Medium-carbon steel is made in bar form in the cold-rolled or the normalized and annealed condition. In contrast to tungsten, metals like aluminum and copper do not have high DBTT and tend to remain ductile even at room temperatures. Rod . rake, 8-12 deg. The more tungsten content present the more care must be taken when machining. For drilling tungsten with minimal wear and a smooth surface finish, it is advised to use moderate speed with a slow feed rate. As a result, machining tungsten leads to an extremely short tool life. Tungsten machining requires specialized milling machinery, trained tungsten machining operators, and engineers with extensive tungsten machining experience. 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. While drilling tungsten, several factors must be taken into account; for instance, holes must be drilled by maintaining a gap of around one drill diameter from the edge of the workpiece. Do not use lubricant or coolant. But is it possible to machine tungsten? 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. A soft grinding wheel is preferred to minimize glazing and thereby reduce the possibility of cracking the tungsten workpiece.
