Cutting a rotating workpiece to a diameter on a lathe. The minimum order is 2,000–5,000 pieces and samples follow within 7 days of the drawing being approved. Cutting a rotating workpiece to a diameter on a lathe. The base process for anything cylindrical. On a CNC lathe with driven tooling it will also drill, mill a flat, cross-drill and thread without the part being moved, which is what makes it the usual route for a one-piece machined component. Turning removes material, so it costs more in stock than forming does and is chosen for precision, for short runs and for shapes that cannot be formed. ## What Turning is the right choice for - Precise diameters and shoulders - Short and medium runs - Parts combining several features on one axis ## Where it is the wrong choice - Material becomes swarf, so cost scales with how much is removed - Slower per part than cold forming at volume ## Parts produced this way - [Custom Machined Component](https://engineeringhardware.com/custom/components/) — [11 standard parts in the catalog](https://engineeringhardware.com/fasteners/components/) - [Custom Shaft Collar](https://engineeringhardware.com/custom/shaft-collars/) — [4 standard parts in the catalog](https://engineeringhardware.com/fasteners/shaft-collars/) - [Custom Standoff & Spacer](https://engineeringhardware.com/custom/standoffs-spacers/) — [14 standard parts in the catalog](https://engineeringhardware.com/fasteners/standoffs-spacers/) - [Custom Pin](https://engineeringhardware.com/custom/pins/) — [43 standard parts in the catalog](https://engineeringhardware.com/fasteners/pins/) ## Usually combined with Turning is rarely the only operation on a part. On most jobs it sits in a sequence with: - [CNC Machining](https://engineeringhardware.com/custom/cnc-machining/) - [Thread Turning](https://engineeringhardware.com/custom/thread-turning/) - [Centerless Grinding](https://engineeringhardware.com/custom/centerless-grinding/) ## Order terms - **Minimum order:** 2,000–5,000 pieces. The exact figure depends on the part: it is set by the tooling the drawing calls for, and is confirmed when the drawing has been reviewed. - **Samples:** Within 7 days of drawing approval. - **Drawing:** Preferred, but not required — a sample, photographs or a sketch is enough to start. ## What a quotation needs Nine things, and a drawing settles most of them at once. Where a field is unknown, say so — an assumption stated is better than a blank, and several of these can be recommended rather than specified. - **Drawing:** A 2D drawing (PDF or DWG) or a 3D model settles almost every other question on this list at once. - **Dimensions:** Diameter, length, head size and any features — enough to know what is being made. - **Tolerance:** Tolerance is the single biggest cost driver. Tell us which dimensions are critical and which are not — holding everything tight costs money on features nobody measures. - **Material:** Carbon steel, alloy steel, stainless, brass, aluminium, titanium — or the application, and we will suggest one. - **Strength grade:** Property class to ISO 898-1 (8.8, 10.9, 12.9) or stainless class to ISO 3506 (A2-70, A4-80). This decides the material and the heat treatment together. - **Thread standard:** Metric coarse, metric fine, UNC, UNF, BSW or a pipe thread — and the tolerance class if it is specified. - **Surface finish:** Zinc, hot-dip galvanised, black oxide, Dacromet, Geomet, nickel, passivation, or plain. Salt-spray hours if you have a requirement. - **Quantity:** Annual volume and first-order quantity. Volume changes which process is the right one, so it changes the price more than most buyers expect. - **Application & environment:** What the part holds together, and what it has to survive — temperature, vibration, chemicals, salt. This is what lets us catch a specification that will not work before it is made. ## Draw it here No CAD, no account, nothing to install. Draw the part in your browser, generate a real ISO metric thread from M1 to M100 with the end treatment it needs, dimension it, and export a PDF or a DXF to attach below. Sheets run to two metres for long studs and threaded rod. Open the drawing builder ## Questions ### What is the minimum order quantity for a custom part? Between 2,000 and 5,000 pieces for most parts. The exact figure depends on the part: it is set by the tooling the drawing calls for, and is confirmed when the drawing has been reviewed. ### How long does a sample take? Within 7 days once the drawing has been approved. The drawing stage comes first, and for a part being reverse-engineered from a sample it is where most of the time goes. ### Can you make a part without a drawing? Yes. A physical sample, photographs against a scale, or a dimensioned sketch are all workable starting points. A drawing is produced from whichever of those you have and sent back for approval before anything is made. ### When is Turning not the right process? Material becomes swarf, so cost scales with how much is removed. Slower per part than cold forming at volume. ### Which fasteners are made by turning? In this catalog: machined component, shaft collar, standoff & spacer, pin. Whether it is the right process for a particular part depends on the drawing and the quantity. ## Parts of this kind we already make Showing 36 of 39 089 – Phillips Countersunk Self-Tapping Screw — GB／T 846 ／ ISO 7050 (Series 028) — GB／T 846 ／ ISO 7050 093 – Phillips Pan Head Self-Tapping Screw — GB／T 845 ／ ISO 7049 (Series 032) — GB／T 845 ／ ISO 7049 103 – Clamping Handle Screw (Short) — DIN 6336 ／ GN 313 (Series 042) — DIN 6336 ／ GN 313 104 – Clamping Handle Screw (Medium) — DIN 6336 ／ GN 313 (Series 043) — DIN 6336 ／ GN 313 105 – Clamping Handle Screw (Long) — DIN 6336 ／ GN 313 (Series 044) — DIN 6336 ／ GN 313 106 – Sheet-Metal Self-Tapping Screw — GB／T 845 ／ ISO 7049 (Series 045) — GB／T 845 ／ ISO 7049 Ball-Lock Pins Ball-Lock-Pins-Applications Browning-Compatible-Shear-Pins Clevis Pin — ISO – DIN (Series 101) — ISO – DIN Clevis Pin — ISO – DIN (Series 105) — ISO – DIN Clevis Pin — ISO – DIN (Series 150) — ISO – DIN Coiled-Spring-Pins Cross-Flat-Head-Knurled-Self-Tapping-Screws din-6340-heavy-duty-clamping-washer Dowel Pins — ISO 8734 ／ DIN 6325 Dowel Pins — ISO 8734 ／ DIN 6325 Applications1 Dowel Pins — ISO 8734 ／ DIN 6325 Detail Gas-Nails-Gas-Drive-Pins Gravity-Pins Grooved-Pins Hardened-Ground-Dowel-Pins Hitch Pins HVAC-Duct-Insulation-Stick-Pins HVAC-Duct-Insulation-Weld-Pins Internally Threaded Dowel Pin — GB – T 120.1 – ISO 8735 (Series 099) — GB – T 120.1 – ISO 8735 Internally Threaded Dowel Pin — GB – T 120.1 – ISO 8735 (Series 100) — GB – T 120.1 – ISO 8735 iso-13337-light-duty-slotted-spring-pin iso-2338-parallel-dowel-pin iso-2340ab-headless-clevis-pins iso-2341a-clevis-pin-with-head iso-8736-taper-pin-internal-thread iso-8737-taper-pin-external-thread iso-8738-flat-washer-for-clevis-pins iso-8739-full-length-grooved-pin-with-pilot iso-8741-8745-solid-grooved-pin-family These are catalog parts, shown to say what the tooling already covers.
