LNS Group to showcase an array of new products at EMO

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.

More choice in the high range product sector: LNS introduces the upgraded Sprint 565 S2 and the Sprint 545 at the EMO in Milan.

“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.

One-stop-shop novelties at EMO

At the EMO trade show in Hannover (16-21 September 2013), LNS will showcase many news in its “one-stop shop” concept on its booth and on the Mazak one.
Today, the LNS Group is the global leader in automating machine tools. “We support our customers with a wide range of peripheral products to optimize their efficiency in all of their key markets. And we want to guarantee flawless service wherever our customers are”, explains Gilbert Lile, CEO of the LNS Europe Business Unit. At the same time, LNS remains dedicated to Switzerland, the place where it all started. Mr. Lile: “The LNS Group’s research and development is driven mainly from Switzerland. We recently opened up a dedicated lab in Orvin and expanded our R&D team. We want to remain one step ahead when it comes to innovation and secure our position as world market leader.”

Alpha 552 bar feeder for the first time in Europe
The entry level bar feeder’s main characteristic is its outstanding reliability. A mechanical beam gives the bars optimum stability; long guiding elements provide optimal guiding and dampening. A reinforced front leg guarantees improved rigidity. “The Alpha 552 can process bars with a diameter range from 5-52mm and a length up to 4.2 meters”, says Samuel Ventron, LNS Europe Product Department Manager (more info here).

Better working conditions…
Other products on display at the LNS booth (Hall 17/D16) are the newly designed oil mist collector Fox WT700 and the Fox SC500 spray cabin. “The Fox WT700, exclusively shown at EMO, is the first model of the WT product range that will be available at the beginning of 2014 and replace the WS series. We did not only improve the design, but also the performance, ergonomics and the lifetime of the filters”, explains Mr. Ventron. “With the development of the SC500 spray cabin, we want to contribute to providing a healthy, clean and safe work environment. The SC500 convinces with high efficiency filtration, low noise level and its mobile and compact design.” (More info about the SC500 here).

Quick Load Servo III with innovative Ethernet connection
At the Mazak booth (Hall 27/C61) visitors will see a Quick Load Servo III bar feeder together with a new Integrex multi-tasking machine. The Quick Load Servo III MI and the CNC will be interconnected with an innovative Ethernet connection to optimize communication and improve productivity.

LNS Group joins with Japanese Yoshida Tekko KK to maximize their global presence

Reinforcing the one-stop-shop strategy: Yoshida Tekko KK, a leader in the Japanese market for chip conveyors, coolant systems and high level filtration systems, joins the Swiss LNS Group. This strategic union allows the LNS Group to further expand in Asia, to serve its customers globally and to offer coolant system and conveyor innovations in the Asian markets.  

The headquarters of LNS Yoshida KK in Nomi, Japan.

The Swiss LNS Group acquires the assets of Yoshida Tekko KK. Founded in 1969 Yoshida Tekko KK is one of the leading companies in the Japanese machine tool industry with more than 100 employees. “Leveraging on both companies’ product portfolios, this strategic union allows us to share technologies and offer our customers a complete solution to automate and optimize their machine tools”, states Thomas Boehmer, CEO of the LNS Group. “We want to optimize the material flow and enhance productivity and efficiency for our customers from the start to the finish of the production cycle”, says Mr. Boehmer.

New company in Japan: LNS Yoshida
The acquisition gives the LNS Group a base to introduce new products into the Japanese market and serve the Japanese clients directly. As LNS is already the market leader for bar feeders in South East Asia and has production facilities in Taiwan and China, the union with Yoshida will further facilitate the Asia expansion and the implementation of the One-Stop-Shop strategy.

Step by step: LNS’ expansion to the One-Stop-Shop
With highly successful bar feeder series such as the “Express” and “Sprint”, LNS has been a world market leader for nearly 40 years.  “The acquisition of the chip conveyor company Turbo Systems Inc. in 2002 gave LNS a market leadership position for conveyors in the USA and a base for expansion in Europe. Since then, we developed the One-Stop-Shop strategy, to automate the CNC machine tools with a concentrated array of peripheral products”, explains Thomas Boehmer. The acquisition of the Italian air filtration specialist Fox IFS in 2010 and the introduction of the air filtration products to Asia was another step on this expansion track. Mr. Boehmer: “While the One-Stop-Shop is already implemented in the United States and Europe, the acquisition of Yoshida into the LNS Group allows us to realize this strategy in Asia, too.”

New range of bar feeders

After the success of the SBF320 bar feeders on the Delta and Gamma product ranges, Tornos has introduced a new low-cost line of “e” bar feeders at EMO.

These bar feeders are different from their predecessors in that they are more simple in design and offer basic functions. They have an offset control on the bar feeder and guide components for a single channel.

Optimal integration
These bar feeders were developed in conjunction with the development of the machines and this helped eliminate all the trade-off and interfacing-related problems such as those sometimes encountered with so-called “universal” bar feeders.

Not revolution, evolution!
By adopting the characteristics that made its predecessors so successful, Tornos can now offer a “simple” alternative to its high-end bar feeders.
On the “e” range, all the controls are found in one unit. The number of guide components offered as an option has been increased and the guide channels are inter-compatible between models. Its operating flexibility is a real advantage.

Close attention has been paid to the design of the SBF212e which will support turning machines up to a spindle diameter of 12 mm. Screw loading prevents small diameter bars from overlapping. The insertion into the guide at the screw outlet will be accompanied by a mechanical movement.


  • Optimum integration
  • Guaranteed bar guiding
  • Offset control on the bar feeder
  • A single guide channel per guide
  • One supplier for machine and bar feeder
  • Excellent price/performance/quality ratio

These new peripherals were premiered at EMO and the first orders will be delivered at the start of 2012.
