Milling Process of Tungsten and Other Refractory Metals

Jul 31, 2019 Discontinuous cutting operations, such as milling, are usually unsuitable for brittle and notch-sensitive materials like tungsten. When milling is required, the peripheral cutting operated on an end mill has proven to be the most efficient milling process for these materials compared to end mill slotting and other methods. When milling issues such as cracking and

Machining Tungsten Alloys How To Work With Tungsten

Tungsten Alloys use speeds and feeds similar to Gray Cast Iron. Tungsten Alloy materials becomes easier to machine as the copper content increases. The more tungsten content present the more care must be taken when machining. Carbide tools are suggested for drilling, milling, and turning Tungsten Alloys. Cutting and Sawing

Tungsten- Machining

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.
