Because small pitch internal threading has small cornerr(), there is variation in the Bore Dia. which may greatly influence the tool life of an insert. In order to eliminate the variation in the Bore Dia., 0 cutting (zero cutting) should be performed as the zero pass, before the first pass in threading. he Bore Dia. is cut with the specified dimension, and the first pass of threading becomes stable. 2 Chip evacuation If machining process is continued when chips are tangled with a toolholder and other parts of the machine, it may cause damages to the insert. herefore, please ensure that there are no tangled chips in the machine by the following method. <When processing the first workpiece> et the program with the single block Keep the threading starting point 50mm~100mm away from the side of workpiece, and confirm that coolant is flushing down the chips for each pass. <When processing the second workpiece and later> Ensure that chips are not tangled; then, start the continuous run. 50 100 : td.
