China CNC Machining Factory for One-Stop Services

Date:2026-07-09Article editor:Starting Point PrecisionViews:111

In precision engineering, executing complementary processes—turning, milling, grinding, and EDM—under one quality system distinguishes true manufacturing partners from job shops. This integration eliminates supplier interface risks, reduces cumulative tolerances, and enables closed-loop process feedback.

Our Core Equipment List 

The following table represents our actual machinery as documented in our precision equipment list. It includes multi-axis machining centers, turning centers, EDM, and grinding machines from world-leading brands.

We combine this hardware with in-process probing and Zeiss CMM inspection to maintain < 5µm total runout on critical features, validated per ISO 2768-mK and ASTM B221 for aluminum alloys.


Process Integration in Action

True one-stop service is about intelligent routing. For a recent aerospace component (7075-T6 aluminum housing), we executed:

    1. Turning – on DMG CTX beta 800 and Mazak NEX-108 for rough OD/ID.

    2. 5-Axis Milling – on DMG HSC 75 linear for complex contours and angled flanges, achieving 0.02mm true position.

    3. Grinding – on MICCO surface grinders and GU32-60NC cylindrical grinders for finishing mating faces to Ra 0.4 µm.

    4. EDM – using Sodick ALN400Gs wire EDM for internal splines and MAKINO EDGE3 sinker EDM for blind cavities (L/D 8:1).

This reduced setups by 60% and cycle time by 28% on a 5,000-piece order.

Why Vertical Integration Matters

Internalizing all processes—from turning and milling to grinding and EDM—eliminates logistics gaps and enables adaptive machining. For example, if milling induces thermal stress, our grinding station compensates in the same fixture—impossible with separate vendors. This approach cut scrap from 4.2% to 0.7% for a medical device client (316L trocars). We also use digital twin simulation (Siemens NX), reducing prove-out time by 40%.


Real-World Case: Automotive Turbocharger Housing

A German OEM required an Inconel 718 housing with:

    ●  Turned OD ±0.015mm (on DMG CTX beta 800)

    ●  Milled cooling fins (0.8mm wall) (on DMG HSC 75 linear)

    ●  Ground sealing surfaces (Ra 0.2 µm) (on GU32-60NC grinder)

    ●  EDM-drilled film-cooling holes (Ø0.5mm, 20° angle) (on Sodick ALN400Gs)

We delivered first articles in 6 weeks with 100% compliance. The client noted: “This is the first Asian supplier that truly integrates all needed disciplines.”

Quality & Continuous Improvement

All machines are MES-connected for tool wear, vibration, and temperature monitoring. We apply SPC on critical dimensions; our CMM lab is climate-controlled (20±0.5°C) per VDI/VDE 2634. Our 12-month non-conformance rate is 0.23%. We also practice green manufacturing—coolant recycling and on-site EDM oil regeneration reduce waste by 75%.


For aerospace, medical, and automotive applications, achieving ±2 to ±5 micron control amid thermal and tooling dynamics requires not isolated machine capability, but a harmonized process chain. Our facility is certified to ISO 9001:2025, AS9100D, and ISO 13485, and employs digital simulation, SPC, and a climate-controlled metrology lab to ensure form, fit, and function from prototype to production.

Frequently Asked Questions

Q1: Where can I find the full list of your machining equipment?
A: Our complete and verified equipment inventory is publicly available at https://www.startprecision.com/edw.html, including models, brands, and quantities.

Q2: What is the maximum part size for your 5-axis DMG HSC 75 linear?
A: The HSC 75 linear handles workpieces up to 750 × 600 × 450 mm. For larger parts, we use our HAAS EC400 horizontal mills. See all specs on our equipment page.

Q3: Do you provide material certificates and full traceability?
A: Yes. Every batch includes EN 10204 Type 3.1 mill certs, incoming inspection reports, and in-process CMM logs—all on your customer portal.

Q4: Can you combine EDM and conventional machining in the same fixture?
A: Absolutely. We design custom workholding for transition without re-clamping, ensuring datum consistency across our MAKINO and Sodick EDM machines.

Q5: What is the typical lead time for a prototype?
A: For simple geometries (turning + milling), 5–7 working days. For complex parts (grinding + EDM), 10–14 days. Expedited service available.

Q6: Are your processes compliant with aerospace or medical standards?
A: We hold AS9100D (aerospace) and ISO 13485 (medical) in addition to ISO 9001:2025. Our EDM and grinding areas are Class 8 cleanroom compatible.
