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.”

Midtherm lasers set for growth after £1.2m investment

A specialist subcontract laser cutting and forming specialist is reaping the operational and environmental benefits of a £1.2m machine investment. Midtherm Laser, which employs 45 people at its factory in Dudley, has increased its capacity and speed of processing thanks to the installation of a new Bystronic Bystar Fiber 12kW laser with part automation.

One of the largest purchases in its 23-year history introduces the next level of power in fibre laser cutting. It will help the company deliver high cutting dynamics and thin to thick cutting capabilities to a customer base that spans aerospace, automotive and decorative work, to food processing, agricultural and conveyors.

The machine has also made a massive difference to the firm’s environmental performance, with the Bystronic model replacing two older CO2 machines and delivering a 50% energy saving, the equivalent of powering 2100 average homes every month.

“Our expertise in laser cutting and metal forming is respected throughout our sector and has led to us increasing sales by a further 6% last year, a great achievement considering the volatility of the market,” explains Mark Hannon, director of Midtherm Laser.“The 12 kW Bystar Fiber is a class-leading machine that can cut from 0.5 to 30mm in mild steel, aluminium and a host of other materials. It gives us more capacity to target new opportunities and, importantly, means three quarters of our machines are now fibre technology instead of gas.”

He adds: “With this in mind, and when you consider we’ve also invested in LED lighting, sensor switches, and electric vehicles and charging for our staff on the road, it’s not difficult to see how we have managed to cut our energy usage in half since 2018.”
