Parts Description...
Base casting This is the stand for the milling m/c. It is a square casting with a seated flange to the
rear, which mounts the main tool post. There are four holes to each corner to be
bolted to a bench or stand. There is a dovetail slide machined to the front service of
the base, to mount the traverse slide of the work table.
Main tool post This is the column of the mill, with a dovetail slide machined on the front which the
milling head is mounted.
Rise & fall drive The rise and fall is anchored in a machined housing at the top of the tool post. It
screw has a wheel with a graduated ring (thimble), so the movement of the slide can be
measured. The wheel is connected to a rod shaft that enable the screw to be
turned, allowing the head to move up and down. Turning the handle clockwise will
raise the head and anti-clockwise to lower it.
Tilt housing The tilt housing is a turntable which is integrated in the milling head. Mounted on
assembly top of the tool post is a threaded locking pin that locks the head at 90˚ degrees
(See fig 3), turning the 10mm nut (clockwise) will drive the pin up thus unlocking
the head. On either side of the head there are two rounded nuts that clamp the tilt
assembly in position. Loosening the nuts will allow the head to pivot + 45˚ or - 45˚
degrees, using the scale and pointer on the right hand side of tilt housing.
(See figs 1 & 7)
Traverse slide The traverse slide casting mounts onto the dovetail slide of the base casting.
There is a gybe strip fitted to the left side dovetail to maintain the fit. In the front
face of the slide is a machined housing which mounts and anchors the drive shaft
for the traverse feed. Under the slide (on the base) is a threaded dog mounted in a
fixed position, through which the traverse drive shaft is threaded so as to enable the
slide to be driven back and forth. The top of the traverse slide has a female dovetail
machined into it, perpendicular to the lower dovetail. This marries with the dovetail
on the underside of the worktable. The front face of the dovetail is fitted with a gybe
strip to maintain the fit. The top of the slide also has a fixed threaded dog mounted
to it, through which the drive shaft of the worktable is threaded to allow the
worktable to be driven from side to side. In between the grubscrews and locknuts of
the gybe strip adjustor is M4 caphead bolt handles that can be driven forward to
clamp the gybe strips against the dovetails to enable the traverse and longitudinal
movements to be locked in position.
Traverse slide The traverse slide is driven using the wheel and rod handle at the front of the
control machine. Behind the boss of the handle is a graduated ring (thimble) so that the
movement of the slide can be measured. The thimble is held to the drive shaft by
friction, and can be pre-positioned to a predetermined start or stop dimension.
Work table The worktable is a machined casting 500mm long by 130mm wide. There is a
dovetail section machined in the underside to mate with the traverse slide. There
are 4 x 16mm open ended ‘T’ slots machined in the table along its length, to
facilitate the fixing of machine vices or clamps. The worktable is mounted onto the
traverse slide. The right end face of the worktable has a housing machined in it to
mount and anchor the drive shaft assembly.
Work table The Worktable slide is driven using the wheel and rod handle at each end of the
control table. Behind the boss of the handle is a graduated ring (thimble) so that the
movement of the worktable 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.
