What tools are needed for titanium alloy machining

Home > Knowledge > What tools are needed for titanium alloy machining

Titanium alloy is a difficult material to machine, it has high strength, high hardness, high-temperature strength, and chemical inertness. Therefore, machining titanium alloy requires the use of special tools and processing methods.

The following are some of the tools commonly used in titanium alloy machining:

1. Tungsten steel tools: Because of their high hardness, good wear resistance, and high corrosion resistance, tungsten steel is commonly used for roughing and semi-finishing titanium alloys.

PCD tools: polycrystalline cubic boron nitride (PCD) is a superhard material with extremely high hardness and thermal stability, suitable for machining high hardness and difficult-to-machine materials. In the processing of titanium alloy, PCD tools have a long life and high efficiency.

3. Drilling tools: The high hardness and strength of titanium alloys mean that high-speed rotating drills are required for drilling. A diamond-set tool consists of a diamond ball set into the tip of the drill bit, which creates a smooth orifice on the surface of the titanium alloy.

4. Coated tools: Coated tools are coated with a special coating on the surface that can increase cutting speed and life. Coated tungsten steel tools and coated silicon carbide tools are usually used for titanium alloys.

In general, wear-resistant, high hardness, high-temperature resistance, and chemically inert tools are required for machining titanium alloys. The selection of tools should be based on the specific machining process and machining requirements.
