Custom Tip Geometries: Drawing Submission Guide
Key Takeaway: Submit a dimensioned tip profile drawing (PDF/DXF) with tolerances, specify material and surface finish, and include the part drawing showing the internal feature. Custom tip core pins ship in 5–10 business days from drawing approval.
Drawing Requirements Checklist
- ☐ Tip profile — Fully dimensioned cross-section of the tip geometry
- ☐ Shaft diameter — Nominal diameter with tolerance (h6 or h7)
- ☐ Overall length — Pin head to tip end
- ☐ Tip tolerances — Geometric (concentricity, perpendicularity) + dimensional
- ☐ Surface finish — Ra value at the tip forming surface
- ☐ Material — SKH51, SKD61, or STAVAX ESR
- ☐ Coating — TiCN, DLC, or none
- ☐ Quantity — Including spare pins
Common Custom Tip Profiles
| Profile | Application | Manufacturing Method | Lead Time |
|---|---|---|---|
| Ball-end (spherical R) | Hemispherical cavities, lens housings | CNC turning + polishing | 3–5 days |
| Chamfered (C angle) | Entry chamfer for press-fit inserts | CNC turning | 3–5 days |
| Conical (taper point) | Tapered holes, alignment features | CNC turning | 3–5 days |
| Multi-step tip | Complex connector pin seats | CNC turning + grinding | 5–10 days |
| Contour profile | Custom internal shapes | EDM wire-cut or 5-axis CNC | 10–15 days |
Submission Process
- Step 1: Email drawing (PDF/DXF/STEP) to engineering team
- Step 2: Engineering review (1 business day) — we verify manufacturability and request clarification if needed
- Step 3: Quotation with confirmed lead time
- Step 4: Drawing approval — sign off on final dimensions before production
- Step 5: Manufacturing + inspection + shipping
Frequently Asked Questions
What information is needed to order custom tip pins?+
Dimensioned tip profile drawing (PDF/DXF), shaft diameter, length, material, tolerances, surface finish, and quantity. Part drawing showing the internal feature is helpful.
What tip profiles can be manufactured?+
Ball-end, chamfer, conical, multi-step, and custom contour profiles. Minimum feature size ~0.3 mm. EDM and 5-axis CNC for complex shapes.
How long does custom tip manufacturing take?+
5–10 business days standard. Simple profiles (chamfer, ball) 3–5 days. Complex profiles 10–15 days. Rush service 2–3 days at premium.
