【発明の詳細な説明】
本発明は研削砥石のフォーミングドレッサに関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a forming dresser for a grinding wheel.
従来、ダイヤ砥粒を電鋳法で埋め込んだ成形フォーミン
グドレッサーを用いて砥石を成形する場合、ダイヤ粒度
の細かいものを選んだ場合にはその成形精度は高まるが
、成形された砥石の切れ味は劣り、他方ダイヤ粒度の粗
いものを選んだ場合には、砥石の切れ味は良いが成形精
度が劣るという難点があった。Conventionally, when forming a whetstone using a forming dresser in which diamond abrasive grains are embedded using the electroforming method, if a diamond abrasive grain size is selected, the forming precision increases, but the sharpness of the formed whetstone is inferior. On the other hand, when a diamond with a coarse grain size is selected, the sharpness of the whetstone is good, but the forming precision is poor.
本発明はかかる従来方式の難点を解消し、すぐれた切れ
味で、かつ成形精度の高い成形砥石が実現出来る新規な
構成のフォーミンク下しツサを提供することを目的とす
る。It is an object of the present invention to provide a forming grinder with a novel structure that eliminates the drawbacks of the conventional method and can realize a forming grindstone with excellent sharpness and high forming precision.
上記目的を達成するため本発明は、切り込みを主とする
部位に１１０／１２〜＃２０／２３メツシユの大粒ダイ
ヤを電鋳法で埋め込み、かつ成形精度を要する部位には
＃４０／６０〜＃］００／１２０メツシユの細粒ダイヤ
を電鋳法で埋め込んであることを特徴とするものである
。In order to achieve the above object, the present invention uses electroforming to embed large diamonds of 110/12 to #20/23 mesh in the parts where the notches are the main part, and #40/60 to #4 in the parts that require forming precision. ]00/120 mesh fine diamonds are embedded by electroforming.
以下本発明を実施例に基づいて説明する。The present invention will be explained below based on examples.
テーブル上に固着されたワークをフォーミングドレッサ
ーにより成形された砥石を用いて加工する場合例えば研
削砥石の先端部は主としてワークの切り込みを行うため
切れ味が良いことが要求され、他方研削砥石の成形部は
切れ味よりも成形精度が要求される。When processing a workpiece fixed on a table using a whetstone formed by a forming dresser, for example, the tip of the grinding wheel is required to be sharp because it mainly cuts into the workpiece, while the formed part of the grinding wheel is required to be sharp. Forming precision is required more than sharpness.
このため、本発明フォーミングドレッサーは、研削砥石

下の微小成形面部には＃４０／６０〜＃１００／１２０
メツシユの細粒ダイヤを電鋳法により埋め込んである。For this reason, the forming dresser of the present invention has a part corresponding to the part of the grinding wheel that mainly makes cuts, for example, in the case of a grinding wheel for a magnetic head, the bottom surface of the dresser and a large inclined surface having an angle of 75° to 90° with the bottom surface. =#=1.
A large diamond of 0/12~=#=20/23 mesh is embedded by electroforming to form a part of the grinding wheel whose forming precision is the main focus, such as a micro-formed surface part of about 1 mm or less in the case of a grinding wheel for a magnetic head. #40/60~#100/120
Fine mesh diamonds are embedded using the electroforming method.
かかる構成の本発明フォーミングドレッサーにより、研
削砥石を成形すれば、切れ味が良く、かつ成形精度に優
れた加工が出来るため、極めて有用である。If a grinding wheel is formed using the forming dresser of the present invention having such a configuration, it is extremely useful because it can be processed with good sharpness and excellent forming accuracy.
尚、上記説明ではブロック状のフォーミングドレッサに
ついて述べたが、本発明は回転体状のロータリードレッ
サーであっても適用できることは勿論である。In the above description, a block-shaped forming dresser has been described, but it goes without saying that the present invention can also be applied to a rotating body-shaped rotary dresser.
