Pure tungsten is prone to crack when jarred or dropped. When milling it I find it very tough on sharp cornered tools, but with a bull radius (.015) instead of a sharp corner, my tool life typically increases by 3x or more. Does anyone have empirical data on coated carbide cutting tools versus non-coated carbide tools for machining tungsten?

Our tungsten alloys using cerium oxide or lanthanum oxide are somewhat easier to cut. However, the level of tool wear is still very considerable and chipping may occur.

However, the alloy possesses high strength and work hardens rapidly. Machining guidelines specific to ULTIMET ® alloy are as follows: Turning (ULTIMET® alloy) Carbide (not high speed steel) tools are recommended. Surface speed: 60-70 surface ft./min (0.30-0.35 …

Tungsten alloys are also utilized for shields and beam collimators in the Atlas Detector of the Large Hadron Collider. Our experience with extensive precision machining enables us to produce ultra-thin tungsten plates with exceptional flatness and surface finish. These plates are a key component of the detector plate assemblies used in CT scanners.

The brittle nature of tungsten is a trait shared with cast iron, another frequently machined metal. Cast iron machining provides a loose guide, and tungsten machining will use turning speeds and feed rates similar to that of cast iron. It assumes the use of commonly available C-2 tungsten carbide-tipped tools or full carbide mill ends and inserts.

of copper and copper alloys Machining copper alloys is considerably easier than machining steels or alumin-ium alloys of the same strength (see Figure 1). This is reflected in the signif-icantly lower cutting forces as shown in Figure 2. Unless specific technical requirements dictate the use of another material, free-cutting brass CuZn39Pb3

Tungsten nickel copper alloys. The non-magnetic cousin to tungsten nickel iron alloys is the tungsten nickel copper alloys. They are about as popular as nickel-iron alloys, but generally, have lower tensile strength (500-700 MPa) and ductility. They are great electrical conductors and are easy to machine despite their high mechanical strength.

Titanium Machining Guide Machining Guides • Titanium Machining Guides Machinability of Titanium Alloys Machining of titanium alloys is as demanding as the cutting of other high-temperature materials. Titanium components are machined in the forged condition and often require removal of up to 90% of the weight of the workpiece.

As long as the braze material has a melting point below the recrystallization temperature of tungsten (under 2200 o F), embrittlement can be avoided. Copper or silver alloys containing small proportions of nickel or iron are suitable for these applications. Machining and Grinding: Tungsten can be machined by turning, milling, or drilling.

I have a "tungsten" guide rod (I forgot who I bought it from) that seems to be an alloy of copper and tungsten. "Copper Tungsten" is a lesser known metal outside of the tool & die industry, where it is sometimes used to make electrodes for Electrical Discharge Machining. Copper Tungsten is VERY heavy, but not very hard at all.

Machining Nylon isn't too different from machining metals as a result of this; pretend you're machining brass. Unlike metal, though, nylon (like all thermoplastics) will deform if you hold it too tightly as it yields easily. We generally recommend Tungsten Carbide Alloy Tooling. Also, keep the part very cool and support it well.

8 tips on machining titanium and its alloys. One of the lightest metallic elements in the periodic table, titanium is also among the most important. Without this durable, high-strength material, our world today would be a far different place. Airlines would charge more for flights, houses would need painting more frequently, hip joints and ...

Tungsten-Copper- Machining. The principal Tungsten/Copper alloys contain from 2% to 45% copper by weight. The addition of copper increases the thermal conductivity of the alloy while reducing the hardness and modulus of rupture. The machining and grinding characteristics of tungsten/copper alloys are similar to those of hard grey cast iron.
