| Claims priority, application in Germany, 27 Feb., 1962.
Abstract:
The minimum design requirement that should be placed on any universal milling machine or the like is that it should be able to carry out all jobs in the horizontal and vertical planes. In order to satisfy this basic requirement, machines in the prior art are equipped either with a tool spindle capable of being swiveled between the horizontal and vertical planes, or with two separate tool spindles, namely a fixed horizontal spindle and a fixed vertical spindle. Now if the cost outlay necessary for constructing machines with the three separate and different types of spindles, namely the fixed horizontal, fixed vertical and swiveled spindle, is measured and compared with the precision of the work produced by operators with each type machine and with the work which can be produced with each machine, in a given time, the fixed horizontal plane machine is found to be the best value machine, that is, the lowest in cost for the quality and quantity standard of work which can be produced with such machines.
Claim:
A universal machine tool of the type having a clamping table and a tool means which are movable relative to each other in three coordinate directions, the improvement comprising, in combination, a fixed horizontal tool axis means connected to said tool means, a clamping surface adapted to receive a workpiece carried by said clamping table, said clamping surface disposed for swiveling around a first pivot axis means on said clamping table disposed at substantially 45° to clamping surface, and said clamping surface disposed for rotation around a second pivot axis means vertically disposed on said clamping table and at substantially 45° said first pivot axis means for selectively positioning all sides of a workpiece clamped on said clamping surface adjacent said fixed horizontal tool axis means for work thereon, thereby providing a more stable fixed horizontal tool axis means. |
