The resulting Secomax CBN200 CBN-tipped trapezoidal insert was designed to offer the tough- ness, wear resistance and long tool life the shop needed. In fact, the enhanced inser t reduced threading cycle time by 33 percent, Seco says. Under normal/soft part conditions, a carbide tool would generate the ACME thread in approx- imately 18 passes. With the part in the hardened state, the operation required nearly 40 passes at shallower depths of cut. That number of passes, according to Mr. Eller and Mr. Halas, was quite acceptable, considering the alternative of first machining in the soft state. Mr. Halas notes that this operation was a first for the customer and for Seco. "We had to design, produce and specify all the components, including the insert, holder and cutting parameters, specifically for this shop and this job," he says. This threading application required high rigid- ity and strength in the toolholder and machine tool performing the operation, too. Seco produced With the part in the hardened state, the threading operation for the ACME thread requires nearly 40 passes at shallower depths of cut than if the part was in the soft state.
