CNC Machined 304 Stainless Steel Parts Manufactured in Accordance with Drawings from China
We are a China-based CNC machining workshop dedicated to 304 stainless steel machined components per drawing. From a single printed technical drawing, CAD model or physical sample, we produce custom CNC machined 304 stainless steel parts that follow every drawing specified dimension, geometric requirement, thread form, surface note and tolerance per drawing. Our 304 SS precision machining parts as per technical drawing serve machine builders, equipment manufacturers and maintenance teams across the world, covering custom turned & milled 304 stainless steel parts made on CNC lathes, machining centres and grinding equipment under one roof.
Whether the order is one machined stainless steel workpiece for a prototype run or a repeat batch of thousands of stainless steel components, every fabricated part is set up, machined, deburred, finished and inspected according to drawing before dispatch. Send a PDF print, DWG/DXF file, STEP/IGES model or a reference sample, and the same drawing is translated into a repeatable machining process for consistent mechanical parts and hardware parts, batch after batch.
Examples of Machined 304 Stainless Steel Workpieces
A selection of 304 stainless steel CNC machining components produced from customer-supplied drawings and samples, including threaded connectors, precision shafts, couplings and pipe fittings.
304 Stainless Steel Parts Made to Drawing or Replicated from Samples
We can machine all kinds of 304 stainless steel parts either from engineering drawings or from physical samples. Each route below is handled in-house with precision machining equipment, so custom drawing parts move from incoming file to finished workpiece without being passed between unrelated vendors.
Manufactured as per Drawing
PDF prints, DWG/DXF drawings and STEP/IGES models are reviewed feature by feature. Dimensions, tolerances, thread call-outs and surface requirements are all treated as drawing specified dimensions that the process plan must satisfy.
Custom Parts from Samples
When no drawing exists, a supplied sample is measured and reconstructed into a drawing for confirmation. Replacement, repair-copy or slightly modified stainless steel workpieces can be duplicated faithfully from the physical part.
Combined CNC Processing
Custom turned & milled 304 stainless steel parts are completed through linked CNC turning and CNC milling operations, preserving concentricity and position accuracy between turned diameters and milled flats, slots and cross holes.
One Piece to Large Batches
From a single one-off custom machined part to scheduled high-volume production, the same tooling strategy and inspection according to drawing standard is applied so that first articles and later batches remain interchangeable.
Common 304 Stainless Steel Machined Parts and Where They Are Used
304 (18/8 chromium-nickel austenitic stainless steel, also written 304 SS) is the default grade for general-purpose stainless steel components because it combines corrosion resistance, toughness, weldability and clean appearance. The following custom machined parts are produced routinely from 304 bar, tube, plate or forged stock.
Shafts & Stepped Shafts
Precision drive shafts, threaded shafts, eccentric shafts, long shafts and motor/pump shafts with ground diameters, keyways and retaining-ring grooves for power transmission and rotating equipment.
Bushings, Sleeves & Spacers
Wear bushes, guide sleeves, liner sleeves and precision spacers with tight inner/outer diameter control used to locate, support or separate moving mechanical parts.
Pipe Fittings & Connectors
NPT/BSP/G threaded fittings, quick connectors, hose adapters, tube fittings, elbows, tees, nipples and unions for fluid, gas, pneumatic and hydraulic lines.
Couplings & Adapters
Thread couplings, reducing couplings, shaft couplings and interface adapters that join different sizes, thread standards or component geometries within an assembly.
Flanges & Mounting Plates
Machined flanges, blanking plates, base plates and fixture plates with bolt-hole circles, counterbores and sealing faces for pumps, valves, piping and equipment frames.
Nuts, Inserts & Standoffs
Custom nuts, threaded inserts, standoffs, threaded sleeves and special fasteners with non-standard pitches, fine threads or unusual envelopes that catalogue hardware cannot cover.
Housings, Bodies & Blocks
Valve bodies, sensor housings, manifold blocks, small pump bodies and instrument enclosures with milled pockets, internal passages and sealing surfaces.
Pins, Rollers & Hardware
Dowel pins, clevis pins, hinge pins, conveyor rollers, brackets, clamps, knobs and other fabricated hardware parts requiring turning, milling, drilling and tapping in one workflow.
Precision Machining Processes for 304 Stainless Steel
A complete in-house process chain turns 304 stainless steel stock into finished stainless steel components. The twelve capabilities below are selected and combined according to each drawing's geometry, tolerance and finishing note.
CNC Turning
CNC turning produces rotational 304 SS parts: shafts, sleeves, rings, fittings and threaded components with controlled outer/inner diameters, grooves, chamfers and face features.
CNC Milling
CNC milling cuts flats, pockets, slots, keyways and hole patterns on prismatic stainless steel workpieces and on turned blanks that need secondary milled features.
3-Axis Machining
3-axis machining is the economical route for standard prismatic custom machined parts, covering planar milling, profiling, drilling and tapping from a single setup.
4-Axis Machining
4-axis machining rotates the part to machine sides, cross holes and radial features in one setup, improving positional accuracy on fittings, bodies and multi-face hardware parts.
5-Axis Machining
5-axis machining reaches complex contoured surfaces, angled holes and tightly related features on sophisticated 304 stainless steel CNC machining components with minimal refixturing.
Wire EDM
Wire EDM cuts narrow slots, sharp internal corners, profiled openings and hard-to-mill profiles in 304 plate and block with high profile accuracy and no cutting-force deflection.
Surface Grinding
Surface grinding refines mating faces and reference planes to fine flatness and low roughness where mechanical parts must seat or seal precisely.
Drilling & Tapping
Precision drilling and tapping create metric, unified and pipe threads (including NPT), cross holes, counterbores and threaded holes positioned exactly to the drawing.
Deburring
Thorough deburring removes sharp edges, machining burrs and cutting witnesses from every stainless steel component, with controlled edge breaks as noted on the print.
Finishing
General finishing covers cleaning, descaling, brushed finishes and uniform edge preparation so fabricated parts leave the workshop clean, dimensionally stable and ready to assemble.
Polishing / Bright Polishing
Polishing and bright polishing deliver smooth, reflective 304 SS surfaces for hygienic, visible or flow-contact parts, reducing surface roughness and improving cleanability.
Matte Finish
A matte finish (satin or bead-blasted appearance) provides a uniform non-reflective surface that hides tool marks and fingerprints on housings, brackets and decorative hardware.
Machining Floor and In-House Measuring Equipment
Production and inspection stay under the same roof: CNC milling and CNC turning create the features, while a 2D profile projector and a coordinate measuring machine verify that each finished workpiece matches the drawing.
CNC Milling Service
Vertical machining centres handle prismatic 304 SS components, pockets, profiles and hole patterns.
CNC Turning Service
CNC lathes turn rotational stainless steel workpieces, threads, tapers and precision diameters.
2D Profile Projector
Optical profile comparison checks small radii, angles, thread forms and delicate contours.
CMM Testing
Coordinate measuring captures position, true position and dimensional data for inspection according to drawing.
From Drawing Review to Inspection According to Drawing
Every order of 304 stainless steel machined components per drawing follows the same controlled sequence. The print remains the single authority for geometry, tolerance per drawing and acceptance criteria from first operation to final check.
Drawing Review
Each custom drawing part is reviewed for material call-out (304/304 SS), drawing specified dimensions, critical fits, thread standards, roughness notes and any features requiring clarification before cutting starts.
Process & Tooling Planning
Operations are sequenced between CNC turning, CNC milling, grinding or wire EDM, with fixturing, sharp tooling for work-hardening austenitic steel and coolant strategy selected to hold stable dimensions.
Tolerance per Drawing
Diameter tolerances, positional tolerances, fits, perpendicularity, concentricity and surface roughness are all held to the values stated on the print rather than to generic shop defaults.
In-Process Control
Operators check first pieces and adjust offsets during the run using micrometers, bore gauges, height gauges, thread rings/plugs and calipers, keeping every stainless steel workpiece inside spec.
Inspection According to Drawing
Final inspection walks through the drawing dimension by dimension; the 2D profile projector and CMM verify complex geometry, and results are recorded so batch parts are fully traceable to their print revision.
Finishing & Packing
Deburring, bright polishing or matte finish is applied as noted, parts are cleaned and protected against marking, and batches are labelled with part numbers and revisions for repeatable re-orders.
Why Designers Specify 304 Stainless Steel for Machined Components
Understanding the behaviour of 304 (also designated 1.4301 / SUS304 in many markets) helps us machine it correctly and helps designers choose it confidently for stainless steel components, mechanical parts and hardware parts.
Broad Corrosion Resistance
The chromium-nickel chemistry of 304 resists rust and atmospheric corrosion in everyday industrial, food, moisture and mild chemical environments, giving long service life without plating or painting.
Clean & Hygienic Surfaces
Smooth, non-porous and easy to clean — especially after bright polishing — 304 is widely used for fittings, valves, connectors and contact parts where residue build-up must be avoided.
Excellent Weldability
304 welds readily with common fusion methods, so machined stainless steel components can be integrated into welded frames, pipework and assemblies without sacrificing corrosion performance.
Toughness & Low-Temperature Strength
Austenitic 304 retains high ductility and impact toughness at room and sub-zero temperatures, making it suitable for cryogenic-style duties and parts that must not become brittle.
Good Formability
Before machining, 304 bar, tube and sheet form and machine predictably; in the annealed condition it is essentially non-magnetic, and it responds well to controlled feeds and sharp tools.
Machining Behaviour Managed
304 work-hardens under dull tools or slow rubbing cuts. We use rigid setups, sharp edges, appropriate chip loads and generous coolant to keep tight tolerances and clean finishes on every fabricated part.
From a Single Prototype to High-Volume Batch Production
Order quantity never changes the standard of workmanship. The same drawing, material and inspection logic scales across the four production modes below for custom CNC machined 304 stainless steel parts.
One-Off / Prototype
A single custom machined part or first article for fit-check, design verification or equipment repair, made directly to the supplied drawing or sample.
Small Batch
Small lots of stainless steel workpieces for pilot machines, spare-part kits or limited product series, with quick setup and consistent first-to-last quality.
Medium & Repeat Orders
Scheduled batches of mechanical parts and hardware parts; tooling, programs and inspection records are archived so every re-order matches the previous delivery.
Large-Volume Production
High-quantity runs of 304 stainless steel CNC machining components with optimised fixturing, cycle-time control and batch-level inspection according to drawing.
