Retrofit CNC machines
from old to brand new
in 14 days.

Replace legacy Fanuc/Siemens/Mitsubishi controllers with QS F-series or Astro. Keep the mechanics, motors, and electrical cabinet — only the electronics and HMI change. Save 70–80% versus buying a new machine, with a typical ROI under 18 months.
