4.2
Tool-drive Motor position.
There are two optional positions for the
Tool-drive Motor. Position 1, shown in figure 1, is the position in which
the unit is shipped, and the position in which the initial setup alignment of the Mast to the machine is made.
Position 1
is the “main setup position” – and is the position for using cylindrical
mandrels. When the Drive Motor is set into position 1, the centerline of the
mandrel intersects the pivot axis of the θ motion, and remains in that
relationship even if the θ angle position is changed, or, if the X or Y linear
position is changed.
With the motor in Position 1, reciprocation is always in line with the axis of the
Tool-drive Motor shaft
– in line with the axis of the mandrel.
Position 2
is the position for using slitting and grooving tools. In Position 2,
reciprocation is always in line with the cutting plane of the grooving tool, and
remains in that relationship even if the θ angle position is changed, or if the X
or Y linear position is changed. .
In setting up Position 2, there is a procedure for aligning the cutting plane so
that it intersects pivot axis of the θ motion. It is usually a good idea to do this
alignment since it establishes a 0 Home position for that tool. Once that
alignment is made, the cutting plane intersects the pivot axis even if the θ
angle index position is changed, or if the X or Y linear position is changed.
4.2.1 MOVING MOTOR POSITION.
This view of the Motor mount Plate tells the story. Central in the photo is the
Position 1 Mounting provision. At the upper part of the photo is the Position
2 Mounting provision.
Position 1 has the familiar Ultra Tec “keyhole” mount cutout – and the Motor
Housing has the familiar cam gripping mechanism.
In removing the Motor from Position 1, loosen the cam lever, pull the Motor
Housing forward and up (see the photo).
Insertion is the reverse of that action
– insert – side back firmly against the
two dowel pins (note that there are two notches in the Motor Housing that the
pins fit into)
– and tighten the lever to lock.
For Position 2
Before setting the Drive Motor into position 2, set the
Position 2 Spacer Bar in place, engaging the two
dowel pins.
