Automatic lathe with digital command control for the turning of metal nuts and bolts turned with profitability in small and very small series.

摘要

This invention deals with a lathe with digital command control on 4 controlled axes, equipped by two turrets supported by round guides cantilevered from the principal structure, one of which carries rotating tools always fixed in the axis of the piece, for frontal and recovery tooling. The other, equipped with cross-movement control, carries the tools for lateral tooling. In addition, two vertical slits, one above the other, and under the mandrel carrying bar, which carries the cutting and rough shaping tools, are connected between themselves by a system of levers and connecting rods, and constitutes the fourth controlled axis. Such a configuration permits having up to three tools under tooling simultaneously, with only four controlled axes.
