Titanium CNC Machining

Titanium, whose symbol is Ti on the periodic table, is an often-utilized lightweight metal with a variety of useful properties extending from rust resistance to maintaining strength even under severe temperatures.

In its purest form, titanium contains minute amounts (less than 1%) of iron and oxygen.

Superior alloys of titanium significantly boost overall strength levels.

Offering exceptional corrosion resistance, biocompatibility, and potent strength-to-weight ratios, titanium has proven to be a prized material for resolving innumerable engineering obstacles within the medical, energy, chemical processing, defense, and aerospace sectors.

Whether crafting intricate implants, devising stronger jet engines, or designing cutting-edge prosthetics, titanium’s unique blend of qualities make it a first-choice solution for a wide array of demanding situations.

Cost-saving Design Tips

Titanium is a costly material so remember cost considerations during the design phase. Below are some tips that can reduce the expenses of working with it.

1.Material selection

Select the correct material for your application so that its high price doesn’t become excessive. For example, if a lot of material is machined away, Grade 2 titanium may be the better option as it is more machinable. Grade 5, on the other hand, is applicable for high strength at extreme temperatures.

2.Design for manufacturing

Titanium is machined as easily as high-performance steels, but it does make a few unique demands on the machinist. As such, it is critical to follow the specific DFM principles that apply to the metal. Inefficiently designed parts can slow the machining process and thus drive up costs.


When CNC machining titanium, low cutting speeds are recommended. Tool tip temperatures can be easily increased by higher cutting speeds, which can compromise tools. Other related factors include sharp tools regularly replaced at the first sign of wear, feed rates high enough to prevent work hardening and the generous use of coolant.

High speed steel (HSS) drills are excellent for Titanium so long as it is sharp, but carbide tipped drills still provide the best results and deep hole drilling. Because titanium is not a great conductor of heat, much of the heat goes into cutting tools, highlighting the need for sharp and well-maintained tools.

Poor Thermal Conductivity – cutting tools end up taking the burden of heat generation.
“Sticky” or “Gummy” Properties – can lead to problems with long “stringy” chips as well as creating built-up edge.
Low Modulus of Elasticity – leads to spring back and chatter while machining.
High Work Hardening Tendency – further increases difficulty of machining.

Titanium has very high strength and a great strength-to-weight ratio. In fact it is only 5% less strong than steel but is 40% lighter making it great for high tech industries such as aerospace, automotive and energy.
