LVD will display a PPEB servo-controlled press brake featuring the Easy-Form Laser adaptive bending system and high-speed turbo package at MACH2006, Hall 4, stand 4665

The PPEB-EFL Turbo 80/25 - 80 Tonne by 2.5 metre model will be exhibited. In process Advanced Angle Measurement with Easy-Form Laser The PPEB press brake displayed at MACH2006 will feature LVD’s Easy-Form Laser adaptive bending technology. Easy-Form Laser is a unique angle measurement device that uses a laser to monitor and correct the angle in real time during the bending process, producing accurate bending results from the first piece.

Easy-Form Laser uses symmetrical measurement at the front and back of the die to determine the exact value of the angle of the workpiece.

The system projects straight lines composed of multiple light points onto the workpiece and the vertical part of the die, providing a measurement calculation every 20 milliseconds.

The sensing device transmits information in real time to the CNC control unit, which processes it and subsequently recalculates the correct depth adjustment to obtain the correct angle.

The bending process is not interrupted, and no production time is lost.

Unlike mechanical angle control systems, Easy-Form Laser does not extend the cycle duration and provides accurate results consistently.

It does not require calibration after each set-up.

High-speed Turbo The press brake displayed at MACH2006 will be equipped with a high-speed turbo hydraulic system, which is now available on PPEB press brakes up to 350 tons.

The turbo system increases the approach, pressing and return speeds of the press brake ram by as much as 30 percent compared to standard machines of the same size and type.

Increasing the operating speed of larger capacity press brakes improves flexibility and provides the ability to produce parts that would typically be assigned to smaller machines with higher performance.

Faster pressing speeds improve the output of higher tonnage press brakes particularly when using wide dies that require deeper penetration of the punch and longer ram travel.

LVD’s PPEB series of precision press brakes are equipped with state-of-the-art hydraulics and electronics and are offered in multi-axis configurations.

PPEB press brakes are built on a rigid frame design to ensure accuracy.

PPEB press brakes are available in working lengths from 1.5 to 15 m with tonnages up to 3000 tons.

Powerful CADMAN CNC Control and Software All PPEB press brakes feature the exclusive CADMAN control.

CADMAN is a powerful PC-based control complete with Windows operating system and the CADMAN-B 3D programming software.

The high quality design of the press brake coupled with the CADMAN control help ensure the consistency of the bend over the entire part length.

The CADMAN control, equipped with an Intel Pentium microprocessor and a 2-gigabyte hard drive, creates and stores interactive databases for bend allowance, angle corrections and spring-back.

These user-generated databases, created by actual bending results, are searched and applied each time a part program is generated.

This automatic optimization of the part program eliminates trial bending, and reduces the time required to produce a quality part.

CADMAN-B 3D software is standard in the machine control and is available as an offline programming system.

The databases developed and maintained in the PPEB press brake can be duplicated and downloaded to the offline system.

Having actual bending technologies available prior to part creation eliminates unwanted errors in the actual blank generation prior to bending, and assures accurate part tolerances throughout the process.

Press brakes noted for their speed of set-up and operating speed can be equipped with a laser that monitors the bend process in real time and makes corrections as the parts are formed

Two leading laser subcontractors have increased their productivity, reduced inspection requirements and improved material utilisation on formed parts by using LVD Easy-Form Laser press brakes (brake presses). One of the greatest advantages of laser profiling is its flexibility - it isn’t affected by material variation or grain orientation - so parts can be placed anywhere on the sheet and it doesn’t matter whether a batch of the components all comes from the same batch of material.

When it comes to forming, however, it is a very different story as these variations have a significant effect on the bend angle.

The traditional way to overcome this is to check every part, make sure that material is consistent, make sure that the parts are oriented in the same way on the sheet - and live with the fact that you might have to scrap the ‘first-off’ component.

The Easy-Form Laser system is designed to overcome these problems by monitoring the bend process in real time - using a non-contact laser method - and make corrections as the parts are being formed to ensure that every one is correct.

Leicester, UK-based SMF runs a 6kW laser producing components that are primarily destined for retail point-of-sale displays.

Batches may run into the thousands, but are more commonly between 30- and 100-off and turnaround times are generally no more than a couple of days.

SMF has two LVD PPEB Turbo press brakes, one with a 2.5m bed and one with a 3m bed, and both fitted with the Easy-Form Laser system.

SMF’s managing director Steve Morrison said he chose the LVD press brakes for their speed of setup, operating speed and the capabilities of the Easy-Form Laser system.

‘Small batch quantities can be made from all different off-cuts, and we aren’t throwing valuable material in the bin.

The grain orientation could be anywhere but it isn’t an issue.

The thickness variation we get is ridiculous - material that is supposed to be 1.5mm could be 1.44mm, 1.46mm or even occasionally 1.51mm, and we don’t know the tensile strength - the variables are unknown.

The Easy-Form allows you to fold to an accurate part very quickly - it’s a major assist in one-off set-ups.

If we can use up all the off-cuts it’s good for the customer because we don’t have to add a percentage to the price for wastage - and because it is right first time we don’t have to allow for scrap on set-up.’ Another big advantage of the system is the ability to use a three-point scan to ensure that the bend angle is correct along the full length of a long component.

This relies on the capabilities of LVD’s Turbo system to hold the ram at a fixed point while the bend angle is checked at the left-hand side, right-hand side and the centre of the component.

The machine then automatically adjusts the crowning of the bed and the relative position of the two hydraulic rams to ensure that the bend angle is consistent and correct along the length of the part.

Overall, said Morrison, the combination of quick set-up, bending speed and the Easy-Form Laser means that throughput is a lot quicker and the investment proves its worth.

‘There are a lot of people out there who won’t pay GBP 100,000 for a machine, but have three similar press brakes with three chaps operating them that are going to cost more than the depreciation on the machine.

If you’ve only got three or four parts and it takes you two hours and it takes me 30 minutes I can charge GBP 40/h instead of GBP 20 and still be half the price.’ Where SMF has taken advantage of the Easy-Form Laser’s capabilities on small batches, 5750 Components is seeing the benefits on medium-to-large runs.

5750 has always tried to offer the customer something a bit above and beyond the norm, running the highest power lasers available to allow it to cut thicker material in large sizes, and investing in large and powerful bending capability to complement it.

It bought its first LVD 4m press brake about seven years ago, and has just installed a 2200kN (220 tonf) Easy-Form laser machine with a 4.2m bed that can bend 6mm parts up to that length and up to 15mm on shorter components.

‘We do a lot of sheet metal, but the real market for lasers is plate, which is why we bought a large tonnage press brake,’ said 5750’s Andy Murphy.

‘The bulk of what we process is 4mm to 13mm thick, and most of that will be bent up.

Our philosophy has always been to buy the best equipment and stay at the leading edge.’ Murphy added: ‘We have always gone for the most productive machines and that is what led us to buy the Easy-Form Laser press brake.

Even on the simplest components the Easy-Form Laser eliminates the need for constant checking.

It means we get quality assured parts every time and boosts our productivity.’ He said that particularly on higher volume jobs there is a problem of material variation, and even the same batch will contain material with different strengths and thicknesses.

But, he said, the Easy-Form Laser eliminates the need to worry about it.

Murphy said it also increases 5750’s ability to dynamically nest parts on the plate in the most efficient way because the rolling direction doesn’t matter.

‘We get better sheet utilisation, so we can make parts more quickly and improve our productivity.

On top of everything else, I like the fact that it uses a laser.

The success of the company was built on lasers, and LVD’s laser is making our other lasers more productive.’

A press brake concept is built around a servo-electric drive based on a patented pulley principle that results in a very even distribution of forces, so a crowning table is not needed for most jobs

For the past 20 years, ACS has been supplying air filtration systems, helping manufacturers and their staff benefit from cleaner, safer and better working conditions. Specialising in the control of coolant/oil mist/smoke from machining applications such as turning, milling and grinding, ACS customises all of its products and services to deliver practical solutions.

With business growing by 17% in the past 12 months alone, the demand is increasing for ACS products is from its OEM sales to machine tool companies, as well as its retrofit business direct to end users both in the UK and Europe.

Helping boost growth further is a subcontract ’sister’ business located on the same site.

Launched two years ago, ACS Sheet Metal has won contracts from customers such as the construction division of Corus.

‘What with the success of our core air cleaning business, as well as ACS Sheet Metal, it was clear we had some thinking to do regarding the expansion of our manufacturing capacity, particularly forming, which was becoming a real bottleneck.’ said the company’s managing director, Mark Lemkey.

Although perfectly happy with its existing press brake, ACS decided to fully assess the market for a new machine.

‘It is easy to give repeat business but this can often mean you miss exciting developments,’ said Lemkey.

‘I am glad we heard about the Safan E-Brake as it has given us many advantages we would now be without had we stayed with our previous press brake supplier.’ The Safan E-Brake press brake (brake press) concept is built around a servo-electric drive based on a patented pulley principle that results in a very even distribution of forces, such that in 98% of cases no crowning table is required.

Similarly, an entirely new generation of electronics and software makes E-Brake operation extremely fast, easy and precise.

In combination with low noise levels, 50% reduced energy consumption, extremely low maintenance costs and an integrated safety system, it is easy to see why the E-Brake is attracting the attention of OEMs and subcontract fabricators alike.

ACS is also close to installing a CNC laser cutter to complement is existing punch press capability.

This will allow the company to venture beyond its current 3mm maximum sheet thickness for subcontract work.

With this in mind, it was also imperative the new press brake could cope with thicker material.

Lemkey said: ‘Not only do we enjoy the benefits of all-electric technology such as faster bending speeds, lower maintenance and less energy consumption, we can also move seamlessly into thicker gauge processing as and when required’.

Speed is critical at ACS, on both sides of the business, said Safan to manufacturingtalk.com.

Although the specification for each air cleaning system is bespoke according to the application, lead-time for new equipment is quoted at just two weeks.

Similarly, it is the speed of turnaround at ACS Sheet Metal that has helped the company enjoy considerable success in its first two years of trading.

‘For batches of 50-off and over, I can’t think of any competitors in the area that can beat us on turnaround,’ said Lemkey.

‘And now that we have the Safan E-Brake, we will move even further in front as we can run two processes simultaneously.

The days of bottlenecks in the forming section and the resulting overtime required to dissipate the problem, are long gone’.

The 4m bed on the E-Brake has already proved itself very useful since the machine was installed in October 2007.

‘Originally we were looking for a 3m machine, but it so happened that Safan had a 4m model available,’ he explained.

‘At first I didn’t think we would need the extra bed length but as things turned out, the first job that arrived after installation was 4m long material’.

Before buying the machine, ACS employed a new press brake operator and sent him and his supervisor to see the prospective Safan machine.

Suitably impressed, the machine was ordered as a package that included tooling and software, and now forms the centrepiece of the company’s manufacturing facility.

‘As the business grows we are getting more and more customers coming to see us,’ said Lemkey.

‘The Safan E-Brake is an impressive sight and confirms to our clients that we are investing in both our future and theirs’.

As well as being used in subcontract work, the E-Brake has also been set to work producing a number of parts for the company’s air cleaning systems.

The ACS range of air cleaners are designed for direct attachment to most machine tools - removing respirable particulate from the machining enclosure thereby protecting people, computers, machinery, air conditioning and heating plant.

All mist is filtered, with the moisture draining back to the coolant system or into disposal trays while the clean air is vented to the workshop.

‘Although uptake is strong, the potential market for this type of equipment remains vast,’ said Lemkey.

‘Some manufacturers struggle justifying the investment because it doesn’t add value to the end product.

However, what is the cost of a lawsuit from a retired worker who develops a cough only to discover he has lung complications from years spent working in a mist-laden machine shop?’ asked Lemkey.

It’s a salutary point and one that will surely prompt many manufacturers to ponder the benefits of working environment filtration.

* About Safan - for years, Safan has been leading the way in developing innovative solutions for the sheet metal working industry.

Halifax-based James Heal has been making testing equipment for the textile industry since the 1940s. And although the UK textile industry has declined, James Heal is still a leader in its field and sells it’s products throughout the world. Innovation and customer service have been key factors in that success, and by investing in an LVD CNC press brake, with LVD’s Patented Easy Form LaserO adaptive bending and CADMANO B 3D software James Heal is improving quality and cutting the time it takes to bring new products to market.

James Heal’s equipment is designed to mistreat textiles in almost any way you could imagine, says Production Manager, Neil Pryke.

‘We wash, we shrink, we burn, we tear, we scorch, we rip - but always under standard conditions.’ Many of these machines are only made in small numbers - maybe fifty a year - and they are made in batches to ensure off-the-shelf availability.

Batch size depends on the product, says Neil, and is calculated on the basis of an economic order quantity.

‘On something that is cheap to make, like a sample cutter, we might make a hundred-off, and on a more expensive machine we may only make ten,’ he says.

With low batch, high quality work like this, set up time becomes significant.

‘We might only make a part four times a year, and it could be made by any one of three operators - so an operator may only make a part once a year.

They couldn’t possibly be expected to remember how each part is made, but the CADMANO software gives them 3D rendered views of the tool set up and bend sequence.

We use quick-release tooling and they can set the machine up from scratch in minutes,’ says Pryke.

‘We may be making as few as ten parts, so it’s important that the first off part is right - and that’s where LVD’s Easy Form LaserO comes into its own.’ When you are trying to bend steel there are a number of factors working against you getting every part right.

One problem is thickness variation.

Standards allow for the sheet thickness to vary by plus or minus ten percent.

This can result in a difference in bend angle of plus or minus 2.6 degrees on the material that James Heal is using.

The second problem is that when you nest parts on the sheet for punching, they are aligned at different angles with respect to the rolling direction.

The tonnage you need to produce the correct bend angle can vary depending on whether you are bending along the rolling direction or across it, and that is on top of the effect of the varying thicknesses.

The bending process is also affected by the mechanical properties of the material.

Metals with a higher strain-hardening coefficient will tend to produce a bend with a larger radius, which reduces the amount the tool needs to penetrate the die - and the elastic properties of the material will cause it to spring back after bending.

The Easy Form LaserO measures the angle between the tool and the sheet throughout the bending process and compensates for spring-back to ensure that the correct bend angle is achieved first time, every time.

‘ We are trying to take the guess work out of the material - about the thickness, about the grain structure, about the strain hardening, about the spring back.

All these variables are taken out of the process by the Easy Form Laser, and that’s what sold us on the LVD system,’ says Pryke.

When it comes to producing new parts the CADMANO software is the key to getting them right first time.

James Heal generally introduces at least two new product developments every year.

Each will include around a hundred sheet metal parts that are designed in 3D using Auto Desk Inventor CAD software.

The LVD CADMANO software takes these electronic part files and unfolds them to a flat developed part using LVD’s ‘true’ bend allowances database to calculate the correct bend allowance for the tooling and material.

CADMANO then works out if the part can be made, automatically calculates the manufacturing sequence and generates the machine programme and tooling set up data - including 3D bending sequence pictures to assist the operator.

‘When we make new parts we are not reading drawings, we are going from a 3D design to a punched and formed component.

In the past it could have taken days, now we can do it within minutes,’ says Pryke.

‘The LVD Easy Form LaserO Adaptive Bending System makes sure that our production parts are right first time and the CADMANO software means we can go from the design to the part without problems or trial and error.

So we haven’t just reduced lead times, we have also made a massive saving on scrap.’

Robustly built, NC and CNC press brakes are economically priced, yet incorporate good quality component parts and include special configurations for bending up to 4.4m length.

A new range of robustly built, NC and CNC press brakes from the Turkish manufacturer, Baykal, has been introduced to the UK under a sole agency agreement with Press and Shear, Tamworth. The machines are economically priced, yet incorporate good quality component parts from well-known suppliers such as Hoerbiger hydraulics, Heidenhain scales and encoders and Delem controls. There are 16 models in the standard range with capacities from 4000kN down to 350kN and bending lengths up to 4.4 metres.

For special applications, tandem configurations can be supplied for bending parts to over 12 metres in length.

Full electronic synchronisation assures accurate and repeatable bending along the length of the down-stroking beam, with the CNC system constantly monitori ng and correcting for parallelism.

Optional power or manual crowning corrects for deflection of the press beam and the table, guaranteeing a constant bending angle over the component length.

High precision linear scales provide stroke depth measurement.
The backgauge is under computer control and actuated using a DC drive and ballscrews.
Backgauge options are X-axis with 650mm range and 330mm/s travel speed; X- / R-axis with 650 / 160mm ranges and 350 / 240mm/s speeds; and for special applications, additional axes including X1-X2, R1-R2 and Z1-Z2.

Positioning accuracy is down to 30 microns.

There is a choice of two Delem CNC systems, one for 2D and the other for 3D programming, both supported by graphical representations of the component and simulation of the bending action.

Both beam cylinders, all backgauge axes and crowning are controlled, as well as additional axes as required.

There is the option of manual X and Y axis operation or teach-in programming.

CNC programming may be either graphical, or by entry of angles or absolute dimensions.

The bend sequence is generated automatically, taking account of the bending length, material type and thickness, tooling and bend method, press force and speed, dwell time and all other parameters.
