Frequently Asked Questions
What is stainless steel CNC machining?
Stainless steel CNC machining is the process of manufacturing precision stainless steel parts using CNC milling, CNC turning, drilling, tapping, grinding and related machining processes.
What stainless steel grades can you machine?
We can machine common stainless steel grades such as 304, 316, 303, 17-4PH, 420 and 440C according to project requirements.
Is stainless steel difficult to CNC machine?
Yes. Stainless steel can be more difficult to machine than aluminum because it may work harden, generate heat and cause tool wear. Proper tools and cutting parameters are important.
What is the difference between 304 and 316 stainless steel?
304 stainless steel is a general-purpose stainless steel. 316 stainless steel offers better corrosion resistance, especially for marine, chemical and harsh environments.
Can you machine 17-4PH stainless steel?
Yes. We can machine 17-4PH stainless steel for high-strength and demanding mechanical components.
Can you make stainless steel prototypes?
Yes. We support stainless steel prototype machining and low-volume production.
Do you support stainless steel CNC turning?
Yes. We provide CNC turning for stainless steel shafts, pins, fittings, threaded components and cylindrical parts.
Do you support stainless steel CNC milling?
Yes. We provide CNC milling for stainless steel housings, brackets, plates, covers, fixtures and complex components.
What surface finishes are available for stainless steel parts?
Available finishes include as-machined, brushing, polishing, bead blasting, passivation, black oxide, nickel plating and laser marking.
Can stainless steel CNC parts be passivated?
Yes. Passivation is available to improve corrosion resistance and surface cleanliness for stainless steel parts.
What tolerance can you achieve for stainless steel parts?
Tolerance depends on material grade, geometry and part size. We can support tight tolerance requirements according to customer drawings.
Can you work with STEP or CAD files?
Yes. You can send STEP, IGES, X_T, SLDPRT, STL, DWG or PDF files for quotation and engineering review.
Do you provide inspection reports?
Yes. We can provide dimensional inspection reports, material certificates and first article inspection reports when required.
Do you ship stainless steel parts globally?
Yes. We support global delivery for custom stainless steel CNC machining projects.
