Mori seiki sh 50 Horizontal Machining Center

SH-50 MORI SEIKI Horizontal Machining Center
A realístíc answer to today's demands Ior high quality and Iow cost

SH-50
Aperenníal problem in machíne tool design ís how to combine hígh-speed operation, efficíency and precísíon at a low cost. Today, tough productíon requírements
such as qualíty, short de]ívery tímes and competítíve prices aгe cõmmonly experienced. Consequently, the real value of machíníng centers ín customers plants must be measured
agaínst these severe standards.
Morí Seíkí can now offer the SH-50 machíníng center as a solutíon to your manufacturíng requírements. The SH-50 was conceived and developed by computer aided design (CAD),
Fíníte Element Method (FEM) and the latest technologíes to establísh machíne rígídíty that serves as the basís for hígh-speed operatíon.
The new SH-50 horízontal machiníng center provídes a large work envelope in a very compact frame. All machíne units, axís feed systems, automatic tool changer, automatíc pallet changer and spindle speeds were all desígned specifically for hígh speed
operation.
Mori Seíkí's SH-50 delívers extreme reliabílíty and an excellent cost to performance ratío. Thís machíne should provide customers with an excellent investment for many years in the
future.

Highly rígid body wíth stabílíty
Large machining capacity ín compact body
Before desígns of the SH-50 were set, Mori Seíkí utílízed the Fínite Element Method (FEM) of analyzíng machine components for optímum confíguration. Thís optímum confíguratíon provídes maximum stabílíty and support for hígh speed operatíon.
In order to specify the bed desígn, Morí Seíkí desígn engíneers símulated a heavy load at the center of the casting. From this simulation, to gíve the bed unprecedented stability, a desire which íncreased the bed thíckness to 850 mm (33.5 ín.), included ínnovatíve ríbbíng of the bed, and díctated the three
poínt support system was establíshed.
The same design techniques were applied to the column for maximum stabílíty. To enhance the column design even further, because of the fast speeds, the material was changed to a super strong ductíle cast iron for reduced weight wíth ímproved
rígídíty.
The column uses FCD450 ductile cast iron.
This yields a rigidity 1.3 times that
of Fc250 Meehanite cast iron.
Compact anatomy conceals machíníng muscle
The SH-50 has the sílhouette of a small machíne tool, but don't 1et that fool you! Axís travels are; X = 630 mm (24.8 іп.), Y= 600 mm (23.6 in.), Z= 650 mm (25.6 ín.). The table ís 500 mm (19.7 in.) square and can rotate a workpíece that is 730 mm (28.7 ín.)
in díameter.*
The SH-50 has enormous specífícatíons for a compact machíne that takes up very little floor space, which makes it perfect for today's production where space is at a premium.
With the optional 3-station turn type APC, the maximum workpiece diameter on the setup station is 610 mm (24.0 in.).

Tremendous rapíd traverse and teed rates
The SH-50 has íncreased productívíty by reducing wasted non-cut tímes (idle). This ís accomplíshed wíth rapid traverse rates of 32 m/mín (1260 ipm), feed rates of 16 m/min (630 ipm) aud speedy slíde response. An extremely rígid ball guíde is an integral part of the SH-50's speed and capabílíty.

Super effícíent and powerful spíndle drive
The spíndle ís powered by a Dírect Drive Spíndle (DDS) motor that affords; 1) great torque for cuttíng at lower speeds, 2) large horsepower for cutting at high speeds, and 3) tremendous acceleration and deceleratíon that reduces non-cut tíme. The SH-50
has 12,000 mіn-' as standard wíth 20,000 miñ ' as an
option.
The spíndle also has excellent start/stop characteristícs —started from the stopped state, the spindle reaches the top speed within a mere 1.7 seconds (high-output
specífícatíon). The quíck start feature gives a highly effícient spíndle dríve system which slashes idle time to the minimum.

Super effícient lubrícatíon system supports accuracy in machíníng
Usíng Morí Seíkí technology the uníque "Microfog" lubricatíon system was developed to direct super small (2 ji m díameter) droplets of purífíed oil dírectly on to the bearíng ba11s or ball guídes. Thís lubrícatíon system drastícally enhances the lubrícation performance whíle increasíng reliabilíty where the "aír-purge" elimínates dust.
One líter of lubricatíng oil supports machíne operatíon for approximately 1,000 hours. Thís not only reduces costs but íncreases performance.

Ceramíc Spíndle ís Standard
Space age Ceramics are used ín the spindle taper to prevent fretting, wear, chíp damage and corrosíon.*
Sínce ít ís not made of a magnetic material, the taper also has the advantage that it does not attract steel partícles and that burrs are not generated easily, which means that taper accuracy can be maíntained for long periods.
Not available for through-spindle coolant specification and 20,000 min ' specification.

Unrivaled speed and relíability with the ATC and APC
Automatíc Tool Changer
Mori Seikí ínnovatíve cam drive mechanism in the SH-50 ATC is super fast, featuring a tool-to-tool tíme of 1.3 seconds* (max. tool length: 360 mm
(14.2 in.), max. tool mass: 12 kg (26.4 1Ь.)).
Because of the cam dríve mechanism, the reliabílíty is superb.
The standard tool capacity of the ATC magazíne ís 40 Tools. Optíonally, the magazíne can be íncreased to 60, 120, or 180 tools.
`At so Hz
Automatíc Pallet Changer
The SH-50 Comes equipped wíth a two pallet APC as standard and has an optíonal three pallet system avaílable. Both types of APC handle 500 mm x 500 mm (19.7 ín. x 19.7 in.) pallets. In order to minímize idle tíme, the pallet change time ís merely 6 seconds*.
Moгі Seikí pallet system utílízes a true curvíc couplíng for accuracy and tremendous clampíng force for rigídity. The standard index íncrement ís 1°, and a rotary table (0.001 °) ís available as an option. Aі 60 Hz

Automatíc Fíxture Coupler ín Pallet
Users can select an optíonal hydraulíc/pneumatíc automatic couplíng system that ís dírected to the fíxture through the pallets. Clamp force can be adjusted to meet the cuttíng conditions without returníng pallets to the setup statíon. Machíníng rígídíty and accuracy are enhanced
as well as improving the ease of operatíon.

The SH-50 guarantees power and accuracy in a varíety of machining operations
Relíable Performance
Optimum efficiency and accuracy are always consídered in the harmony of design from Mori Seiki. The SH-50 is no exception, offering; hígh torque cutting at lower speeds, heavy duty cutting at high speeds up to 12,000 mirr', and synchronized tapping.

After cutting several typical machining patterns (geometries) on the SH-50, the results were measured using a coordinate measuring machine. Boring test data is shown at the right.

Featured as a standard specification of the SH-50 ís "feed-forward
control.* This function maintains profıle accuracy as speeds and feeds are increased whíle contouríng.

Moгі Seíkí províde a Modular productíon system that can be easIly taílored to each customer's needs. The core system would ínclude one SH-50 machíne, a pallet pool, a pallet transporter, and a setup statíon.
A second machíne ís requíred as a system controller (MORIC-A). Setup statíons, pallets and wash stations may be added as requíred. The compact design and advanced functions of the SH-50 make the system small-scale while ensuring high-level productívity.

MORIC-A* System Controller
When an unmanned system requires more than one machine, the customer can select
the MOR1C-A system controller. This controller provides the ability to respond to urgent requirements as well as having the flexibility and ease of operation you would
expect from a Mori Seiki system. The operator can easily determine the steps from
setup to machining.
