FAQ

Q1. What is turn mill machining?

Turn mill machining combines rotational machining features with milled, drilled, bored, threaded or slotted features within one coordinated CNC project. It is suitable for parts that are more complex than a simple turned shaft or a simple milled plate.

Q2. What parts can be made through this service?

The image shows brackets, sleeves, flanged housings, clamps, linkage plates, shafts, threaded fittings, knobs, rings, covers, slotted plates and small inserts. Final part types depend on the drawing, material and project requirements.

Q3. What does a one stop CNC machining service include?

It can coordinate drawing review, process planning, turning, milling, drilling, boring, threading, deburring, specified finishing, inspection, labeling and packing. The exact scope is confirmed for each project.

Q4. Can you process custom non-standard metal parts from a sample?

A sample can support an initial review or replacement-part discussion. For repeat production and critical interfaces, a dimensioned drawing or CAD file provides stronger control.

Q5. Are the colors in the image standard finishes?

No. The colors are visual references. The actual material, anodizing, plating, coating or other process must be specified and approved before production.

Q6. Can one order include both turned and milled components?

Yes, a project can include different component families when the BOM, drawings, quantities, material and inspection requirements are clear. The supply scope should be confirmed before quoting.

Q7. What information is needed for a quotation?

Send a drawing, 3D CAD file, sample or BOM, together with material, quantity, critical tolerances, threads, surface direction, inspection requirements and packing instructions.

Q8. Can holes, slots and internal threads be customized?

Yes. Hole diameter, location, depth, slot geometry, internal bore, internal thread and mounting pattern can be defined by the technical drawing.

Q9. Can knurled knobs and manual adjustment parts be made?

Knurled cylindrical parts and adjustment components are visible in the image. Knurl pattern, pitch, grip diameter, bore, thread and operating interface should be specified.

Q10. Can you support prototypes and small batches?

Prototype, pilot and small-batch projects can be reviewed according to geometry, material, setup, inspection and quantity requirements.

Q11. Can surface colors be matched to a sample?

A color or finish sample can support discussion, but the final match depends on the substrate, selected process, reference standard and approved sample.

Q12. How do you manage repeat orders?

Repeat supply can use an approved drawing or sample, revision record, material direction, process notes, inspection points and packing instructions to improve consistency.

Q13. Does the image prove high precision or a specific tolerance?

No. The image shows product forms and machining appearance but does not establish a numeric tolerance, equipment accuracy or inspection result. Precision requirements must be stated in the drawing and verified through agreed inspection.

Q14. Can parts be packed by part number or assembly group?

Part-number labels, batch separation, assembly-group packing, trays, bags and other packing directions can be discussed when the BOM and packing instructions are supplied.
