Description: |
| Abstract:
My invention relates to that class of milling machines especially designed for milling or dressing the nut faces of brass valve bodies and fittings of the like character, and it has for its object the production of a machine which can simultaneously mill or dress two pairs of faces, one pair of which is at one end of the fitting and the other pair at the other end thereof, and which is simple and efficient in its action and automatic in its operation in causing the work carrying table to travel back and forth between the cutters and to turn the work to present new faces to be cut.
Claim:
In a milling machine of the character described, the combination of a supporting and guiding bed, a transversely movable work carrying table carried thereby, means for securing work to said table, opposing 4.5 cutters for operating on the lower part of the work carried on said table, and opposing cutters for operating on the upper part of said work, said opposing pairs of cutters having their axes occupying a plane oblique to the table so as to act on the work successively at its lower and upper parts. |
