Abstract
A milling machine can include a frame; a milling assembly coupled to the frame and including a drum housing and a cutting rotor located within the drum housing, the cutting rotor including a plurality of cutting bits configured to cut into a surface to define a cut surface; and a secondary edge cutter separate from the plurality of cutting bits and located to cut an edge of the cut surface such that the edge of the cut surface cut by the secondary edge cutter defines a sharper edge than the edge of the cut surface cut by the plurality of cutting bits.
Claims12
A milling machine comprising:
- a frame;
- a milling assembly coupled to the frame and including a drum housing and a cutting rotor located within the drum housing, the cutting rotor including a plurality of cutting bits configured to cut into a surface to define a cut surface having a first cut edge;
- and
- a secondary edge cutter including a planar circular saw blade separate from the plurality of cutting bits and located behind the cutting rotor to cut the first cut edge to form a second cut edge of the cut surface, wherein the planar circular saw is configured to provide a finer cut than the plurality of cutting bits such that the second cut edge of the cut surface cut by the secondary edge cutter defines a sharper edge profile than the first cut edge of the cut surface cut by the plurality of cutting bits.
A milling assembly comprising:
- a drum housing including a discharge port;
- a cutting rotor located within the drum housing, the cutting rotor including a plurality of cutting bits configured to cut into a surface to define a cut surface having a first cut edge;
- and
- a secondary edge cutter including a planar circular saw blade separate from the plurality of cutting bits and located behind the cutting rotor to cut the first cut edge to form a second cut edge of the cut surface, wherein the planar circular saw is configured to provide a finer cut than the plurality of cutting bits such that the second cut edge of the cut surface cut by the secondary edge cutter defines a sharper edge profile with less surface material breakaway than the first cut edge of the cut surface cut by the plurality of cutting bits.
A method of milling a surface, the method comprising:
- rotating a cutting rotor such that a plurality of cutting bits cut into the surface to define a cut surface having a first cut edge;
- and
- rotating a secondary edge cutter including a planar circular saw blade separate from the plurality of cutting bits and located behind the cutting rotor to cut the first cut edge to form a second cut edge of the cut surface, wherein the planar circular saw is configured to provide a finer cut than the plurality of cutting bits such that the second cut edge of the cut surface cut by the secondary edge cutter defines a sharper edge profile with less surface material breakaway than the first cut edge of the cut surface cut by the plurality of cutting bits.
