Micro5 Release Notes - Series 2
CHIRON Swiss SA, Samuel Vuadens

The Micro5 is 5 years old

At SIAMS 2016, HE-Arc presented the prototype of a miniature CNC, called Micro5, that could fit on a desk.

Two years later we introduced a first V0 series of 5 machines industrialized and in operation at the first pioneer users.

By early 2020, we were able to produce a V1 machine every two weeks in lean mode in our 200m2 workshop.

Micro5 V2

Based on user feedback from the first 25 machines, more than 50 new features and improvements are implemented for the 5 years of the first prototype.

3 main lines of action have guided our choices:

  1. Reliability: we have been working intensively on youthful defects and quality at the time of leaving our workshops.

  2. Efficiency: Feedback from the first users indicates gains in terms of machining time reduced by 20 to 40% compared to larger machines. The V2 has a spindle with twice the torque, which allows us to save even more time, about 20%.

  3. Autonomization: We respond to the demand of early adopters who now want to load automatically and achieve volume with our scalable Smartfactory project.

We are convinced that this V2 will be a great success and we hope you will enjoy our work.
