Optimise cutting with Esab digital solutions

To help fabricators and manufacturers drive continuous improvement in traceability, documentation, asset management, productivity and quality, Esab has revealed its newly developed Digital Solutions platform.

Esab Digital Solutions, including Esab WeldCloud and Esab CutCloud, is able to connect digital ecosystems for manual/robotic/automated welding and cutting automation, respectively.
The platform was officially demonstrated for the first time at the recent EuroBLECH 2018 exhibition in Germany, where it was powered by Microsoft Azure IoT and utilised the ThingWorx Industrial Innovation Platform from PTC.
“We collaborated with Microsoft because Azure allows for a reliable and secure architecture that sends data from a digitally connected system, directly to the cloud,” says Mike Pantaleano, VP data driven advantage/digital solutions, Esab. “Eliminating the need for an on-site server or large IT infrastructure especially helps job shops and smaller operations gain the benefits of data management. Our reference architecture using ThingWorx also allows for on-site and hybrid (on-site/cloud) configurations, enabling us to configure and scale a connected solution for companies of all sizes. The right digital solution lets customers focus on improving their core business activities.”
Without formal data analysis programs, welding and cutting operations tend to over-estimate equipment utilisation rates and under-estimate actual arc-on time when quoting products.
“If you can’t measure it, you can’t improve it,” states Pantaleano. “Some welding operations think they’re at 30 to 40% OEE when they’re actually in the mid-teens. The applications and dashboards that are part of Esab Digital Solutions enable customers to assess their current situation at a glance and then start building baseline numbers. Once they determine what their ‘steady state’ is, they can identify areas for improvement.”

Gratnells showcases latest investments

At the recent Advanced Engineering show in Birmingham, Harlow-based Gratnells Engineering opted to showcase its latest laser technology developments. In 2018, the company invested in a new BLM LT Fiber machine, allowing it to expand its capabilities and ensure clients benefit from even faster turnaround times.

The new machine sits next to an existing LT5, a laser tube-cutting machine designed to cut from small to medium diameters and thicknesses of metal tubular sections. The LT Fiber allows tubes of any shape to be cut, along with the processing of special sections and even open shapes without any additional special equipment.
According to Gratnells, tube laser cutting is continuing to grow in popularity as it offers a quick route to a precise finish, eliminating conventional, time-consuming stages such as marking out, sawing and finishing, while delivering significant cost savings.
Investing in the latest laser technology has increased Gratnells Engineering’s factory efficiency by allowing unloading to various positions, with finished parts from one machine being unloaded while production continues uninterrupted on the other. The need to manually separate parts from different orders has also now been eliminated.
Gratnells’ factory can today turn around tube laser-cutting jobs within 3-5 days from receipt of order and, using sophisticated software, can process parts from a variety of media, including 3D models, XT files and SolidWorks. This capability is particularly beneficial for bespoke automotive and point-of-sale components where minimum quantities can start
at 1-off.

Drentea invests €3m in production boost

Drentea, part of the Dutch VDB Group, has invested €3m in the improvement of output and sustainability at its factory.

The combination of machines in the production line at Drentea now consists of a Salvagnini S4 and P4, on which Drentea can punch, cut, twist and bend metal. In addition, a Salvagnini L5 fiber laser is accompanied by a fully automatic sorting centre. This fibre laser generates much more energy from the same amount of power, resulting in substantially lower energy consumption. By producing products on this new line, the company has increased both its production capacity and flexibility.
“We want to achieve further growth by continuing to invest in state-of-the-art production facilities,” says CEO Bert Top. “These investments contribute to a natural evolution towards smart industry and result in a doubling of production capacity.”
In addition, enormous progress is being made in the field of sustainable production. The expectation is that, using this method of processing, the percentage of waste will be reduced by at least 90%. Drentea has now succeeded in integrating its entire business activities in a sustainable circular manner.
“This time of transition to a sustainable manufacturing environment offers Drentea plenty of opportunities to realise its green ambitions,” says Top. “Here at Drentea we focus on smart designs, the complete re-use of materials, production without waste and the use of regionally sourced green energy.
“We want to control our own raw material chains and energy supplies,” he continues. “The time in which price was decisive only tilts to a time where sustainability has actually become measurable. With this new production line we are more than ready to take advantage of the possibilities that time will provide.”

90% faster laser cutting

Amada is making its new Clean Fast Cut (CFC) technology available as standard on the company’s 6 and 9 kW fibre laser cutting machines.

CFC is said to be up to 90% faster than standard Clean Cut (CC) and can use less nitrogen when cutting 8 mm stainless steel, for example. The technology was developed at Amada’s R&D centres in Japan and has been tested at the company’s European Laser Technical Centre near Munich.
The gains stem from a new design of cutting nozzle that optimises gas flow dynamics, and the company’s own fibre laser engine with 3 kW diode modules – said to be the largest in the industry.
CFC is capable of delivering benefits to general subcontractors that cut mid-thickness stainless steel and mild steel, as the higher cutting speeds and lower gas consumption give a reduced cost-per-part. Manufacturers needing to weld or paint parts after processing will also enjoy advantages as there is no need to clean the edges, which is necessary when using oxygen to cut mild steel. Food, marine, medical and chemical plant equipment producers will benefit too, thanks to higher productivity in stainless steel processing.
On a 9 kW Amada fibre laser, CFC is effective on stainless steel from 4 to 15 mm thick and mild steel from 4 to 12 mm, while on a 6 kW machine the technology will produce gains on stainless steel from 4 to 12 mm and mild steel from 4 to 8 mm. Below 4 mm thickness, Amada says that its standard CC is very productive. Importantly, CFC is not an optional extra and is shipping now as standard with newly ordered Amada 6 and 9 kW fibre laser machines.

Fibre laser boosts revenue at start-up

New start-up Staffs Laser Ltd has selected a Trumpf TruLaser 2030 Fiber to help propel the business into the Midlands subcontract sheet profiling market.

Installed at the time of business launch in April 2018 as the company’s sole laser cutter, the TruLaser 2030 fiber is on target to help Staffs Laser achieve a turnover of £800,000 in its first year of trading, way ahead of the £560,000 originally budgeted.
Staffs Laser is the brainchild of Eddie Hopkins, who has been working in the laser cutting arena for the past 15 years.
“At my previous employment we had CO2 laser cutting machines, which are fine but cannot match the speed of fibre on thinner sheet,” he explains. “My old bosses were reluctant to invest in the latest fibre technology, so I decided to leave and start my own business.”
Working out of premises near Stone, located between Stafford and Stoke, Hopkins knew he would have to invest from the outset, and Trumpf was always going to be first choice. I knew Trumpf machines well and consider them to be the market leader. In addition, they provide really good service, which I knew would be key to a new start-up business like mine.”
With limited budget, Hopkins duly installed Trumpf’s entry-level machine, the TruLaser 2030 Fiber.
“Such has been the ramp up in demand that the TruLaser 2030 is already running 12 hours a day during the week, and 6-7 hours on Saturday – in fact, we are struggling to keep up and will soon have to consider running overnight,” he explains.
The company recently achieved a record monthly revenue of £80,000, which is nearly double the figure originally budgeted.
