NC Service shows the refurbishment process of a CORREA CF17D. Do you want to see the video?

This is a bed type CORREA CF17D milling machine, manufactured in 2001, with a Heidenhain TNC-426 control unit and an universal milling head. Longitudinal axis traverse of 2000 mm and 800 mm on both the Y and Z axes.

It was fully mechanically refurbished by NC Service at its facilities with initial disassembling of main components. After this, cleaning, sanding, priming and painting were carried on. In the meantime, motors, drivers, power cabinet and CNC were inspected, as well as grinding and adjusting of the three axis of the machine (X, Y, Z).

The milling head was also thoroughly retrofitted by NC Service, with full dismantling and revision of elements, changing bearings and rectifying the principal axis. This is one of the main elements from a milling machine which most suffers during its useful life, so for this component this reconstruction process is of special importance. Requested by final customer, a coolant through spindle system of 17 bar was also installed in this milling head, including new deposit and coolant pump.

As usually, after this refurbishing process, geometry protocols established by manufacturer were carried on in order to certified its mechanical accuracy.

And finally, installation and commissioning were done at customer’s facilities.

This refurbishment process and final result could be seen at the following video.
