Visible Part Families
1. Threaded Shafts and Pins
The image shows elongated cylindrical components with stepped diameters and external threaded ends. These geometries are suitable for shafts, pins, spacers, connectors and custom threaded shafts and bushings. Thread length, major diameter, minor diameter, shoulder position and end treatment should be stated on the supplied drawing.
2. Sleeves and Bushings
Short cylindrical components with internal bores, external shoulders and smooth turned surfaces can be developed as sleeves, spacers, bushings or precision turned sleeves and collars. The final design depends on the required bore, outer diameter, fit relationship and operating environment.
3. Flanges and Collars
The pictured parts include wider flange sections and ring-like collars. They can be produced as custom flanged turned parts with drawing-defined flange diameter, thickness, bore, counterbore, groove, shoulder and fixing-hole details.
4. Threads, Bores and Cylindrical Features
External threads, internal bores and stepped transitions are visible across the product family. The service also covers CNC machined pins and cylindrical parts. Thread standards, pitch, tolerance class, thread depth, thread relief and inspection method should be clearly stated in the drawing.

Material and Finish Confirmation
The supplied image shows metallic turned components, but it does not identify the exact material grade or surface treatment. Material and finish must therefore be confirmed by drawing, sample or purchase specification before production.
| Confirmation Item | Options to Discuss | Information Required |
|---|---|---|
| Material family | Stainless steel, alloy steel, aluminum, brass or other specified metal | Grade and material condition |
| Corrosion environment | Indoor, outdoor, humid, chemical or high-temperature use | Working environment |
| Appearance | Machined finish, polished, brushed, plated or coated | Visual sample or finish specification |
| Thread system | Metric, inch or customer-specific standard | Standard, pitch and tolerance class |
| Fit requirement | Clearance, transition, interference or bearing fit | Mating-part information |
| Inspection | Critical dimensions, gauges or inspection report | Inspection plan |
Drawing-Based CNC Lathe Service
Our drawing based CNC lathe service starts with the customer’s drawing or approved sample. We review the geometry, identify critical dimensions and return questions before production. This helps reduce avoidable changes during machining and supports more consistent production for OEM turned metal components.

FAQ
Q1. What does “manufactured to supplied drawings” mean?
It means that the part is produced according to the customer’s approved drawing rather than selected only from a fixed catalog. The drawing should define geometry, dimensions, tolerances, threads, material and finish requirements.
Q2. What types of CNC turning machining parts can you make?
The visible product family includes threaded shafts, stepped pins, sleeves, bushings, collars, flanges, bored cylinders and other axisymmetric metal components. We also make CNC machined pins and cylindrical parts from approved drawings.
Q3. Can you manufacture parts from a sample instead of a drawing?
Sample-based development can be discussed. A physical sample helps confirm the external form, but a drawing or technical specification is recommended for critical dimensions, material, thread details and performance requirements.
Q4. Which drawing information is needed for a CNC turning quotation?
Please provide the part drawing, material grade, quantity, critical tolerances, thread specification, surface finish and inspection requirements. Our drawing based CNC lathe service uses these details to review manufacturability before quoting.
Q5. Can you customize threaded shafts, bushings and flanges?
Yes. We can make custom threaded shafts and bushings, precision turned sleeves and collars, and custom flanged turned parts according to the approved drawing.
Q6. What materials are available for turned components?
Material selection depends on the application and drawing. Common directions may include stainless steel, alloy steel, aluminum or brass, but the exact grade should be confirmed before production rather than assumed from the product image.
Q7. Can you provide prototypes or small batches?
Prototype and small-batch production can be evaluated according to part complexity, material, quantity and inspection requirements. This includes prototype CNC turning for industrial parts.
Q8. Can packaging and labels be customized?
Yes. Bulk packing, individual packing, part-number labels, batch labels, barcodes and customer-specific packing instructions can be discussed for OEM turned metal components.
Q9. How should I confirm the material and finish?
State the material grade and finish directly on the drawing or purchase specification. If the drawing is incomplete, missing information can be identified before production.
Q10. What is the difference between CNC turning and CNC milling?
CNC turning is primarily used for rotational parts such as shafts, pins, sleeves, collars, flanges and cylindrical housings. CNC milling is normally selected for prismatic parts, pockets, slots and non-rotational profiles.
Send your drawing or approved sample for a drawing-based CNC turning review. Tell us the material, quantity, critical dimensions, thread requirements, surface finish and inspection needs. We will help evaluate the manufacturing route for your custom CNC turned components.
