Matching machine-tool investment to the intended applications is something Crediton-based subcontractor Adaero Precision Components has done well over the years. The latest addition to its capacity, a Wele AQ1265 three-axis vertical machining centre with Nikken rotary table fourth-axis, is no exception.

The provider of the Taiwanese-built machine, sole UK agent Whitehouse Machine Tools, has delivered numerous other machining centres to the subcontractor during the last decade, sourced from Brother and Akari. So Adaero had confidence this time around in the supplier’s advice, despite never having heard of the Wele brand.
On this occasion the requirement was to replace an ageing, four-axis machining centre that had become unreliable.
Mainly, the new machine has been devoted to carrying out cycles of relatively low complexity on simple parts, such as large aluminium plates. A moderate level of investment was appropriate in a machine fulfilling this type of work. Nevertheless, Dimensional accuracies of typically ±0.01 mm need to be held. Furthermore, despite three-quarters of output from the factory being aluminium parts, the machine has to be robust to perform arduous cutting cycles, continuously, every day from 08:00 to 17:00.
David Smith, Adaero’s finance manager says: “The Wele met our requirements and cost significantly less than other machines we reviewed. Our engineering director Jack Wilson-Hill visited a Whitehouse customer to see a similar machine in action and was impressed with the rigidity of build. The fact that Wele is part-owned by Toyoda, a Japanese manufacturer of top-end machine tools, also pointed to production equipment that was of high quality, added to which the AQ1265 was competitively priced, so we placed the order.”

Numac Engineering, a subcontractor which secures more than half of its business from the oil and gas sector, has ordered a Hermle five-axis, trunnion-type, mill-turn centre to strengthen its prismatic machining capability and simultaneously add extra turning capacity.

Kingsbury, sole agent for the German machine builder, will install the Hermle C42UMT in the customer’s Stalybridge factory in October 2019.
The Hermle C42UMT will also allow the contract machinist to take on more complex work in the aerospace and motorsport sectors. A wide variety of metals is already machined on site, encompassing most grades of stainless steel, as well as exotic materials including titanium and nickel alloys such as Hastelloy and Incoloy.
Andy McLaren, managing director at Numac, says: “We have four-axis horizontal and vertical machining centres here, but are keen to add full five-axis milling and drilling, both to increase the complexity of parts we can produce and reduce the number of set-ups needed for 3+2 axis work.
“The Hermle’s torque table will cut the number of separate operations even further on some of our mill-turned components, as we’ll be able to avoid a separate clamping on a lathe,” he continues. “We have a number of oil and gas parts earmarked for such a process improvement, and estimate that typically the number of set-ups will be halved, resulting in major efficiency and productivity increases.”
Some 18 months were spent by McLaren researching five-axis mill-turn centres and says he opted for the Hermle primarily due to its superior turning capability, the table having a maximum speed of 800 rpm and the ability to turn components with the trunnion positioned at any angle.
