G.引導用固定襯套
G.HEADLESS LINER BUSH

● 引導用固定襯套，請於插入式襯套的引導下使用。
● 引導用固定襯套請勿用於鉆孔和鉸刀的加工。
● 就引導用固定襯套和襯套承板的固定而言。
⊙普通精度的場合(一般的)因無帽緣固定式襯套，其外徑係以p6 公差製造，
固襯套承板的孔請用H7 公差，以利壓入配合。(用外徑m5 的鉸刀加工，即
可得H7 的公差。)
⊙高精度的場合:
● 襯套外徑由實測而得，而襯套承板孔徑比襯套外徑小0.004~0.006mm，裝配

時，以油壓壓床作90度垂直壓入。
● Headless liner bush is used for guide of renewable bush.

● Headless liner bush cannot be used for guide of drill or reamer.
● Information on pressing headless liner bush in the bush plate.
ôIn case of normal precision (general):
Bore a hole in bush plate at H7 in which the headless liner bush with O.D.
(D) p6 can be fitted.
(The tolerance of a hole bored by reamer with O.D. m5 is H7.)
ôIn case of requiring high precision:
● Bore in the bush plate the hole with diameter less some 0.004 ~ 0.006 than O.D.
of headless liner bush actually measured. in which the bush is straight by
oil pressure press.
