Niehoff: This is How Sustainability Works

Overhaul completed on Niehoff MMH 101 multiwire drawing machine, built in 2000.

Whoever decides in favour of a Niehoff machine not only gets the latest technology, efficiency in all areas, and the best service, but also ensures the longevity and stable value of their machine. When it has been in production for years and has many operating hours behind it, an overhaul by Niehoff specialists is a worthwhile and sensible measure. In short, they bring the machine into as-new condition. This is what Niehoff understands by true sustainability. As an interesting extra, this can also increase the productivity of the machine.

After Niehoff specialists have modernised the machine – on which Niehoff gives a warranty of 12 months – its process reliability is even higher.

Typical Case

The Niehoff modernisation team is constantly in action. One of the typical projects is a multiwire drawing machine type MMH 101, year of construction 2000, which came to Schwabach for its rejuvenation after 90,000 hours of use.

Good Reasons for an Overhaul

After 40,000 hours in operation, the bearings of a machine have reached the end of their service life. If it continues to be operated, the risk of unexpected machine downtime increases. This is where overhaul comes in. It also prevents possible bearing damage, which in turn can cause very costly consequential damage, such as damage to the gearboxes and bearing seats or the destruction of shafts and gears.
Niehoff also considers an important argument in favour of a timely overhaul to be that, after special modernisation measures by the Niehoff team, customers get the affected machines back in such a way that their productivity can be increased by up to 30%. Of course, Niehoff knows that the time factor plays a major role in production. As a rule, the professional overhaul of a Niehoff machine at the Niehoff premises takes only three weeks from the time the machine is switched off at the customer’s premises until it is put back into operation there.

Measures in the Case of the MMH 101

In Niehoff’s MMH 101 project, the measures included a general overhaul of the mechanical part of the machine and new wiring. Overhauling the electrical part is particularly advisable when there are no longer any spare parts for control and drive components.
The machine was dismantled at its location, taken to the Niehoff headquarters in Schwabach (pictures 1 to 4), and disassembled there (pictures 5 to 7). Afterwards, the components were cleaned and all bearings were replaced with new ones. In addition, the team installed new sealing flanges with labyrinth seals. Technically brought up to date, the machine (pictures 8 to 10) underwent a final inspection before it was transported back to the customer. Installation and recommissioning completed the successful overhaul of the Niehoff machine.

Know-how and OEM Parts

Niehoff is convinced that Niehoff specialists are best able to overhaul Niehoff machines because:
■ they know all the special features and even the smallest machine details,
■ they have all the important and necessary data at their disposal,
■ they are masters of their trade with a lot of experience.

A key factor that makes overhauls by the Niehoff team of experts so successful is the fact that Niehoff manufactures the spare parts needed for any overhaul in-house and in OEM quality.
Niehoff relies entirely on itself for that. This also applies to bought-in parts, because Niehoff guarantees that they meet the high Niehoff quality standards.
