Abstract:
This invention relates to a copying milling machine, that is, a machine for reproducing on a work piece the configuration or shape determined by a pattern or template. An object is the provision of an improved copying milling machine in which the roughing operation on the work is performed by power feed means controlled by a tracer which engages the pattern or template, and in which the power feed parts can be quickly disconnected or made inoperative to permit the final finishing operation to be performed by hand in a most convenient and easy manner. Still another object is the provision of a machine so designed as to give improved rigidity and sturdiness as compared with prior machines, and at the same time an improved layout or arrangement of work table and pattern or template table with relation to each other, to enable the work and the template to be located in position more convenient to each other and more convenient to the location of the operator. A further object is the provision of a simple, sturdy, and compact copying milling machine so designed as to accommodate an increased size of work piece as compared with many prior machines, and one in which the milling operation is performed at a convenient location with relation to the eyes of the operator, notwithstanding that different work pieces operated upon at different times may have considerably different vertical dimensions. A still further object is the provision of a copying milling machine so designed and constructed that transmission of vibrations from the work piece and the milling spindle to the tracer is reduced to a minimum.
Claim:
A copying milling machine comprising an upstanding main column, an upstanding auxiliary column spaced from the main column, a work table in the space between said two columns, said table being mounted for vertical movement and also longitudinal horizontal movement, a substantially horizontal crosshead resting on and bridging the space between said column, a vertical milling spindle head supported from said crosshead and displaceable horizontally thereon in a direction transverse with respect to the direction of longitudinal movement of said work table, and a template table spaced laterally from said work table and located at least partly on the opposite side of said auxiliary column from said work table, said template table being operatively connected to said work table to move therewith during both the vertical movements and the longitudinal horizontal movements of said work table. |
