Document audit

We check the order conformity and the different documents of the machine. Manuals are also controlled to be sure there is enough and accurate information in it.

Mechanical check

On every machine, we make sure of the proper assembly and function of all mechanical component. The guideways, ball screws, scrappers, lubrication… as well as the dynamic behavior of every axis is checked, and the tool changer stress tested. If it moves, we test it.

Machine geometry

The geometry is checked as per ISO standards. Every point of the norms is measured and compared to the maker report. Upon customer request, we may also execute a cutting test.

Electrical assembly

The electrical assembly of the machine is checked by following our strict checklist. We also ensure the accuracy of the electrical drawing to facilitate future maintenance.
