At GDM, servo recovery goes far beyond simple repair. Our aim is not just to get the equipment working, but to get it working as it did on day one. That is why when a motor arrives at our facilities, a total transformation process begins.

It’s not just about replacing faulty parts. We carry out a complete disassembly, evaluate each component and work to restore the equipment to its original functionality and aesthetics. And we back it up with facts: before leaving GDM, all servo systems are put through a test bench that guarantees the performance of the repair.


Case study: a Siemens 1PH7137-2ND22-0BA0 spindle.

A clear example of our remanufacturing process is this Siemens spindle model 1PH7137-2ND22-0BA0. It arrived in our workshop covered in grease, with multiple failures and severe wear.

As you can see from the pictures, the level of deterioration and contamination with grease and debris was more than noticeable.

There was a lot of dirt and damage inside the unit.

We replaced the bearings, the encoder, the seals and the control connector. We also repaired a shunt winding, solved a phase short circuit and repaired the shaft due to its high level of wear.

But that was not all. We completely removed the accumulated dirt and left the engine looking and running like new.

The final result speaks for itself and you can see it in the pictures that accompany this article.

You can see how the equipment entered and left our workshops after the repair. The final appearance is impeccable, as if it were a brand new piece of equipment, and after passing through the controlcheck department, the ‘as’ is not necessary. This is tested and guaranteed equipment in perfect working order.

In this video you can see the before and after in detail. The video is in Spanish.
