible to rough-process and finish ceramics with a single diamond wheel. In addition, #600-80 diamond abrasive grains are used for the rough grinding surface and #600-80 diamond abrasive grains are used for the finishing surface.
By using diamond abrasive grains of 0.0, the surface roughness of zirconia ceramics in particular can be made extremely good.
以下、本発明の実施例を図によって説明する。 Embodiments of the present invention will be described below with reference to the drawings.
第１図、第２図に示すダイヤモンドホイールｌは、円板

げ面３ａを形成しである。The diamond wheel l shown in FIGS. 1 and 2 is disc-shaped and is made up of a rough grinding substrate 2 placed on the outside and a finishing substrate 3 on the inside. Further, diamond abrasive grains having a relatively large grain size of #200 to 300 are fixed to the upper surface of the substrate 2 for rough grinding to form a rough grinding surface 2a, and the upper surface of the substrate 3 for finishing is #200 to #300. 600-800
The finished surface 3a is formed by fixing diamond abrasive grains having a relatively small particle size.

A diamond wheel 11 having a rough ground surface 12a and a finished surface 13a can also be used.
次に第１図、第２図に示すダイヤモンドホイールＩを使

−Ｂ間と同様に、２軸制御で切り込みを行いながら移動

移動させる。Next, a method of grinding ceramics using the diamond wheel I shown in FIGS. 1 and 2 will be explained. As shown in the plan view in Fig. 1, while rotating the diamond wheel 1, the ceramic to be ground is first cut by pressing the ceramic from point A to point B on the rough grinding surface 2a using two-axis control. Move while doing this. Next, change the direction 90 degrees from point B, and make the rough ground surface 2a and the finished surface 3.
It moves to the boundary point C of point a without making any cuts. Then, on the finished surface 3a, from point C to the dot is the above point A.
- B, the cutting is performed while moving under two-axis control, and finally, from the point to the point E, the cutting is performed without making a cutting.
以上の工程により、点Ａ−Ｂ間では、研削方向が徐々に
変化するため、研削性、表面粗さの向上という点で効果
的である。また、点Ａ−Ｂ問および点Ｃ−０間の切り込
みを伴う移動の後に、それぞれ点Ｂ−Ｃ間、点Ｅｌ−Ｅ
間で切り込みを伴わない移動を行うことによって、表面
粗さを向上させることができる。The above process gradually changes the grinding direction between points A and B, which is effective in terms of improving grindability and surface roughness. In addition, after moving with cuts between points A and B and between points C and 0, between points B and C and between points El and E, respectively.
Surface roughness can be improved by moving between the two without making cuts.
このように、ダイヤモンドホイール１には、荒研削面２
ａと仕上げ面３ａを同一面上に形威しであることから、
ひとつの工程で、極めて容易にセラミックスの荒加工と
仕上げ加工が可能となる。なお、荒研削面２ａと仕上げ
面３ａ間を移動させるときは、切り込みを行わないこと
から、第２図に示すように両者の間に隙間があってもよ
い。In this way, the diamond wheel 1 has a rough ground surface 2.
Since a and the finished surface 3a are on the same surface,
Rough machining and finishing of ceramics can be performed extremely easily in a single process. Note that when moving between the roughly ground surface 2a and the finished surface 3a, no cuts are made, so there may be a gap between them as shown in FIG. 2.
また、本発明のダイヤモンドホイールにおいて、２種類

Therefore, as shown in Table 1, zirconia ceramics were ground by varying the size of the diamond abrasive grains on the roughly ground surface and the finished surface, and the surface roughness after grinding was compared.
