Automatic turning lathe GEMINI G4-CV-74

The automatic turning lathe GEMINI G4-CV-74 can produce turned parts from coils. The rotating headstock is a mechanical assembly of great precision and is used to do the turning and parting off “pipe free”. The two solide carbide constant profile tools are re-ground easily and all radial and axial adjustments are made with micrometric screws. To facilitate access to the cutting tools, guide bush and collet, the counter collet assembly can be lifted on one slide. It allows the use of a centring microscope to adjust very accurately the tool positioning. The turret is equipped with three stations, including: 1 counter pliers spindle and 2 drilling spindles. The station change is carried out in a quarter of a second by a Maltese cross mechanism. The locking is done by a conical finger whose axis is parallel to that of the spindles but located on a larger radius. This technique guarantees precise positioning. Le redresseur indépendant est équipé de 4 canons rotatifs réglables et d’un canon central mobile qui, poussé au-delà de l’axe du rotor, provoque le redressage par cambrage du fil. The CV-system is a camshaft speed variator and allows for fine turning of the feed rates. The programming is extremely easy and adjustments can be made while the machine is running. Productivity can be improved and very little maintenance is needed, as there is no gearbox. The gear changes are also eliminated. SAFETY DEVICES They stop the machine in case of : – Premature jamming. – Non-recoil of the counter-collet.. – Voltage drop in the power supply.. – Lack of lubricating oil in the tool head and turret. – End of material. – Decrease in tool head revolutions.
