Freedom concept - the better concept

The core of the CX-, - the spindle drum-, - is positioned precisely in its position by a high-precision Hirth coupling system. Together with the stringent thermo-symmetrical structure of the 

headstock, this guarantees top process reliability in all spindle positions.

With the innovative axis structure of the cross machining units used in the multi-spindle machines for the first time worldwide, Schütte has developed a concept that combines the advantages of a rigid slide construction with flexible machine configuration.

Stable, precise tool carriers and short machining times still remain important for efficient end-face grinding. The CX permits simultaneous machining on the circumference and on the front surface of the workpiece in every spindle position.

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

With its seven- or nine-spindle version, the CX 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.

The CX also offers intelligent solutions in material transfer through the machine. The requirements of the different machine versions – collet or chuck – require adaptable material workpiece discharge versions. In this sense, the modular machine design of the CX generation allows you to consider the characteristics 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).

• Integrated material feed
• Precisely positioned material pull-out from the machining area
• Variable parts discharge via chutes or conveyor belts
• Aligned, damage-free discharge into double-pallet devices during machining
• Handling of heavy chuck parts via the machine axis 
• Neutral machine interface for flexible arrangement of the parts supply and discharge

Even with their basic equipment comprising CNC compound slides for longitudinal and cross machining as well as the optional Y- and C-axes, the multi-spindle automatic lathes of the CX generation already have versatile applications. With standard auxiliary devices for special machining tasks, the application field of this series can be expanded almost without limitations. Complete machining of turned parts with milling cuts, gearing, complex extensive front and rear-side machining, top precision and reproducible quality in interaction with extremely short machining times can thus be implemented on our multi-spindle automatic lathes in the CX generation.

The CX control system makes no compromises. It works through the widest possible range of 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 CX multi-spindle automatic lathes. Parallel to these tasks, safety functions integrated in the control system protect operators and prevent damage to the machine.

With its CX series, Schütte realised the vision of a multi single-spindlle machine or multi-station machining centre for the first time. The diversity of the machining options of a multi-spindle machine is combined with the simple setup and operation of a single-spindle machine.
