Laser Cutting Titanium Sheet

Laser cutting of titanium high tech material for special tasks.

Laser cutting titanium sheet.

Doe and evaluation of process parameters informative nils andersson carl granberg department of materials and manufacturing technology. Co 2 lasers use an electromagnetically stimulated gas typically a mixture. Laser central can cut a variety of metals from aluminium stainless steel mild and high tensile steels to various alloys and exotic metals like titanium brass and zirconium. Hence this material is often used for specific applications in the chemical industry aerospace engineering and medical.

With the investment in our new ventis fibre laser we can now cut titanium sheet up to 8mm thick with precision and ease. The process of cutting metal at pci goes pretty simply actually for somebody who has never seen it done before but you end up just taking a standard material which for us it s very stiff types of metal put it onto a c c controlled machine which is our lasers that machine then indexes that material into it and the process. Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting. Titanium alloys are stable at different temperatures either with a hcp or a bcc crystal structure.

Pure titanium consists of hcp crystal structure at room temperature and is. 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. Laser cutting in ti 6al 4v sheet. Cnc laser cutting of titanium has traditionally been impracticle because of the reflective coefficient of titanium with the mainstream co2 cnc laser cutting systems.

The industrial use of titanium and titanium alloys is primarily based on an optimum strength weight ratio high corrosion resistance and a good biocompatibility. 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. If you d like to learn more about ablative laser cutting check out this article on micron scale manufacturing. Laser cutting metal steel titanium process of cutting metal.

The two most common types of laser cutting machines are fiber laser and co 2. In general the thicker the steel sheet the more power required to cut it and the optimum cutting rate is largely determined by the ratio of thickness to the strength of the laser.
