Parts Identification and Description (Continued)
Fine feed The fine feed assembly floats around the splined gear shaft that drives the
assembly quill up and down. When the action of the fine feed mechanism is required;
pulling out ‘engage’ knob of the fine feed control meshes the gearing (you
may have to ‘joggle’ the feed handle to aid the meshing action) between the
splined shaft and the fine feed control shaft; this enables the spindle to be
driven by the fine feed control wheel with greater precision. Behind the boss
of the fine feed control wheel handle is a graduated ring (thimble) so that the
movement of the quill can be measured. The thimble is held to the drive shaft
by friction, and can be pre-positioned to establish a predetermined start or
stop dimension.
Motor control Power On LED
panel Green LED that indicates that power is available to the motor. i.e. mains is
applied, fuse is intact and the Emergency stop switch is not activated.
Fault LED (marked UNNORMAL)
Amber LED that indicates that there is a fault or an incorrect control
sequence. i.e. the chuck guard interlock has been activated or the speed
control is activated without forward or reverse direction being selected.
The Motor will not run if the fault LED is illuminated. If the safety interlock is
activated, the safety interlock will remain in force until the interlock is reset
and the start sequence re-initiated.
Fuse Cap
Access cap for the 20mm fuse cartridge (1 Amp 250V) Speed Control Knob
Round raised ridge knob connected to the circuit that controls the spindle
speed (100-1000 rpm or 100-2000 depending upon the gearbox selection).
Forward /Off/Reverse Switch
Three position switch that controls the direction of rotation of the spindle.
Forward indicates that the spindle is turning clockwise (looking down from
above, reverse, the spindle is turning anticlockwise. The centre OFF position
inhibits the spindle from turning in either direction, under motor drive.
Quill hold pocket The size of the machine precludes any ‘fancy’ locking mechanism for the
quill. There is a blind pocket on the spindle that accepts the tommy bar
supplied in the tool kit, to enable the spindle to be held in position whilst the
draw bar is loosened.
Draw bar cover A moulded plastic cover that clips into the top of the Motor Gearbox
assembly, to afford protection from the rotating top of the draw bar, when the
quill is at the top of its travel.
Draw bar This is a metal rod, threaded M10 at one end and with an 8mm squared
(unseen) shank and flange machined on the other. It is fitted through the spindle
mandrel to hold the fitted tool/tooling hard into the No2 MT taper of the
spindle shaft.
