Abstract
A small hole electric discharge machine drill is provided with a depth-specific processor and a tiltable unit operable in fluid. The turntable unit includes a first axis with a first center of rotation and a second tilting axis with a second center of rotation. The turntable unit is provided inside a work tank that may be filled with fluid. The small hole electric discharge machine drill includes an electrode for small hole processing.
Claims9
A small hole electric discharge machine drill comprising:
- a turntable having rotation axes of a first axis, of which a center of rotation is defined as a shaft center parallel to a processing axis, and a second axis, of which a center of rotation is defined as a shaft center orthogonal to the first axis,
- wherein the turntable is provided inside a work tank for filling a working fluid therein;
- and
- a fluid level controller for controlling a fluid level of the working fluid inside the work tank in a level slightly higher than a surface of a workpiece.
A small hole electric discharge machine drill comprising:
- a drilling electrode configured to be movable along a processing axis of the small hole electric discharge machine drill, and
- a turntable having rotation axes of a first axis, of which a center of rotation is defined as a shaft center parallel to the processing axis, and a second axis, of which a center of rotation is defined as a shaft center orthogonal to the first axis,
- wherein the turntable is provided inside a work tank configured to be filled with a working fluid.
A small hole electric discharge machine drill comprising:
- a turntable having rotation axes of a first axis, of which a center of rotation is defined as a shaft center parallel to a processing axis, and a second axis, of which a center of rotation is defined as a shaft center orthogonal to the first axis,
- wherein the turntable is provided inside a work tank for filling a working fluid therein, and
- wherein the turntable is disposed rotatably on one end inside the work tank of a second axis rotating shaft which extends from an outside of the work tank to an inside thereof,
- the second axis rotating shaft is provided with a blind hole which has an opening outside the work tank and extends to an end portion inside the work tank,
- a first axis drive motor is provided outside the work tank via the blind hole for rotating the turntable, and
- a second axis drive motor is provided outside the work tank for driving the second axis rotating shaft.
