CLASSIC MILLS

Machining highly abrasive non-ferrous materials has improved as aresult of the evolution of the KDF300 diamond coating.This coating is a pure diamond with no metallic binders. It is highlyrecommended for use in die and mold operations where graphite is a key component.The associated gains in productivity far outweigh the differences intool costs. The graph illustrates that any cost savings in labor andoverhead affects 53% of the cost to machine a part. A lower toolcost will impact only 3% of the machining costs.
