Machining Material Ti-13V-11Cr-3Al

Material Ti-13V-11Cr-3Al is a titanium alloy with a hardness of 40 HRC and a machinability rating of 15%.

Titanium alloys such as Ti-13V-11Cr-3Al are used in mechanical components for two main reasons:

  • It has an excellent strength-to-weight ratio. On the one hand, it is almost as light as aluminum, and on the other hand, it has a higher strength than most steel alloys.
  • It has superb corrosion resistance.

The main challenges of machining Ti-13V-11Cr-3Al are:

  • Ti-13V-11Cr-3Al has very low heat conductivity. It causes heat generating from the cut to transfer mainly to the cutting tool instead of flowing to the chips and workpiece.
  • It has high flexibility, thus bending easily by the cutting forces.
  • High hardness of 40 HRC leads to premature wear.

Tip for machining Ti-13V-11Cr-3Al:

  • Use a positive cutting edge in medium/roughing operation, preferably gound with a small honing size.
  • In finish operations, use only ground inserts/tools with sharp cutting edges and minimal honing size.
  • On supper-finish applications, you can also use cutting tools that are designed for aluminum without honing.
  • On small diameter parts, on a workpiece with thin walls, or poorly clamped workpiece, be gentle with your depth of cut and feed rate to reduce the cutting force.
  • Use an insert/tool with a very hard substrate because Ti-13V-11Cr-3Al has a hardness of 40 HRC
