Retrofit and sale of CORREA A25 and A30 fixed bed milling machines for companies in France

The CORREA A-25 and A-30 bed type milling machines are noted for their dual guideways and robust structure, specifically designed for applications requiring a heavy-duty chip removal capacity. All these milling machines feature slideways with steel inserts, bronze counter guides on the Y axis, and resin counter-guides on the X and Z axes. A unique feature of the A-30 model is that, on the X axis, it is equipped with roller slideways and linear guideways for the table travel. The three retrofitted milling machines sold to companies in France all feature a travel of 3 m on the X axis and 1.2 m on the Y axis, whilst the travel on the Z axis is different for each of the three models.

The first of these milling machines to be sold was a CORREA A30/30 which featured an automatic UDG-40 type auto-indexing head with indexed positions of 2.5º, a 30-pocket tool changer, chip removal and a vertical travel of 1500 mm. This A30/30 CORREA, originally built in 1997 and equipped with a TNC-426 Heidenhain control, was retrofitted by NC Service and installed in France in a company with more than 20 years´ experience in the design and machining of mechanical parts and sub-assemblies, whose production methods are focussed on CNC turning and milling, grinding and welding.

The second milling machine, also sold to a company in France, was another CORREA A30/30 model, featuring a U-40 manual head and with a travel of 1000 mm on the Z axis. The machine was also equipped with a Heidenhain TNC-426 control, yet with no automatic tool changer like the one above. It was installed in a company with more than 30 years´ experience in performing special work involving machining, mechanical welding, tools and special machines.

The last milling machine to be recently retrofitted by NC Service for a company in France was installed in a company dedicated to the development, design and manufacture of services and solutions to meet the needs of its customers. A CORREA A25/30 milling machine was supplied to this company, which was installed by NC Service after being retrofitted in Burgos. It features a UDG type auto-indexing head with indexed positions of 2.5º and a 30-pocket tool changer. It also has a Heidenhain TNC-426 control and an HR-410 electronic wheel, offering a travel of 1000 mm on its Z axis.

The robust structure of these CORREA A-25 and A-30 milling machines, with generously-sized, strongly-ribbed, alloyed cast iron modular components, means that all these machines offer excellent performance for work involving heavy-duty chip removal. Moreover, the detailed refurbishment work performed by NC Service on these milling machines, prior to sale, ensures that its customers can obtain a same-as-new performance for these milling machines, in addition to their excellent precision and high dynamic performance.
