Our Machining Process
After the metal spinning process is complete, parts often need secondary machining: facing an edge, holding an end thickness, drilling a hole pattern, or turning a register so the spinning will assemble.
That work is programmed on our in-house CNC plant — HAAS capacity plus CNC lathes, mills and drills — from the same project brief as the spin. It is not done on the spinning lathe. The spinning team still own the part: they check the blank has been formed correctly before it is set up for machining, and they check thickness and features again before it leaves quality control.
CNC mills, drills and lathes are what give the finished component its precision-engineering tolerances on diameters, holes and faces that spinning alone cannot hold.
What Machining Can Do For You
Machining is how Tanfield stays a single metal machining supplier from spun blank to finished part, instead of sending work out for holes and datums.
Practical gains are straightforward: the same fixture and programme can run a batch with consistent accuracy, including parts that are not a simple round; complex hole patterns and tight faces can be added to a spun or pressed shape without a second contractor. Scheduling stays in one factory, which is usually why customers specify machining here rather than only metal spinning.

Top things we get asked
At Tanfield, we offer machining services that use CNC metal spinning technology, including HAAS, CNC lathe, CNC drill, and CNC milling capabilities. These technologies provide additional precision and control over components after they’ve been spun. These services are part of a broader capability in metal fabrication, including precision engineering and laser cutting.
At Tanfield, we uphold strict quality inspections, and adherence to ISO standards, and advanced technology helps to ensure every component meets customer specifications.
If you do not have a drawing, our technical engineering department will supply a drawing upon your request for a quote, at no additional cost. This drawing can be signed off before placing an order.
Tanfield serves a variety of industries that require high-quality, precise metal fabrication. These include sectors such as agriculture, air movement, renewable energy, safety, pressure vessels, food industry, and playground. Tanfield offers versatile services, including metal spinning, swaging, and machining, to meet the range of needs of each sector.
All parts manufactured from Tanfield will have full traceability, all materials that require certification will be automatically sent to our customers on completion of the order.
Tanfield’s standard tooling stock is the largest in the country and we invest in it on a yearly basis. If your project requires new tooling Tanfield will look at the most cost-effective way to service our customers’ needs.
Yes. We regularly combine machining with metal spinning to deliver fully finished components. This integrated approach improves accuracy, reduces lead times, and ensures consistency across the entire manufacturing process.
Our CNC machining capabilities allow us to work to tight tolerances, depending on material, geometry, and component size. Precision checks are built into our quality control process to ensure all specifications are met.
Where suitable, we can machine customer-supplied spun or formed components. Our team will review your requirements and materials to confirm suitability before work begins.
Absolutely. CNC milling, drilling, and turning enable us to machine complex features, intricate profiles, and irregular geometries that would be difficult to achieve through forming alone.
After spinning, machining is used for features the lathe cannot hold: end or flange thickness, a turned register or weld prep, hole patterns, slots, and facing the rim of a dished end or tank head so it sits square on a shell. That is common on pressure-vessel heads, cones and covers. We programme the job on CNC lathes, mills and drills (including HAAS), not on the spinning machine. If the only requirement is the spun shape, machining is omitted.
No. CNC / PNC spinning forms the blank over a tool to make the round or dished shape. CNC machining (turning, milling, drilling) then cuts or faces that part to a drawing tolerance. Tanfield does both in-house as a metal machining supplier for spun and pressed work, which is why precision-engineering features can be added without sending the component out. Use spinning for the form; use machining for holes, faces and thickness control.
