Wheel coat Ø3400

Published on 29/08/2023

Wheel coat Ø3400

Take a wheel coat Ø3400 of a Kaplan turbine by machining and all that on site?! The TACQUET INDUSTRIES teams also know how to do it!
If you want to know more, it’s here 👇

During the month of July, our teams had the privilege of working on the renovation of another hydroelectric power plant group. ♻️💧

THE MISSION: 🔍
– Resumption of the cylindrical and spherical part Ø3400 of the wheel mantle on a height of 1m.

Tolerances requested: 🔑
– Final coast of cylinder diameter and sphere Ø3400
– Surface condition: Ra 3.2 max

Machine used: Boring-Surfacer TI6500 🎯

The subtlety on this site lies in the development of a completely mechanical copier to follow and recreate the original shape of the coat. No CNC was used for this operation. 👌

Intervening on this type of site allows us to improve our techniques in order to deliver an optimal quality of service and services for our customers!

VERDICT: 🏆Successful mission🏆

This new success was achieved thanks to rigorous preparation upstream by our Design Office and the professionalism of our technicians on site. 💯

We thank Automated Precision Europe GmbH for their support on this project.

We also thank our client EDF for its confidence in this project and especially Pol Piedfer and Loic Potel for the organization of the site. 🤝

Turbine shaft machining 𝘊𝘈𝘚𝘛𝘌𝘛𝘈𝘙𝘉𝘌

Baigts Castetarbe factory, France

Turbine shaft machining

During 2023, we worked on a turbine shaft at the Baigts Castetarbe Hydroelectric Power Plant in France for our customer EDF.

  • Machining (delardage) of the shaft of 10mm at minimum radius over a length of 450mm
  • Welding of 2 half shells (machined in our workshop) on the tree by an external company
  • Machining of welded half-shells to obtain the final diameter Ø200
  • Diameter tolerance Ø200: 0.1 mm
  • Conicity: (0; + 0.1 mm)
  • Coaxiality: (0; + 0.2 mm)
  • Surface condition: Ra 1.6 (obtained: 0.3/ 0.4)

Our intervention took place in several stages:

  • Step 1: Analysis of the subject in our Design Office (feasibility, 3D modeling of the tree, implementation of our machine in the 3D work environment).
  • Step 2: Carrying out pre-work checks (Laser Tracker) by an external company to define the origins and create a reference.
  • Step 3: Installation of our machine on site and machining.
  • Step 4: Soldering half shells.
  • Step 5: Realization of controls (Laser Tracker) by an external company in order to recover the repository and adjust the machine.
  • Step 6: Installation of our machine on site and finishing machining.
  • Step 7: Completion of after-work checks (Laser Tracker) by an external company.

Machining of flanges Ø8700

Published on 07/08/2023

Flanges machining Ø8700

Can I machine Ø8700 flanges on site?
Want to know more about the last titanic project recently completed by TACQUET INDUSTRIES teams? Continue reading we will tell you everything.

In recent months we had the pleasure of working on the complete renovation of unit 1 of the EDF hydroelectric power station in Ottmarsheim for our customer Voith Hydro. ♻️💧

THE MISSION: 🔍
– Machining flange and Ø6050 H7 foundation ring
– Surfacing of the upper face of the inf ring (Ø6900 to Ø8700) then machining of the face and diameter Ø6900
– Surfacing of the inf face of the head cover (Ø6900 to Ø8700)
– Addition of modifications to the 48 Sealing Guide Pots (Drilling/Tapping, Countermeasures)

Tolerances requested: 🔑
– Horizontality and flatness of machined planes: 0.02mm/m
– Surface Condition: Ra 6.3
– Deck depth: 0.1mm
– Bores: H7

Machines used: TI8500 Boring Machine/ TU400 Boring Machine/ MAB485 Magnetic Drill 🎯

On this site, for its maximum surfacing configuration our machine TI8500 reaches 10m diameter for a mass of almost 20T 🤯

VERDICT: 🏆Successful mission🏆

This new challenge was won thanks to the preparation work carried out by our Design Office as well as the quality of work and the investment of our technicians on site. 💯

We thank Automated Precision Europe GmbH for their involvement in this project.

We also thank our client Voith Hydro for his professionalism and confidence in this project and especially Julien Lacroix, Etienne Pernot and Julia Heinisch for the organization of the site. 🤝
