Laser cutters help Redhill reach new heights

Redditch-based access equipment maker, Redhill Manufacturing, has purchased two fibre laser cutting machines from Nukon Lasers UK, helping to meet increased demand for the company’s products.

The first of the new fibre lasers, a Nukon ECO 315 4kW flat sheet model, was installed at Redhill’s newly acquired facility in December 2022. The second laser, a Nukon NKT-125 2kW 3D tube cutting model will arrive later in 2023 complete with a fully automatic Nukon 8 m loading and unloading system.

Following a fire at the company’s previous manufacturing site, Redhill wasn’t simply faced with finding new premises. The business also needed quality CNC machine tools to maintain its standing as the only UK manufacturer of ‘kitemarked’ British Standard mobile safety steps.

“As I didn’t really know the Nukon brand, the companytook me to a customer in Sheffield that had been using a Nukon flat sheet metal laser for around a year; all so I could see the machine in action and chat to the operators about their experience of using it,” says Redhill Manufacturing’s managing director Andy Colley.

Hearing glowing reports of how the Nukon flat sheet metal laser had streamlined the process of cutting complex precision components at the Sheffield business, Colley then travelled to Nukon’s European manufacturing facility to see a Nukon tube laser machine in action.

“The tube laser machine was just as impressive as the machine I’d seen in Sheffield,” he says. “The build quality was very good. Both machines were competitively priced, and the features include nLIGHT fibre lasers with adaptive beam optimisation and Lantek Expert nesting software.”

Like a brand new machine after 21 years

“Quality never goes out of style,” they say. Well for Water Jet Sweden cutting machines quality never goes out of performance either! The recent refurbishment of a 21-year-old waterjet cutting machine to almost-new condition by the in-house team recently demonstrated this perfectly, making it ready for many more years of quality cutting.

In 2001, Water Jet Sweden sold the machine to a Norwegian waterjet contract cutter. After 21 years of cutting, the customer decided to upgrade its workshop by investing in a new machine. Like many other well-maintained machines from Water Jet Sweden, the performance was still good, and a general ‘facelift’ could be worth the investment. The customer service team at Water Jet Sweden seized the opportunity and bought the old machine.

“We’ve supported the customer since the machine was delivered in 2001, and have good knowledge of both operating hours and service history,” says Ronny Martinsson, customer service manager at Water Jet Sweden.

Looking at the refurbished machine, it is difficult to imagine that it has been in production for 21 years. Although it looked a little more run-down than when purchased, after a thorough clean, the potential was clearly visible. Every renovation project is different: this time the frame was repainted, new table grids installed, hoses replaced and, most importantly, the electrical system replaced with a new Fanuc CNC system. The system change included everything from cables, motors and electrical cabinets to a modern PanelOne operator panel.

The refurbished machine is now ready for delivery to a new customer in Germany, a forging company that will use the machine as a workstation in its workshop. It cost about 60% of what an equivalent new machine would cost.

DNE Global range extended with LC4 model

TheEngineering Technology Group (ETG) says that the success of DNE Global fibre laser cutting technology has been phenomenal since its introduction to the UK last year. Now, ETG is extending the line-up with the arrival of the LC4. The latest high-quality cost-effective fibre laser cutting machine has a larger capacity and a host of features that reach beyond the smaller LC3 variant.

The new LC4 machine is suitable for a wide range of applications, from thin to thick sheets of steel, stainless steel, aluminium and non-ferrous metals. Delivering greater profit per part with its low investment level, comparatively low operating costs and low maintenance requirements, the LC4 is available in four variants: the LC4 2000, 3000, 4000 and 6000 with each of the four models signifying the respective laser power from 2 to 6 kW.

The LC4 can accommodate sheets up to 4 x 2 m with a cutting area of 4120 x 2110 x 100mm, and a maximum workpiece weight up to 1300kg. Depending upon the selected model and material in-cut, the LC4 can cut sheets from 5 to 20 mm thick at high speed and with a changeover time of just 27 seconds. The maximum positional speed in parallel axis X/Y is 100m/min with a maximum positional speed of 140m/min.

When it comes to precision, the new LC4 has a bilateral repeatability positioning of one axis (R) of 0.5mm,offering an average bilateral deviation of one axis (M) of 0.1mm with an edge detection precision level of ±0.5mm. Regarding footprint, the compact machine has a floor area of 13.1 x 6.4m with a height of 2.74m.

Investment proves key to growth and diversification

Milltek Sport has, for the past 40 years, being at the forefront of the design and manufacture of aftermarket performance exhaust systems, but with one eye on the future it has recently created a £3m Advanced Manufacturing Centre, adjacent to its Derby headquarters. At the heart of this investment are three machines from BLM Group that incorporate the very latest in fibre laser, robotics and bending technology.

While Milltek Sport’s core products will remain in demand for many years to come, the rise of electric vehicles influenced the company’s decision to invest, a move that is allowing it to appeal to new markets, such as heat shield manufacture for EVs. The three machines from BLM Groupinclude a BLM LC5 combination flat sheet and tube laser cutting system, and the BLM LT Free Hi-Flex five-axis, twin-robot, fibre laser cutting cell.

BLM Group’s LC5 integrates separatemodules for tube and flat sheet processing to enable a switch from tube processing to flat sheet instantly, without any need to reconfigure the machine. Milltek chose the 4kW (12kW optional) fibre laser for its machine, a choice that provides the capability to cut stainless steel up to 15mm thick. Adding to this versatility is the electric sheet pallet change system with dual shelves for sheet and tube.

Similarly, the BLM LT Free Hi-Flex five-axis robot cell features twin robot arms that can be operated individually, with a divider allowing one part to be cut by the 2kW fibre laser, while another is being set-up.Or, if the part demands it both robots can work in tandem.

Steve Pound, managing director of Milltek Sport, states: “We are seeing efficiency improve dramatically; up to 40% gains on some components.”

Bodor unveils scanning laser cutting technology

Bodor Laser showcasedits latest laser cutting solutions, including the company’s new scanning cutting feature, at the Global Industrie trade show in Lyon last month. On the stand was a P3 12kW sheet fibre laser cutting machine and a T230A 3kW fibre laser tube cutter. The company presented live demonstrations of its new scanning laser cutting, a new technical innovation applied to the P3 12kW model. Bodor machines are available in the UK from World Machinery.

Bodor scanning laser cutting technology tackles long-existing pain points in the metal fabrication and laser cutting industry, such as poor processing efficiency of non-ferrous metal, damage to the beam from the highly reflective material batch process, and limited output power of laser cutting equipment.

With an optical system device, optical path spatial programming technology and patented process algorithm, scanning cutting enables a significant increase in cutting material thickness with the same machine power band,while also delivering a substantial enhancement in cutting speed.

The secret behind Bodor scanning cutting lies in dynamic spot cutting, with the spot travelling 30 m for every 1 m of cut, which significantly increases the efficiency of the laser energy absorbed by the material being processed in contrast to static spot cutting.

Amelie Yu, regional sales manager (France) at Bodor Laser, says: “Compared with conventional laser cutting machines, the same power laser scanning cutting machine achieves a cutting thickness increase of 100% and cutting speed of 180%. Scanning cutting as a new technical feature makes Bodor’s laser cutting solutions a real game-changer in processing thick and highly reflective materials at fast speeds with minimised costs.”
