EDITORIAL ROUNDUP

Free online courses at the Grinding Academy

United Grinding and Titans of CNC, a manufacturing group of part-makers, influencers and educators, have collaborated to launch the all-new Grinding Academy. Much like Titan’s existing machining and aerospace academies, the Grinding Academy will offer free online courses that teach and train the next generation of machinists. Titans of CNC has four United Grinding machines on its shop floor in Texas: a Blohm Panomat XT profile grinder; Studer Favorit and Studer S41 cylindrical grinding machines; and a Walter Helitronic Vision 400 L tool grinder. These will be the first machines used to create content for the Grinding Academy.

AWI donates to Acorns Children’s Hospice

A leading hospice that cares for more than 900 families every year is the latest recipient of the ‘Wired for Good’ campaign run by Alloy Wire International (AWI). The UK manufacturer of round, flat and profile wire has donated £7500 to the crucial work of Acorns Children’s Hospice to help it continue providing respite, short breaks, end-of-life and emergency care across its three locations in Birmingham, Walsall and Worcester. Bosses at AWI have been long-term admirers of the charity and the way it provides a homely environment where children can take part in a range of fun and therapeutic activities, from arts and crafts sessions to hydrotherapy.

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.
