mandrel cutting machine<br />
p r e c i s i o n m a c h i n e s f o r c u t t i n g p l a i n s e c t i o n g a s k e t s<br />
The basic idea: Metzner mandrel cutting machines of the SR<br />
range are precision machines for cutting gasket rings from<br />
moulded or extruded tubes. The distinguishing features are the<br />
unique cutting method and the high cut quality.<br />
To produce the plain section gaskets, rubber tubes – already cut to<br />
length – are stretched onto mandrels. Loading and unloading of the<br />
tubes onto the mandrels is done quickly by a special unit and without<br />
any particular skill being required. Then the mandrels are automatically<br />
clamped between rotating centres and the production is started.<br />
A knife carriage travels along the tubes, cutting the rings to the required<br />
length, either with stiletto-type tools or circular knives.<br />
This process fully brings together high output and the highest cut quality.<br />
The use of the most modern servo-technologies makes the SR machines<br />
even more versatile: knife penetration speed and carriage advance<br />
are fully free-programmable – for optimal processing of materials with<br />
different characteristics. The SR range includes two and seven-spindle<br />
machines, so that Metzner can offer you the most economical solution for<br />
different capacity requirements.<br />
