Custom CNC Turning Services
Weldo produces shafts, bushings, pins, sleeves, threaded parts and custom fittings in metals and engineering plastics, from prototypes to repeat production.
*Capacity and achievable tolerance depend on alloy, stock size, feature geometry, length-to-diameter ratio and inspection method.
How CNC Turning Works
The chuck or collet rotates the workpiece while programmed tools move along radial and axial paths. A controlled sequence can create diameters, tapers, grooves, bores, threads and cut-off features in one setup.
Setup and Datum
Stock, grip length, runout and reference faces are established.
Rough Turning
Material is removed with stable chip and heat control.
Finish Features
Critical diameters, grooves, threads and bores are completed.
Проверка
Datums and critical dimensions are checked before release.
Materials for CNC Turning
Material selection considers load, wear, corrosion, temperature, moisture, conductivity, chip behavior and dimensional stability.
Алюминий
6061, 7075, 2024, 5052, 6063 and tooling plate.

Confirm the exact grade, temper or filler—not only the material family. Regulated applications also require the applicable traceability and supporting documentation.
CNC Turning Tolerances and Design Guide
Use these values for early design planning. Final capability is confirmed from the drawing, material, feature geometry and inspection plan.
| Артикул | Возможности | Design Note |
|---|---|---|
| Maximum turning envelope | Up to Ø500 mm × 1200 mm length | Machine availability, chucking and part mass must be reviewed. |
| Minimum diameter | From approximately Ø1 mm | Depends on material, feature length, workholding and inspection. |
| General dimensional tolerance | Typically 0.01 mm | Apply drawing dimensions, datums and inspection conditions. |
| Reviewed tighter tolerance | Down to ±0.005 mm on suitable features | Not a universal tolerance; subject to engineering review. |
| Recommended metal wall | About 0.7 mm or greater | Thin walls may deflect or distort during clamping and cutting. |
| Recommended plastic wall | About 1.5 mm or greater | Material stiffness, heat and moisture behavior must be considered. |
| Threads | Internal and external; M1–M50 capability | Diameter, pitch, class, relief and gauge method must be specified. |
| Deep holes | Prefer depth ≤5× diameter | Up to 10× diameter may require a dedicated process review. |
ISO 2768 general tolerances apply only when invoked by the drawing or project specification. They do not replace explicit critical dimensions or GD&T.

Why Work With Weldo for CNC Turning?
Projects are reviewed for material, chucking, runout, tool access, tolerance, finish allowance and inspection before production.
DFM Review
Wall thickness, grooves, reliefs, threads and length-to-diameter risks are checked.
Планирование процессов
Turning, milling, grinding, heat treatment and finishing are sequenced together.
Поэтапная проверка
Runout, diameters, thread gauges and critical dimensions are monitored.
Repeat Production
Controlled programs and inspection records support recurring batches.
Часто задаваемые вопросы
Concise guidance on part geometry, tolerances, materials, slender components and quote files.
What parts are best suited to CNC turning?
Shafts, pins, bushings, sleeves, rings, fittings and other parts dominated by rotational geometry are strong candidates.
Can turned parts include flats, slots or cross holes?
Yes. Live tooling or a secondary milling operation can add non-rotational features when tool access and datum control permit.
How tight can CNC turning tolerances be?
General capability is typically around 0.01 mm. Selected features may be reviewed to ±0.005 mm depending on material, geometry, size and inspection method.
Which materials can be CNC turned?
Common choices include aluminum, stainless steel, steel, copper alloys, titanium, POM, PEEK, PTFE, ABS and other engineering plastics.
How do you control long, slender parts?
Tailstocks, steady rests, reduced cutting forces, staged machining and runout inspection help control deflection and vibration.
What files are required for a quote?
Provide a STEP or IGES model plus a PDF or DWG drawing showing datums, critical tolerances, threads, finish, material and quantity.
