LFV technology is a registered trademark of Citizen Watch Co.,Japan.

Always able to give our best !

LFV® technology ( « Low Frequency Vibration ») is machining technology by low frequency oscillations that has been developed and patented by the machine constructor Citizen.

This oscillation is generated on the axis in cutting direction and allows splitting of chips into smallest fragments.

This avoids problems with chips due to materials that generate long chips, without deteriorating part surfaces nor dimensions.


We are aware of the growing importance of quality assurance and deadlines.

Therefore we invested in this technology – securing our production and continuously improving our customer service rate.

First time in France


The latest  Citizen M532-8 machine is a revolution in productivity.

It is equipped with 2 B axes as well as the new LFV® technology.

A truly technological advance, enabling us to offer even better production services in highly complex projects.

3D control 


We are now equipped with the latest 3D machine and are thus able to guarantee best measurements and traceability to our customers !


All production equipment is directly linked to our 3D measurement machine per USITRONIC© process.

Dimensional corrections are now automatically handled by this entity and guarantee radical reliability and security of our production without any human intervention.

This technology was developed by the CETIM and enables SUNAP to continue its involvement in « The connected plant of the future ».

Machine de controle Keyence
Optical control 


While searching for a productive, fast and intuitive control mean, we decided to invest in the IM Keyence dimensional measurement machine !

It has recently been installed in our metrology department and enables us to gain time by carrying out :

  • Fast and complete production follow up controls

  • SPC recording, and in a near future storage of data for customer records.

4.0 plant

We do our best being a state-of-the-art industrial producer as well as a CSR responsible employer, in order to preserve our environment and guarantee our employees’ wellness.

Our philosophy  : Offer the Best !

SUNAP lately moved to a newly constructed 1500 m² production plant.

This entirely connected plant will continuously improve our service rate and thus customers’ satisfaction rate.
