Aciera F2 Milling Machine
The F2 is probably the Aciera machine
least likely to be encountered with most reliable sources claiming
the number of machines imported into the UK to have been in single
figures. The production period of the F2 is very unclear since
the improrters, Adam Machine Equipment (AME), do not show the
F2 in any sales literature known to me. However, I do know of
a machine with an AME label showing that it was sold in 1961.
It appears that the F2 may have been made to special order only.
In many ways the F2 can be seen as a scaled
up version of Aciera's F1 milling machine. Spindles speeds at
between 125 and 4000 rpm are the same as those for the F1. However,
while the F1 employs the standard Schaublin W12 collet the F2
employs Schaublin's W20 item (max through capacity 14.5mm). Travels
are also significantly larger at 125mm for the X axis and 225mm
for the Y and Z axes. As with the F1 feeds are manually operated
by lever or screw. The standard table measures 150X450mm. A cabinet
mounted machine weighed in at 250 kg.
The principle departure from the F1 in
design terms consists of the inclination of the Y axis slide
away from the body of the machine by 15 degrees with all tables
and accessories having a corresponding inclination. Why Aciera
opted for this complicating design feature is somewhat of a mystery.
Like the F1 the upward movement of the table is spring balanced.
A wide range of accessories was available.
