PUT IN SERVICE Late-2016.
Acclaimed for its excellent cost to performance ratio, the A20 has
evolved as a 5-axis machine for 20 mm applications with the advantage
that it can be used with or without a guide bushing. Use
as a regular guide bushing automatic lathe when machining long,
slender workpieces or without a guide bushing for shorter parts
with minimal bar end remnants. The guide bushing can be quickly
and easily mounted and removed.
The performance of the machine has been improved too. The high
speed 10,000 rpm spindle enables optimized machining operations
on smaller diameter bar material. The machining length per chucking
is now extended to 200 mm enabling the number of re-chuckings
and therefore cycle times to be reduced when machining long
workpieces. As an option, bar material of up to 25 mm can also
be machined extending the range of workpieces.
The A20 features a new capability to switch between guide bushing
and non-guide bushing operating modes.
The machines performance, including spindle speed and machining
length per chucking, has been increased.
It is designed for ease of use and convenience with good chip
clearance for fast set-ups.
Maximum spindle speed of 10,000 rpm
The maximum speed of the front spindle
is high at 10,000 rpm enabling optimized
machining conditions on small diameter
bar material or using small diameter cutting
tools.
200 mm/1 chucking
A longer 200 mm machining stroke reduces
the need for re-chucking workpieces, which
in turn, reduces cycle time.
Support for stock material up to 25mm
With its spindle through hole diameter of
26mm, the A20 is capable of machining bar
stock up to 25mm by installing the optional
25mm size chuck device enabling a wider
range of workpieces to be produced over
the standard 20mm machine.
