Custom parts, precision requirements and production stages can involve the same machining processes. The route and scope are confirmed against your drawing, not by a category label.

CNC milling for housings, brackets and plates
A rotating cutter can create pockets, faces, slots and hole patterns. Start with the milling page when these features dominate your drawing. The accessible faces, inside corners and required datums should be reviewed together.
CNC turning for shafts, sleeves and bushings
A turning operation rotates the workpiece to generate round features. Review the outside diameter, bore, shoulder and thread requirements together. Flats or cross-holes may need an additional operation, so include the complete drawing.
A 5-axis review for angled features and tool access
Multiple faces and angled features may benefit from indexed 3+2 or simultaneous machining. The route depends on tool access, part geometry, fixturing and the required finish. Compare the options rather than assuming every complex part needs the same machine.
Process notes and reference reading
These are starting points for discussion, not an automatic machining recommendation. Review all features, datums, material and inspection requirements before confirming the route.
Reference reading: Sandvik Coromant — milling; general turning; Haas — 3+2 and simultaneous 5-axis machining.
Questions about CNC machining services
Which CNC machining services can I explore here?
The directory brings together CNC milling, turning and 5-axis machining, plus pages for custom parts, precision requirements and prototype-to-production orders. The CNC machining overview covers the complete order. These pages describe different ways to approach a project; the final scope is confirmed after reviewing your drawing.
Should I choose CNC milling or CNC turning for my part?
Milling uses a rotating cutter and is a useful starting point for pockets, faces and hole patterns. Turning rotates the workpiece to generate features such as outside diameters, bores and shoulders. A part with round diameters and flats or cross-holes may involve both. Compare milling and turning against your drawing, rather than choosing from the part name alone.
When should I consider 5-axis CNC machining?
Consider a 5-axis review when angled features, several machined faces or contoured surfaces make tool access and setup planning important. Indexed 3+2 machining and simultaneous 5-axis motion serve different needs. More axes are not automatically the best choice for every part. The 5-axis service page explains the distinction and the information needed for review.
Are custom and precision CNC machining different cutting processes?
No. Custom machining describes a part made to a particular specification; precision machining focuses on the dimensional and inspection requirements. Either can use milling, turning or a combination of operations. Use the custom parts page for the overall specification, and the precision page for critical features and acceptance criteria.
Can I discuss prototypes and production quantities together?
Yes. Include the sample quantity, any pilot batch, the expected production quantity and the dates you need reviewed. Identify what must be approved before the next stage starts. Forecast quantities should be distinguished from a released order. Use the prototyping and production page to outline the stages; capacity, quantities and timing remain subject to confirmation.
Which metals and plastics can I request for CNC machining?
The materials directory covers aluminum, stainless steel, steel, titanium, brass, copper and Inconel, together with PEEK, POM, nylon and acrylic. Specify the actual grade and condition, not just the material family. A listed material is not a stock guarantee; availability and suitability for your drawing must be checked.
What should I send for a CNC machining quote?
Send the current 3D model and a 2D drawing where needed to define tolerances, threads, finishes and inspection requirements. Include the material grade, quantity, drawing revision and requested delivery arrangement. List unresolved details rather than treating them as agreed. The RFQ checklist provides a practical starting point.
What tolerances can you achieve with CNC machining?
There is no single tolerance that should be promised for every part. The material, feature geometry, part size, fixturing, finishing and inspection method all need review. Mark the critical dimensions and the condition in which they will be measured. The precision machining page helps structure that discussion before a capability commitment is made.
Can surface finishing and inspection be included in the same inquiry?
Include them in the inquiry and identify the required final condition, coating or finish specification, masked areas and inspection records. Confirm the scope, responsible manufacturing or processing site and acceptance method before ordering. A requested treatment or report is not automatically included in a quote. The materials and design guide covers related drawing considerations.
What affects the price and lead time of CNC machining?
Material and blank size, programming and setups, cutting time, quantity, finishing, inspection and delivery requirements can all affect the quotation. Unresolved drawing details or approvals can also affect the schedule. Compare quotes for the same revision and scope; this directory does not calculate prices or promise delivery dates. See the costs and selection guide for a comparison checklist.
