The upcoming market launch from the Swiss specialist is more than just an evolution of its Sprint range, the new ULTRA 80 is much more akin to a real revolution in the field of bar feeder systems.
LNS is an innovator in the bar feeder market and it is the first company to offer an extremely rigid 700kg mineral cast iron support beam. This mass helps ‘seat’ the machine in its position. It guarantees machining quality by damping the vibration generated by the rotating bar. To make this support beam, LNS Group uses a specific patented manufacturing process. The inserts and metal plates are pre-positioned and integrated into the mass and thus are immediately positioned correctly when demoulding. This core component of the machine is geometrically finished, and the precision of manufacturing is such, that no reworking is required. The complete machine weighs up to 2 tonnes and remains perfectly stable even while long bars with a diameter of 80mm and weighing over 160kg are rotating.
In response to requests from its customers, the LNS Group designed a highly flexible front rest system to reduce the number of cases where users need to change the guiding elements. The front rest is an essential support element for the bar before it enters the lathe spindle, keeping the bar perfectly centred, while accepting a wide range of bar diameters. It adjusts automatically to bars of different diameters, so the operator does not have to change the guiding elements. This innovative and patented front rest is complementary to the hydro bar principle and does not replace it, moreover the ULTRA 80 follows the same principle to offer ideal guidance characteristics. This technology, which the company has built its reputation on, is therefore still very much a feature of the ULTRA 80. The high oil flow rate contributes to optimal hydro-dynamic centring of the bars.
The Human Machine Interface (HMI) supplied with the ULTRA 80 has a large colour touch screen and numerous context-sensitive menus, guiding the operator through the actions. Extremely graphical, this HMI offers a layout that allows users to directly access the information needed for increased productivity and safety. The new unit provides messages and alerts with text and images. The ULTRA 80 is available in two versions, with internal ramp or external lift to offer customers the configuration best suited to their requirements. The oversized insertion and extraction system are also equipped with a booster for all chuck types.
