Walter Tools

With energy towards more cost efficiency

Wicket gates

Wicket gates in water turbines are a non-rotating yet adjustable radial grill of blades which controls the inflowing volume of water and can also cause it to swirl. The wider the opening, the faster the water flows and the higher the energy yield. The guide grill contributes towards keeping the speed, and therefore the output, of a turbine constant.

We have just the right metal cutting tools and processes for machining the blades of the guide grill and guaranteeing cost-efficient machining.

Here is a selection of our tools:

  • Walter Valenite heavy-duty cutter for roughing the flange and the profiles
  • Walter Valenite helical cutter for roughing the flange external diameter
  • Walter Valenite ball nose mill for pre-machining the profile transitions
  • Walter Valenite round insert cutter for finishing the profiles
  • Walter Valenite indexable insert drills and boring tools for machining the flange holes
  • Walter Valenite round insert cutter and octagon mill as roughing tools for the circular interpolation milling of the flange center hole
