Nicolás Correa recently participated in the latest edition of the BIEMH exhibition in Spain, showing its Correa Fox model with UAD milling head and a Norma model with rotary table.

During the event, Nicolás Correa took part in the 13th National Awards for Innovation in Digital and Advanced Manufacturing Technologies, entering the category of ‘Machine Tool, components, accessories and tools innovation’ with its UDX milling head.
The UDX is a mechanical transmission milling head with rotation every 0.02° thanks to the double Hirth coupling system (patented worldwide). UDX heads are able to perform 10,000 rpm, and were featured at the show on the Fox 50 model.
Consisting of two 45° bodies, the UDX is designed and built to withstand heavy-duty cutting conditions, as well as semi-finishing and finishing work with precision and speed, says the company. The Fox 50 also includes a 60-station automatic tool changer and a Heidenhain TNC 640 control. Furthermore, Correa says that its total symmetrical design improves the geometry of the machine, which remains more stable when faced with temperature changes.
The Correa Norma is a flexible machine suitable for roughing and finishing operations. The model exhibited at BIEMH was a Norma 25 with integrated rotary table. Also presented was the Correa Delfos 4.0 system, which allows monitoring based on the cloud, automatically recording and analysing machine data to improve efficiency and the production process.
According to AFM Advanced Manufacturing Technology, the machine tool sector has recently achieved a record annual turnover in Spain, at €1690m.

A Starrag Bumotec s181 machining centre is enabling a producer of ‘traditional’ turned parts to not only finish-machine a multi-operation component with interconnecting holes to a burr-free state and with high levels of roundness and surface finish, but allowing the company to welcome new business where effective and efficient single set-up, multi-operation workpieces are required.

The Fanuc-controlled s181 turn-mill centre – which effectively has nine CNC axes in total – was installed to produce a distributor for a respiratory protective device; the component that connects an oxygen bottle to a respirator mask (as used by the fire service).
Produced from a special aluminium alloy (AlSi05) forged blank, the workpiece presents a number of machining demands before it is anodised – in particular the production of a hole (H7) that is drilled to a tolerance of 14 µm and must
not have burrs on the interconnecting channels. The Bumotec inserts the blank automatically then processes all six sides of the workpiece.
One critical aspect of producing the component is the fact that the initial blank is forged to a high tolerance, so a specially-designed clamping system – one that will hold the part rigidly but without damage or deflection – has been developed and adapted to the machine.
With an HSK40 (30,000 rpm) spindle, the Bumotec s181 can, however, produce very small components (up to 32 mm) to 1.5 µm, and it is this quality that the new user is adamant “will position the company internationally for the production of high-precision components”.
