Comprehensive Guide, Annealing vs Tempering: Two Different Processes. Previously obtained in this process after sintering of copper tungsten material density is low (relative density of less than 97%), especially Cu is less than 15%, the material is more severe, and thus generally can not be applied directly. This is because a negative rake provides high strength to the cutting tool, enabling it to withstand the strong cutting forces required for machining tungsten. Tapping of tungsten is quite challenging at room temperatures, and the workpiece must be heated up to 425C. When compared to other metals, tungsten has high hardness values, which leads to poor machinability. Use water or water soluble oil coolant. The high melting refractory metals contained in the alloys require high-melting electrode materials. Email: sales@chinatungsten.com Machine Tools Manuf. DBTT is the temperature above which tungsten transits into ductile behavior from an inherent brittle behavior. When sawing, use a bi-metal blade; blade pitch should be relative to the thickness of the material. The composites usually consist of 10 and 40 weight percent of copper, whereas the percentage of silver lies in the range of 20-50 percent. Therefore we recommend TUCOMET 80 and ANVILOY 170C which you can also order from us. The machining and grinding characteristics of tungsten/copper alloys are similar to those of hard grey cast iron.

Copper CNC machining technology ensures perfect repeatability, from the first part to the last, in any quantity, whether you need a single prototype component or high volume production runs with tens of thousands of pieces. However, setting the optimal parameters for your application can minimize tool wear and enhance the machining quality of tungsten. Grinding involves glazing the surface of the workpiece which can often result in high thermal stress and lead to surface cracking. Although adopting the proper tool (tungsten carbide) and ensuring good process control, can enable you to machine tungsten at room temperature, it drastically reduces tool life and results in poor surface finish. Turning speed, 300-500 surface feet per minute. Tungsten generally tends to be brittle at room temperature, making it difficult to machine, and heating it to DBTT (200C to 400C) enhances its ductile nature, improving its machinability. Grinding Use aluminum oxide or silicon carbide wheels of medium hardness. Roughing Cutting depth of .030 to .125 and .008 to .015 feed, at 200 to300 SFM.
