Investment casting machining

Investment castings after casting process could only reach freedom tolerances itself.For more accurate tolerances,we have to meet by rough machining,some even require secondary machining.To serve our customers better,we have developped a machining line to machine parts we could not reach by investment casting.

Machining advantages of investment castings from Fly foundry:

*Wide range of machining materials.We could machine various investment castings,either steel,iron,aluminum is workable.
*Advanced machining equipements are equiped,such as cnc,milling machine,boring machine,drilling machine,ect.
*Total production time is saved.We would machine parts directly after casting process.So the lead time is ensured.
*Low machining costs are quoted.Machining service provided is just for better service.
*Further surface finishing process could be offered also after machining investment castings,like painting,powder casting,ect.
*Mature machining technology.Our machining workshop is separated from casting workshop,each workshop is equiped with specialized engineer team to make sure each process is clear .
