About us

At ESTRA doo, based in Ljubljana, Cvetkova ulica 37, we represent, install, service various CNC metalworking machines and train operators. The company was founded in 1991. During this time, we have sold over 900 metalworking machines. The sales program includes:

  • CNC milling centers
  • CNC lathes
  • Electroerosion machines (drilling, immersion, wire)
  • Surface grinding machines
  • Shower presses
  • Machinery and materials processing equipment

We advise on machine selection, organize all transportation and set up the machine. We also perform calibration and measurement protocols on each machine, start it up and train operators. After the machine is started up, we are available for all questions, advice and service.

We service mechanics and electronics and have good relations with Heidenhain and Fanuc. Our service technicians are well trained and have a lot of experience. Service technicians are trained abroad — Heidenhain, Germany. We use the most modern equipment for setting up and servicing machines:
