Machining Capabilities for High Performance Parts

Posted On April 4, 2017 By Tony Holtz

Do you know how machining a part from titanium can improve its functionality and performance? How about using key inserts for improved durability to your part. Here are few capabilities and design options to keep in mind for your next machined part.

Titanium machined parts.

Let’s start off with some big news. Previously, we only offered titanium for 3D-printed parts, but it’s now available to customers for machined parts. And, if that wasn’t enough to catch your attention, how does titanium machined parts in as fast as three days sound?

Titanium is extremely strong and boasts a high strength-to-weight ratio. It also has excellent corrosion resistance, high operating temperatures (up to 1,000°F) and is nontoxic.

Titanium has range of applications due to its advanced material properties. Frequently, you’ll find titanium parts in the aerospace, medical, military and marine industries. More specifically, it’s used for parts like rotors, compressor blades, hydraulic systems, surgical equipment, dental and orthopedic implants as well as in military aircrafts due to excellent ballistic characteristics.

The only drawback is the cost of the raw material. It’s more expensive than steel. For this reason, most manufacturers don’t hold a lot of inventory, but that isn’t the case at Protolabs. We maintain a level of inventory that allows for on-demand milling and turning of titanium parts

Key inserts add durability and strength.

Key Inserts
Key inserts are steel threaded inserts commonly used in aluminum parts for added durability. Note that these are different from standard coil inserts as they have an added keyway with a tab inserted to prevent twisting under extreme load.

Key inserts are primarily used by the aerospace and military industries following the military standard of MS51835B. We offer eight thread sizes ranging from #8-32 to ½-13. For a full list, visit our threading page and click the key inserts tab.

Enhanced Machining Capabilities
We recently launched 5-axis indexed milling, which is in beta testing. This enhances the overall functionality of our CNC machines and provides customers with:

5-axis milling improves surface finishes on non-orthogonal surfaces.
  • The ability to machine non-orthogonal features like off-axis holes
  • Support for more complex geometries
  • Better finishes on non-orthogonal surfaces
  • More cost-effective machined parts

We’re constantly working on ways to make manufacturing easier and faster for our customers so please stay tuned for additional advancements in technology or material offerings.
