Grinding Steel without a Mask : metalworking

I'm not saying it's a great idea, but many pro metalworkers don't use respiratory protection. I used to work in a shop of 300+ toolmakers. You could tell how many weeks something had been sitting on a shelf by the amount of dust on it because that shop did a lot of grinding.. Some guys wore an N95 mask, but most guys wore nothing.

Method of producing quasispherical particles of titanium

Method includes presence of titanium oxide with the level of admixtures of at least 1.0 wt %, taken in form of ore or ore concentrate. After that performed is reaction of titanium oxide with formation of titanium oxycarbide. After that, electrolysis of titanium oxycarbide in electrolyte is carried out, with titanium oxycarbide being made as anode.

How to Safely Recover Combustible Titanium Dust .

Finer particles burn readily when their ignition point is reached, and tend to ignite the coarser particles as well. In the case of titanium, an explosion can result if ignition occurs while the particles are suspended in air as a dust cloud, since the burning extends .

Precision Grinding Metal Cutting Services | Titanium .

The precision tolerance is achieved via a grinding process or cutting operation that removes small chips (or kerf) of material. Titanium Industries has the ability to provide grinding services to tolerances on bar of .0002 (.051 mm).

Titanium Dioxide Nanoparticles (Tio2 Nanoparticles .

The amount of particles in the air (dust) can be reduced by wet grinding, which also reduces the generation of nanoparticles. Sunscreen with a sun protection factor higher than 25 can't be realised without usage of titanium dioxide.

Analysis of Burning Mechanism of Titanium Rod Grinding .

In the process of grinding titanium rods, there is a serious grinding wheel adhesion, the grinding force and the grinding temperature are very high, so the grinding burns and cracks occur simply. When the titanium rod is ground with a normal abrasive, even if the grinding depth is small, the grinding surface will be burned [.]

what is it like to grind titanium? | BladeForums

Mar 31, 2006 · Working titanium is about like stainless. It's a tough metal. When grinding, it will throw a lot of sparks and can get a little gummy if allowed to overheat. It will also turn brown or blue, but that can be polished off. It can harden if it gets very hot in a blue purple color.
