4) Depending on a specific situation, turn the mode
selection switch in the ATC manual OP to
“TOOL
CHANGE STEP REVERSE” (4-1), (4-3)
or
“TOOL CHANGE STEP FORWARD” (4-2)
.
4-1)
If the changer arm is stuck while trying to pull out a tool from the spindle
Turn the mode selection switch on the ATC manual OP to “
TOOL CHANGE STEP
REVERSE”
.
☞
If the machine is in the state of tool unclamping, manually perform the tool clamping
before proceeding.
▪How to confirm the state of tool unclamping: Check if the spindle emits the collet air
(in MDI or Auto mode), or check if the button indicator of Tool Unclamp on the
manual OP turns on.
4-2)
If the changer arm is stuck in the spindle after changing a tool
Turn the mode selection switch on the ATC manual OP to
“TOOL CHANGE STEP
FORWARD”
.
4-3)
If the changer arm has stopped operation irrelevantly to the spindle
Turn the mode selection switch on the ATC manual OP to “
TOOL CHANGE STEP
.
5) Repeat pressing briefly the
“START”
button on the
ATC manual OP until the main changer arm moves
to the home position where it doesn't move further.
▪In case 4-1) above, the changer arm is stuck in
the spindle for a reason while changing a tool.
Return the changer arm to the home position and
find the cause by performing the tool unclamping
manually.
If the manual tool unclamping does not work at all, gently impact on the tool to remove it
with the hammer. Then, check the tool kick distance, the state of the unclamp cylinder,
collet, and the tapering side of the spindle or tool to find out the cause of trouble and take
a necessary measure.
▪In case 4-2) above, this happens when the gripper of the changer arm is stuck in the tool.
▪In case 4-3) above, this kind of trouble shooting will be made manually while the tools are
inserted in the changer arm. Just in case of a fall of the tool, prepare a shock absorber such
as wood palette under the machine, so that it can protect the machine from a possible fall.
If
the problem persists after following the steps below, use a rubber hammer to impact on the
end of the changer arm so that the gripper can be removed. Then, pull out the changer arm
and return it to the home position. Find out the cause of trouble and take a necessary action.
(check the tool and check also if ATC is aligned properly)
