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