Spindles and seats made of the following materials can be reconditioned:

 

 

  • AISI307 (St.St) in combination with stelite
  • Nimonic 80A

 

First the spindles and seats are analysed to know what kind of base materials are used. This will determine the welding procedure.

 

All burned and worn layers are machined off and rewelded on automatic welding machines. Final machining takes place on horizontal CNC controlled turning tables to meet the original tolerances specified by the engine builders.

 

After machining a full measurement report is made, also the seating are/bottom side fillet to stem is dye checked.
