quality achievable on the new NEF universal lathes. Manufacturing
flexibility is assured by a traversable tailstock with hydraulic
quill. Other notable features are integrated safety systems and a
low space requirement. This fully enclosed machine series comes in a
space green finish; metallic optional.

The
biggest through bore spindle and a high torque capacity option
features the latest addition to a range of precision CNC lathes that
employ a massive slantbed cast iron base construction.
The
biggest through bore spindle for a Hardinge CNC lathe ever will be
launched at the forthcoming MACH 2004 exhibition.
With
a 250mm chuck as standard and a 78mm through spindle bar capacity,
the Talent 10/78
complements
the other Talent machines covering the 45 and 52mm bar range with
150 and 200mm chuck sizes respectively.
A
massive 30deg slantbed cast iron base construction is used providing
good accessibility for loading heavy parts and a

path for chips to fall into the slat type chip conveyor supplied as
standard equipment with the machine.
The
10/78
lias
a powerful 18.5kW spindle drive as standard with 404Nm torque rating
at a base speed of 437 rpm. For those really heavy cutting jobs on
big diameters there is a high torque option with 605Nm of torque at
only 292 rpm using the latest Fanuc electronic gearbox technology.
An A2- 8in spindle is mounted in a combination taper and angular
contact four bearing arrangement to produce optimum angular and
radial stiffness producing good roundness part concentricity. With a
maximum turning length of 600mm, a VDI-40 12 station turret and No 5
MT fully programmable tailstock the Talent 10/78
takes
Hardinge into the big league when it comes to turning capacity.
The
carriage and crosslide are both mounted on heavy duty 6 ball contact
linear guideway designs driven by 40mm ballscrews with a maximum
traverse rate of 30mpm. Ideal for OEM customers and sub-contractors
alike, the Talent range now covers more than 75% of all the turned
parts produced on CNC lathes by size. From small batches to
dedicated volume manufacturing the Talent has found its niche for
economical part production of turned parts. A 5.63kW 4,000 rpm
driven tooling option is available for the Talent 10/78
enabling
complete machining of many parts using С-Axis
milling, cross and end drilling and tapping in the same operation.
The fully programmable No 5 MT hydraulic tailstock has 625mm of
travel on the base and 150mm of travel on the quill for easy loading
of shaft type parts. Talent 10/78
has
Fanuc model OiTB CNC control along with the latest digital Series
spindle and axis drives and motors. A full range of optional and
additional equipment is offered for bar and chucking work, including
Renishaw automatic tool probe/tool wear monitoring system, part
probes, part catcher/conveyor, barfeeds, turret and spindle tooling.
