Abstract
A brush cutter adapted to be driven in rotary motion by a conventional machine tool. The brush cutter includes an annular wall having a cylindrical outer surface defining a longitudinal center axis. Front and rear faces are connected to opposing ends of the cylindrical outer surface. An arbor bore and a counterbore are concentrically disposed and coaxially aligned with the center axis. A plurality of brush assemblies are received within a plurality of circumferentially spaced axial and radial receiving bores. The axial receiving bores extend axially inwardly from the front face and the radial receiving bores extend radially inwardly from the cylindrical outer surface.
Claims20
A cutter for being driven in rotation by a spindle, said cutter including:
- a housing including an annular wall having a cylindrical outer surface and defining a longitudinal center axis, a front face connected to said outer surface, a rear face connected to said outer surface and positioned in spaced relation to said front face by said annular wall, a cylindrical inner surface defining an arbor bore extending axially inwardly from said rear face towards said front face and coaxially aligned along said center axis, a cylindrical intermediate surface defining a counterbore extending from said front face towards said rear face and coaxially aligned along said center axis, said counterbore in communication with said arbor bore, a lock shoulder defined between said arbor bore and said counterbore, a rotation registration device supported by said rear face, a plurality of circumferentially spaced axial receiving bores extending substantially axially inwardly from said front face towards said rear. face, and a plurality of circumferentially spaced radial receiving bores extending substantially radially inwardly within annular wall;
- a plurality of brush assemblies slidably and removably received within a plurality of said receiving bores, each of said brush assemblies including a sleeve and a plurality of metal wire bristles fixed within said sleeve;
- a securing device operably connected to each of said brush assemblies for releasably securing said brush assemblies within said housing;
- and
- a plurality of cutting passageways, each of said passageways positioned intermediate a pair of said brush assemblies for facilitating the removal fo cut material away from said center axis of said housing.
In a machine tool including a spindle rotatably supporting a shell mill arbor, said arbor including a cylindrical body portion supporting a pair of diametrically opposed keys and a cylindrical pilot positioned intermediate said keys, said pilot having a concentrically disposed threaded aperture, a cutter comprising:
- a housing including an annular wall having a cylindrical outer surface and defining a longitudinal center axis, a front face connected to said outer surface, a rear face connected to said outer surface and positioned in spaced relation to said front face by said annular wall, a cylindrical inner surface defining an arbor bore extending substantially axially inwardly from said rear face towards said front face and coaxially aligned along said center axis, said arbor bore slidably receiving said pilot, a cylindrical intermediate surface defining a counterbore extending from said front face towards said rear face and coaxially aligned along said center axis, said colmterbore in communication with said arbor bore, a lock shoulder defined between said arbor bore and said counterbore, a plurality of circumferentially spaced axial receiving bores extending substantially axially inwardly from said front face towards said rear face, and a plurality of circumferentially spaced radial receiving bores extending substantially radially inwardly within said annular wall;
- an arbor lock screw threadably received within said threaded aperture of said pilot, said lock screw including a head received within said counterbore and engaging said lock shoulder for securing said housing to said arbor shell;
- a plurality of cutters slidably and removably received within a plurality of said receiving bores;
- and
- a plurality of cutting passageways, each of said passageways positioned intermediate a pair of said brush assemblies for facilitating the removal of cut material away from said center axis of said housing.
