Right-hand cutting reamer with expanding blades. Due to the unique Hunger relief grinding operation the blades have a progressively increasing clearance angle giving a soft cutting action. Starting with size D 12 the adjusting nut is marked with an annular scale. One graduation of the scale corresponds to a change of the reamer diameter by 0,01 mm. The reamers are available with standard blades made of high quality special steel to ensure superior cutting performance. The reamers are also available with hard chromium coated blades. The hard chromium coating has superior hardness in combination with a low friction coefficient. Thus reamers of the "hard chromium" series are particularly suitable for reaming abrasive materials and materials with a tendency to adhere to and to build-up the cutting edge.

Application The reamer for reaming longer holes and adjacent holes to be reamed in line with each other. Description Right-hand cutting reamer with extra-long expanding blades. The blades are approximately 2/3 longer than the blades of reamer type D. Due to the unique Hunger relief grinding operation the blades have a progressively increasing clearance angle giving a soft cutting action. The reamers are available with standard blades made of high quality special steel to ensure superior cutting performance. The reamers are also available with hard chromium coated blades. The hard chromium coating has superior hardness in combination with a low friction coefficient. Thus reamers of the "hard chromium" series are particularly suitable for reaming abrasive materials and materials with a tendency to adhere to and to build-up the cutting edge.

Right hand cutting solid reamers with extra long shanks. The front end of these reamers is ground to act as pilot. The cutting edges are precision ground with a gradually increasing relief angle to eliminate chattering and to permit easy and smooth chip formation. The reamers are provided with a hard chromium coating. The very hard chromium coating reduces friction, giving improved chip flow and reducing the tendency for built-up edges.

Right-hand cutting reamers with adjustable blades and with extra long cylindrical shank with square. Cutting edges with the unique Hunger special grinding (progressively increasing clearance angle) ensure a soft and smooth cut. A guide bush, which can be supplied in addition to each reamer size and which is pressed against the valve seat during reaming, facilitates handling and enables optimum accuracy. (see leaflet) The blades of the reamer are made of special steel, which is characterized by particularly good edge retention. In the "hard chrome" version, the blades are also hard chrome-plated. The hard chrome layer is characterized by high hardness and low coefficient of friction. Reamers of the "hard chrome" version are therefore particularly suitable for reaming materials with a high wear effect and materials that tend to stick and form built-up edges.

Right-hand cutting shell reamer with expanding blades. Due to the unique Hunger relief grinding operation the blades have a progressively increasing clearance angle giving a soft cutting action. The reamer fits on a tool bar and may be positioned along the tool bar at any desired position. The reamer is automatically locked in place on the tool bar by an expanding spring coupling as soon as the reamer blades are brought into engagement with the bore. Expanding tool bar guides and supporting fixtures for the tool bar are available to ensure excact alignment of the tool bar when reaming a series of aligned holes. The adjusting nut is marked with annular scale. One graduation of the scale corresponds to a change of the reamer diameter by 0,02 mm. The reamers are available with standard blades made of high quality special steel to ensure superior cutting performance. The reamers are also available with hard chromium coated blades.

The function of gaskets is to prevent the leakage of medium outside the equipment. Static seals are used in many applications such as plumbing and heating systems, sealing fasteners, containers and pipeline construction. They are washers, rings or frames which generally are adapted to the whole width of the sealing surface. They can be used for example in flange connections of pipelines, pumps, motors, valves, etc. The gaskets are made of various materials such as: Rubbers, fiber plates, synthetic plates, graphite, PTFE, etc.

The systems of the FTS familiy offer thickness measurements with extreme stability and accuracy. Applying them in extrusion lines provides reliable measurement results in high precision and thus creates the basis for controlling the production process and eventually the quality achieved.

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.

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.

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.

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.

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 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.
