Abstract:
An object of the invention is the provision of a generally improved and more satisfactory machine tool, and especially one which is in the nature of a universal tool so far as milling, drilling, and boring are concerned, capable of accurate and efficient performance of a greater variety of work operations than has been possible with prior machines. Another object of the invention is to provide a machine having a machine bed and a work table and spindle head mounted on the bed for relative movement to each other for supporting a work piece on the work table and a cutting tool on the spindle head, so that precision cutting operations may be performed on the work piece including drilling, boring, and milling operations. Still another object of the invention is to provide a machine having a machine bed, a work table, a column and a spindle head in which the column and work table are movable on the machine bed relative to each other and the spindle head is movable on the column relative to the machine bed and work table for performing precision boring, drilling, milling and other machining operations on work carried by the work table by a tool carried on the spindle head. A further object of the invention is to slidably mount a column on a machine bed for movement toward and from a work table slidably mounted on the front side wall of the machine bed with a suitable cutting tool adjustably mounted on the column so that a work piece mounted on the work table can be machined by either a boring, drilling, or milling operation in which the cutting tool can be mounted in close proximity to the column with the work positioned on the work table adjacent to or overlying the machine bed in order to eliminate bending of the machine parts for obtaining higher precision in the combined cutting operations performed by the machine. A still further object of the invention is to provide a machine on which several different types of machining the top side of a machine bed toward and from a work table mounted on another side of the machine bed for slidable movement in angular relation to the column to provide a rigid support for the work on the work table by supporting it adjacent to the machine bed while the cutting tools may be mounted on the column for relative movement to work on the work table with the column movable toward and from the work along the top of the machine bed for eliminating clearance of the work table and the column on the machine bed and bending or flexing of the work table and column during machining operations. A still further object of the invention is to provide a machine on which several different types of machining operations can be performed with high precision in which a column is slidably mounted on guideways on opposite sides of the top surface of a machine bed, a work table is slidably mounted on the front side of the machine bed and the top portion of the machine bed formed with a trough between the guides for the column so that cutting tools adjustably mounted on the column may be moved into the trough in the machine bed below the guideways and top surface of the work table at opposite sides of the machine bed in order to produce machining operations on work carried by the work table from below the bottom surface to above the top surface thereof. Another object of the invention is to provide a machine bed with horizontal guides on one side slidably supporting a work table provided with work supporting means on both the side and top surfaces thereof; a pair of spaced horizontal guideways on the top of said machine bed slidably mounting a column for movement toward and away from the work table; a spindle head movably mounted on a side face of the column facing the work table for supporting cutting tools for producing machining operations on work supported on one or both sides of the work table; and controls for operating the work table, the column and the spindle head relative to one another on the machine bed mounted on the side of the machine bed, column and spindle head adjacent to the Work table so an operator may conveniently control and operate the work table, the column and the spindle head in a convenient manner to produce boring, drilling, and milling operations on work carried by the work table While visually watching the operation. Another object of the invention is to provide a machine having a machine bed formed with horizontal guideways for slidably mounting a work table on one side thereof in which the portion of the machine bed below the guideways is recessed so the guideways and work table extend beyond one side of the bottom portion of the machine bed to an extent sufficient that a tray may be mounted below the work table and horizontal guideways on the machine bed for receiving chips and coolant resulting from machining operations. Another object of the invention resides in providing a machine having a machine bed formed with spaced guideways on the top wall; spaced guideways on one side wall extending in angular relation to the guideways on the top wall; a work table slidably mounted on the guideways on the side wall; a trough formed in the top wall of the machine bed between the guideways inclining downwardly toward the guideways on the side wall thereof and having an opening adjacent to the guideways on the sidewall extending downwardly for discharge of chips and coolant; and a tray mounted on an overhanging portion of the machine bed below the opening from the trough, the guideways on the side of the machine and the work table. Still another object of the invention resides in providing a machine bed; a column slidable on the top wall thereof; a spindle head movably mounted on one side wall of the column over a work table slidably mounted on one side of the machine bed; and a turret type head mounted on the top of the column having one or more radial arms extending beyond the sides of the column for carrying a counter support, a slotter, a vertical milling head, grinding head or the like, on the free end of the arms for movement into position adjacent to the spindle head for either attachment thereto or cooperation therewith in performing machining operations on work mounted on the work table. A still further object of the invention is to provide a machine having a work table provided with vertical and horizontal surfaces in which the top portion and the horizontal surface of the work table extend above the guides on the machine base so auxiliary work supports may be attached to either the top or side portions of the work table and a rotatable auxiliary work support may be applied either to the top or side surfaces of the work table for supporting work to be machined on any of the several sides thereof according to the adjustment of the work table. The work table is so constructed and arranged with respect to the bed and the column 89 mounted thereon that the work may be supported so it will overhang the sides of the work table on which it is supported whether in a horizontal position or a substantially vertical position in order to position the work for machining operations so bending stresses may be eliminated and greater precision of machining operations obtained.
Claim:
A boring, drilling and milling machine comprising a machine bed formed with side guideways on a substantially vertical surface and top guideways on a substantially horizontal top surface in angular relation to said side guideways, a Work table mounted on said machine bed for slidable movement on one of said guideways, a column slidably mounted on said machine bed on the other of said guideways having a guideway extending in angular relation to the guideways on said machine bed, and a spindle head slidably mounted in the guideway on said column. |
