11. OPTION RELATED TO SPINDLE
431
(1) Elimination of the mechanical section
Spindle orientation is enabled simply by connecting a position coder to
the spindle. The mechanical stop mechanism (stopper, pin, and so forth)
is not required for orientation.
(2) Reduced orientation time
A spindle motor connected with a spindle is used. So, orientation is
possible at high speed, regardless of the gear shift. This significantly
reduces orientation time.
(3) Simplified power magnetics sequence
The sequence consists of an orientation command, orientation
completion command, and clutch/gear signal. It does not require any
other signals. This means that sequences for orientation speed
specification and torque limit specification are not required.
(4) Improved reliability
This type of spindle orientation does not depend on mechanical
components, and therefore is not subject to mechanical damage due to
external shock. Thus, a higher level of reliability is possible.
(5) Workpiece positioning enabled
On a lathe, a workpiece can be positioned for workpiece
attachment/detachment direction alignment.
(6) Reduced number of boring steps
Positioning from the same direction as the spindle direction is possible
upon the completion of boring, so that the workpiece is not damaged by
the tool tip. In addition, a tool tip can be attached/detached in one
direction with respect to the workpiece, so that programs can be created
easily.
