Universal Milling Attachment. Fig. 32 shows the Universal
Milling Attachment, and as its
name implies, it is fully universal
in regard to setting the spindle.
In addition to the large amount of
work already mentioned in connection with the Vertical and Compound Vertical Attachments, this
mechanism can be used for many
othe. operations, because of the
fact that the spindle can be set at
any angle in both horizontal or
vertical planes. It is clamped to
the face of the column and the
outer end is inserted in the arbor
Fig. 32 yoke to give additional stability.

Horizontal Milling Attachment. We have mentioned the advantages to be derived from the use of vertical spindle milling attachments
on horizontal spindle
milling machines, and it
is reasonable to suppose
that to a certain extent,
similar advantages are to
be gained by the employment of a horizontal milling attachment on vertical
spindle milling machines.
An attachment of this kind
is shown in Fig. 33. It is
designed for use upon our
No. 1 Vertical Spindle
Machine, and with it such
work as cutting spiral gears,
racks, milling keyseats, etc.,
can be readily done. It is
simple in construction and
can be quickly attached to
the machine.
Circular Milling Attachments. Circular Milling Attachments provide a means of economically doing such work as milling circles,
