Housing for pumps and compressors always have similar properties: large sizes, grey cast-iron material and very tight tolerances, specially between the holes.
Our demonstrator was as follows:
Material: FC250
Required coaxility 10 microns
Size >700 mm
Bore size 350 mm
Finishing the 350 mm bore
In this case the machine used was an a81nx and here we are going to focus on the finishing phases. The bore was finished with:
350 mm boring head
40 mm lathe bar using the hale function to position the cutting edge towards the part for finishing the flange
Outcome
The final result of the machining of this part, considering roughing, and finishing
