CNC Turning
Turning cuts round stainless parts and their threads from bar. Pins, shafts, spacers, and bushings are made this way.
CNC Turning Parts →
Profab turns, mills, drills, and taps stainless steel parts at our own CNC shop in Fenghua, Ningbo. Sheet parts are stamped and bent at the same factory. Each part is made to your drawing, your sample, or a worn part you send us.
Send STEP, IGES, DXF, DWG, or PDF drawings, or a physical sample.
Turning, milling, drilling, tapping, bending, and stamping are carried out at our factory. Welding and laser cutting are offered with your order. Each card links to the service page that covers it.

Milling cuts flats, slots, pockets, and hole patterns into bar or plate. Parts that need 5-axis work can be quoted on request.
Custom CNC Parts →
Holes are drilled to the positions on your hole chart. Cross holes in turned parts are drilled in a second setup.
Custom CNC Parts →
Internal threads are tapped to the callout on your drawing. Screws and studs then fit straight into the part.
Custom CNC Parts →
Bending forms stainless sheet and bar to the angle on your drawing. Brackets, clips, and covers are typical bent parts.
Sheet Metal Parts →
Stamping cuts and forms flat stainless parts from sheet. Washers, tabs, and small brackets are common examples.
Sheet Metal Parts →
We offer TIG and MIG welding for assemblies that join machined and sheet components.
Sheet Metal Parts →
Laser cutting of sheet and plate blanks is available on request before bending or machining.
Sheet Metal Parts →Find the row closest to your part. The third column names the route, and the last column links product pages made the same way.

Pick the grade for the environment the part works in, then confirm it against the drawing.
| Grade | Minimum yield strength | Pitting resistance (PREN, typical) | Typical use |
|---|---|---|---|
| 304 | 205 MPa | 18 to 20 | Dry and fresh-water parts |
| 316L | 170 MPa | 24 to 26 | Marine, washdown, and welded parts |
| 17-4PH (H1025) | 1000 MPa | Lower than 316L | Pins, shafts, and wear parts |
| Duplex 2507 (on request) | 550 MPa | 40 or higher | High-load parts in chloride service |

Values are typical minimums for annealed plate and for 17-4PH in the H1025 condition, given for comparison.
Heat treatment for 17-4PH is available on request. We agree the condition with you before machining.
Name the finish when you send the drawing. We price it together with the machining.
Passivation after machining removes free iron left on the surface by cutting tools.
We offer / Machined partsElectropolishing smooths the surface of a machined part, including small features and edges.
Electropolishing Services →We offer / Smooth surfaceMirror polishing gives a bright, reflective surface for parts that stay in view.
Mirror Polished Stainless Steel →On request / Visible partsSandblasting leaves an even matte surface with low glare.
Sandblasted Stainless Steel →On request / Matte surfacePowder coating adds a colored layer where a part needs one.
Powder Coating →On request / ColorTell us where the part works and how it should look. We suggest a finish when we quote.
Ask with your quoteA finish adds or removes a little material, so state it on the drawing before we quote.
Tell us which dimensions matter. We plan the setup around them.
What a feature can hold depends on its size, its shape, and the grade.
Each industry page shows the grades and the parts that suit its conditions.
Cleats, shackles, and linkage ends are machined in 316L for parts that sit in salt spray.
Marine parts →Spacers, clamps, and conveyor hardware in 304 or 316L suit washdown lines.
Food parts →Rod ends, tie rod ends, and exhaust flanges are made for road and off-road vehicles.
Automotive parts →Bushings, spacers, and linkage parts serve machinery that runs wet or dirty.
Industrial parts →Brackets, spacers, and threaded rod go into tracker and racking hardware.
Solar parts →Ground equipment linkage, spacers, and brackets are machined to your drawing.
Aerospace parts →Linkage, pivots, and frame hardware fit beds, lifts, and lab equipment.
Medical parts →We CNC machine your parts ourselves at our factory in Fenghua, Ningbo. Questions about a drawing go straight to the people who cut the metal.
Most orders start from a drawing. A sample or a worn part works too, because we measure it and quote a copy.
There is no hard minimum. Prototype runs typically start around 100 pieces. Turned pins, milled brackets, and bent covers for one assembly can share one quote.
Send the drawing file, a sample, or a worn part. Add the grade, finish, quantity, and critical tolerances.
Engineering reviews the part for manufacturability and replies with a quotation. Prices can be shown at several quantity tiers.
Before sampling, we confirm the drawing revision, grade, finish, and quantity with you.
Samples are made for you to check against your drawing before the full run starts.
The full batch follows the approved sample. Finished parts ship by sea, air, or express courier.
Repeat orders are quoted against the approved drawing. Tell us if anything has changed since the last run.
Short answers to the first engineering and purchasing questions.
We supply 304, 316L, and 17-4PH regularly. Other stainless grades, such as duplex 2507, are available on request.
Turned and milled features are typically held to ±0.01 mm (about ±0.0004 in). The figure depends on the feature, the part size, and the grade. Mark the critical dimensions on your drawing.
Yes, 5-axis machining is available on request when a part needs it. Whether your part needs it depends on the drawing.
We offer passivation, electropolishing, and TIG and MIG welding. Mirror polishing, sandblasting, powder coating, heat treatment, and laser cutting are available on request. Each one is quoted together with the machining.
Quantities vary by product, with no hard minimum. Prototype runs typically start around 100 pieces.
Yes. We measure the sample and quote a copy. Tell us the grade you want to use.
Round parts on one axis, such as pins, shafts, and spacers, are turned. Blocks, plates, and multi-face parts are milled. Flat parts bent from sheet go to sheet metal. When a part needs two routes, the drawing sets the order.
