  Which work fits your machine and which to skip

The fastest way to get work for my cnc machine is to stop bidding on everything. Look at the last 30 jobs that ran without scrap. Sort them by material family, part size and tolerance band. One or two groups will stand out. That group is your niche, and it came from your own spindle hours, not from a market report.

A narrow niche changes how you quote. If nine of your last ten jobs were 6061 aluminum brackets between 100 mm and 400 mm long with a ±0.05 mm tolerance, you already know the cycle time, the fixture and the deburring step. You can answer an RFQ the same morning. A generalist shop bids on the same part blind and takes three days to reply.

Pick a niche with a real buyer pool. In Dongguan and across the Pearl River Delta, the steady demand sits in automotive and EV fixtures, medical device housings, robotics and automation frames, and industrial machinery parts. If your machines are 3-axis mills with 500 × 500 × 450 mm travel, medical and automation work fits. If you run a 4,000 mm bed, sheet-metal frames and long structural rails fit better.

Do not narrow to a single customer. One anchor client at 70 percent of capacity feels safe until they move the program. Two or three buyers in the same niche share the tooling, the fixtures and the inspection routine, so onboarding the next one is cheap.

  Check the buyer poolAt least 10 companies near you should buy that part type.

Engineers and sourcing staff screen shops against a short list. Machine travel and axis count come first, because a part that does not fit the envelope cannot be quoted. Then tolerance. A drawing calling for ±0.005 mm and Ra 0.8–1.6 μm needs a machine and a process that hold it every day, not on a good day.

Materials matter more than most shops expect. A buyer running 17-4PH or Ti-6Al-4V wants to see those alloys in your list, because cutting them changes tool life and fixturing. If your site only names aluminum, that buyer assumes you have never run stainless. State the grades: 6061, 7075, 303, 316L, 17-4PH, TC4.

Certifications decide who is even allowed to bid. Automotive work usually requires IATF 16949, medical work ISO 13485, and many buyers add ISO 9001 as a baseline. ISO 27001 matters when you hold their CAD files. A shop without the right certificate is removed before price is discussed.

Lead time and order size close the screen. Buyers want to know whether you take one prototype or only 500-piece runs, and whether you can ship in days or weeks. A shop that answers both questions on the same page saves the buyer an email, and that small saving is often why they send the RFQ to you.

Most shops lose work in the gap between receiving a drawing and sending a number. Fix that gap and you win jobs you never had a price advantage on. The package has four parts: a capability sheet, a standard quote form, a fixture and tooling list, and a sample inspection report.

The capability sheet is one page. List axis count, travel for each machine, spindle speed range, tolerance you hold in production, surface finish range, and the material grades you stock or buy weekly. Add your finishing options so the buyer does not have to find a second vendor for anodizing or black oxide.

The quote form should ask for the information you actually need: material and temper, quantity with a break at three levels, critical dimensions flagged on the drawing, finish callout, and the target date. When the buyer fills this in, you quote without a back-and-forth email chain. When they leave a field blank, you know the RFQ is not serious yet.

Keep a tooling list for your common families. If you already own the fixture for a 120 mm aluminum housing, the next RFQ in that family quotes without new tooling cost. That is the financial payoff of the niche you picked in the first section.

  Sample inspection reportProves you measure what you ship.

Winning the first order is the easy half. The second order depends on whether the parts arrived in spec and on time. Two habits decide this: in-process measurement and a realistic promise date.

Measure during the run, not only at the end. On a tight-tolerance feature, check the first part, then every tenth part, and log the number. If the dimension drifts halfway through the run, you catch it with 20 parts made instead of 200. On a 100-piece run of a ±0.02 mm bore, that habit is the difference between a profit and a rework bill.

Do not quote a date you cannot hold. If your machines are booked for four days, say five. Buyers plan assemblies around your date, and a shop that slips once is put on the backup list. A shop that ships early or on the promised day gets the next RFQ without being asked.

Inspection paperwork is part of the product. Send the dimensional report with the shipment, and note any dimension you measured with a different method. Buyers file that report, and when their own audit comes, your paperwork is what keeps you on the approved supplier list.
