CNC Turning Service for Shafts, Bushings, Pins, and Round Parts
CNC turning is the practical choice for round, cylindrical, threaded, grooved, and concentric components. MTSPi CNC machines shafts, pins, bushings, sleeves, spacers, collars, nozzles, inserts, connectors, and other precision turned parts for prototypes and low-volume production.
For accurate sourcing, the drawing should identify critical diameters, bores, threads, shoulders, grooves, runout, surface finish, and mating features. Our team reviews these details before quoting so the turning route supports fit, assembly, and inspection requirements.
Common turned parts
- Shafts, pins, bushings, sleeves, spacers, collars, threaded fittings, and inserts
- External turning, boring, facing, grooving, drilling, tapping, and threading
- Metal and plastic round components for prototypes and production
Buyer checks
- Diameter tolerance, bore size, concentricity, runout, thread class, and groove width
- Material behavior for wear, corrosion, friction, strength, and cosmetic finish
- Edge break and deburring requirements for assembly safety
Inspection options
- Micrometer, caliper, bore gauge, thread gauge, pin gauge, and runout checks
- CMM support for datum relationships when required
- First article inspection for repeat batches
CNC Turning Capability Guide
| Buyer need | MTSPi CNC support | Typical use case |
|---|
| Shafts and pins | Control outside diameter, shoulders, end features, grooves, and chamfers | Motion systems, fixtures, tooling, automation, and connectors |
| Bushings and sleeves | Control bores, wall thickness, concentricity, and surface finish | Wear surfaces, spacers, bearing supports, and alignment parts |
| Threaded parts | Internal and external threads, undercuts, lead-ins, and thread depth checks | Fasteners, inserts, fittings, nozzles, and assembly hardware |
| Prototype and low-volume turning | Flexible setup for samples and repeatable small batches | Engineering samples, repair parts, and bridge production |
Engineering and Sourcing Notes
Send CAD files, 2D drawings, material grade, quantity, tolerance notes, finish requirements, and inspection requirements. MTSPi CNC can review manufacturability, cost drivers, and quality risks before machining.

FAQ
What parts are best for CNC turning? CNC turning is best for shafts, pins, bushings, sleeves, spacers, collars, threaded fittings, inserts, nozzles, and other round parts.
Can turned parts include milled features? Yes. Flats, cross holes, slots, and side features may require secondary milling or mill-turn compound machining.
What information should I send for a turning quote? Send CAD files, 2D drawings, material grade, quantity, thread notes, critical diameters, runout requirements, surface finish, and inspection needs.
