VISION WIDE VB-2016 5-AXIS CNC gantry milling machine was manufactured
in 2013 in Taiwan. The machine performs precision machining of heavy
workpieces in three or even five axes, once the automatic swivel head
is mounted to the vertical spindle. The machine’s top-quality
cast-iron structure is rigid and resistant to bending stress, thus
perfectly dampening the vibrations and oscillations generated during
machining.
The VISION WIDE VTEC VB 2016 CNC gantry milling machine centre is
equipped with safety guards fitted around the entire machine with
sliding doors that open flush with the X-axis travel. Inside, there is
a large work table with a length of 2000 mm and a width of 1300 mm,
which is supported along the entire length of the longitudinal travel
and guided by two sliding guideways, making it possible to machine
heavy workpieces even when the table is unevenly loaded.
Two screw chip conveyors and one transverse caterpillar chip conveyor
with a discharge end at the end of the screw conveyors are arranged on
both sides of the work table. A state-of-the-art HEIDENHAIN iTNC 530
CNC controller with all the necessary functions is used to program the
machining modes and fully control the operation of the VISION WIDE
VB-2016 machine.
Movements in the X,Y,Z axes are carried out using sliding guideways
coated with Turcite B material, which ensures smooth movement and very
high rigidity. In order to guarantee accurate positioning under
changing conditions, the machine axes are additionally equipped with
high-quality HEIDENHAIN scales. A special cooling system eliminates
the effect of dilatation due to temperature rise, so the service life
of all ball screws and bearings is significantly extended.
The spindle of the VISION WIDE 2000 x 1600 CNC milling machine, with a
maximum power of 30 kW and a speed of 10000 rpm is located between two
hydraulic cylinders. The cylinders are connected to an accumulator
filled with compressed air to relieve the load on the Z-axis travel
motor. Feed is carried out along the cross beam by means of two
sliding guides placed symmetrically on both sides of the spindle.
The double column machining centre is offered with a wide range of
equipment, consisting, among others, of a rotary table with a diameter
of 800 mm, a RENISHAW RMP-60 workpiece probe, a RENISHAW TS 27R
contact tool setting probe and a magazine for quick tool changes in
the vertical position of the spindle with 32 positions. The total
weight of the machine is 25000 kg. The gantry machining centre has so
far worked a small number of hours machining small parts.
