Automatic turning lathe GEMINI G2-CV-74

The automatic turning lathe GEMINI G2-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. The counter collet attachment holds the part during part off, giving a “pipe free” component. 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 material feed is controlled by two feed rollers. The feed rollers pressure can be adjusted to eliminate all possible marks on the outside of the material. The straightening device is fitted by five rotating straightening holders and carbide pads. 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: – Voltage drop in the power supply. – Lack of lubricating oil in the tool head and turret. – End of material. – Decrease in the revolutions of the tool-holder head.
