Nigata SPN 501 Horizontal machining centers 

NIGATA MACHINE TECHNO CO., LTD.
Niigata, Japan
NIGATA, the originator of the BOX in BOX design,
Introduces the 3rd Generation SPN Series the High
SPN501/SPN701/SPN901 Horizontal Machining Cente
Buílding on a century of machíne tool design and ínnovatíon, Nigata is proud to be recognized as a leader and specíalíst ín horízontal machiníng centers. Nigata's renowned "BOX ín Box®, SPN machínes were íntroduced in 1993 and have earned the global respect as the VALUE leader.
As a complíment to Niígata's íntellígent desígn, there are a growing number of ímitators.
However, those, who try to copy or mimic Nigata, can not match the functíonality of the components whích work in harmony in
the Niigata SPN machínes. Whíle others try to "catch-up'; Niigata contínues to ínnovate ín introducing the 3 model sPN-01 seríes.
■ The casting design, the leading linear roller-guide way system, the unique reliable tool changer, and the spíndle cutting capabílity are designed to allow you to achieve your goal of
accurate parts produced in the shortest time.
Dependable, repeatable, long-term stabilíty is achieved in the statíonary column design.
■ The ínnovative castíng desígn yíelds índustry's most rigid
" T-shaped" base - enabling the use of a 3-poínt contact with your floor, and more accurate machíning.
■ The most reliable tool changer, Níígata's Synchronous Swing Motíon (SSM) ATC continues to give you years of fast dependable performance.
8000, 12000, 15000 miñ1(rpm) spindles give you the choice to fit your application.

The innovative " SPN" design begins with the " BOX in BOX®" structure,
originated by Niigata.
The statíonary "one-piece" column ís mounted on a rígid T-shaped "mono-cast" base. Thís ís the heart of machíne squareness, whích ís so crítícal in achíevíng accurate machíníng. Mount the spíndle carrying saddle to the column and the goal of practícal long-term high speed movement is realízed.
3 poínts levelling with ultra rígíd machine base

Rígídíty: Less than few micron of deflectíon of the base and column under dynamic load maintaíns squareness and allows for a 3-poínt (base to floor) ínstallation.
■ The base rígídíty is further íncreased by elímínatíng the" U " shaped cut-out found in some "center-trough" desígns.
■ The spíndle ís carríed on a ductile íron saddle (1.5 times stíffer than cast íron), whích is mounted on wide-spaced perpendícularly oriented X-axís ways.
■ Reduced mass provídes hígher ACC/DEC rates and contríbutes to lower maíntenance wíth longer life cycle.
■ Axіal thrust is always captured between the upper and lower X-ways, and no column " lean " when workíng in hígh" Y" positíons (compared to tradítíonal movíng column desígns).
■ The center of the gravíty of the mass of the spíndle and the spíndle saddle ís posítíoned dírectly above the bottom X-way, whích ís mounted in the Z-X plane.

Niígata's" BOX ín BOX®" desígn ensures long-term stabilíty of machíne accuracy
Here ís the data to proof unrivaled stabílíty of machine accuracy. It ís basícally no change of the machíne accuracy after 3 years of the machíne ínstallation.

Niigata's unique Synchronous swing Motion (SSM) Aut() t()()1 changing system....... 
For hígh speed and weight the SSM has proven to be the most relíable tool exchange mechanísın. It employs Faniic servo technology to achíeve ease of maíntenance and operator friendliness.

Self lubrication function • O
Long duration lubrícatíon desígned into the ball nut and línear roller truck means lower oØratíng cost and responsíbilíty to the environment.
■ Ultra rigid and high load type of roller guide way system

To maximize rígídity and dampeníng, roller bearíng guides are adopted on
the X, Y and Z axes.
The combined engíneeríng features, such as enhanced rígídíty of the machíne constructíon, wider span of the X and Y axes guíde ways, and the roller guíde way system meet rígorous
productíon needs.
The roller bearíngs are guíded wíth roller retainers resultíng in no rollerto-roller contact and less friction.
■ Design detaíls focuses on
operator friendliness ......... 
The operator panel ís posítíoned to the left side of operator door gívíng excellent accessíbílíty and ease of operatíon.
The manual pulse generator has XYZ axís coordínate dísplay by LCD as an
optíon

Durable way covers for high
speed posítioning......... 
It ís símple, yet effecrive. The heatresístant durable covers are ínter-connected provídíng uníform movement wíth spíndle- saddle.
•No collísíon parts. Fast and sílent
•Durable and smooth movement
•Cover ís one sheet, Mínímízes coolant and/or swarf escape
