C-8 CHUCKING
2-2
Adjusting the Tailstock Spindle Thrust (Tailstock Specification)
With machines equipped with a tailstock, the tailstock spindle thrust must be adjusted before
chucking the workpiece.
The type and installation position of the tailstock spindle thrust adjustment handle varies
depending on the machine model.
For details, refer to the DRAWINGS published separately.
The table below shows the spindle thrusts when the gage pressure is set to the values given in the
middle column using the tailstock spindle thrust adjustment handle. Set the thrust by referring to
the table below, taking the workpiece shape and cutting conditions into consideration.
1)
Loosen the tailstock spindle thrust adjustment
handle lock nut by turning it counterclockwise.
2)
While reading the pressure gage, adjust the
tailstock spindle thrust by turning the tailstock
spindle thrust adjustment handle.
1.
CCW rotation . . . . Pressure decrease
CW rotation . . . . . Pressure increase
Exercise due care when setting the
pressure.
2.
Set the thrust force (pressure) taking the
size of the center hole in the workpiece into
consideration.
3)
Tighten the tailstock spindle thrust adjustment
handle lock nut by turning it clockwise.
