The GEMINI G4-CV-74 automatic lathe enables production of parts from coiled material.
The toolhead is a high precision mechanical ensemble used for turning and segmenting.

The
constant profiled chisels are quick to sharpen and a simple fixing system ensures quick, precise installation. Axial and radial adjustment of the tools is carried out by means of micrometric screws.

To facilitate access to the tools, guide bush and counter-pliers, the pliers rest plate can tilt upwards. In this position, space is made for fitting the 30-power-magnification centering microscope to enable quick and precise positioning of the cutters.

The material is gripped between
two circular groove disks whose rotation carries out the feeding. The tightening pressure can be adjusted and the groove profile corresponds to the section of the wire to be machined to avoid any damage to the surface condition.

The independent straightening device is equipped with 4 adjustable rotating bushes and a movable central bush that, when it is pushed further than the rotor axis, induces rectification by curving the wire.

The turret with 3 stations, including: 1 counter collet spindle and 2 drilling spindles. The change of station is done in a quarter of a second with a maltess cross mecanisme. The closing is done with a conical finger of which the shaft is parallel with the spindles but situated on a bigger radius. This technic guarantees a precise positioning. The turret, same as the toolhead, is lubricated by the bijur pump.

The CV-system allows variation of the camshaft speed during the work cycle: easy to use controls, shorter warming-up time, increased production, no more gearing to be changed and less mechanical wear parts.

Security devices

Stop the machine in case of:

- Prematured indexing.

- Non moving back of counter collet.

- Drop of tension in electrical imput.

- Lack of oil in lubrication of turret and toolhead.

- Revolution decrease of toolhead.
