MANUAL OPERATION B-57

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.
1.
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.
2.
In center-work operation or machining using spindle 2, the tools or holders
adjacent to the tool used may interfere with the tailstock or spindle 2 in cases
such as machining a workpiece with a small machining diameter. When
mounting tools or holders, confirm that there will be no interference between the
tailstock or spindle 2 and the adjacent tools or holder. (Tailstock specifications
and Headstock 2 specifications)
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.
