Why CNC Machining
What Makes CNC Machining
the Right Choice?
Unmatched Dimensional Accuracy
CNC machining delivers tolerances as tight as ±0.001mm — critical for aerospace actuators, medical implants, and precision instrumentation where functional failure is not an option. Our 5-axis simultaneous machining eliminates setup-to-setup error accumulation.
±0.001mm5-axisCpk ≥1.67Broad Material Compatibility
From titanium alloys and Inconel superalloys to PEEK medical plastics — CNC machining works across the full spectrum of engineering-grade materials. Each material is supported with full mill certification traceability and dedicated tooling parameters.
Ti-6Al-4VInconel 718PEEKSS 316LScalable from Prototype to Volume
CNC machining is uniquely scalable — the same setup parameters that produce a 1-piece prototype generate production-quality volume parts without re-engineering. This makes it the preferred process for DFM-validated production ramp-ups.
Prototype · 1 pcVolume · 100K+Regulatory Compliance Ready
AS9100D, ISO 9001, and ITAR registration make MW+ CNC machining a qualified supplier for aerospace OEMs, defense primes, and FDA-regulated medical device manufacturers. Full FAI, CMM reports, and material certs on request.

Get a Free QuoteWhat is CNC machining and how does it work?
CNC (Computer Numerical Control) machining is a subtractive manufacturing process where pre-programmed software controls machine tools to remove material from a workpiece with extraordinary precision. At MW+, our 5-axis CNC centers interpret G-code instructions to guide cutting tools along X, Y, Z, A, and B axes simultaneously — achieving tolerances as tight as ±0.001mm on metals, plastics, and exotic alloys.
What tolerances can you achieve?
Our standard CNC machining tolerance is ±0.01mm. For precision applications we routinely hold ±0.005mm, and with specialized 5-axis setups and ultra-precision tooling, we achieve ±0.001mm. Surface roughness ranges from Ra 3.2μm (standard as-machined) to Ra 0.4μm (fine finish) and Ra 0.1μm (mirror polish). All tolerances are verified with Zeiss CMM equipment and documented in inspection reports.
What materials can you CNC machine?
MW+ machines 50+ engineering-grade materials including: aluminum alloys (6061, 7075, 2024), titanium (Grade 2 and 5), stainless steel (303, 304, 316L, 17-4 PH), tool steels, Inconel 625/718, Hastelloy, Waspaloy, medical-grade plastics (PEEK, Ultem, PTFE), and many more. Each material is sourced with full mill certification for complete traceability.
How long does CNC machining take?
Our standard lead time is 5 business days for prototypes and small batches. Volume production typically runs 10–15 days. We offer 48-hour express CNC machining for urgent projects. Lead times are confirmed at quoting and backed by 24/7 production capacity with robotic automation. Quote response time is guaranteed within 24 hours of receiving your CAD files.
Do you provide quality certifications and inspection reports?
Yes. MW+ is ISO 9001:2015 and AS9100D certified. We provide Certificate of Conformance (COC) with every shipment, CMM inspection reports on request, material certifications (mill certs) for full traceability, First Article Inspection (FAI) reports per AS9102, and SPC data for production runs. ITAR-registered for defense and government contracts.
Can you ship CNC machined parts worldwide?
Yes. Our Shenzhen factory ships CNC machined parts to 42 countries worldwide — including the USA, EU, UK, Japan, Australia, Canada, Singapore, and Middle East. We offer DDP (Delivered Duty Paid), DAP, and EXW trade terms. Export documentation, customs paperwork, and ITAR-compliant shipping for defense components are all handled in-house.
