Feeds Selector
This gear (A) and switch(es) (C) combination is used
to select the desired amount of feed per revolution of
the spindle and then when to engage or disengage the
function.
Important:
DO NOT
change spindle
direction until the spindle has stopped completely.
Select the feed rate with the feed rate handle (A),
matching the shift lever position to the picture on the
feed rate chart to set the desired feed rate.
There are three (3) feed rates
.0047”, .0094”, .0157”
(.11, .23, .39mm) of travel per spindle revolution.
Stop the machine when changing the feed rate. If feed
rate change is difficult, manually rotate the handwheel
(B) at the same time.
Note: The maximum spindle torque is
78lbf/ft (105Nm) and the maximum feed resistance of
the spindle is 1574lbf (7000N). Actual cutting torque
and feed resistance cannot be over these maximum
values.
The hardness of the workpiece material, cutting performance, and sharpness of the cutting tool
will influence cutting force.
Note: The work table must be clamped securely to the column when machining.
•
Securely clamp the work piece to the work table.
•
Install the desired tooling into the spindle.
•
Raise or lower the work table to suitable height and lock the column clamp. A suitable table
height will typically have the tip of the
tool approximately .5” – .75” (12 – 19mm) above the
highest point of the work piece when the quill is fully retracted. This provides a reasonably
safe clearance between the tool and the workpiece while providing the almost full quill
travel.
•
Set the depth stop to the desired depth.
•
Start the drill motor and coolant.
•
Press and hold one of the three feed clutch switches (C) and pull the quill feed handle to
lower the quill approximately .25” – .375” (6.3 – 9.5mm).
