MACH hailed as roaring success

The UK’s national event for inspiring and connecting the manufacturing industry has once again been hailed as a triumph, with thousands of visitors filling the five halls at the NEC in Birmingham over the week-long show in April. The 2024 edition of the exhibition saw a 6% increase in the number of visitors meaning the full attendance of the event is rapidly approaching 30,000 people.

A highlight of the seminar programme was the launch of the MTA’s latest ‘True Impact of Manufacturing Report’. The report reveals the significant positive impact that manufacturing has on the UK economy, which is far greater than many think. Key findings of the report include: manufacturing accounts for £518bn of UK GDP and supports 7.3m jobs; ‘making things’ accounts for 34.5% of all UK goods and services exports; and themedian wage in manufacturing is 11% above the national average.

Driven-tool CNC turning centre launched

Hurco introduced a new range of four driven-tool CNC turning centres at the MACH 2022 exhibition, during which the 8-inch chuck version was exhibited. At the 2024 show last month it was the turn of the 10-inch chuck variant to appear: the TMX10MYSi. All models include a programmable Waxis to position the tailstock or sub-spindle.

The turning centres offer higher specification and performance than the established TMi and TMMi models. Among the major differences are higher power and speed plus a larger, heavier machine frame and the addition of a Yaxis to allow more versatile machining.

Notably, the servo-driven turret carries 12 VDI 40 radial tools rather than axial tools (as on the/TM Mi range). Each station offers a maximum rotational speed of 5000 rpm and a peak output of 6.3 kW at 2190 rpm. Hurco’s control software allows users to take advantage of the manufacturer’s proprietary conversational routines for milling operations, making the package attractive for small-volume production requirements.

Two smaller capacity Hurco CNC lathes with 8-inch chuck capacity were also on show, the TM8i and the TM8Mi with axial driven tools. These latest models have a larger spindle bore than their predecessors, as well as roller guideways and a more compact footprint. As a further point of note, the improved control features concurrent programming, estimated runtime, error check and recovery restart, and enhanced performance during rigid tapping.

High-specification lathe at competitive price

At the MACH exhibition in Birmingham, UK, last month, NCMT showcased a number of Okuma turning centres, including the competitively priced Genos L3000-e-MYW. The display saw the machine fed automatically with shaft-type parts by a Cellro CoMate collaborative robot (cobot). The maximum turning diameter of the Genos L3000-e-MYWis 300 mm while speed of the 22 kW spindle is up to 3800 rpm, all in a compact footprint of 2.5 x 1.9 m.

This 6-tonne turning centre featuring sub-spindle and a 12-station turret with Yaxis and live tooling offers robust construction. An integral spindle motor and rigid guideways make it suitable for the precision machining of many materials, including exotic alloys. User-friendly features include a separate coolant tank for quick servicing, and easy spindle access to speed maintenance and machine set-up, and reduced chip accumulation for less machine downtime during removal.

Okuma’s One-Touch IGF is an option in the OSP control. The One-Touch IGF allows users to describe part geometry including diameter, length, grooves and threads using simple commands, from which the system draws the defined shape and then develops the part program automatically.

Also on the stand was an Okuma MultusU3000 multi-tasking lathe with a 240° swivelling B-axis head and HSK-A63 (optionally Capto C6) 12,000 rpm/22 kW spindle for turning or milling components up to 1500 mm between centres. The tool magazine has 40 stations as standard, but is optionally available with a capacity of 80 tools.

Okuma’s MultusU3000 features Okuma’s own linear scales for high-accuracy positional feedback. Servo motors deliver feed rates of up to 50 m/min in the X and Z axes, and up to 40 m/min in the 250 mm Yaxis. Together with the Caxis on the main spindle, the machine is capable of fully interpolative five-axis (X,Y,Z,B,C) machining of freeform surfaces.

Showtime for Hanwha sliding-head lathes

To showcase the breadth of its machine tool offering, Dugard gave the Hanwha brand of sliding-head turning centres prominence on its stand at the MACH exhibition in Birmingham, UK, last month.The XD10, XD20 III and XDI 32 modelstook centre stage.

The smallest of the three, the Hanwha XD10,offers 10mm bar capacity for the mid-to-highvolume machining of small components. With a 15,000rpm/3.7kW spindle and eight front and six back-end turning tools, the XD10 is a flexible proposition. The machine also provides four ER11 front-end tools and four ER11M cross-drilling tools with eight ER11 sub-spindle back-working tools.

Next to the Hanwha XD10 was the larger Hanwha XD20 III. Available with FANUC or Siemens control, the XD20 III is for machining both short and long components with its extended Z1-axis stroke of 240mm and Z2-axis stroke of 286mm. With five cross-drilling stations as standard and a Y2 back-tool feature, the XD20 III demonstrates high productivity levels. Flexibility comes from the presence of six OD tooling stations, five ER16M positions for front and back working, five ER16 cross-drilling positions (with an additional two for off-centre drilling),and eight back-end tools configured as four fixed and four driven positions.

The third Hanwha machine on the stand was the XDI 32. The largest of the three Hanwha machines at MACH, the XDI 32 provides strong performance characteristics that stem from a robust machine construction, providing the base for precision, repeatability and smooth surface finish. The 32 mm diameter capacity machine features a 6500rpm sub-spindle and up to 26 tools.

Bumotec solves medical production puzzle

Ireland-based Dawnlough Precision is a 110-employee subcontract manufacturing business that has travelled a relentless journey of growth since it started manufacturing tooling for the aerospace and medical industries back at the start of the millennium. This ascension has arrived through an aggressive growth strategy and investment in high-end machine tools, including two Bumotec 191neo turn-mill centres from Starrag.

“Our core business in the medical sector predominantly focused on vascular work and, from this, we’ve expanded our offering,” explains Keith Kennedy, aerospace production manager. “We now produce an array of components for our robotic-assisted surgical [RAS]customers, as well as consumable instruments.

It is here that the search for a suitable machine led Dawnlough to purchase its first Bumotec 191neo FTL-R in June 2022.

“We needed a machine that could offer accuracy of 2-3µm on production runs, short cycle times and incredible efficiency because it’s a very competitive market,” continues Kennedy. “We visited many companies offering high-accuracy machines, but it’s only as you look closer and purchase a machine for this type of work that you really see the added value they bring.

“Some of the functions of the Bumotec, such as thesoftware for monitoring the machine, the cutting load, the contact cutting time and the large 90-tool ATC are incredible.It was a huge investment and an unknown risk, but the Bumotec ticked all of our boxes.”

Following the success of the Bumotec 191neo in FTL-R configuration, the Galway company added a second Bumotec 191neo in March 2023. Supplied in FTL-PRM configuration, the subsequent Bumotec 191neo features complete automation and a 20-position pallet station for lights-out production.
