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/Proling
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
cutting edges require no machine offset changes.
However, those inserts with only one cutting edge
do require offset changes. Refer to the chart here
to ensure proper offset adjustments.
