Traditionally a three-axis vertical machining centre user, Singer Instruments in Watchet installed its first five-axis CNC machine at the start of 2019 to streamline the manufacture of aluminium components.

The German-built Spinner U5-630, a 40-taper machine, was supplied through sole UK agent Whitehouse Machine Tools, and is equipped with high-pressure coolant through the spindle and a separate clean tank, as well as Blum spindle-mounted workpiece probing and a tool-setting probe.
Cycle-time savings have been dramatic and there has been a considerable reduction in the number of set-ups needed across a raft of different parts. This positive outcome is a result of using the two additional rotary CNC axes provided by the swivelling trunnion and rotary table to reposition components automatically. In one case, a table for Singer Instruments’ Rotor automated screening instrument used in the biological sciences sector, is produced in three set-ups, whereas previously it required nine separate prismatic machining operations on a three-axis VMC. More typically, components formerly needing six operations are now produced in two.
Investment in five-axis capacity was instigated by Steve Maconnachie, CNC machinist at Singer Instruments. Maconnachie previously ran his own subcontract machining business with his brother in the Midlands and had used five-axis technology for many years. He was familiar with all the leading makes of machine, many of which were reviewed before deciding on the Spinner purchase.
“Some of our components are tightly toleranced to ±5 µm, so we maintain the temperature of our production area to within a couple of degrees,” he says. “It’s true that many of the five-axis machines we considered could hold this tolerance, as does the Spinner, whose price was also competitive. It was little more than half the cost of one of the other production centres shortlisted.”

When Peterborough-based Rivercircle invested in one of the first XYZ UMC-5X gantry-style simultaneous five-axis machining centres just over 12 months ago, its ambition was to gain efficiency by transferring work previously performed on three- and four-axis machines.

Such was the company’s success in doing that, it has won numerous new contracts for five-axis work, resulting in the arrival of its second UMC-5X.
“We had no work that demanded full five-axis capability when we bought the first XYZ UMC-5X, but knew we could reduce set-up time and cycle time by moving work from other machines,” explains Paul Langan, Rivercircle’s production manager. “Furthermore, we had no expectation of keeping the machine busy 24/7, but as word spread, customers began to recognise the capability that we now had, and work kept coming in.”
The influx of orders from existing and new customers for dedicated five-axis work meant that additional capacity was required. However, due to the success of the first machine from XYZ, there was no reason for Langan to look anywhere else for the second.
“Work is continuing to move towards five-axis machining and, with the two XYZ UMC-5X machines, we can combine operations and become far more efficient, which will ultimately lead to more work as we are more competitive,” he says. “The ease of use of the machines, with the Heidenhain control that we are familiar with, along with support from XYZ Machine Tools, made our decision to double-up straightforward.”
The arrival of the second XYZ UMC-5X was enhanced by investment in several seats of Mastercam five-axis software to ensure there were no bottlenecks in processing the increased amount of work generated by the additional machining capacity.
