Dörries VCE 2000 turning lathe in valve production
Tall, quiet and productive in cheese paradise
Tall, quiet and productive: The manufacturing experts at Mokveld Valves in Gouda
are proud of their new Dörries Contumat
VCE 2000 vertical turning lathe.
Mönchengladbach/Gouda,
Netherlands
A special machine tool has recently
appeared in Gouda: It is a Dörries VCE
2000 turning lathe, used by Mokveld
in Gouda to produce high-pressure
control and stop valves.
Mokveld Valves BV in Gouda had all
auxiliary units in the vertical turning
lathe (Dörries Contumat VCE 2000 /
200 MC FC So) enclosed in a housing
by Dörries Scharmann Technologie
GmbH, which is based in Mönchengladbach, Germany and is a subsidiary
of the Swiss-based Starrag Group.
”We no longer wanted our employees
to have to put up with the terrible
noise that came from the hydraulics“,
says Bart van den Bosch, Manager of
Production Engineering. ”But now
there is almost no noise.“
The ergonomic machine has been in
use since 2013. The unusual tower
structure is noticeable upon first
glance. The machine table (60 kW
drive capacity; 19,300 Nm torque)
can be used to process workpieces
that weigh up to 12 tonnes, with a
maximum height of 2,450 mm and a
diameter of up to 2,000 mm. The
Dutch company uses the VCE 2000
predominantly to machine cast steel,
chrome steel, duplex, super duplex,
Inconel and occasionally titanium.
The machine came with a pallet table
with a separate straightening table
and motor-driven alignment stand, for
more ergonomic and productive setup
of the next workpiece while another
workpiece is still in the machining
area.
As around 80% of the machining
operations are allotted to turning, the
tool magazine contains 50 lathe tools
that Mokveld has transformed into
300 lathe tools using a technological
trick with special holders. However,
the percentage of milling and drilling
operations also plays a crucial role:
The Dutch valve specialists appreciate
the fact that bores can now also be
manufactured on the machine in a
single clamping position. This reduces

the long machining times, as well as
costs and energy consumption.
Another special feature is the extended
retraction and stopping function:
If there are impending collisions, then
the tool is directed out of the machining
area and into a safe position. Mokveld
responds with the extended retraction
and stopping function in the event of a
power failure.
Reduced unproductive time: The Dörries
Contumat VCE 2000 vertical turning lathe
was fitted with a pallet table with separate
straightening table and motor-driven alignment stand. This makes the setup process
for the next workpiece more ergonomic and
productive, allowing it to be completed while
another workpiece is still being processed.
Company profile Mokveld Valves BV
The Mokveld Valves BV valve factory
(with 370 employees worldwide) was
founded as a small machine repair shop
in Gouda in 1922 by N.J. Mokveld.
The company has been manufacturing
its own products for 70 years:
It produces high-pressure control and
stop valves that operate on the axial
flow principle. The development of
axial valves received a major boost
with the discovery of the gas field in
Groningen, the Netherlands in 1950.
Mokveld initially produced valves for
the Dutch gas company Nederlandse
Aardolie Maatschappij (NAM) BV
from Assen, and then specialised in
high-quality, customer-specific valve
systems for the global gas and oil
industry. http://mokveld.com
