Electrical system
The electrical system comprises of the following: A switch panel is mounted on the
headstock that has the start, stop and emergency stop switch. Mounted behind the
panel is the magnetic contactor. The motor is protected by an over-temperature
switch [internal to the motor].
The side access
door is protected by a switch which
cuts power to the motor should the door be opened.
Headstock spindle
The headstock spindle is the heart of the lathe, as it must run true and without any
slop or vibration. The spindle is threaded M33 x 3.5 with an internal MK2 Morse
taper. The thread is used to attach accessories such as chucks, and the Morse taper
is used for drive centers, etc. The spindle is mounted in a housing that attaches
directly to the guide bars. The spindle has a lock to stop rotation when chucks, etc.
are being attached or removed.
Guide rails
The lathe has two ground and polished steel tubes that control the longitudinal
movement on the lathe. The tailstock, copy carriage, headstock spindle housing,
fixed steady and the limit stops fit onto the guide rails.
Tailstock
The tailstock attaches to the guide rails and can be moved longitudinally. It can be
locked in any position along the guide rails. The spindle has a MK 2 Morse taper and
can be retracted or extended to suit the job.
Copy attachment
The copy attachment is a saddle that moves longitudinally along the guide rails and
moves the tool to follow the contours of a master or template that is held in a holder
located at the back of the machine. The tool can be adjusted to cut various
diameters. The template / master position is adjustable to accommodate various
sizes of work. A hand wheel that moves the saddle via a chain and sprocket controls
the longitudinal movement. A handle that moves the saddle in and out controls the
cross slide movement. The copy
saddle
travel is limited by a control knob located on
the front of the cross slide. Adjustable stops that limit the longitudinal travel of the
saddle are located on the front guide rail.
Protection screen
A screen attached to the copy saddle is provided to protect the operator from chips
that are generated when the copy attachment is being used. This is only a first
line of defense, so eye protection must always be worn when using the
lathe.
Steadies
The machine is supplied with two steadies.
One is mounted on the copy saddle and is used primarily for controlling long jobs
that are being copy-turned. The steady has rings that fit into each other. By
