C14500 Copper CNC Machining for Detailed Conductive Parts
Fine threads, cross holes and slender contact pins need a stable turning route. We review C14500 bar condition, feature access and finishing allowance around your conductive component.

Our review links the feature that matters in your assembly to the proposed setup, machining sequence and acceptance check.
| Your part challenge | Our proposed approach | How to verify the result |
|---|---|---|
| A slender pin deflects during turning | Assess bar support, feature order and turning or Swiss-type route suitability. | Check the functional diameter and specified geometric relationship. |
| A cross hole leaves a contact-area burr | Keep an accessible deburring and cleaning step in the sequence. | Define the hole-edge and contact-area acceptance criteria. |
| Plating changes a fine thread | Review allowance and coating distribution before cutting the thread. | Inspect the thread in its required final condition. |
ILLUSTRATIVE ENGINEERING BRIEF
A C14500 contact pin with a cross hole and fine thread
Illustrative RFQ: 500 pins, 35 mm overall length, a Ø4 mm shank, M3 thread and Ø1.5 mm cross hole. Plating is specified on the finished component.

These numbers describe an example customer requirement, not a completed customer project or a guaranteed machining limit. Final feasibility is confirmed from the drawing.
The engineering challenge
Feature order affects support and burr access. Fine-thread acceptance can change after plating even when the uncoated thread gauges correctly.
The acceptance plan
Proposed acceptance: shank and hole dimensions, specified runout, final thread gauge and contact-edge condition after the agreed finish.
A proposed machining route
- Review bar condition, current-carrying area and the plating specification.
- Compare supported turning and a Swiss-type route against geometry and quantity.
- Sequence the cross hole, thread and cut-off to retain practical deburring access.
- Approve a plated first-off part against thread and contact-surface requirements.
What our engineering review
brings to your quotation
Choose the support route
Compare turning approaches for slender features.
Sequence for burr access
Keep cross holes and contact edges inspectable.
Approve after plating
Use the required finished thread and contact condition.
Material selection
supports the part.
Confirm the grade after the functional requirements are clear.
Use the exact C14500 or CuTeP designation, governing standard and temper. Conductivity and joining requirements remain part of the material decision.

Questions about your machining project
When is a Swiss-type route worth considering?
Quantity, bar diameter, slenderness and feature layout influence the decision. Send the drawing for a route comparison.
Can C14500 replace C110 in my part?
Only after conductivity, joining, material standard and functional requirements are reviewed and substitution is approved.
How should fine plated threads be specified?
State the thread standard, final gauge requirement, plating specification and any masked areas.
Are the example parameters a guaranteed capability?
The example is a customer brief used to explain the proposed engineering route. Actual limits, cost and timing are confirmed from the complete drawing.
What should I include for this process review?
Send the CAD and drawing revision, exact grade, quantity and the critical requirements discussed above. Include mating-part details and required inspection records.
