TOOL HEAD POWER FEED
The attachment providing power vertical feed to the tool head is not standard equipment but is applied to
machines when so ordered.
The attachment consists of an adjustable cam or shoe attached to the column, and an arm and roller riding over
the cam, and connected to the vertical feed screw of the tool head
The direction of feed, up or down, is selected by
a lever mounted on the top of the ram.
The amount of feed is regulated by a screw with
a knurled knob mounted on the side of the ram. Turning
the screw downward decreases the amount of feed;
upward increases it. The amount of feed is indicated by
the graduated collar at the top of the vertical feed screw.
The actuating cam on the top of the column is
adjustable forward and backward and should be set so
that the feeding action takes place just before the end of
the return stroke of the ram.
CUTTING TOOLS
The conventional types of cutting tools are suitable for use on this machine.
Plain forged tools may be used or the inserted bit type of tool holder sets may be obtained from any of several
manufacturers of such articles.
If formed tools are to be used they, of course, must be made to suit the job in hand.
