We’re going to describe the steps we follow at GDM to perform spindle repairs. Through these articles, we want to explain how we repair the motors we receive from our customers, always respecting the most stringent safety and quality measures. We always strive to provide the highest standards of quality and reliability in our repairs. The equipment we receive leaves our facilities in perfect condition and meets the manufacturer’s specifications.
At GDM, we are meticulous about the quality of our repairs. Here’s a video where you can see the entire process we follow; we’ll explain it in detail later.
Initial checks for spindle repair.
The first step in spindle repair is to check the winding or stator. This test is performed to determine if there are any short circuits or shorts. If this is the problem, the winding would be replaced. This solution would be provided regardless of whether the winding was encapsulated or not.
The next step would be to check the proper functioning of the encoder. Also in this step, the tool clamping sensors would be checked.
Subsequently, the shaft taper would be checked for any jumps, i.e., tool deviations. The collet clamping force would also be checked to ensure it is adequate for the tool.
Engine disassembly.
After performing all the initial checks and making any necessary corrections, we move on to the disassembly phase.
This would allow us to verify the need to replace the O-rings that ensure watertightness. In addition, all the engine’s reworked parts would be inspected.

Another important component is the bearings, since they will operate at very high rpm. It’s also important to keep in mind that they will have to withstand high loads. The bearing is a sensitive component because it occupies a key mounting position. We mustn’t forget that they must also be subjected to a very specific torque, known as preload. Bearing assembly is crucial, since a failure in its assembly will prevent the engine from functioning properly.
Final Tests.
Once all the checks and repairs have been completed, we proceed with the final tests. For this purpose, we have test benches for most brands and types of engines on the market.
On the test benches, we subject the engines to operational tests. We perform these tests in both vertical and horizontal positions, depending on the engine’s operating design.
The engine’s run-in on the test bench consists of running it at certain rpm for specific test times. This provides data on vibrations, operating temperature, engine consumption, and other key variables. This ensures the engine is in perfect working order.
After completing the run-in tests, the cone clamping force is checked again. The objective is to ensure there are no jumps or vibrations from the tool on the shaft.
Finally, the engine is thoroughly cleaned and repainted. After all these processes, the engine returns to its original condition and meets all manufacturer specifications.
There’s only one last step left: packaging the engine. For transport to the origin, the engine is properly prepared in a box that guarantees absolute safety. Perfectly padded wooden crates prevent any type of accident involving such sensitive and expensive equipment.
As you’ve seen, at GDM we are scrupulous about the quality of our repairs. And if you need any clarification or more information about our repair processes, you can write to us RIGHT HERE.
