Based on the specifications of the tool, the segment of PCD or CBN is accurately placed on the desired carrier, either an insert or a tool shank. The process of induction brazing joins the segment of PCD/CBN with the carrier. ACT selects C2 grade tungsten carbide steel for its wettability and hardness properties and high cobalt content. Under extreme heat – targeted on the placement of the segment – the binder of silver/copper melts and spreads into the geometric pattern of the diamond strata of PCD and the granular particles of CBN segments creating the joint between the tool carrier and the insert/tip. Once the silver/copper reaches its maximum fill, a chilling process quickly brings the temperature down to solidify the jointed materials.
The results are a precision tool that will cut accurately, is highly abrasion resistant, improves production processes and reduces overall production costs. Induction brazing, in the hands of a skilled operator, becomes an art of accuracy and precision. Highly qualified with intense training and years of experience, the artisan creates a tool of perfection.
Speed, Accuracy, Consistency
Induction brazing has the advantages of speed, accuracy and consistency. With faster heating cycles, targeted heat application and rapid cool down process; induction brazing provides better joint quality, and consistent repeatable results.
Induction brazing is targeted to very small areas with tight production tolerances. Only the segment of PCD and CBN to be jointed are heated. Heating these very small areas eliminates repeated exposure of intense heat to the fixtures and increases the life of the fixtures.
Better quality joints
When heated to an exact temperature and rapidly cooled, the filler is prevented from creeping into areas it shouldn’t. This creates clean concise joints.
Fast heating cycles
Induction heating cycles achieve exact heating and cooling temperatures quickly and allow for more parts to be processed and less heat consumption in production.
Skilled operators control the outcome of consistent quality results. Variables like time, temperature, fixturing and part positioning are controllable and repeatable.
