CNC turning services: This process transforms raw metal into finished products. Using numerical control, machine tools guide a cutting tool to produce the desired shape. Roughing and finishing are the two main types of CNC turning services, each serving a unique purpose in shaping the material.

Finding CNC machining services in China: Locating a reputable CNC machine shop in China is straightforward. Identify your requirements, understand the difference between one-sided and two-sided CNC machine shops, and consider shipping logistics. Look for shops that offer small lot production and have strong engineering capabilities, especially in CAM (Computer-Aided Manufacturing).

Using a CNC machine shop in China: To meet your manufacturing needs in China, start by finding a shop that can produce your required quantity and work with your material type. Negotiate the production process and pricing, ensure the shop is legally registered in China, set up a shipping agreement, and finalize a factory agreement for production. Research your options and consider your timeline to make an informed decision that aligns with your manufacturing goals and deadlines.

Using a CNC machine shop in China effectively involves several key steps:

Determine production capacity: Assess the CNC machine shop's capability to produce the desired number of pieces daily. If your project requires a high volume, such as over 10,000 pieces per day, you may need to consider additional factors like leasing an induction machine.
Material compatibility: Choose a CNC machine that is suitable for the type of material you plan to use. This will ensure that the manufacturing process is optimized for your specific material, leading to better quality products.
Negotiate pricing: Research and compare prices among various CNC machine shops to find a competitive rate. It's important to balance cost with quality and ensure that the price aligns with your budget and project requirements.
Legal and regulatory compliance: Verify that the CNC machine shop is legally registered in China. This ensures legitimacy and reduces risks related to compliance and legal issues.
Shipping and logistics: Establish a clear shipping agreement. If you're not comfortable with handling shipping from China, explore your freight options to ensure a smooth delivery process.
Factory agreement and production: Once you've selected a CNC machine shop, set up a factory agreement outlining the specifics of your project. This agreement should detail the production requirements, quality standards, timelines, and delivery schedules.
Research and customization: If your project requires custom solutions, take the time to research and find a CNC machine shop that can cater to your specific needs. Whether it's a one-sided or two-sided CNC machine shop, the key is to find a service that can produce parts to your exact specifications.
Project timeline: Consider your timeline and urgency. If you need quick production, focus on finding a CNC machine shop that can meet tight deadlines. However, if you have more flexibility, you might negotiate better pricing and quality options.
Production process negotiation: Work closely with the CNC machine shop to negotiate the production process. This includes discussing how the material will be cut, the specific CNC machines used, and any unique manufacturing processes required for your project.
Finalizing the deal: Once you're satisfied with the CNC machine shop's capabilities, pricing, and the proposed production process, finalize the deal. Ensure that all agreements are clearly documented and understood by both parties.

By following these steps, you can effectively use a CNC machine shop in China to meet your manufacturing needs. The key is thorough research, clear communication, and a detailed understanding of your project requirements to ensure a successful manufacturing partnership.

PartzPro Frequently Asked Questions

The "Open-Book" Business Model

Q: Why is there a factory invoice in the box?

That is your Commercial Import Invoice. Because we ship Factory Direct to your door, international customs requires an invoice that travels with the package.

Transparency & Compliance: This invoice lists the origin factory (showing you exactly who made your parts) and declares the exact value you paid at checkout.
Why it matches your payment: We ensure the commercial invoice matches your transaction value so that Customs calculates your duties correctly and legally, preventing delays or penalties at the border.

Q: Why don't you offer Instant Quotes?

Because "Instant" could be "Inaccurate." Some use algorithms to:

The "Bait & Switch": They sometimes quote low instantly, then email you 24 hours later to raise the price once a human actually looks at it.
The "Risk Buffer": They may inflate the price just to cover the errors their algorithm makes.

We measure twice, cut once. We have the factory validate the CAM strategy before we give you a price. You wait a few hours, but the price you get is the price you pay—guaranteed. No surprises.

Q: If I have the factory’s info, why shouldn't I just go direct next time?

First, strictly speaking, you cannot. To protect our platform, our Terms of Use include a Non-Circumvention clause that prohibits direct transactions with our suppliers for 24 months.

But practically, clients stay for the "US Shield." When you order through PartzPro, your money is held in US-based Escrow. We handle the legal leverage, language barriers, and financial security. If you go direct, you lose that protection and have zero recourse if something goes wrong.

Q: What exactly does your Service Fee cover?

Your fee covers Financial Security (Escrow), Vendor Vetting, AI Engineering Analysis, and Project Management. We act as your US-based legal firewall. We find the best factories, negotiate the rates, and hold the money until the job is done right.

Logistics, Customs & AI Technology

Q: Who handles the HTS Codes and Customs paperwork?

Our AI does the heavy lifting; you just confirm the release. We don't leave you guessing on complex government tariffs.

Heavy AI Analysis: Our proprietary AI Assistant performs a 40-point analysis of your part's geometry and material. It automatically searches the official US Government HTS database to generate a precise HTS Code Breakdown for your specific parts.
The Process: This data is provided to the carrier (DHL/FedEx/UPS). When the broker contacts you, the classification is already estimated—you simply confirm it to release the shipment.

Q: Who pays the duties?

You do—which saves you money. Because we ship DAP (Delivered at Place), you pay the exact duties owed to the government based on the AI-generated HTS code.

Why this is better: Competitors who offer "Free Shipping/DDP" often inflate the price to cover the worst-case tariff scenario. By paying the actual duties yourself, you ensure you are never overcharged for import taxes.

Q: How fast is shipping?

Since we skip the "Middleman Warehouse," our standard international shipping is extremely fast (typically 3–5 days transit). Your parts fly directly from the machine shop to your desk.

Quality Assurance & Liability

Q: Competitors inspect parts at a US warehouse before shipping. Why don't you?

Because "double handling" kills speed and adds unnecessary cost. We operate on a "Dock-to-Stock" model. The factory performs the rigorous QC, and parts ship directly to you.

We treat you like a professional: we know you will verify the fit and function of your parts upon arrival. By removing the redundant middleman inspection, we save you on cost and 3–5 days on lead time.

Q: What happens if the parts arrive out of spec?

You are protected by the PartzPro Escrow Guarantee. Because we hold the funds, the factory does not get paid until you verify the order.

The Process: You have a 3-Day Inspection Window upon delivery to verify fit and function. If parts are non-conforming, simply upload a photo and inspection report within that window. We will either force an immediate priority remake at the factory’s expense or issue a refund.

*Bulk Order Extension: For large volume orders, this inspection window can be extended. To request an extension, simply reply to your automatic invoice email.

Q: Does your AI just check for geometry errors?

No. Our AI Cost-Driver Audit goes beyond simple DFM (Design for Manufacturing). It helps you perform Value Engineering by highlighting features that are disproportionately expensive (e.g., deep pockets, tight radii, non-standard threads). We show you the cost drivers so you can engineer the price down before you order.

Payments & Corporate Orders

Q: We are a company, not a hobbyist. Can we pay via Purchase Order (PO)?

Yes. We specialize in serving agile engineering departments and mid-sized manufacturing firms.

How to order with a PO: You can select "Pay via PO / Wire" at checkout or email our sales team directly with your PO attached. We will verify your company details and send a payment link or wire instructions immediately so production isn't delayed.

Q: Do you offer Net-30 Terms?

We offer terms to qualified business partners after an initial credit review. Please contact our sales team to set up your corporate account. For new customers, we recommend using our PO-to-Wire workflow for the fastest start.
