Cross Rail

- high quality aged cast iron components.

- the portal is made of two columns which are mounted
rigidly to the bed. At the upper end they are linked and
stiffened by a heavy cross rail and support members for
lager machines, the smaller ones are monoblock.

- high precision guideways and trapezoidal lead screw
for cross rail positioning along the columns.

- hydraulic clamping & unclamping of the cross rail.
- hardened steel inserts on the cross rail.

Table and workholding support

- the table is made of special cast iron and is heavily ribbed

- table motion on the bed is either by cross roller bearings or
optional hydrostatic bearing

- the table is driven by a gear box and the speed is infinitely
variable

- in milling operation, (optional C-axis) the table is driven by
means of a feed gearbox, which utilizes a duplex worm gear and
hydraulic backlash compensation
