TopGroove™ Machining Guidelines Internal Groove Depth versus Bar Interference minimum bore diameter at maximum groove depth maximum groove depth NOTE: Internal grooving depth limits are a function of bar clearance versus bore diameters. Machining Guidelines for Back Turning/Turning/Profiling The NP-K-style TopGroove inserts were engineered specifically for back turning on small automatic lathes, but they also find applications for other light turning and profiling operations. For general applications, maximum depth of cut should not exceed 2,74mm for size 2 inserts or 3,84mm for size 3 inserts. Machining Guidelines for Using TopGroove Deep Grooving Inserts (NGD) Typically, those NGD- and NRD-style inserts with two add to C add to F cutting edges require no machine offset changes. dimension dimensioninsert However, those inserts with only one cutting edge catalogue number mm mm do require offset changes. Refer to the chart here to ensure proper offset adjustments.
