IMPELLERS
SWSTech has a team of experts in the field of impeller and blisk manufacturing. SWSTech is a manufacturer of a large variety of impellers. Apart from the machinery on the premises we offer a wide selection of services and expertise in the field of consulting and nc-programming:
Open Impeller
Machining with flank-contact for ruled surfaces or point-milling for arbitary surfaces.
Time calculations and process optimization.
Closed Impeller
Milled out of one block for maximal strength.
No matter what material – we have a wide range of tool and strategy-knowledge to get the most economic process.
Blisks / Blings
Bladed disks (Blisks) and blades rings (Blings) as well as single blade machining.
Prototypes / Series
No matter on the batch size – we will realize your prototype series.
Manufacturing of open impellers and blisks (bladed discs)
- Flank milling of the blades (ruled surfaces)
- Point milling of arbitrary surface blades
- Access from the shroud or from inlet and outlet (side-entry-milling)
Manufacturing of shrouded impellers or blings (bladed rings):
- Open milling and brazing
- Open milling and welding
- Integral milling by side entry access
Size range:
- 5mm < Diameter <= 1000mm, larger diameters on request.
We develop the milling processes e.g. for the following materials
- aluminum alloys
- steel
- stainless steel
- titanium
- nickel-/cobalt- based alloys
Based on the extended knowledge of tools and strategies we can carry out various optimizations
- Cycle time optimization
- Maximum process stability
- Tool cost reduction
Furhtermore, we are using effective strategies
- Tool and material dependent HSC-strategies
- Plunging
- Trochoidal milling
- Optimization of material removal
- Special cutters
To be able to program with the best strategy, customer data are adapted to the process requirements if necessary.
We use ConceptsNREC MAX-PAC impeller milling software and CGTech Vericut® for simulation and optimization.
The SWSTech postprocessor translates the NC-data into machine-specific G-code.
