Having unpacked your machine and its accessories, please check the contents against the
equipment list “What’s in the box”, if there are any discrepancies, please contact us using the
procedures laid down in the catalogue. Please dispose of the packaging responsibility, much
of the material is bio-degradable. The machine and its accessories will arrive coated with
heavy corrosion preventative grease. This will need to be cleaned from the machine, its
components and accessories prior to its being set up and commissioned. Use coal oil, paraffin
or a proprietary degreaser to remove the barrier grease. Be warned, it will stain if you splash it
on clothing etc., wear overalls et al., rubber gloves are also a good idea, as is eye protection if
your cleaning process tends to be a little bit enthusiastic. After cleaning, lightly coat the
machine with a thin layer of light machine oil. N.B if you used paraffin / kerosene make sure
you apply this thin film sooner rather than lather
Please read the instruction Manual prior to using your new machine; as well as the installation
procedure, there are daily and periodic maintenance recommendations to help you keep your
machine on top line and prolong its life. Keep this instruction Manual readily accessible for
any other who may also be required to use the machine.
The BV20 required to be mounted on a rigid bed, this is to ensure stability of the machine and
to attenuate any vibration that is generated when the machine is running, (especially with
eccentric work mounted in the chuck).
The bed should be flat and set level in both planes, and at a height that enables comfortable
operation of the machine. It is not necessary to anchor the bed through to the floor, but it must
be stable enough to remain immovable during any normal forceful operations (especially
tightening) carried out whilst operating your lathe.
If you are preparing your own bed for the machine, it should be at least 870mm long by
320mm wide, you will need to drill two 14mm holes to allow for bolt fixing. Set out the centers
of the holes as follows
sizes are minimum excepting distance between centers).
From the left side of the bed (Headstock side) 170mm,150mm from the front edge of the bed.
Distance between centers 650mm; second hole again 150mmfrom front edge.
Bolt the lathe to the bed using M12 nuts, bolts and washers.
Once the lathe is mounted, remove the headstock cover plate and fill the headstock with
SAE20 oil to a level slightly above the sight glass. Do not overfill. The gearbox does not have
oil sealed bearing fitted throughout, and if you overfill oil will leak out.
The machine was fully greased and oiled before leaving the factory, but it would certainly be
prudent for you to check and re-oil all the lubrication points and lube all the beds / slides etc.,
before start up. Refer to the lubrication chart later in this manual.
Check the tension of the drive belt. If the belt is too slack, tighten by adjusting the motor
mounting plate, ensuring that you maintain co-linearity of the two pulleys.
Although the machine has been thoroughly tested at the factory, it is recommended that you
carry out a “running in” procedure to check for correct gear meshing, vibration, etc., ensure
the lathe is running “forward” (i.e. the spindle is turning towards you). Select the lowest
spindle speed i.e. 120rpm, and run for approximately 20minutes, check for vibration,
excessive noise, etc. After the 20min period, increase the speed one step at a time and run
for approximately 5 minutes in each gear. Stop the machine before changing gear. If
everything appears satisfactory, reduce the speed to one of the lower registers; manually
drive the saddle back towards the tailstock, check the saddle feed engages positively; engage
the saddle feed and drive the saddle toward the headstock, checking for smoothness of
movement, etc. Engage and disengage the saddle several times during its travel and check
that its travel pick up is smooth. If everything appears to be satisfactory, move the saddle to a
position about mid travel, MAKE SURE THE SPINDLE IS STOPPED, switch the machine into
reverse and check the machine functions equally well whilst running in reverse.
