Guide for External Machining THREADING SOLID END MILLS
Point ( I ) (Turning After Grooving) Before traversing, pull the tool back about MILLING
0.004" after grooving.
1. Grooving Depths Over 0.020" : At Roughing (Fig.1)
Before traversing, pull the tool back about 0.004" after grooving, (Grooving depth over 0.020" : At roughing)
instead of traversing subsequent to grooving. Fig.1
(Failure to pull the tool back before traverse cutting will result in an
unbalanced load applied on only one side of the cutting edge.) SPARE PARTS
2. Grooving Depths Under 0.020" : At Finishing (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 ( II ) Traversing subsequent to grooving. TECHNICAL
(Grooving depth under 0.020" : At Finishing)
When widening the groove width, apply the "Step Turning" as shown in Fig.3 INDEX
Fig.2
The widened groove and side walls should be finished last.
(For better chip control, D.O.C. over 0.020" is recommended.)
Note: If the workpiece is not supported at the center, reduce the feed rate
when grooving towards center
