The LNS Group, world market leader in machine tool peripherals, introduces an array of innovative products at the EMO trade show in Milan. One of the new products designed by the Swiss company’s R&D team is the high-end bar feeder Express 220 S2.
“This versatile bar feeder replaces the successful Express 220 model. Following a market analysis and customer demands, we improved stability, ergonomics and autonomy”, explains Samuel Ventron, Product Department Manager Europe. Compared to its predecessor, the Express 220 S2 weighs 40% more. “We used a steel beam, CNC components and installed big, very stable stands”, says Ventron. The obtained effect was improved rigidity and stability. Ventron: “Less vibrations lead to a better surface finish of products for our clients.” The Express 220 S2 can process bars with a diameter between 2mm and 26mm. The loading capacity is up to 90 bars. The innovative bar feeder is designed for long bars used with hybrid Swiss type lathes working with and without guide bush.
Parts library for 500 parts The significant LNS experience with bar feeder families such as Sprint and Express led to the implementation of a number of optimizations: “We used the concept of the mechanical beam to improve stability for the guiding”, explains Ventron. An automatic front rest with V-shaped guiding elements ensures an optimal guiding and dampening for round and profiled bar stocks. A simple and effective loading ramp guarantees a fast loading mechanism for bars of all diameters. The new LNS design also made sure that changeover times are minimized: In only 8 minutes, all guiding elements can be changed. The new remote control with touch screen capability and the parts library, which can automatically select parameters of up to 500 programmed parts, facilitate the setup and reduce downtimes considerably.
In the spotlight: Sprint 565 S2 The Sprint 565, an automatic bar feeder for fixed headstock lathes, is designed for bars ranging in diameter from 5mm to 65mm. In the brand-new S2 version, the bar feeder was upgraded with bigger stands, a chain loader with capacity for 52mm or 65mm bars, and a high-end HMI touch screen. “The Sprint 565 S2 offers more choice for customers in the high range product sector. The extended capacity and the improved rigidity are the main plus factors”, says Ventron. The same innovations have been applied to the new Sprint 545 bar feeder for fixed and sliding headstock lathes, which is tailored to bars ranging from 5mm to 45mm with an outstanding autonomy up to 18 bars.
New air filtration system series WS 2 Another new product to be presented at the EMO trade show is the new air filtration system series WS 2. As its predecessor, the WS series, the WS 2 is highly effective with the efficient elimination of oil mist, its small and compact dimensions as well as the easy handling and integration. “We incorporated experience from the market into the development of the new product”, explains Ventron.
Swiss made “One-Stop-Shop” For more than 40 years, the Swiss LNS Group has developed innovation in lathe equipment and positions itself as the One-Stop-Shop of the machine tool industry. “We continuously invest in R&D of innovative products that maximize the productivity of our clients”, states Gilbert Lile, Chairman of the Group Management at LNS Group. With bar feeder series such as Tryton, Express, Sprint and Alpha and a wide range of chip conveyors, coolant management systems and air filtration solutions, the product portfolio of LNS is very diverse.
