When the mill is mounted to your satisfaction, proceed as follows:-
a) Locate the Head Clamp Bolt Nuts, loosen these.
b) Ensure that the bevel cup that houses the end of the head raise and lower rack is clear and
unblocked, ensure that there are no impediments to the head assembly or the tool, and swing
the head through a full 360˚. Position the head approximately over the centre line of the work
table. Raise and lower the head using the winding handle. Set the head to the required height
and reposition if necessary. Tighten the head clamp bolt nuts.
c) Check that the positive depth stop nuts are at both extremes of the gauge bar. (i.e. full
unrestricted movement).
d) Check the quill clamp is loose.
e) Check the fine feed clutch mechanism is disengaged, (the star knob is unscrewed
anticlockwise, toward the front of the mill). Check the 'coarse' feed mechanism of the quill using
the tri-handle, check that feed and movement is smooth, and the return spring counterbalance is
effective.
f) Engage the fine feed mechanism, (the star knob is screwed in clockwise), check the tri-handle
is virtually immoveable (against the gear mechanism of the fine feed), raise and lower the quill
using the fine feed control wheel handle. Check at the same time that the 'thimble' measuring
scale can be set to position and when tightened, rotates freely and remains synchronized with
the fine feed control handle (Note. The mechanism is quite 'stiff' when the machine is new, and
will ease, although the feed will always be harder against the counter balance spring than when
aided by the spring on the return). Disengage the fine feed mechanism.
NOTE: Measuring Scale fixed on ZX30M
g) Position the quill to an arbitrary position at about mid travel and tighten the quill clamp lever.
Check that the quill does not move. Release the quill clamp.
h) Set the positive depth stop nuts to 'some' position and check that they do restrict the
movement of the quill. Reset them to '0-0'. Scale for Depth Control on the ZX30M is
positioned on the front panel of the headstock. (See fig 3)
i) Ensure the longitudinal feed locks are undone. Using the drive handles wind the work table
side to side along the 'X' axis. Check you have full movement, driving the work table into the
centre stop from each side. Check at the same time that the 'thimble' measuring scale can be
set to position and when tightened, rotates freely and remains synchronized with the drive
handle. Position the work table approximately mid-way, tighten the table locks and check that
the table will not move when a 'reasonable' force is applied to the drive handles. (Note. The term
'reasonable' force is used to indicate a force you would normally use to proceed with this action,
the 'stopped/braked/locked' re-action to this force is to make you consider why the object has
not moved, and investigate. It is not to make you bunch muscles and 'heave'). Undo the locks.
j) Ensure the traverse clamps are undone. Using the drive handle, drive the work table back and
forth along the 'y' axis. Check you have full and unrestricted travel. Check at the same time that
the 'thimble' measuring scale can be set to position and when tightened, rotates freely and
remains synchronized with the control handle. Position the work table approximately mid- way.
Tighten the traverse feed locks, and check that the traverse feed will not move when a
06
'reasonable' force is applied to the drive handle. Undo the traverse clamps.
