Contribute to the advancement of technology in the metallurgy sector.

Contributing to the search for new machining techniques, AAMS has conducted several studies demonstrating the effectiveness of the methods used:

Case study 1

Contexte :
Deep hole drilling = high pressure pumps usage – automotive sector.

Objective :
Convert to MQL drilling – energy saving.

Methods :
1- Select optimum tools on market
2- Define MQL parameter (oil variant + up to 10 bars)
3- Proof of concept
4- Tool life test

Conclusions :
MQL suitable
Energy saved
ISO tool life MQL VS Wet

Case study 2

Contexte :
Consortium project – end user, oil provider – aerospace materials.

Objective :
Evaluation of tool life using 5 wet variants.

Methods :
1- Tool life testing protocol definition
2- Oil benchmark tool life test (3 repeats)
3- Tool wear analysis

Conclusions :
Up to 30% tool life difference
Tool costs decrease

Case study 3

Contexte :
End user anticipating production growth in medical sector.

Objective :
Audit of production unit and improve productivity.

Methods :
1- One day audit of production unit and actions plan
2- Test performed on production site
3- Delivery of machinability maps using DOE technics
4- Production parameters change + follow-up

Conclusions :
Up to 40% productivity gain.

Case study 4

Contexte :
Consortium projet (Tool manufacturer, University, AAMS).

Objective :
Evaluate friction coefficient and thermal contribution of an AlTiSiN coating in order to find cutting solution for Gamma-TiAl alloys.

Methods :
