movement that moves the tool to the right in the workpiece is referred to as +ve
'X', and movement that moves the tool to the left in the workpiece is referred to
as –ve 'X'. Where the initial position of the tooling and the worktable is designated
0,0. (Horizontal plane only).
'Y' Axis. This is the axis described by the work table as it is moved from front to back.
(Traverse) Normally movement that moves the tool to the front in the workpiece is
referred to as-ve 'Y', and movement that moves the tool to the rear in the work
piece is referred to as+ve 'Y'. Where the initial position of the tooling and the
worktable is designated 0,0. (Horizontal plane only).
'Z' Axis This is the axis described by the worktable in the vertical plane. (Not possible with
this machine). However, to establish a point in space, the co-ordinates can be
transferred to the 'tip' of the tooling, whereby, if we assume that the tool and the
worktable in their initial positions, where designated 0,0,0, (Horizontal and vertical
planes) any point above the tool tip is referred to as +ve 'Z', and any point below
the tool tip is referred to as -ve 'Z'.

Please take some time to identify the various parts of your machine so that you are
familiar with the terminology we will use to enable you to set up and operate your Mill
safely and correctly.

This is the 'Stand' for the milling m/c . It has a square seating flange to the
rear, which mounts the Main Tool Post Housing. There are 4 No.12mm holes
in the approximate corners of the base to enable it to be bolted to a bench or
the stand. There is also a dovetail slide machined on the front top surface of
the base, to mount the traverse slide of the worktable. In the front face of the
base is a machined housing which mounts and anchors the drive shaft for the
traverse feed.
tube onto which the milling head is mounted. The column is fitted with the rise
and fall rack to enable the milling head to be raised and lowered. The rise and
fall rack is held in place between a cup chamfer in the mounting housing and
a cup chamfered retaining collar and cap that slides over the top of the pillar
and is held in position by a locking screw.
a gybe strip fitted to the right side dovetail to maintain the fit. The underside
of the slide has 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 rear 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. The positive stop plate for
the worktable is also bolted to the front of the traverse slide, and there is a
threaded hole at each end of the front face into which a small Bristol handled
bolt is fitted to enable the worktable to be locked in position. There are also
two locks (small Bristol handles) on the right hand side which are tightened
to lock the traverse slide into position.
