Carbide Preform, Cutter Preform, Carbide Cutter Preform,
Net-To-Shape Carbide Cutter Blank
It is difficult to machine the carbide blank after sintering
because of its very high hardness, lots labor, high grinding wheel
wear rate, lots machining time, and blank waste when unqualified
machining happens. In this situation, the net-to-shape carbide
preform is required. We custom the shape near your cutter before
sintering and after press or extruded, it is not big cost to do the
grinding or shaping before sintering, but can save you lots time
and money in post sintering machining.
T shape preform is the common preform style, the bigger step of the
T cutter has, the more economic to get carbide preform instead of
getting carbide rod blank.
