TAP
Document Type and Number:
WIPO Patent Application WO/2008/068816
Kind Code:
A1
Abstract:
A tap that by forcibly suctioning and discharging of chips, attains not only prevention
of environmental pollution but also simplification of cleaning operation.
Tap (1) has air suction hole (5) provided with aperture (5a). Accordingly, by
air suctioning through the air suction hole (5), any chips generated at cutting
processing can be forcibly suctioned from the aperture (5a). Thus, as the chips
can be discharged without the use of cutting liquid, there can be attained prevention
of environmental pollution. Further, as not only can the chips be forcibly suctioned
from the aperture (5a) but also the chips having been suctioned from the aperture
(5a) can be discharged through the air suction hole (5), scattering of the chips
on the workpiece can be avoided to thereby attain simplification of cleaning
operation.
