Abstract
An air driven tool for use in a machining center, the air driven tool including an adjustable speed regulator and a turbine. The turbine is driven by pressurized air directed thereto. The turbine is rotatable about an axis. A flow of the air is regulated by the adjustable speed regulator. The adjustable speed regulator includes a biasing member, an inclined annular surface, a regulator plate and a plurality of moveable bearings. The inclined annular surface has an angle relative to the axis. The plurality of movable bearings are positioned between the inclined annular surface and the regulator plate. The biasing member biases the inclined annular surface and/or the regulator plate toward each other.

An air driven tool for use in a machining center, the air driven tool, comprising:
- an adjustable speed regulator;
- and
- a turbine driven by pressurized air directed thereto, said turbine being rotatable about an axis, a flow of the air being regulated by said adjustable speed regulator, said adjustable speed regulator including:
- a biasing member;
- an inclined annular surface being at an angle relative to said axis;
- a regulator plate;
- and
- a plurality of movable bearings positioned between said inclined annular surface and said regulator plate, said biasing member biasing at least one of said inclined annular surface and said regulator plate toward each other.
A machining center, comprising:
- a tool head;
- and
- an air driven tool attachable to said tool head, said air driven tool including:
- an adjustable speed regulator;
- and
- a turbine driven by pressurized air directed thereto, said turbine being rotatable about an axis, a flow of the air being regulated by said adjustable speed regulator, said adjustable speed regulator including:
- a biasing member;
- an inclined annular surface being at an angle relative to said axis;
- a regulator plate;
- and
- a plurality of movable bearings positioned between said inclined annular surface and said regulator plate, said biasing member biasing at least one of said inclined annular surface and said regulator plate toward each other.
