CNC Titanium TI6AL4V Milled Parts

Project Overview:

Material: Grade 5 Titanium Alloy TI6AL4V
Manufacturing Process: CNC Machining, Turning, Wire Cutting
Surface Finishing: Beadblasting, Brushing, PVD Coating, Laser Engraving
Quantity: 100 Units (30 Units PVD Coated, 70 Units Brushed)
Lead Time: 20 Days

To get high quality, lightweight, durability for this Pen, customer changed aluminum or stainless steel to grade 5 titanium alloy TI6AL4V for its properties of high strength-to-density ratio and better corrosion resistance.
Project Challenges:

1. Titanium alloy had fairly low thermal conductivity that probably resulted in burning or chip adhesion to cutting tool during milling.

2. Titanium alloy had less stiffness than many other metals, which led to the risk of distortion and cutting tool jarring during the milling.

3. Seamless alignment between Cap and Housing of this Pen was the key challenge that the rapid prototypes delivered this point.

CNC aluminum prototype   aluminum prototype testing   Prototype to Production Step By Step:

Firstly, an aluminum prototype was milled to verify appearance and seamless alignment, the aluminum prototype delivered feasibility of seamless alignment, then two titanium milled prototypes were followed for final testing.
CNC titanium prototypingThe titanium prototypes exposed the difficulty of seamless alignment. Then we offered a solution of slightly revising the Cap and Housing's design.
CNC titanium milled prototypeAnother titanium prototype was milled to test how the solution worked, and excellent seamless alignment proceeded with the low volume production.
CNC titanium partsThe titanium prototypes manufacturing acted as a good instruction for the low volume production that went on smoothly and efficiently.
CNC titanium milled penCNC titanium milled pen. The smoothly streamlined surface and seamless alignment had this pen looked unique, quality and elegant.
CNC titanium machined partsThe finished titanium Pens. Each Pen went through strict quality inspection in appearance and seamless alignment, the substandard ones were sorted out for repair or remake.
CNC titanium millingBeing different to milling the other common metals, milling titanium alloy had more requirements for the heat dissipation and milling stability.
