Hull subcontractor selects Victor

Hull-based Rubitec Engineering Ltd has recently purchased a Victor Vturn NP20 CNC turning centre from GM CNC Machine Tools, the first Victor machine on site.

Andy Shores, managing director of Rubitec Engineering, says: “The machine has cut our run times and it’s a nice feeling to have a level of support from GM CNC that ensures with just one phone call, we can have everything we need.”

Commenting on why the company needed the Victor Vturn NP20, Shores says: “We had an ageing turning centre of similar capacity and capability to the Victor, but it was unreliable. And even though we service a lot of our own machines, the maintenance costs were escalating. We needed a new machine with a compact footprint and Victor fitted the bill.”

Looking closer at the specifications of the Victor Vturn NP20, it has a 52 mm through-spindle bar capacity. However, with the slant bed construction, the turning centre offers a 650 mm swing over the bed, providing 320 mm maximum turning diameter.

“The stability and kinematics of the Victor Vturn NP20 have increased productivity by at least 20% compared to our other machines,” says Shores. “In addition, the rigid tool turret and powerful coolant supply have improved the tool life on our milling tools by over 30%, while the overall machine construction has also helped to increase tool life for turning tools by 30%.”

Concluding on the service from GM CNC, Shores says: “To provide a score, I would certainly give GM CNC 10 out of 10. We trust GM CNC, its staff and levels of service implicitly.”

Positivity from subcontractors

The UK’s subcontract manufacturing sector is emerging from lockdown with exceptionally strong sales pipelines, according to a cross-section of industry leaders. For instance, Chris Shield at Leicester-based Shield Group, says: “The pipeline is very strong and we’re feeling a lot more positive compared with six months ago.” Andrew Whitham at Manchester-based Brooks Ltd agrees, adding: “We’ve enjoyed a period of sustained growth and investment despite the challenges of COVID and lockdowns…the order book is very strong.”

The story is similar at Stoke-based John Hyde Engineering. “We’re more positive than six months ago and the pipeline is looking increasingly robust,” says John Hyde. Alan Mucklow, managing director UK and Ireland sales and service at Yamazaki Mazak, says the optimism of the subcontracting sector is a much-needed boost for UK manufacturing. “It is very striking, when I talk to customers, how positive the outlook is.”

Manufacturing outlook improves

Manufacturing output volumes in the three months to March improved to broadly flat, which marked their highest balance since May 2019, according to the CBI’s latest monthly Industrial Trends Survey of 321 manufacturers. Manufacturers now expect output to pick up rapidly over the next three months, with expectations at their strongest since August 2017.

Total orders books improved to their highest balance since April 2019, surpassing their long-run average, while export order books strengthened to fall broadly in line with their long-run average. Manufacturers also anticipate output price growth will accelerate quickly in the next quarter, the strongest expectations since February 2019.

Investing to weather the storm

Despite the pandemic and subsequent lockdowns and restrictions, Newbury-based precision subcontractor Cadmatic Engineering Services is demonstrating its resolve and ambition by investing in a new Doosan multi-tasking lathe from Mills CNC.

The 8” chuck Lynx 2100LMB is equipped with a 15 kW/4500 rpm main spindle, driven tooling capability (3.7 kW/6000 rpm), a tailstock and the latest Fanuc i series control with a 15” touchscreen. As part of the investment, the Lynx lathe also features a CNC bar puller.

Since its arrival in December 2020, the Lynx 2100LMB has been machining a range of press tool components, such as pins, pillars and shanks, for press tools used in the automotive industry. The Lynx is also machining a diverse range of press tool replacement parts, as well as associated jigs and fixtures and, increasingly, low-to-medium volume production of small, high-precision parts.

Says director and co-owner Mark Humphrey: “We needed to improve our turning capabilities but, rather than just acquire additional like-for-like capacity, we decided to invest in a compact, multi-tasking machine that, with its integrated driven tooling functionality, could machine precision parts in one hit – helping us reduce cycle times and lead times.

“I particularly like the Doosan machine’s fast turret indexing, which helps reduce cycle times, and the machine control’s 15” touchscreen, which doesn’t just look the part, but improves visibility and facilitates fast and more reliable data input,” he adds. “Mills were able to supply the Lynx lathe with a large Grippall CNC bar puller, which has enabled us to use the machine for bar work and run it unattended during the day shift.”

CMM offers more accuracy and speed

UK-based CMM manufacturer LK Metrology has designed a new, more efficient air bearing and carrier, which the company now fits as standard to its Altera-C range of ceramic-bridge, multi-sensor CMMs. By significantly augmenting the pre-load on the structure, stiffness has been uprated without making the guideway thicker, leading to more precise motion control.

According to LK, the results are higher measuring accuracy, whether a touch-trigger probe or scanning probe is used, coupled with the possibility to increase speed of operation and raise inspection efficiency. The Altera-C machines, which are available in three sizes with measuring volumes of 700 x 650 x 500 mm, 1000 x 650 x 500 mm and 1000 x 650 x 650 mm, carry a 10-year accuracy guarantee covering dimensional stability.

In terms of speed, all machines now accelerate at 1900 mm/s2, representing an increase of 15% for the two smaller models and 20% for the largest model. Velocity is up by 38% across the product range to 720 mm/s. As regards accuracy, the maximum permissible measuring error on all machines is now 1.7+L/333 µm when measurements are taken of a feature L mm in length (between 18°C and 22°C), irrespective of whether a TP200, SP25, TP20 or PH20 probe is used. This performance represents length measurement accuracy improvements of 22%, 22%, 32% and 43% for the four respective probes, while maximum permissible probing error is also better, as is repeatability of measurements (by 15%) when using a PH20.

Optimisation of the pre-loaded, wrap-around air bearing configuration was feasible due to the inherent rigidity of LK’s ceramic guideway, which allows it to maintain structural integrity under extreme conditions.
