Abstract
A machining device includes a tool with a rotational axis and porous material with an outer peripheral surface disposed about the rotational axis and adapted to machine a surface of a workpiece. The machining device further includes a fluid delivery device oriented relative to the tool to disperse fluid to contact the tool primarily at a location inboard from the outer peripheral surface of the tool such that dispersed fluid is capable of flowing through the porous material. The machining device provides a controlled radial discharge of fluid at a workpiece surface in use. Methods of machining a workpiece are also provided.

A machining device for machining a surface of a workpiece comprising:
- a) a tool including a rotational axis and porous material with an outer peripheral surface disposed about the rotational axis and adapted to machine a surface of a workpiece;
- and
- b) a fluid delivery device oriented relative to the tool to disperse fluid to contact the tool primarily at a location inboard from the outer peripheral surface of the tool such that dispersed fluid is capable of flowing through the porous material, wherein the machining device provides a controlled radial discharge of fluid at a workpiece surface in use.
A method of machining a workpiece comprising the steps of:
- a) providing a workpiece;
- b) providing a tool including a rotational axis and porous material with an outer peripheral surface disposed about the rotational axis;
- c) providing a fluid delivery device;
- d) dispersing fluid from the fluid delivery device such that the fluid contacts the tool primarily at a contact location inboard from the outer peripheral surface of the tool;
- e) rotating the tool about the rotational axis such that fluid flows through the porous material;
- and
- f) machining the workpiece with the outer peripheral surface of the tool at a machining zone, wherein a controlled radial discharge of fluid is provided at the machining zone.
