Mecartex SA

Mecartex SA is a Swiss company founded in the early 2002 and specialized in designing and producing systems for high precision applications based on flexures where small movements in a range of millimetres with accuracy up to nanometres are required.

MECARTEX activities started ten years ago within the Laboratoire de Systèmes Robotiques (LSRO) at the Swiss Federal Institute of Technology of Lausanne (EPFL).

The success of the company is based on the excellent mix of theoretical know-how on micro mechanics and flexures acquired at EPF of Lausanne in the late 90’s where two of the three co-founders, Stefano Bottinelli and Yann Mabillard, were working. They have made several years of practical experience on designing flexure based motion system and on the capacity to manufacture and assembly all components necessary to build the final solution. The core know-how of the company is based on the capability of mastering two technologies: design of high precision products based on flexures and manufacture with EDM of high-precision mechanical elements. The company is very proud to present itself as a good example of “invented and made in Switzerland”.

 

Relevant experience 

MECARTEX has a solid experience in design and manufacturing high precision mechanisms based on flexures applied in several fields:

  • Metrology: development of the 3D Nanotouch Probe for the Swiss National Institute of Metrology (METAS).
  • Astronomy: development of the Differential Delay Lines (DDLs) within the ESPRIT project of European Southern Observatory (ESO). The DDLs consist in a high precision translation stage with a stroke of 70mmwhich operates in vacuum.
  • Micro-manufacturing
    • High dynamic micropositioning device for micro electrodischarge machining (EDM). Based on the Delta parallel kinematics and exclusively flexible bearings, the new device shows structural frequencies higher than 400Hz with a 1Kg load. The micro robot is equipped with moving magnet actuators, optical encoder with resolution of 10nm.
    • Self-levelling device for nanoimprinting The nanoimprinting machines are also equipped with an active pre-levelling with accuracy of 20µradiant, which often is not fine enough. For this reason a called “self-levelling” device was developed.
  • Space: collaboration in developing the Point Ahead Angle Mechanism (PAAM) for ESA’s Laser Interferometer Space Antenna (LISA).
