Air connection & steps of tool change
According to the labels at the back of spindle, connect “air inlet”,
“dust removal”, “air return” and “air sealed”. Adjust the pressure as
following:
air inlet: to release the tool holder, 0.6~0.7 mpa,
dust removal: to clean the dust off the internal of rotor, 0.4~0.5 mpa
air return: to make the air cylinder return to its initial position,
0.6~0.7 mpa
air sealed: to clean the dust & chips off the external of spindle
waterway , 0.1~0.2 mpa
To change the tool, please see the steps as following:
(1) Control the valve for tool released, pressurize “air inlet” for
3~5s. At this moment, clamp inside the spindle cone will open.
(2) Control the valve of “dust removal” and pressurize it at the
pressure 0.4~0.5 mpa.
(3) Insert the tool holder into spindle cone till the cone top.
(4) Turn off the valve of “air inlet” and “dust removal” at the
same time. Discharge the air inside the cylinder through exhaust. Now the
