600SA Machine Tools appointed agents for bar feeding manufacturer LNS Group

Switzerland-based company also recognised for its chip, coolant management and air filtration systems.

600SA Machine Tools has announced that it has been appointed as the agents to market and distribute LNS products in South Africa. For over 45 years, LNS has been based in the commune of Orvin in the heart of Switzerland’s Jura region, the hub of the bar turning industry. Since it was founded, LNS has been devoted to helping optimise the performance of machine tools, whilst increasing their productivity and safeguarding their operators.

“We only started the company two years ago, as previously reported in Metalworking News
(http://metalworkingnews.info/600sa-machine-tools-secure-with-some-recognised-machining-agencies/) and have actively been looking for complimentary machine tool and metalworking machinery and equipment manufacturing companies to represent in South Africa,” explained Richard Poalses, one of two Directors of 600SA Machine Tools.

“These include Taiwanese companies Quaser, Takumi, Takisawa, Jessey and Proking, Colchester and Harrison Alpha from the UK, Hardinge Bridgeport and Gleason from the US, and Czech Republic company Tos Trens. Through Tos Trens we also have an introduction to all the other Tos companies that make metalworking equipment.”

The LNS Group has become a world leader in the domain of peripherals for machine tools. Their worldwide presence includes nine production sites, strategically located across the globe

“The LNS Group has become a world leader in the domain of peripherals for machine tools. Their worldwide presence includes nine production sites, strategically located across the globe. I have had an association with LNS for nearly 20 years and when the previous agent was liquidated we approached LNS with the intention of representing the company in South Africa,” continued Poalses.

“LNS is one of the most recognised names in South Africa when it comes to bar feeding equipment. With more than 170 000 units installed across the world, LNS bar feeders are universally recognised for their exceptional quality and performance. Their bar feeders ensure maximum productivity on all types of fixed or sliding headstock lathes, even in the most varied of applications.”

The LNS Group acquired Fedek Machine Co., Ltd. in 2003

“From entry level solutions to sophisticated equipment, the vast range of products covers all manufacturing approaches (short-bars, long-bars or half-bars), whilst offering unbeatable reliability and flexibility thanks to systems which enable the quickest diameter changes in the world.”

“Remaining economically viable is a typical concern of all businesses. This is especially true in this pandemic period that we are currently experiencing. To do this a company needs to reduce costs, while still meeting volume and delivery targets, and one way to optimise performance is to add a bar feeder to your CNC lathe, screw machine or some other bar machine.”

“Manually feeding barstock into your machine will not give you the high-accuracy and repeatability you require. Precision workholding systems as well as precision machine tools will help machine a particularly complex, high volume part. By adding a bar feeder it will give you the ability to have unattended machine operation and to gain an edge in an increasingly competitive market.”

“The best bar feeder is the one that best meets the needs of the user for his or her particular circumstances, and those circumstances are probably as varied as the number of shops that specialise in turning.”

The LNS e-CONNECT communications system that enables the bar feeder to share data with the turning machine, can also send a variety of email alerts regarding production status and work cell health to computers, smartphones, and other devices during unattended operation

Early attempts at feeding barstock into turning machines involved simple holding or guiding devices that transmitted vibrations, required slower RPM, could damage spindles and workpieces and presented a danger to machine operators.

In the 1970s, LNS addressed all bar loading machine shortcomings by developing the first hydraulic bar feeders that reduce friction, noise and vibration. Since then, LNS bar feeders have evolved into user-friendly, ergonomic and highly efficient devices that provide a number of significant advantages.

Acquisition of Fedek bar feeders
In 2003 the LNS Group acquired Taiwan company Fedek Machine Co., Ltd, a manufacturer of magazine type bar feeders that had been established in 1986. The company was changed LNS Asia but the brand of Fedek was retained and this has become one of the most popular brands of bar feeders in South Africa.

Precise bar loading
All LNS automatic bar feeders are designed to continuously feed bar stock without interruption. Many models include a patented, direct headstock synchronisation system that ensures coordination of the bar feeder pusher and turning machine headstock. Bar feeders especially designed for very small diameter stock use a unique, scroll-type loading system.

Fast changeovers
To keep production moving, LNS automatic bar feeders include features that reduce changeover times to a matter of a few minutes. Most models are designed for lights-out operation and include automatic adjustment capabilities that require no operator intervention within the same batch.

Optimum turning machine RPM
Proper bar support reduces vibrations to enable higher spindle speeds and maintain tight tolerances. LNS achieves this with rigid, heavy-duty construction and, depending on the model, such features as automatic, self-adjusting outboard bar supports, Swiss Safety Connections and more.

Unattended operation
There’s no better way to reduce cost-per-part and meet tight deadlines than by setting up long part runs that require no operator attention. Achieving unattended and lights-out production requires bar feeders that provide automatic changeovers, hold large amounts of barstock and are proven to reliably load bars for long periods of time.

Remote monitoring
The LNS e-CONNECT communications system that enables the bar feeder to share data with the turning machine, can also send a variety of email alerts regarding production status and work cell health to computers, smartphones, and other devices during unattended operation.

Easy programming
A user-friendly, prompting, touch screen control makes setups quick and easy. The operator simply enters the barstock shape, diameter, part length and guiding channel ID. LNS bar feeders equipped with a Part Library function can store up to 500 parts programmes.

“However, LNS are not just known for their bar feeders. They are established manufacturers of chip conveyors and have developed recognised coolant management and air filtration systems, all of which we will be marketing locally.”

Chip conveyors
LNS designs and produces chip conveyors and complete chip removal systems for all types of machine. With more than 150 000 units installed, LNS conveyor systems are available in a large range of models for all types of materials and all kinds of chip. They can be fitted with coolant filtration systems effective to 50 microns.

Coolant management
LNS supplies a complete range of coolant management systems which guarantee optimal performance of your coolant system. LNS high-pressure cooling systems significantly increase machining speeds, extend the service life of the cutting tool and reduce expenditure on tooling. Currently, there are 38 000 high-pressure coolant systems delivered by LNS worldwide.

Air filtration systems
LNS designs, produces and commercialises a complete range of air filtration systems designed to counter contamination problems experienced in the workshop. Over 15 000 air filtration systems have already been installed. Thanks to their ultra-resilient construction and high level of reliability, oil mist collectors eliminate any mist, vapours and smoke, thereby helping to ensure a safe and healthy working environment and protect your production equipment.
