Titanium alloys can be cut cold by conventional power hacksaws, circular saws, band saws, shears, nibblers or water jet. Hot cutting using oxyacetylene torch, plasma or laser will result in oxidation of the adjacent metal and for many applications this will require to be removed by grinding or machining before further processing is undertaken.

Slot Milling. In this process, the width of the cutter is less than the width of the workpiece: it is used to make a slot in the workpiece. Thin cutters make for thin slots. To cut the piece in two, a very thin slot can be made to go through the depth of the workpiece. Another name for this process would be "saw milling.".

During operation, though, the milling machine will press a rotating cutting tool against the stationary workpiece. As the cutting tool moves across the workpiece, it scraps off material, resulting in a smaller size. Milling can be classified as either face or peripheral, depending on the position of the cutting tool. Face milling involves a ...

Titanium Solutions. While the primary concerns when machining titanium and its alloys may shift, the methods for mitigating them remain somewhat constant. The main ideas are to avoid galling, heat generation, work hardening, and workpiece or tool deflection. Use a lot of coolant at high pressure, keep speeds down and feeds up, keep the tool in ...

Ilmenite is a titaniumiron oxide mineral with the idealized formula FeTiO. 3. It is a weakly magnetic black or steelgray solid. Ilmenite is the most important ore of titanium [5] and the main source of titanium dioxide, which is used in paints, inks, [6] fabrics, plastics, paper, sunscreen, food and cosmetics.

Properties. Titanium is a lightweight, strong and rustresistant silverwhite metal. Pure titanium is quite soft but titanium alloys are extremely strong (even stronger than steel and aluminium). Titanium has a very high melting point and is nontoxic. Titanium dioxide is one of the whitest, brightest substances known.

4. Keep it Cool. With the high heat and stringy chips generated when cutting titanium, a copious flow of clean cutting fluid is essential. Filtration to 25micron or better is a good idea for many machining operations, but is especially important with critical operations such as this. Increase the coolant concentration to 10 percent or more ...

Abstract. The chip formation in machining operations is commonly accomplished by a combination of several elements working together to complete the job. Among these components, cutting tool is the key element that serves in the front line of cutting action. Cutting action becomes a challenge when it comes to machining difficulttocut materials.

History Titanium ore was first discovered in 1791 in Cornish beach sands by an English clergyman, William Gregor. The actual identification of the oxide was made a few years later by a German chemist, Klaproth. Klaproth gave the metal constituent of this oxide the name titanium, after the Titans, the giants of Greek mythology.
