Boron carbide material can also be obtained by ReactivePulsed Electric Current Sintering with a tungsten boride additive [20]. Authors have obtained composites within the 1850 °C1950 °C sintering temperature range. The initial boron carbide was milled with stainless steel balls in a planetary ball mill for 10 h with high ball filling.

Ball milling is a key step in the processing of tungsten carbide parts. It ensures a good distribution of the different powders and reduces the crystallite size in the nanometer range by "mechanical alloying". The study of the influence of the rotation speed and the milling medium on the sinterability of the WCCo composite is important.

Tungsten can be cut with an abrasive cutoff wheel or ground through with the corner of a grinding wheel. Do not cut the electrodes with a wire cutter or break them by bending. This may result in unseen fractures at the cut ends, which can cause an erratic arc. Tungsten electrodes usually come with blunt ends that need to be sharpened before use.

Brazing is a good method of joining Tungsten Alloy material to itself and to other materials. To prevent oxidation, this should be done in a controlled atmosphere. Joint strength is close to that of the parent material. Brazing can alter the chemistry of the material surrounding the joint. Mechanical Joining by using bolts, pins or standard ...

How do you calculate speed and feed? Speed (RPM) = (Surface Feet per Minute x ) / Diameter of the Tool. Feed Rate = RPM x Chip Load x Number of Teeth. RPM = Of the tool or workpiece. Chip Load = The amount of material removed, per revolution per cutting edge. Number of Teeth = The number of edges, facets, or flutes.
