ROUGHING GASHER BP IV (DIN 3972) General Description The newly developed tool series for the pre-machining of outer and inner The exact positioning of inserts for each individual cutting process gear production, is the result of the optimization of negative and double- provides a vibration-free performance of the cutter. It is certainly possible positive tangential cutting edge geometry. At the root of the tooth, the to produce alternative profiles according to customers' specifications. negative insert provides the stability necessary to implement high feed When premachining pinions with a low amount of teeth, it may be more rates thus realizing a high chip removal rate. The negative insert has an economical to use a tool which complies to the involute shape with inclined bore. With the inclined position of the insert screw a higher depth protuberance inserts. Tools such as these can be supplied in special design. of thread is achieved, which stabilzes the insert pocket and thus the whole tool. The double-positive tangential insert allows for a smooth cutting process at the flank of the tooth, which reduces the axial force enormously.
