Mandrel Cutting Machines

Metzner mandrel cutting machines of the SR range are precision machines for cutting gasket 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.
