FAQs: Difficult-Alloy CNC Milling
How do you control distortion in thin-wall Inconel or titanium parts?
We use dedicated fixture strategies, controlled step-downs, optimized toolpaths, heat management and in-process inspection to maintain geometry.
Can you meet tight positional or flatness controls on PH stainless parts?
Yes. We define datum structures early, plan stable clamping, and apply precision milling and grinding, with CMM verification down to position 0.010 mm and flatness 0.005 mm.
What surface finishes can you achieve?
Precision machined finishes to Ra 0.8 μm are typical; grinding can achieve Ra 0.2 μm. EDM surfaces down to Ra 0.8 μm, with options for post-processing.
What is your minimum thread size?
M1.0 for milling; smaller threads may be feasible on turned or Swiss features (down to M0.8 in Swiss turning).
Do you provide full traceability and FAI?
Yes. Material and lot traceability, FAI, ballooned drawings, full dimensional and special-process records are available upon request.
