More demands placed on machinery The ever more complex demands in all industrial areas involve increasing demands on punched and formed components and on the machinery used for their manufacture.

For years, punching and bending machines have been required to perform much more than punching and bending operations which gave them their name. In many cases the machines must be capable of additional fully automatic operations such as coiling, insulation stripping, welding, riveting, screwing in and assembling of ready to be installed components. It is no wonder that manufacturers such as Costr.Mecc.Koradi, of Gera Lario at the Lake Como, is following the trend away from single-purpose standard machines towards custom-tailored equipment.

Koradi – following the trend away from single- purpose standard machines ▲

In addition to the BSA and BA series’, punching and bending machines, these machines are also based on the models of the Kombimat and Filomat series which are being continuously improved. The Filomat forms automatically stripped wire which is turned into spiral springs as well as other two and three-dimensional components, such as single and multi-layer magnet coils. Using a suitable PC it is also possible to produce spiral springs with variable pitch. The wire or strip can be fed from the left hand or right hand side, from the rear and from the top. The machines of the Kombimat series are modular CNC manufacturing centres with linear transfer, and are built in several sizes. The vertical working table can be equipped with presses and numerous other tolls, enabling the production of complex formed components such as hose clamps, various types of helical tension and shaped springs and coils ready to be installed. For example, these machines can handle strips up to 100mm width and wire of 14mm diameter, with a tensile strength of 400N/mm 2 . The maximum feed speed is 160m/min. Koradi, formed in 1962, pride themselves that few of their machines can be found on the second hand market. These customised machines are equipped with a numerical control that uses a special software, compatible with Siemens NC systems.

Eraser’s Model L1 bench wire stripper removes film insulations including enamel, Formvar, ML, armoured poly-thermaleze, epoxy and more from round wires 29AWG to 13AWG. A high-speed rotating insert strips insulation from the surface of the wire. Close-up stripping is possible flush to a coil body or bobbin. The Model L1 can also be used for other applications such as deflashing wires, cleaning legs of electronic components and cleaning pins on transformers and coils. The unit may also be used to clean wire wrap sockets, DIP sockets and relay sockets. The L1 can also remove oxidation, flashing, epoxy, and even contaminated solder.
