MANUAL OPERATION B-49

TAILSTOCK OPERATION (TAILSTOCK SPECIFICATION)
When machining a long workpiece, the workpiece cannot be securely supported by the chuck
alone.
Secure support of such a workpiece requires the use of the tailstock spindle.
If the workpiece is supported using the tailstock spindle, carelessly moving the tailstock
spindle in or retracting the tailstock body will leave the workpiece held by the chuck
alone. The workpiece may fall, damaging the machine, if it is held only by the chuck.
Therefore, before moving the tailstock spindle in or retracting the tailstock body, ensure
that the workpiece is held securely by a crane or other appropriate means.
WARNING
Adjust the position of the tailstock body so that the workpiece is securely
held by the tailstock spindle center when the tailstock spindle is extended.
After making this adjustment, clamp the tailstock body to the bed. It will
be possible to start memory (tape) operation when the tailstock spindle is
extended, even if the workpiece is not supported by the tailstock spindle
center. If machining is carried out while the workpiece is not supported
by the tailstock spindle center, the workpiece will fly out, causing serious
injuries or damage to the machine.
