Nigata HN-D horizontal machining certer

NIGATA MACHINE TECHNO
HN 50D/HN 63D

NIGATA'S highly regarded HN seríes machiníng center is now
redesigned as "The New Generatíon Machíne." Extensive
research in upgradíng every function of the HN models have contributed the HND to a new generation machining center to lead into the 21st century.
Both flexíblity and future expandabílity are embodíed in this powerful machine whíle downsízíng for valuable shop floor space.
NIIGATA declares that the
HN50D/HN63D will satisty all requirerments of your productíon system

Travels with Speed and
Accuracy
The slider surface ís plated with turcíte B-HP, which is self lubrícatíng and a long lífe bearíng τııateríal. The slíde ís double protected from damage by cutting chips wíth Henning wípers internally and roof shaped steel cover externally.

Precísion Pallet Positioníng Pallets are posítioned with exact
accuracy by four cone-shaped
tapered bushíngs.
Jets of air are discharged from the tapered bushíngs when a pallet is
changed to clean the bottom of the pallet, including íts tapered surfaces.
AC servo provides fast bi-directional table índexíng. The large díameter
curvíc couplíng provides extremely accurate posítíoníng of the table.
Table Index Accuracy ±3"
Pallet Positioning Repeatabllity 0.005mm {0.0002}

Y-axis double guide
The Y-axis heavy-duty box-way system employs a posítive way wíth four (4) contact surfaces to ensure straightness of motíon. The nonposítive way has three (3) contact
surfaces to maíntain rigidity and controls thermal growth.

Spindle Cooling System
To íncrease machine accuracy, the thermo-couple (temp. sensor) ís
attached to the machíne base to control the temperature of the oil
that recirculates around the spindle bearings and gear box.
This províde thermal stabílity between the spíndle and the machine base.

Oíl-aír Lubricatíon system
Thís system insured constant lubricatíon
to the spindle bearíngs preventing premature faílure versus grease packed bearíngs which requíre períodic repackíng.

Powerful Spíııdle
The spíndle-dríve system wíth 26kW (35HP) motor provídes a wíde range
of speed for hígh torque, heavy duty machining. The spíndle speed range
ís 20 to 6000mіn-1 wíth a maxіmum torque of 901N•m (665 1bs).

Spíndle Head Desígn for Maxímum Rígídíty
Large díameter (100mm {3.94"}) spindle ís supported by widely spaced super precísíon bearíngs whích maíntaín the híghest possible accuracy and rígidíty. The two range
geared spíndle-dríve system wíth 26kW (35HP) motor provides a wíde
range of speed for hígh torque, heavy duty machíníng.
The spindle head stock is a complete monoblock castíng to ínsure powerful heavy duty cutting.
Spindle face wíth pípeless coolant nozzles elimínates chíp buíld up
around coolant plumbíng and ímprove accessibility to the workpiece and fíxture.
31mm {12.2"} length spíndle snout permíts good accessíbílíty to workpiece and heavy duty cuttíng wíth shorter tooling
NIIGATA made Meehaníte castings
All structures such as base, column, saddle, spindle head and table are high quality NIIGATA made
Meehaníte castings.
Cast Meehanite construction provides superíor stabílíty and víbratíon dampeníng qualítíes.
Mono cast, T-shaped thickly ribbed bed
Mono casting of the base structure
provídes a thíck rugged bed, resultíng in hígher rígídity and maíntaíníng consistent accuracy.
Rectangular Box Ways
Hardened and ground box ways with turcíte B-hp assure heavy duty machíníng

Línear Pallet System
NIIGATA'S Línear pallet Sγstem (LPM) was developed to comply
wíth requírements to add multí- pallet pool or magazínes on exístíng
equipment. Thís desígn provides easy retro-fittíng to original standard
(2APC) equípment, namely, orígínal 2APC becomes a part of an íntegrated system.
Exístíng machíne can readíly be expanded in 2 pallet statíon íncrements.
The expansion can be added to eíther the right or left side of the
machíne.
