Lasers for the mainstream market

The latest high-power fibre-laser cutting machines from Amada, the ENSIS-AJ 6 and 9 kW, are aimed at any manufacturer needing fast piercing and cutting across a range of materials.

These high-power fibre lasers offer a host of specially developed technologies designed to overcome common laser-cutting challenges. Ease-of-use, reliability and a high level of modular automation options also feature.
Core to the advanced capability of ENSIS-AJ highpower fibre lasers is Amada’s ‘Variable Beam Control’ technology, whereby the laser beam is automatically adapted to deliver stable cutting across all material types and thicknesses. Variable Beam Control can also change instantly between a high-power density beam for piercing and a high-speed, high-quality beam for cutting, thus reducing cycle time. Regarding set-up times, only a single lens is required to process thin-to-thick materials, helping to maximise machine uptime and eliminate costly operator errors.
The company’s Auto Collimation technology is a further stand-out feature of the machines as it delivers beam diameter and focus-point control for high cutting speeds and surface quality, reducing the need for secondary finishing operations. Auto Collimation also produces a wider cut kerf on thicker materials, making for easier part removal from the sheet to reduce handling time.
“By combining our proven Variable Beam Control technology, which we have used since 2014, with our Auto Collimation technology, the high-power ENSIS models give new and existing customers a significant advantage in a competitive market,” says Matt Wood, senior product manager at Amada Europe. “In fact, 25 mm mild steel can be pierced in as little as 1 second on the 9 kW version, saving significant processing time.”

Kimla laser cutter at Barrnon

Barrnon Ltd has invested in a bespoke laser-cutting machine from MBA Engineering to work with its 6 kW fibre laser source from IPG Photonics, which features a beam splitter.

DCIM100GOPROG0107895.

The split beam means the company can now run its robotic welder and laser-cutting machine using just one source, maximising laser utilisation, as when Barrnon is not cutting, it can weld.
Barrnon director Andy Barr says: “I’d heard about the speed and efficiency of Kimla machines and went to see them for myself at MBA Engineering. After witnessing it first hand, we decided to purchase a 1530 Powercut Linear fibre laser to share the source with our robotic welder. We needed a truly bespoke machine to be fitted around the source, and MBA Engineering was able to deliver this.
“It’s fair to say we’ve been very impressed with the machine so far, and the additional support we have received since the installation provides great peace of mind,” he adds.
MBA Engineering also transported and installed the machine, liaising directly with IPG Photonics during the process, and working with the team onsite.
MBA Engineering’s managing director Bradley McBain says: “Providing a machine without a source is a very unique project, but the flexibility of the Kimla machines enables us to provide a completely bespoke service to meet a manufacturer’s requirements. As well as delivering on this project from the beginning, we will also be offering ongoing support.”

Investment at Glenmore Hane

Slough-based Glenmore Hane Group, a specialist in fine-limit sheet-metal fabrication for a wide range of industries, is using its investment in the latest automated Amada laser-cutting technologies to achieve an ever-stronger market position.

Automation is the key word here, as the company says this factor has created a significant amount of extra capacity that in turn is supporting the generation of additional revenue.
Glenmore Hane is a strong advocate of investing in the latest manufacturing technologies. A case in point is the recent arrival of an Amanda LCG-3015AJ fibre-laser. The machine is now firmly bedded in and working hard, cutting 3 x 1.5 m metal sheets with ±0.01 mm positional repeatability. Axis speeds of 170 m/min (simultaneous) mean that parts do not suffer from heat distortion.
“For us, the fibre-laser advantage is reduction in the melt effect on coated surfaces and cut edges,” says general manager Mark Hall. “The fibre laser beam kerf is very clean and approximately 10 times smaller than with CO2 lasers. In addition, real-time measuring sensors detect the slightest undulation and make material tolerance adjustments to help ensure zero rejects. Investing in this machine was one of the best decisions we’ve ever made.”
A table load weight of 920 kg and a 3 ton automatic loader/un-loader allows Glenmore Hane to run large orders on tight deadlines, around the clock. The company only operates a single-shift system, so the ability to run ‘lights-out’ is key.
“The automation allows us to take on additional work – we’ve probably got more capacity now than we’ve ever had,” explains Hall. “Ultimately, it provides us with an opportunity to grow.”
Aerospace seat fittings, computer cases, electronic plates, brackets and ducting are among the current applications for the Amada LCG-3015AJ.

Esab upgrades software suite

Columbus III version 1.6 CADCAM software for mechanised cutting has been upgraded by Esab Welding & Cutting Products.

The latest version includes the ability to calculate offers and orders for customers based on actual production data. An easy-to-use cost calculator enables fabricators to enter cost variables, such as costs for machine time per hour, cutting process (including associated consumables), preparation, programming and materials. After nesting parts using built-in design tools or importing a parts nest, Columbus III can calculate costs based on length, duration or weight of material cut. In addition, data can be exported to Excel and used for future cost calculations.
Additional newly developed functions include: keyboard shortcuts to move and rotate a parts nest in user-defined increments; rotating the parts nest and/or plate orientation to consider grain direction; a new colour to clearly delineate ‘Cut Rapid’ mode (fastest cut without regard for edge quality); and a ‘Direct Mode’ function that allows dragging lines over parts to provide quick and easy sequencing.
“Continuous improvement of the software reflects the input we obtain from our two-day Columbus III user group meeting, held annually at our Karben, Germany location,” says Holger Hahn, global product marketing manager, application software, Esab. “With our software developers connecting directly with users, we are able to make many enhancements each year, which helps maintain Columbus III as one of the most successful software suites for mechanised cutting.”

Software prevents part tilt

The newly developed TiltPrevention function in Bystronic’s BySoft 7 software means users can now create cutting sequences that reduce the likelihood of parts tilting and causing a collision with the nozzle as it travels over the sheet.

If an impact does occur, the job has to be stopped while the situation is rectified, causing loss of production, potential scrap components and, in the worst case, damage to the cutting head.
From a traditional perspective, inclusion in the cutting program of micro joints or tabs to keep components in place has been a way of preventing parts from lifting, but this results in subsequent time-consuming shaking of the components from the skeleton after the nest has been cut. There is also the added complication that broken tabs leave burrs that may have to be removed.
The alternative approach from Bystronic is to use software that can guide the path of the laser head during the cutting process so that, as far as possible, it avoids risky sections in a cycle where parts could tilt. This function largely eliminates the need for micro joints.
A special algorithm calculates the likely mechanical behaviour of each part before it is cut from a sheet, taking into account a range of parameters, including the density of the material, the geometry and weight of the component, the pressure of the assist gas flow, and the positioning of the nested parts on the sheet. TiltPrevention then recommends the start and end points of the laser nozzle so that any tilting of the parts after cutting is prevented as far as possible. In addition, the function proposes the best possible route for the head over the metal sheet, creating an optimised cutting sequence for all components on the plan.
