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 .
