Abstract
An Electro Chemical Grinding (ECG) quill includes a tool manufactured of a porous tool material having a multitude of pores. An ECG electrolyte is communicated through a hollow tool shank for communication through the porous tool material to manufacture a slot.
Claims20
An Electro Chemical Grinding (ECG) quill comprising:
- a shaft defined along an axis of rotation;
- and
- a tool mounted to said shaft, said tool manufactured of a porous tool material having a multitude of pores, disposed throughout the porous tool material, which extend from said shaft to an outer surface, said tool symmetrical defined about said axis of rotation.
An Electro Chemical Grinding (ECG) quill comprising:
- a shaft defined along an axis of rotation, said shaft comprises a hollow shank which defines a multiple of apertures transverse to said axis;
- and
- a tool mounted to said shaft, said tool manufactured of a porous tool material having a multitude of pores, wherein the multitude of pores are randomly arranged, in fluid communication with said hollow shank through said multiple of apertures, said tool symmetrical defined about said axis of rotation.
A method of machining a slot comprising:
- communicating an Electro Chemical Grinding (ECG) electrolyte through a hollow tool shank defined along an axis of rotation for communication through a tool symmetrical defined about the axis of rotation, the tool manufactured of a porous tool material as said tool is rotated about said axis of rotation.
