The Swiss LNS Group, world market leader in machine tool peripherals, unveils a revolutionary fine filtration solution – the SFcompact. “The SFcompact combines more than 30 years of knowledge in designing, manufacturing and servicing chip and coolant management products for the machine tool industry. It is the culmination of years of development and testing – a true high‐tech fine filtration solution complementing the rich product portfolio of LNS”, explains Jamie Towers, Global Product Manager CCM at the LNS Group.
Compared to the traditional drum filter conveyors, the SFcompact persuades with its compact dimensions and high filtration efficiency. Mr. Towers: “The floor space used by the SFcompact is 30% less compared to filter drum conveyors, and is easier to integrate – in most cases no special tank is required.” The filtration performance is outstanding: The SFcompact is designed to offer self‐cleaning filtration down to 50 microns. It handles most materials and chip types effortlessly. “A patented, automatic dual cleaning system ensures repeatable and reliable filtration.”
The LNS experts designed the SFcompact with one goal in their mind: increasing the overall productivity in a compact format. “With the SFcompact, our customers can improve the filtration efficiency considerably”, explains Towers. Improved filtration efficiency has positive effects for the whole production process: Less chips in the tank result in reduced machine cleanouts and reduced machine downtime. Improved coolant life and reduced machine wear help to minimize coolant and maintenance costs. And last but not least, a cleaner and more efficient coolant leads to improved part finish. Mr. Towers: “All of this adds up to an excellent return on investment for our customers.” Reliable and flexible
The LNS engineers focused on highest quality materials to make the SFcompact reliable and easy to adjust and service. The filtering module system is totally enclosed and robust. “Hard wearing materials on curves, sprockets, belt rollers and brushes guarantee long component life”, adds Jamie Towers. The modular construction of the SFcompact makes maintenance very easy. A filter module can be changed in only 30 minutes. Towers: “Serviceability is an important aspect. All the key components are easily accessible, often without removing the conveyor from the machine tool, and all components are widely available through the global LNS network.” The modular system also makes it easy to adapt the filtration flow to the specific manufacturing needs. For example, the number of filter modules used depends on configured coolant flow rate of the machine tool. “The flow rate capability is flexible, meaning we have the same great performance of a drum conveyor but in a more compact and adaptable package”, says Towers.
Renishaw’s proven HS20 laser encoder system has been upgraded and is now able to achieve a new maximum speed of 2 m/s for large machine tool applications. Previously the system, which can deliver an accuracy of ±1 µm/m for axis lengths up to 60 m, was limited to 1 m/s but through improvements to the electronic design it has been possible to double the speed performance.
The improved speed allows for the HS20 laser head to be designed into higher velocity applications which are becoming more common in today’s manufacturing industries. The aerospace industry is a key market for large machine tools which require long range but highly accurate encoder systems. With throughput being a key consideration in any machine tool purchase, the improved speed of the HS20 ensures that it will continue to be the preferred long range laser encoder of choice.
The HS20 long range laser system combines the ultimate accuracy of a laser interferometer with the robustness needed for machine tool applications. It offers real-time position feedback with sub-micron resolution through both analogue and digital quadrature.
Hitherto, Tornos Delta and Gamma machines were fed by Tornos SBF 320 feeders. Capable of covering a diameter range from 3 to 20 mm, these feeders gave customers using these machines a quality loader offering an excellent price-performance ratio.
Since the release of the new Swiss ST 26 and Swiss GT 26 machines, SBF 320 feeders could no longer cover the range of diameters required by these new products, with a bar capacity of 25.4 mm. This is what gave rise to the Robobar SBF 326e feeder, and decomag wanted to find out more.
An ultra-versatile feeder
The Robobar SBF 326e feeder is certainly one of the most versatile in terms of the range of machines covered; it can actually be fitted on Swiss GT 26, Swiss ST 26 and CT 20 machines, and can efficiently cover the full diameter range of these machines. With round or hexagonal bar loading capability, it provides great rigidity, making it simple to harness the full potential of the new Tornos machines.
Featuring an easy-to-use external control system, the feeder has a manual adjustment scope and an anti-vibration device on the rear of the spindle, capable of taking up to 26 bars 10 mm in diameter. The Robobar SBF 326e also provides good working autonomy, enabling users to complete a full 8 hours’ production. The new Robobar SBF 326 is now available in 3 versions, 3 metres, 12 feet and 4 metres.
Counterfeiting or falsifying products is a global problem that makes many manufacturers suffer. It is not only common for food and non-food, soft drinks, perfumes and pharmaceutical products to the fast moving consumer goods and the automotive industry.
Counterfeiting is not just an Asian issue, Europeans can also play this game. It is estimated that more than ten percent of all products are counterfeits, which constitutes a global loss between 200 and 300 billion euro each year.
Enough reason to take serious efforts to protect your products against counterfeiting. ATT (Advanced Track & Trace) in France works with manufacturers with the help of Dino-Lite digital microscopes and proprietary software that was adapted with the Dino-Lite Software Development Kit (SDK).
Quote-box-forensics-2ATT allows manufacturers to apply an authenticity feature – sold by ATT as Seal Vector – to their products. Nils Marsille, product manager with ATT: “This can be a code with a dot matrix, but it can also be engraved or even stuck in the cap of a product. This code tells us everything about the product and allows us to see if it’s a real product, a forgery or a so-called gray product, the origin of which is not immediately obvious. You can imagine that counterfeit drugs are dangerous and can even be lethal”.
Easy and useful
More than enough reason for the creation of the Anti-Counterfeiting Trade Agreement, known as ACTA. The manager continues: “We are using Dino-Lite to read and recognize the codes with our own software. With the Software Development Kit (SDK), supplied by Dino-Lite, we have adjusted our own software to work with Dino-Lite and all its features. On behalf of our clients we do worldwide research into product authenticity. Our people go in the field with a Dino-Lite, linked to a laptop where that runs our software. By scanning the product, we can quickly determine whether something is genuine or counterfeit. Based on our findings, the producer can then take action”.
At present, ATT is using approximately thirty Dino-lites. Marsille expects that this number will increase rapidly because of the ease of use and the modest size of the Dino-Lite.
On the occasion of the Siams, LNS will unveil the new Express 112. This bar loader intended to work with small diameters is an interesting addition to the product range of the company to complement the famous Tryton, particularly when floor space available is very limited. Meeting with Samuel Ventron, Product Department Manager.
For the machining of small diameter bars, the manufacturer classically offers Tryton and Tryton watch industry. Mr. Ventron explains: “For 40 years the Tryton and its system using tubes is a must with regard to guidance. With the new Express 112 we developed a bar loader that offers the same quality of guidance and an ergonomic and innovative side-loading”. If the first deliveries of this new device will take place in autumn, it can be seen and ordered from the Siams.
The best of both worlds
Designed on a girder and including NC subsets, the Express 112 is designed for bars from 0.8 to 12 mm. It is built on the strengths of the Sprint and Express ranges, namely: the frame consisting of a grinded girder, side loading even while working and the use of elements tested and validated on hundreds of devices. It combines those with a guiding quality at the level of the Tryton that is guaranteed by the independent opening of the bearings that, once closed, reproduce the classic tube of the latter.
Designed for efficiency and quality
The movement of the bar are aligned with the spindle through the 3S electronic syncing device which measures movements in real time and ensures maximum efficiency from 0.8 to 12 mm. The new Express 112, like the Sprint 565, is equipped with bearings with pneumatically controlled independent openings. Quality of guidance is maximised regardless of the position of the bar. The pusher mounted on a linear rail ensures minimized friction and high guidance accuracy. In addition, the synchronization mounted in the axis of the spindle allows to work without any effort and without vibration. The jaws to extract remnant of bar are auto-centring from 0.8 to 12 mm and require no adjustment.
The golden age of automatic lathes manufacturers probably lies in the middle of last century when three Swiss companies shared the market and were selling cam autos by tens of thousands. In the 1960s, small structures specialized in overhauling those machines have appeared.
50 years later, that trade is flourishing and offers interesting prospects. Some companies also develop new devices to enhance cam-autos capabilities. Meeting with Mr. Carlos Cancer, CEO of Seuret SA, overhaul specialist since 1964.
Cam operated machines in 2014? A solution for the future!
If some high precision turners have chosen to work only with NC machines and put old cam machines out of their workshops, others have an exact opposite approach and wish to add overhauled cam machines to their NC production areas. In our next issue we will see with Mr. Cancer that cam machines are highly needed in 2014. Why?
There are qualified operators
Cam machines are accurate
Overhauls bring good return
Innovation on cam autos
A machine that leaves the Seuret workshops is like new, painting is new, beds and slides are scrapped and assembled within a few microns tolerances… they are as in day one. Mr. Cancer tells us: “Machines are upgraded to match the precision and quality standards demanded by today’s most demanding markets, for example watchmaking. Our customers tell us that we offer the best overhauled machines on the market”. To enhance performances, the specialists of Seuret SA are also developing new solutions, for instance, the company recently redesigned the famous polygon-milling device Piranha.
Bar feeder manufacturer LNS has just unveiled a device specifically designed for the watch market. The aim? To provide a reliable device of the same quality as the famous Tryton, well-known by specialists working with small diameters, but whose capacity has been limited to 7 mm. The result? The Tryton Watch Industry 107. Interview at Orvin with Gilbert Lile, CEO Europe, and Samuel Ventron, Product Department Manager.
The driving force behind this new product is a large group of watchmakers, keen to order more than 100 devices with a maximum capacity of 7 mm. Mr Ventron explains: “To meet this customer’s requirements, capacities of 8 to 12 mm were clearly not required.” Mr Lile adds: “Thanks to the technical modifications made and to the limitation of functionalities, the Tryton Watch Industry is offered at a price which is more than 12% lower.” For this customer, that works out as almost 15 machines equipped for the same investment as the standard Tryton.
Over the years, the LNS Tryton bar feeder has become a benchmark for working with small diameter bars and functionalities have been regularly added. Its level of performance and quality is widely recognised and the company set itself the goal of retaining all its benefits whilst reducing the resources needed for its acquisition. Mr Lile explains: “The difference was made by reducing the number of options and functionalities, however, the performances required by our customers have been retained.” Mr Ventron adds: “How the product is used is identical to the traditional Tryton; the control is the same.” This means no training is needed.
