FAQ
Q1. What are OEM precision metal parts?
OEM precision metal parts are drawing- or sample-based components manufactured for integration into an original equipment assembly. They may include brackets, sleeves, shafts, bushings, housings, fittings and inserts.
Q2. Can you machine stainless steel, aluminum, titanium and brass?
These materials can be reviewed as project-specific material directions. The exact alloy, temper or grade, machining requirements, finish and inspection criteria must be confirmed before production.
Q3. What is CNC stainless steel machining used for?
CNC stainless steel machining is used to produce components such as sleeves, shafts, housings, fittings, brackets and inserts when the project requires a stainless steel material direction. Final suitability depends on the selected grade and application environment.
Q4. Can the parts be made from customer drawings or samples?
Yes. A 2D drawing, 3D CAD file, sample or BOM can support quotation, process planning and production review. Critical fits are best controlled with dimensioned technical data.
Q5. Can one order combine different materials?
A project may include stainless steel, aluminum, titanium, brass or other specified materials across different part numbers. Each part should have a clear material and finish requirement in the BOM or drawing.
Q6. Are the copper-colored parts definitely brass?
No. A copper-colored appearance does not prove a brass material. The actual material must be confirmed through the customer specification or material documentation.
Q7. Can internal and external threads be customized?
Yes. Thread standard, diameter, pitch, length, engagement and mating component should be provided. Internal threads and external threads should be listed separately in the drawing or BOM.
Q8. Can small cylindrical inserts and bushings be produced?
Yes. The image shows small cylindrical parts, bushings and threaded inserts. Bore, outside diameter, length, fit, material and installation method should be defined.
Q9. Can the visible colors be matched?
Color matching can be discussed using a reference sample or color requirement. The final result depends on the substrate and selected process, such as anodizing, plating, coating or another treatment.
Q10. Can you add text or a product mark?
Marking can be reviewed for text, part number, logo, batch or revision. The visible TRAVEL LOCK text is treated as image content only and is not assumed to be the required customer marking.
Q11. Can you supply prototypes and small batches?
Prototype, first-article and small-batch production can be reviewed according to geometry, material, setup, inspection and quantity requirements.
Q12. What information is required for a quotation?
Provide a drawing, CAD model, sample or BOM, together with material, quantity, critical dimensions, tolerance, thread, finish, marking, inspection and packing requirements.
Q13. Does the image prove a specific tolerance or grade?
No. The image shows part forms and visible finishes only. It does not prove a numeric tolerance, material certificate, hardness, equipment accuracy or inspection result.
Q14. How are repeat OEM orders controlled?
Repeat orders can be managed through an approved drawing or sample, revision record, material specification, process notes, inspection points, marking and packing instructions.
