About us

Mira Retrofit, S.A.

Based on a long and successful history in the alpine country of Switzerland, through the company WMR Mira AG, in 2019 we began our journey in the Spanish national territory in order to concentrate and further support the most advanced technology achieved in external and internal cylindrical grinders as well as flat grinding machines.

Our offer ranges from simple repairs or partial overhauls to complete overhauls of conventional and CNC cylindrical or surface grinding machines. We also offer partial or complete Retrofit (update / adaptation to new processes) in order to improve and considerably increase the productive capacity of the grinding machine. Both a mechanical and electrical retrofit.

We also have for sale several grinding machines that we have totally or partially reconditioned.
