て゛あった。[Prior art] Conventionally, for example, ε11 was used to grind a cup-shaped grindstone.
When performing I-machining, as the length of the contact arc between the grinding wheel and the workpiece increases, considerable grinding heat is generated, so it is essential to reliably supply the grinding fluid to the J-point. ing. On the contrary, such devices and methods have not been established at present, and in the current processing method, as shown in FIG. Since processing is performed while moving the grinding fluid relatively and supplying the grinding fluid from the external nozzle 21, the grinding fluid can be reliably supplied to the processing location by blocking the air layer generated as the cup-shaped grindstone 22 rotates. It was difficult.

Since machining fluid can be supplied to the machine, it is possible to improve machining efficiency and machining accuracy, reduce tool tension, and prevent damage to the rigid material.
また、ノズル部をボス部の先端中心に設けることにより
、加工箇所に平均的に加工液を供給することができ、よ
り加工能率を向上させることができる。Further, by providing the nozzle portion at the center of the tip of the boss portion, the machining liquid can be evenly supplied to the machining location, and machining efficiency can be further improved.
また、本体から突出して形成された突出部に受液口を設
け、加工液供給［１に嵌合するようにしたので、加工液
を供給する特別の装置を必要としない。Further, since the liquid receiving port is provided in the protrusion formed to protrude from the main body and is fitted into the machining liquid supply [1], a special device for supplying the machining liquid is not required.
更に、本体の外周に相互に回転可能に装着された加工液
供給部材の加工液供給口に連通ずるように、受液口を本
体外側に開口されているので、主軸に加工液通路を形成
する必要がない。Furthermore, since the liquid receiving port is opened on the outside of the main body so as to communicate with the machining liquid supply port of the machining liquid supply member that is rotatably mounted on the outer periphery of the main body, a machining liquid passage is formed in the main shaft. There's no need.
そして、工具装着部へのアーμの装着に基いて加工液通
路口と受液口とを連通すると共に、アーμの未装着時に
は加工液通路口を外部に対して封止するようにしたので
、アーμの取外しにより加工液が外部へ漏れることがな
く、工具交換時の操作性を向上することができる。Then, the machining fluid passage port and the liquid receiving port are communicated based on the installation of the arμ to the tool mounting portion, and the machining fluid passage port is sealed from the outside when the arμ is not installed. The machining fluid does not leak to the outside by removing the arμ, making it possible to improve the operability when changing tools.
