The MM85 rod breakdown wire drawing machine  was developed by Niehoff to simultaneously draw two copper , aluminium or alloy wires to finished diameters of 1mm-5mm at production speeds up to 38m/second. It includes a quick-change drawing die system, a fully-immersed drawing basin with reliable separation of drawing emulsion and gear oil via a mechanical seal, and a touch screen-based user interface and fault display.

MM85 rod breakdownwire drawing machine can be combined with the two-wire version of an R501 or an RA501 continuous resistanceannealer . The R501 annealer was designed for copper wire, while the RA 501 annealer is adapted to the requirements of aluminum and aluminium alloy wires. Both annealers are designed for energy efficient operation.

Wires exiting the annealer are completely dry. The entire wire path inside the RA501 aluminium annealer is covered with protective gas to prevent oxidation of the wire surface. A digital annealing  voltage controller ensures repeatable and consistent wire annealing quality. Freely programmable control systems(PLCs) and standardised interfaces make the drawing and annealing line easy to combine with many spooling and coiling systems. Niehoff has developed  take-up and spooling systems for the whole range of wire drawing machines

As a result of the design and control characteristics, the wires drawn on an MM 85wire drawing machine have similar properties with very fine tolerances along their entire length and operating conditions are characterised by considerably reduced down times. Based on 7,000 hours per year of operation and 80% utilisation, wire production output of up to 3100 t/a for copper wrie and 18000 t/a for aluminium wire, are possible.
