SPECIAL INSTRUCTIONS for FREEING JAMMED ... - Sunnen

http://www.sunnen.com
GENERAL
Read these instructions through carefully to avoid
personal injury or damage to the machine.
Conditions required to create a possible hazard in
CK-10, CV-616, and SV-10 and methods for
avoiding injury or damage are as follows:
CONDITIONS
There is a certain set of conditions that can occur in
the CK-10, CV-616, and SV-10 Vertical Honing
Machines in which the machine may jam due to
improper operation. This would create a possible
hazard to the operator if he were to actuate the
Drive Arm Lift Lever.
This possible hazard can be created if the honing
tool jams tightly into the bore being honed while on
the down stroke. The honing tool could jam tight
enough to stop the stroking motion of the drive arm
which would cause the clutching belt to slip.
The operator should turn the honing machine off by
the emergency stop button when the jam-up occurs.
The overload protective device built into the
connecting Link Assembly may be in the extended
position with its overload spring compressed (see
Figure 1).
With the overload protective device in its extended
position with the machine turned off, a hazardous
condition may be present.
If the operator would attempt to lift the Drive Arm
Lift Lever just enough to unlock the over-center
lock down position of the Lift Lever, the Lever may
move or snap rapidly upward and with considerable
force, through a distance of up to seven inches of
arc travel, depending on how far the overload
protective device was extended.

CONDITION
I-CK-22A
The extended condition of the overload protective
device cannot be easily seen due to the device being
concealed behind protective guard doors (refer to
Figure 1). However, an operator could receive a
considerable jolt if the Lift Lever contacted any part
of the operator during its possible unexpected,
rapid, upward movement if the Lift Lever is
released while the overload protective device is in
its extended condition.
SHOULD JAM-UP OCCUR
If the jam-up should occur, either from improper
setup of the machine or from incorrect use of the
machine by the operator, the following steps should
be followed:
1. Immediately turn machine off with emergency
stop button.
2. Open right hand side guard door so that overload
protective device can be seen.
3. If the overload protective device is in its
extended position with its overload spring
compressed and yoke blocks separated (refer to
Figure 1), then slowly rotate Cradle Elevating
Handle counterclockwise to lower the cradle and
workpiece (see Figure 2), thereby allowing the
overload protective device to reset itself to normal
position with its two yoke blocks firmly together.
As the cradle is lowered, the drive arm and jammed
honing tool will also move downward.
Do not lower the cradle any further than that
distance necessary to permit the two yoke blocks of
the overload protective device to come together. The
movement of the two yoke blocks can be observed
through the right hand guard door opening.

4. Attempt to release the honing head or honing
tool by applying only a light to moderate retracting
force to the Feed Handwheel (see Figure 3). Retract
handwheel by turning counterclockwise when
viewed from the top. Do not apply excessive force
to the Feed Handwheel as the internal feed gears
may be damaged.
If honing tool becomes free in the bore, then
cautiously raise Drive Arm Lift Lever to lift honing
tool out of the bore and inspect tool for damage.
5. If the feed system of the honing head or honing
tool has been damaged, the operator will not be able
to free the tool by retracting the Feed Handwheel.
In this case only, after the cradle has been lowered
to release the tension of the overload device (see
Figure 4), remove the set screw that secures the
Lower Drive Tube to the Upper Drive Tube and
slowly raise the Drive Arm Lift Lever to disengage
the two drive tubes.
CAUTION
As the two drive tubes become disengaged, hold or
support the lower drive tube to keep it from falling to
one side and causing other damage.
If a CK or CV type honing head is being used,
rotate the Lower Feed Rod inside the Lower Drive
Tube three or four turns in a clockwise direction,
(viewed from top of drive tube) and gently tap
downward on the end of the Lower Feed Rod to free
the honing head from the workpiece. This action
releases the wedge from the push pins in the honing
head (may need to be repeated two or three times).
If a CV-1000 Mandrel Adapter Unit is being used,
disconnect Adapter Unit from the mandrel and then
remove mandrel from workpiece in manner required
by degree of damage found.
If a DH-Tool is being used, disconnect Adapter Unit
from the tool and then remove tool from workpiece
in manner required by degree of damage found
