5-2. How To Replace Guide Sleeve
If the O.D.22mm Guide Sleeve was replaced with
the accessory Ball Bearing, the two points can be
used with the one face of Indexable Insert. It is only
limited for the mild steel machining. The Indexable
Insert life may be extremely shortened through
machining the stainless steel. Also if it has been
replaced with the accessory O.D.24mm Guide
Sleeve, you can machine the R2.
(1) Use the accessory Hex. Socket Screw key 5 to fix
the holder rotation. (Fig.9)
(2) Use the accessory Spanner 8 x 10 to loosen the
nut, and remove the O.D.22mm Guide Sleeve.
