All drives, cross slides, lubricationand cooling lines are outside themachining area

Schütte SCX | 03

Concept: FreedomMore complex workpieces in smaller batch sizes, shorter life cycles and an intenselycompetitive environment reflect present-day work processes in industrial production. The
company's scope for development is directly determined by the means of production. The
ability to react quickly and flexibly to market requirements is therefore an essential prerequisite for being and remaining competitive.
These considerations guided our engineers during the development of the new Schütte multi-spindle automatic lathes.
Everything that is not directly linked to the production of the workpiece has been eliminated from the machining area of
the SCX. Neither drive and guiding elements nor lubrication lines, cooling lines or cables can be found inside the toolingarea of the SCX. The open machining area thus provides you with the greatest possible configuration flexibility and the simplest retooling procedures.
Furthermore, the SCX from Schütte considerably extends the machining options:• On the second workpiece side through exact transfer and three additional spindles.
• In complete machining with the possibility of integrating C- and Y-axes on all positions.
A wider range of workpiece geometries than ever before is now possible in multi-spindle production.
We are proud of the result: SCX, the new CNC multi-spindle automatic lathe from Schütte.

Six spindle positions with opposed spindles complete two-side machining• Clean, freely accessible machining area
• No drives, cross slides, lubrication and cooling lines
or cables within the tooling area
• Free-falling chips• Really simple retooling and tool retrofitting• Free speed selection• Expansion of the machining range through extended
rear-side machining including C- and Y-axis

You alone determine
cycle and speed
The core of the SCX, the spindle drum, is positioned precisely in its angular position by a high-precision Hirth coupling system. Together with the purely thermosymmetrical structure of the headstock, this guarantees top process reliability inall spindle positions.
The liquid-cooled motor spindles allow you to make speed changes or to shut down spindles with high dynamics. Each spindle
has speeds that are independent of each other, thus providing
optimum cutting speeds.
The patented Schütte concept of autonomous drive
controllers without moving cables and with a minimumof slip ring contacts allows the spindle drum to cycle
through continuously and minimises wear and susceptibility to faults.

Arrange the processes
to suit your workpiece ...
... and not because the machine demands it. With world’s first innovative axis
structure of the cross machining units used in the multi-spindle machines,
Schütte has developed a concept that combines the advantages of a rigid
slide construction with a flexible machine configuration.
The cross machining units are already integrated in the standard version as cross slides and provide all
the functions of NC machining. The X-axes are guided hydrostatically via roller guides – Z-axes are designed as quills. Both are driven electromechanically. The advantages of high guidance precision andsuperior damping behaviour thus complement one another during material removal.
The cross slide units are designed as a modular system for fixed and driven tools. The internal coolant
supply is an integrated element of the tool units. This modular system can be equipped, retooled andretrofitted in a few simple steps and can be subsequently extended by auxiliary functions and axes.
Each machining unit can be equipped with a turret function for sister and follow-on tools. Further more,
every position can be equipped with a Y-axis.
All drive and guide elements, including those for the optional auxiliary devices, are outside the machining
area – a given standard throughout the SCX.

All cross machining
heads permit machining
in the X-, Z- and Y-axis• Rigid cross slide units are standard – allowing flexible
configuration with fixed and driven tools• Full CNC cross slides in all positions• Turret functions for follow-on and sister tools• Drilling and milling with C- and Y-axis• Modular system provides retooling and retrofitting options• No drives, cables, etc. within the machining area
• Excellent accessibility, free falling chips• Less wear

Two tools can be used per endworking machining unit.
Both can be used for stationary as well as driven tools,
also in combination. They can be used in all spindle
positions and can be replaced and retrofitted at any time.

Schütte SCX | 09

Show your tools who's boss –in every position
Stable, precise tool carriers and short machining times are important for efficient end-facemilling. In every spindle position, the SCX permits simultaneous machining on the circumference and on the front surface of the workpiece.
All tools for endworking machining are carried by hydrostatically mounted quills. The main material removal forces act
with a linear distribution of forces on the rigid quill body to prevent bending moments on the tool carriers.
In the same manner as cross machining, turret or cross slide units can also be used for endworking
with stationary as well as driven tools. This module system can be retrofitted for all spindle positions with identical construction and at any time.
All drive and guide elements, including the coolant and lubricant supply and those for auxiliary devices, are outside the machining area – which is standard throughout the SCX. This provides excellent accessibility and clearence. Setup and operatingprocedures can be carried out simply and safely.
A system without corners and edges guarantees free falling chips.

• Short cycle times thanks to simultaneous machining of circumference
and front surface• Absolute precision of bar feeding• Linear distribution of main material removal forces in the longitudinal
axis prevents bending moments on the tool carrier• Modular system for turret and cross slide units• Simple retooling and retrofitting in the freely accessible machining area
• Excellent accessibility• Front face machining with follow-on tools and Y-axis

Simultaneous cross and endworking machining –fast and precise

Workpiece parting off and takeoverby the opposed spindle

Two-side machining with three fully-fledged
additional spindles and up to eight tools

Schütte SCX | 11

Discover the other side
With its seven- or nine-spindle version, the SCX opens up a completely new dimension
in machining of the workpiece rear side. Complex workpieces can now be manufactured completely in a single operation without leaving the machine.
After machining the first side, the workpiece is parted off and transferred with the opposed spindle (spindle
position 7) to a new machining area. Here, two fully-fledged machining units complete the workpiece in two
further cycles on two opposed spindles (spindle position 8 and 9). As on the headstock side, they are provided
with all functions, for example, C- and Y-axis, polygon turning, or turret.
After the precise takeover of the workpiece by an opposed spindle during part-off, it remains firmly clamped ina collet or jaw chuck for the machining cycles. The HSK quick-change interface, which has been tried and tested
for decades, is used to forward the workpiece with a high degree of accuracy in concentricity and positioning.
This also applies to machining of the second side: the material removal area remains free and cleared because
all drives are located outside the machining area.

• Accurately positioned transfer of the workpiece using the tried andtested HSK quick-change interface• Machining of the workpiece rear side in three additional fully-fledged spindles• Workpiece is firmly clamped and forwarded in its clamping device without
loss of accuracy• All functions (C- and Y-axis, polygon turning, turret) are also available
for the second side
• Complete machining of the workpieces• The machining area remains open and easily accessible

Your workpiece determines
the type of clamping – collet
or chuck
Irrespective of the selected basic material – bars, bar sections, cast or forging blanks –the flexibility of the SCX is also reflected in its various clamping concepts. The freely
selectable version as chuck, bar or magazine machine makes adaptation of the machine
to diverse production concepts possible.
The chuck clamping system available on the SCX-46 permits machining of moulding blanks with diameters up to
130 mm. Needless to say this includes an option of end-face milling and rear-side machining (with opposed spindle
and 2 additional spindles for machining the second side).
The magazine machine with collet clamping completes the machine range. Positive opening, spring stop in the main
spindle for inserting the blank and, optionally, active ejection of the machined workpiece onto the discharge chute or
into the opposed spindle are only a few of the features that characterise material clamping on the SCX.
Tried and tested new material transfer concepts – amongst others the Schütte feed, bar feeding via the loading
magazine, pre-drawing from the machining area via the cross or longitudinal positions and the innovative material
supply and discharge via the cross slide in position VI – supplement the SCX to a multifunctional production system for highly complex workpieces with varied designs.

• Flexible production of bars, bar sections, forging or cast blanks• Material clamping in collet or chuck on the main and opposed spindle• Maximum machinable part diameter 46 mm (collet clamping) or 130 mm(chuck clamping)• Full rear-side function in every machine version• Multifaceted material transfer versions from raw material provision tofinished part discharge• Spring stop / active ejection of magazine parts

The SCX is designed for flexible use – irrespective of whether
you are processing bar material or prefabricated blanks

Machine-integrated workpiecehandling by the pallet system –an intelligent concept for damagefree and aligned discharge of theworkpieces. Automatic sorting of
inspection parts and in-process
measurement is also possible

Schütte SCX | 15

From raw material
to the finished part –workpiece transfer
The SCX offers intelligent solutions in material transfer by the machine. The requirements ofthe different machine versions – collet or chuck – necessitate adaptable material workpiecedischarge versions. In this sense, the modular machine design of the SCX generation allows
you to make allowance for the characteristic differences of the raw material (e.g. bars, bar
sections, forging or cast blanks), workpiece weight and size as well as material ejection (random, aligned or damage-free).
The SCX generation offers – apart from the classic feed versions by the bar loader – a machine-integrated bar
infeed. Optionally, the material can be advanced inside the spindle or can be pulled forward from the machining
area with high positioning accuracy. The finished parts are ejected either by means of chutes or conveyor
belts to the front or rear side of the machine. With increased demands on the discharge quality, a machineintegrated workpiece handling system permits damage-free and aligned depositing in a double-pallet
device. The pallets can be replaced during machining in automatic mode.
For handling magazine and chuck parts – particularly with increased workpiece weight –the machine program includes parts handling on the basis of the cross slide unit position
VI. Workpiece transfer in the machine is based on an integrated hood interface via themachine axis in position VI, whereas the external part infeed and discharge to up to hood interface can be arranged according to the customer's wishes. A wide variety of solutions from pipe infeed and chutes throughconveyor belts up to robots can be configured.

• Integrated material feed
• Precisely positioned pre-drawing of material from the machining area
• Variable parts discharge via chutes or conveyor belts• Aligned, damage-free placement into double-pallet devices duringmachining• Handling of heavy chuck parts via the machine axis position VI• Neutral machine interface for flexible arrangement of the parts infeed
and discharge

One system –so you remain flexible
Even with the modular tool system of the SCX, we integrated the concept of freedom. Tool units with one or several stationary or driven
tools, or even a combination of both, can be used both for endworking and cross machining.
The standard tool units include devices for drilling, contour milling and hobbing, spherical andpolygon turning (cross) as well as cross slides (endworking) for driven and stationary tools. Essentially important: all units can be used independently from one another in every spindle position.
Currently marketed, standardised quick-change interfaces permit fast and convenient changing
of the tools. The possibility of tool presetting outside the machine allows you to shorten retooling times even more. Internal coolant supply up to the tool cutter also makes its contribution inthis regard. The new SCX concept considerably widens your production time frame.

• Modular tool carrier system• Integrated coolant supply (suitable for high pressure)• Precise quick-change interfaces facilitate thepresetting• Compact tool carriers guarantee free falling chips andeasy access.
• Top accuracy of repeatability during tool change• Simple and convenient setup
Ease of physical and visual access for assembly and disassembly of the tool heads

The modular tool system makes your application options
flexible and reduces idle machine time

Additional equipment
extends range of applications
Already with its basic equipment – comprising CNC cross slides from endworking and crossas well as Y- and C-axes – the SCX multi-spindle automatic lathes already have versatile applications. With standard additional devices for special machining tasks, the range of the application field of this series can be expanded almost without limitations. Complete machining of turned parts with milling cuts, toothing etc., complex extensive front and rear-side
machining, top precision and repeatable quality in interaction with extremely short machining times can thus be implemented on our multi-spindle automatic lathes in the SCX
generation.
The machining modules for endworking, cross and/or rear-side machining for turning, drilling, mill cutting, tooth grinding, thread cutting, polygon turning or form shaping can beused within the working area assigned to them (endworking, cross) in all spindle
positions and can also be interchanged according to your specific process requirements.
The application example on the left shows a spherical turning attachment. The circular path is executed by a single pivot movementof the machining unit. Instead of a spherical turning attachment, a roller
burnishing tool can also be used. The ball diameter can be programmed and corrected by the CNC.

Controlled diversity –operation and configuration
The SCX control system makes no compromises. It works through the widest possible rangeof machining programs – reliably, precisely and in extremely short cycle times. Before machining starts, it supports users with intuitive dialogue, templates and information on tooling, setting work, operation, maintenance and service of the SCX multi-spindle automatic
lathes. Parallel to these tasks, safety functions integrated in the control system protect operators and prevent damage to the machine.
Configuration and NC programming is simplified by SICS. SICS software is used both on a work
preparation PC as well as on the machine control panel. The operator selects tooling for setup from a clearly arranged menue and parameterises it. Linked to the NC program, the setup is then loaded automatically. SICS thus controls, among other things, the basic movements of the tool heads, the part orientation plan for palletising and the axis configurationof the machining positions.
NC programming supports SICS by adopting the previously defined machine and tooling
setups. The programmer is offered optimised program and function templates in the individual positions for the set-up equipment. They can then be used by the NC programmer
to create an optimised NC program, with minimal operator input covering the entire frommaterial feed to machining and parts discharge.

• Fast control for short cycle times• Precise synchronisation and dialogue-guided configuration of all positions• Fully programable load/unload process optimazation• SICS integrated for work station programming and at machine• Clearly arranged management of the tool heads• Loading of setup data with the NC program• NC programming with graphical support• Equipment-specific NC templates as programming aid

The Schütte programming philosophy assures reliable

One concept –you select your version
With its SCX series, Schütte re-defines the vision of a “multi single-spindle machine”: the diversity of the machining options of a multi spindle machine combined with the simple setup and operation of a single spindle machine.
The SCX offers different versions for workpieces of varying complexity. Six main spindles andan opposed spindle for workpieces can be manufactured almost completely from the first
workpiece side. Plus the 9-spindle machine for workpieces that also have to be extensively machined on the opposite workpiece side – economic and complete.
