The success of a Heckert HEC 800 X5 five-axis machining centre for the machining of a titanium part at Hyde Group’s Hollygate Aircraft Components has subsequently led to the installation of a similar Heckert machine at sister Group company Victoria Production Engineering, for processing stainless steel components.

Both X5s, supplied by Starrag UK, have enabled the companies to ‘work smarter’ by introducing twin-pallet machining instead of single-station, three-axis working. This strategy provides for high utilisation levels as the machines’ twin pallets enable extended hours of machining.
In addition, not only do attributes such as integrated spindle monitoring, high-pressure coolant and effective swarf removal allow for unmanned working, but improved tool-holding stability has led to improved tool life.
Both companies are part of the Aero Products division of the Hyde Group – the northwest-based engineering service provider that specialises in design, manufacture, tooling and support for customers that include Airbus, BAE Systems, Boeing, Embraer, GKN Aerospace, Leonardo and Rolls-Royce.
Paul Mellor, divisional technical director, explains that rising demand for the titanium workpiece at Stockport-based Hollygate spurred the search for “an improved way of working where we could effectively gain more from the same” in terms of replacing machine-for-machine with regard to floor space and manpower requirements, which led to the installation of the initial Heckert HEC 800 X5.
Mellor also outlines how similar process improvement strategies were employed for the stainless steel workpieces being machined by Victoria Production Engineering in Manchester.
“Two aspects were of particular significance,” he says. “These were: Starrag’s introduction of special hydraulic ‘sleeve’ clamping [via the machine’s hydraulics system] to consistently hold – yet not deform – the thin-wall tubular parts; and the application of long-reach angle milling heads on the Heckert HEC 800 X5.”
