IMPELLER/BLISKS
PRÄWEST is milling, turning and grinding the following materials Aluminum,
Titanium, IMI 834, Inconel/Waspalloy, Nimonic - Udimet, 17 - 4 PH and
other stainless and heat resistant alloys.
We have extensive experience in machining complex parts, such as:
- Blisks for turbines
- Compressor impellers and turbines (shrouded and conventional)
- Impeller wheels for turbines
Size is only limited by the weight of the raw material (Max: 11 Tonnes) and a
maximun diameter of 2500 mm.
