Cutting Titanium Sheet Metal

Since titanium alloys are a stronger and harder material they pose a unique cutting challenge best solved by carbide blades.

Cutting titanium sheet metal.

Titanium is known for its strength corrosion protection and light weight composition but because of a low melting point it is impossible to cut using traditional co2 laser technology. It s true that improvements in fiber lasers have resulted in a wider range of options for laser metal cutting including copper brass titanium and other alloys that weren t ideal for co 2. The wavelength of the optical fiber laser is 1 06μm is more easily absorbed by the metal material compared with the wavelength of co 2 which is 10 6 μm and is especially beneficial for sheet metal cutting. A secondary relief tool design in which the first positive area of the cutting edge resists forces after which the second area falls away to increase clearance accomplishes both these objectives see.

Laser cutting 1 16 stainless steel with oxygen assist gas duration. Therefore titanium is cut cold. However despite these improvements material thickness still presents a significant limitation on laser cutting. A sharp cutting edge minimizes cutting forces in titanium but the cutting edge also needs to be strong enough to resist cutting pressure.

The process of cutting titanium sheet is made even more complicated by the material s reactivity to heat. That means it s not possible to cut titanium using traditional methods without changing its chemical composition. With the investment in our new ventis fibre laser we can now cut titanium sheet up to 8mm thick with precision and ease. Laser cutting 5mm sheet metal titanium grade 5 duration.

Laser cutting titanium thick titanium materials such as plates or reinforced sheets are typically cut with co2 lasers because they have higher power capacity than other laser models. Because it is a reactive metal it changes its chemical properties when exposed to heat. Cutting titanium is not an easy task. The sheet cutting speed is 2 4 times of co 2.
