Turning Titanium Alloys
Titanium alloys have become increasingly popular for commercial and industrial use due to their impressive strength, durability and resistance to corrosion. The metals are not easily machined, however, and they require special attention when cutting and turning. The following information discusses how to turn titanium alloys and the various methods of cutting the metal.
There are a few different cutting fluids which are suitable for machining titanium alloys. Synthetic cutting fluids provide superior cooling, reduce friction and minimize wear on the cutting surfaces. In addition, they reduce the possibility of damage caused by overheating by lubricating and cooling the work surface.
A few common machining techniques are used when turning titanium alloys. The most common is single-point turning, which involves using a single cutting tool. This method is often preferred because it is able to produce accurate, smooth finishes and can be done quickly. The tool is guided by a steady hand and the cutter is pressed into the surface of the titanium alloy for the desired depth of cut.
The next method is face and contouring, which involves using a series of tools in a variety of shapes to shape the metal into a desired shape. This is a harder technique to master and is often not recommended for inexperienced operators. The technique involves using an angling cut to shape each material, with the cutting tool moving in a twisting motion.
Milling machines are also often used to machine titanium alloys. A milling machine is typically used to remove metal in the medium to high-volume amounts and is mostly used when a uniform cut is desired. The milling tool is guided along the cutting surface and can create complex geometries.
CNC machines are rapidly becoming the most popular method for machining titanium alloys. CNC machines are computer-controlled machines that can accurately and repeatably shape precisely formed parts. Similar to milling machines, CNC machines are also mostly used when a uniform cut is desired.
Titanium alloys are also often machined with honing, which is a surface finishing technique. Hones are specially designed tools that polish and smooth the surface of a workpiece and can help to dramatically increase the finish writing on titanium alloys.
Overall, titanium alloys provide significant strength and durability and are therefore an increasingly popular choice for a variety of industrial applications. They are not easily machined, however, and require special techniques and equipment to successfully turn the metal. A variety of techniques are available for machining titanium alloys, with the most common being single-point turning, face and contouring, milling, and CNC machining.
