The travelling circular knife machine CCM 6 cuts rigid profiles and tubes accurately to length. The CCM 6 achieves very long processing times of several seconds for excellent "final trim quality" thanks to a standard servo linear drive for the tool carrier, and at the same time extremely short cycle times of less than one second for machining short parts at high line speeds. Added to this is the servo linear drive for circular knife feed with different feed speeds for different material sections, e.g. a gentle material penetration or knife exit with low feed to reduce burr formation. High speed ranges As far as the knife speed is concerned, we offer you outstanding possibilities of alternatively 2,000 – 6,000 rpm or 4,000 – 12,000 rpm. This means that there are no limits to the use of various types of circular knives, including clamping and grinding in continuous operation. Our product videos will give you an insight into the machining process.

The modular system of the MBS series is available in three sizes. The MBS 200 is the "medium-sized" of the three models and processes materials such as tubes and profiles up to 190 mm wide. Depending on the material size, further machine elements such as type and number of cutting tools, length and width of the belt feed, control, feed, running direction, coating material of the conveyor belts and base frames are selected. Metzner "MBS series" cutting machines stand for outstanding flexibility when machining flexible and semi-rigid profiles made of rubber and plastic. With different cutting methods and machine components, cutting machines are created which can be individually adapted to customer requirements and are made available in the shortest possible time with hardly any development effort.

Where pneumatic tools of the MBS series reach their performance limits, the eccentric cutting machine opens up new possibilities in cutting performance. Instead of a pneumatic cutting tool, the Metzner ST 25 uses an electrically driven eccentric mechanism that carries a punching blade. This enables us to increase the performance of the die-cut into completely new dimensions, of up to 800 cuts per minute. An agreeable side-effect: With the electric drive for the cutting tool, the ST 25 works very quietly – which is why customers with low-noise working environments also like to opt for this model.

The modular system of the MBS series is available in three sizes. The MBS 400 is the “largest" of the three models and processes materials such as tubes and profiles of up to 390 mm wide. Depending on the material size, further machine elements such as type and number of cutting tools, length and width of the belt feed, control, feed, running direction, coating material of the conveyor belts and base frames are selected. Metzner "MBS series" cutting machines stand for outstanding flexibility when machining flexible and semi-rigid profiles made of rubber and plastic. With different cutting methods and machine components, cutting machines are created which can be individually adapted to customer requirements and are made available in the shortest possible time with hardly any development effort.

Metzner has developed a fully automatic processing machine with outstanding cutting quality and great length accuracy for steel cable wires of up to 20 mm diameter. The steel cable wires are fed by a motorised feeding device in combination with a contact-free loop control. Then, program-controlled and positionally accurate marking tapes are applied to the steel cable – with a cycle time of less than two seconds. In addition, a wax printer marks all the fastening and processing points that will be required for subsequent processing. This labelling method is carried out in a continuous process. The cut is then made using a special cutting process. Precise length accuracy is achieved by a special laser measuring system. A material stacker with a storage area of up to 12 metres ensures that the steel cable wires are deposited in an orderly manner. All cut steel rope can be stored and sorted according to length to allow it to be removed at a later point.

This special Metzner development is able to process cable wires with a diameter of up to 28 mm. The cycle time for this is 2000 mm / 35 seconds. The processing steps include long slitting, sawing, circumferential cutting, stripping, brushing and depositing. An integrated ink jet printer labels the cable wires with information or markings. As the heart of the processing method, Metzner uses a newly developed stripping head that combines a rotary cut with a powerful clamping and simultaneous rotation of the material. This enables a high-precision, multi-stage radial cut through the various layers of material. Microscopic quality inspection confirms that the processing is flawless with no scratches, pressure or abrasion marks. In addition to the high machining quality, the machinery also offers special precision: both the overall length and the machining position are maintained with an accuracy of 0.2 mm. The machine can process cable wires with diameters up to 28 mm.

The specially developed production line can unwind, label, roughen, cut to length, strip, wind, bind and automatically deposit the cable wires. The material to be processed is unwound by a motorised unwinder and fed to a thermal transfer printer via a straightener. The latter prints the cable with two QR codes and a serial number. This ensures that each cable can be identified throughout the entire processing and manufacturing process and assigned to the stations which have already passed through. This traceability offers great advantages – for example in the diagnosis of faults. The cable then passes through a roughening station, which lightly roughens the material surface so that the connector overmoulding adheres better later on. An AM 3550 from Metzner Maschinenbau cuts to length and strips the cable, which is then transported to the winding station and onwards by a gripper to the binding machine. The latter winds the cable to form a cable ring.

Plastic-coated steel cablestrands are cut to length using a special shear cut module and then stripped with the cutting module of the AM3500 without the wires "jumping open".Bare steel cable wires are transported by the modified AM 3500 directly to the special cutting machine, which is coupled between the AM 3500 and the material stacker and which cuts the material to length by a thermal process. Due to the special electric welding process used here, the individual wires do not twist up during cutting, and a smooth rope start and a smooth rope end without thickening are produced. Long steel cable wires/strands are placed in a tray after processing, while short pieces of material fall down a chute into a collecting container. With the high-performance solution developed by Metzner, the customer can process different types of material in different processes. Further advantages of the machinery are high precision, high quality, an increase in productivity and lower personnel costs.

The Metzner special development department produces endotracheal tubes with high precision and cleanliness. This is ensured, among other things, by processes such as automatic loading, alignment and positioning of the tubes, processing by seven consecutive work stations and automatic quality control by sensors. Our product video will give you an insight into the machining process. Maschinenbau GmbH has sustainably reduced the production costs of the end products and created additional production capacities with a fully automatic production system for endotracheal tubes.

The special Metzner development is a fully automatic machinery consisting of a contact-free loop control, an automatic cutting machine and a crushing station with storage system. It can produce polystyrene pipettes with diameters from 4 to 25 mm and lengths from 100 to 700 mm. The extruded material is first scored with the aid of several rotary cutting heads, then broken and finally deposited in collecting containers. The cycle time for four parts is only 1.5 seconds. For the production of short lengths (up to 120 mm), the cycle time is extended to approximately three seconds.

An internationally active medical technology company that produces and sells catheter tubes, among other things, has optimized its manufacturing process with the help of a production line from Metzner Maschinenbau. With Metzner's know-how, it was possible to replace a costly manual process with an automatic machine, saving costs. At the same time, the length accuracy and the cutting quality were significantly improved. The company supplied a fully automatic system that precisely cuts the catheter tubing to length, removes the mandrel present from the extrusion without leaving any residue and without longitudinal expansion, and then deposits the tubing in a collecting container at the end. Processing with exact length accuracy and mandrel removal The Metzner special development cuts catheter tubes to an exact length and removes the mandrel inside safely and precisely. The finished material is deposited in a collection container.

Metzner has been developing and designing production machinery for tube machining for nearly three decades. Thanks to these many years of experience, today we can offer solutions that are adapted to the variety of different tube diameters and material properties. Wherever tubes have to be cut in very large quantities, impact knife machines are used. The Metzner Dynamat series achieves up to 4000 cuts per minute with one knife and, if required, an even higher cutting performance with multiple knives. Customers have the choice between "stop & go" cut or continuous cut. There are different machine sizes for materials of up to 120 mm diameter, which are prepared as standard for a wide range of peripheral equipment and knife moistening. The Dynamat machines process elastic materials reliably and with repetitive accuracy – from silicone tubes for the medical sector to fabric-reinforced tubes and profiles. No difference whether the material comes from an extruder or is unwound from a coil.

Metzner has developed the mandrel cutting machines of the SR series for cutting off sealing rings from injection-moulded or extruded tubes with different diameters. These machines are characterised by their unique processing method and high cutting quality. First, pre-extended "rubber tubes" are clamped onto mandrels. Due to the special design of the mandrels, the mandrel can be set up and removed quickly and without special previous knowledge. The mandrels are then automatically clamped in the machine between rotating spindles and production is started. A knife carriage travels along the tubes and cuts the flat sealing rings to the desired length with either push-fit or circular knives, depending on the requirements. This cutting method is particularly impressive with its high cutting quality in combination with a high output.

The Metzner CCM 2 circular cutting machine processes steel-reinforced profiles and sponge rubber materials with dry cutting (optionally with micro-knife moistening to cool the circular knife). The standard model comes with an integrated discharge conveyor (1300 mm length); range of application both in-line and off-line.

The modular system of the MBS series is available in three sizes. The MBS 100 is the "smallest" of the three models and processes materials such as tubes and profiles of up to 90 mm wide. Depending on the material size, further machine elements such as type and number of cutting tools, length and width of the belt feed, control, feed, running direction, coating material of the conveyor belts and base frames are selected. Metzner "MBS series" cutting machines stand for outstanding flexibility when machining flexible and semi-rigid profiles made of rubber and plastic. With different cutting methods and machine components, cutting machines are created which can be individually adapted to customer requirements and are made available in the shortest possible time with hardly any development effort.

The special feature of the Metzner CCM 4: the circular cutting machine handles both wet and dry cutting. Depending on the type of cut, the CCM 4 is equipped with a water-cooling lubrication system or micro-knife moistening and preparation for suction. The standard model comes with an integrated discharge conveyor (800 mm length); application range both in-line and off-line. For tubes with suitable material properties the CCM 4 Gasket offers the possibility to cut flat gaskets with the circular knife. Suitable for tubes with max. 30 or 50 mm diameter and a tube length of 1 mm to 1000 m.

The Metzner AM 1000 is a sensation among the tabletop units. The automatic cutting and stripping machine processes cables, strands and wires up to 9 mm diameter and 6mm² cable cross-section with a special cutting and pull-off force (optional 10 mm², depending on material). The presettings are conveniently made via the modern 12" touch panel, where the operator can define all processes. Thanks to the sensors for diameter and material recognition, the AM 1000 works extremely precisely. Another special feature is the tool-free replacement of guides and rollers. This means that the AM 1000 can be changed over in just one minute. With the extensive interface preparation, the machine can be optimally expanded with peripheral devices and adapts to all customer requirements. The compact design with retractable touch-screen and the low weight of only 28 kg also offer special comfort. This makes the AM 1000 especially easy to transport.
