Product innovations for the future

Combined friction stir welding and machining processes, scalable manufacturing for micro-technology and high-productivity twin-spindle machining – are just three of the new product innovations by the Chiron Group that are now available in the UK from the Engineering Technology Group (ETG).

High dynamics and stability, plus a large working chamber with a twin-spindle concept and a spindle distance up to 1200 mm – this is the 22, 25 and 28 series from Chiron. Offered by ETG, Chiron says that the new machines are primed to set a new benchmark in terms of productivity and precision in this size range – and they are demonstrably doing so already. As an example, a DZ 25P that has been in use for two years in manufacturing structural components for the automotive industry. All in all, this turnkey solution has provided “a stable and high-precision process with greatly increased output in comparison to the previous system”, according to the customer.

In addition to double-spindle applications such as battery and e-motor housing manufacture, these new series are fully capable of massive machining applications starting with solid blocks. The extremely stable portal design forms the basis for high precision while the well-thought-out working area and user ergonomics enable flexible integration of a wide range of automation solutions for production process reliability.

In another development, the Chiron Group and ETG are now offering a manufacturing system for the micro-technology sector that provides high-precision automated machining of workpieces with maximum dimensions of 50 x 50 x 50 mm.

Finally, by combining FSW and machining, Chiron is developing a forward-thinking innovation. The first projects are already underway at a technology partner company, resulting in the first turnkey machining centres such as the MILL 2000.

Festool automates tool-making department

In mould and die making, individual machining processes are increasingly being combined into automated production cells with integrated handling. The main advantage is a higher degree of machine utilisation, as the systems can operate unattended 24/7. Two prerequisites for the realisation of such autonomous systems are more intensive digitalisation of the processes consistent with Industry 4.0 and an increased level of investment.

One company that has followed this automation route is German power tool manufacturer Festool, which produces complex die-casting mould tools and plastic injection moulds for producing its products at a factory in Neidlingen. The toolmaking department has installed a robotic production cell based on machining centres manufactured by German firm, Roeders. Similar technology is available in the UK and Ireland through Roeders sole agent, Hurco Europe.

To implement the installation, Roeders supplied two of its RXP five-axis machining centres and RMSMain job manager software, which is linked to Festool’s IK Office enterprise resource planning system. In addition, the company also supplied a Fanuc R-2000iC handling robot running on a linear rail. Also located within the cell are a Hexagon CMM, an Exeron die-sink EDM machine and an automatic washing system from Mafac.

Within the cell, a Roeders RXP 601 DSH primarily machines graphite electrodes, while a larger RXP 950 DSH is used mainly for hard machining. Materials include 1.2343 hot work tool steel and sometimes 1.2379 cold work tool steel.

Raw material is rough machined in the hardened condition (54-60 HRc) and subsequently finished while remaining in the same fixture. Compared with the previous procedure of roughing in the soft state, then hardening and finally finishing in a second operation, the new method is significantly faster and less expensive.

Renishaw’s net zero plans

After committing in November 2021 to a net-zero target by no later than 2050, engineering technologies company, Renishaw, has announced further plans to achieve net zero for scope one and two emissions by 2028 and have fully measured scope three emissions by March 2023. The company’s newly expanded sustainability team will be working to educate internal and external stakeholders about how they can better understand their environmental impact and collectively assist Renishaw to meet its science-based targets.

Productive added-value with high-speed mill

With the release of a 4 kW version of its MXCube, Datron is focusing on the high-performance machining of aluminium.

Since its initial launch in 2020, the Datron MXCube has gained a reputation for dynamics and precision. Its rigid structure and powerful high-frequency spindles with 4 and 8 kW power are tailor-made attributes for modern HSC strategies. Datron says that the combination of high chip volume and high surface finish therefore makes the MXCube a must-have for modern milling shops where unit costs determine the work cycle. As another point of note, the machine is a previous winner of the Red Dot award for its attractive design.

As of now, the Datron MXCube is also available with a 4 kW spindle and the automatic Datron Tool Assist tool changer offering 143 HSK-25 tool slots. At this performance level, it is particularly recommended for applications where a high number of sister tools is required. The Datron MXCube also convinces with its sophisticated chip management and is offered with an optional chip conveyor.

Datron says that MXCube is the right choice wherever high dynamics, high speeds and corresponding feed rates are required for the machining of aluminium and non-ferrous metals. In addition, the machine offers accessibility to all functional elements and thus simplifies not only the operation for the worker but also the maintenance for the service.

Like all Datron high-speed milling machines, the MXCube offers a large working area within a relatively small corresponding footprint.

Five-axis gantry-based profiling centre

The new top-of-the-range model from Elumatec is a breakthrough: as the first five-axis machine in a gantry design, the SBZ 155 profile machining centre raises the bar for automated CNC machining of aluminium and thin-walled steel profiles. With better performance than ever before and designed entirely to meet customer needs, Elumatec says that customers can accelerate their processes and open up new business segments.
The machine is expected to be available from Q1 2023.

“Our new top-of-the-range model gives industrial and metal construction customers a clear competitive edge,” says Elumatec CEO Paolo Bianchi. One example is the tool changeover times of the SBZ 155, which are minimised by the high rates of travel of the servo axes to guarantee optimum machining cycles.

Customisable equipment options give customers maximum flexibility to make their production processes even more efficient, and optional features include six-sided machining from below with an angle head and the space-saving gantry drive.

The SBZ 155 will be a particular asset for businesses which are thinking big in every sense: its large on-board magazines can be equipped with 14 standard tools, and depending on the individual configuration, up to six special tools and two 200 or 550 mm diameter saw blades can be used.

A gantry design and a machining area divided into two zones allow profiles with cross-sections of up to 1000 x 380 mm to be picked up and passed through, as well as flexible working in shuttle mode. Overall, the SBZ 155 delivers precise machining results even at high rates of travel, while its speed-regulated spindle ensures high process reliability even with quickly changing loads.
