Peter Wolters is a company with a very strong
and historycal background, we've been founded in 1804.
We started in the garment industry,
and the company foundation was in Mettmann
nearby Düsseldorf, Germany.
And then 1970 we moved from Düsseldorf
to the North of Germany near by Hamburg
and have become the leader of high precision grinding machines.
Started in the 1930's with lapping systems
and have finally become one of the leaders
for high precision surface technology
in the field of semiconductor as well as general industry.
We are an international operating company,
so our costumers are placed around the globe everywhere.
We serve the field of semiconductor industry,
that is mainly silicon wafers for the chip makers
in the Asian market as well as the European market.
Another strong leader is basically the automotive industry,
but any industry basically that requires
high precision surfaces, high precision grinding solutions.
These customers can be served by Peter Wolters.
The voumard VM250 is a completely new designed machine.
The beginning of a new generation of machines that we introduce at voumard.
We have construced it from the scratch,
so this means every part is touched by our engineers,
starting with the machine bed,
which is using a new technology:
grey cast with cast and sand for vibration dampening.
It is the first in grinding technology.
Already used in other machine tools but not in grinding machines.
We have an extremely modular system,
allowing very many different options,
also adding options afterwards,
when the machine is already operating in the plant of the customer.
The main axes are with hydrostatic guides,
which means you can maintain the high precision
from the beginning on for many many years without any severe maintenance,
so there will be no wear on the guides which reduce the precision.
We have a lot of options that the machine take care of
all imaginable applications and the internal and external grining.
As a first at Peter Wolters Voumard
there's also an 'AUDI' option - auto diameter option - available,
which allows grinding simultaneously of the internal and the external diameters.
The lenght of the work pieces is maximum 1500 mm.
This means in here, between the grinding wheel and the chuck.
The maximum diameter, if you have the workhead in the back, is 430 mm.
And if you move the workhead completely to the front,
it's 550 mm outter diameter of the work piece.
The controller is very new, this controller is not only restricted to VM250,
it will also be parted to other machines of the Peter Wolters program.
So the 250 is the first and it will be spread over the whole product range,
similar to for example the touch pad of your tablet pc or your smartphone.
It uses a touch screen which allows you
to easily adapt your grinding programs to your needs
without long learning.
It is by intuition, you can just feel, you can see,
what the touch screen expects of you.
You can select between modules for example
cylindrical internal grinding, conical internal grinding or thread grinding.
So this will be manual set.
You can easily select from a kind of library.
Then the feeding in the grinding paramteres is easily done
in a dialogue without thinking too much,
so everybody who has experience in grinding,
will very very quicly be familiar with the system.
The main target for this machine are the machine tool manufacturers.
For example spinner manufacturers
who want to grind spinner axes, spinner casings.
Other machine tool suppliers who want to
grind part of their machines for building their own machine tools
like milling machines, turning machines etc.
It's also the hydraulic field, automotive, avionics,
very many users are looking for touchscreens
for making hydraulic parts for aeroplanes or ships.
And all industries which are machining large parts
up to 1500 mm long and up to half a meter diameter.
