With the Dualmaster series, FPS Werkzeugmaschinen, Germany, is launching the new FPS 425 and FPS 630 universal milling machines. They will replace the previous FPS 420 and 620 as of January 2022.

The new three-axis universal milling machines Dualmaster from FPS have remained virtually the same in width and depth as their predecessor series. Nevertheless, the developers have, among other things, increased the travel of the Y-axis from 350 mm to 450 mm. The basis for this is a dovetail guide with double contact surface.

In the X direction, FPS has extended the travel by five (FPS 425) and ten millimetres (FPS 630) to 425 mm / 630 mm. In these axes, as well as in the unchanged 400 mm long Z-axis, the company now uses roller guides. In combination with the new drive generations from Siemens or Heidenhain, the Dualmasters achieve rapid traverse speeds of 10 m/min in all linear axes, which is twice the previous values.

Equipped with absolute path measuring systems, the accuracy of the motion control in the linear axes increases at the same time. Accordingly, circular forming tests can be reliably performed with a precision of less than one hundredth of a millimetre. The spindle power has also increased. While a maximum of 7 kW was possible with the previous models, the Dualmaster now has spindles with up to 16.3 kW.

As a further innovation, FPS has redesigned its cabins for the M-NC series and completely enclosed the Dualmaster machines. This means that no gaseous emissions escape even when cooling lubricants are used. When milling manually, however, it is still possible to open the enclosure wide so that the machine operator has a clear view of the workpiece.

When it comes to controls, the Warngau-based machine builder remains true to its previous suppliers and also relies on the latest generation of German high-end CNCs from Siemens or Heidenhain for the Dualmaster series. This means that they are available with Sinumerik One PCU 1740 or TNC 620 FS.
