Guide for External Machining Before traversing, pull the tool back
about 0.1mm after grooving
Point ( ) (Traversing after Grooving)
(Grooving Depth Over 0.5mm: At roughing)
Grooving Depth Over 0.5mm: At roughing (Refer to Fig.1) Fig.1
Before traversing, pull the tool back about 0.1mm after grooving, instead of
traversing subsequent to grooving.
(Failure to pull the tool back before traverse cutting will result in an unbalanced
load applied on only one side of the cutting edge.)
Grooving Depth under 0.5mm: At finishing (Refer to Fig.2)
Traversing subsequent to grooving is possible because shallow groove depths
relate a small load on the cutting edge.
(Dwell-motion is not necessary.)
Point ( ) Traversing subsequent to grooving
(Grooving Depth under 0.5mm: At
When widening the groove width, apply the “Step Turning”
as shown in Fig.3. finishing)
Fig.2
G The widened groove and side walls should be finished last.
(For better chip control, ap over 0.5mm is recommended.)
Note: If the workpiece is not supported at the center,
reduce the feed rate when grooving towards center

Guide for Face Grooving
Toolholder Selection
Choose the best tool depending on the groove width.
The machining Dia. D listed in the catalog indicates the depth
of the first plunge of face grooving as shown in Fig.1.
Confirm Grooving Depth (dimension T)

Toolholder's hand is recommended so as to be Toolholder R-hand Toolholder L-hand
mounted in reverse. Fig.2
This will provide smooth chip flow and chip Insert (No Hand) Insert (No Hand)
clearance.
Traversing Tips
Traversing direction should be from the outer
diameter to the inner diameter as shown in Fig.3.
This improves chip evacuation.
