PC series Fast, exact and efficient: for your practical applications

Our automatics in the PC series are designed for material removal on geometrically sophisticated parts made of hard solid materials. The CNC multi-spindle automatics are designed to be robust, durable and technically flexible in production. 

Robust, Durable and Flexible

Machines in the PC series supply ready-to-install precision parts from small and medium batch sizes up to mass turned parts. They are used by automobile manufacturers and suppliers, in the fitting, pneumatic and hydraulic sectors and in contract manufacture.

  • high material removal rate
  • wide recesses and heavy-duty drilling operations
  • short part-production times - extremely fast, multi-axis CNC control system
  • six or eight optional workpiece spindles that can be controlled independently of one another
  • each workpiece spindle has its own longitudinal and cross slide feed units with direct position measuring system
  • rear-side machining with up to three tools
  • modular extension of CNC functions possible
  • short setup, non-production and part-production times, which can be easily programmed via 56 CNC axes

Solid machine construction is the ideal basis

All efficient performances need a foundation. For the integration of different processes, for the removal of tough materials, for speed, precision and reliable processes, this is provided by a robust machine structure. The modular and flexible Schütte concept is based on over 100 years of experience in machine tool construction.

  • robust basic structure thanks to tried-and-tested frame construction
  • base and headstock made of mineral casting guarantee high damping and thermal stability
  • optimum longitudinal slide guidance up to the material removal point by the Schütte Block
  • positioning of the spindle drum by three-piece Hirth coupling rings
  • cooling of hydraulics and cooling lubricants (option)

Modular spindle concept, cost-effective production

The effectiveness of a means of production depends essentially on how well the technologies used interact with one another. Schütte has developed a drive concept for the PC multi-spindle automatics that meets the requirements of both high-performance production as well as energy efficiency.

  • central drive with high torque 
  • individual spindle drives that can be cut in for position-specific speed selection 
  • freely programmable speed progression
  • optimisation of material removal and part-production time

Flexibility that guarantees your competitive advantage

  • spindle, feed unit and drum indexing are controlled digitally. The control quality guarantees high contour trueness during copy turning and high quality of surfaces cut with a blade
  • compact, powerful hydraulic feed drives
  • direct, high-resolution measuring system
  • interface to quick-change system SWS 400 for lathe tool
  • HSK interface for drilling tools
  • integrated handling and discharge attachment
  • damage-free and aligned discharge of workpieces

Compound slides for complex geometries

The cross slides in the PC series also make complex contours possible. Typical application fields for compound slide machining are contour turning and thread chasing. Any rotationally symmetrical contours, e.g. tapers, spherical shapes, undercuts and radius transitions can be produced with internal or external contours. 

  • also used in conjunction with driven attachments, e.g. polygon turning in the long turning procedere, milling or eccentric drilling
  • up to 15 CNC compound slides per machine type
  • CNC compound slides can be set up and retrofitted easily also for the workpiece rear side
  • CNC compound slides form the basis for attachements, stationary or driven and for the tool holder systems
  • any tyoe of outer and inner contours with simple standard cutting tools
  • hydrodynamic flat guides for the compound slides (cross)
  • hydrodynamic recessed guide for the compound slides (longitudinal)

Can be retrofitted at any time for additional tasks

Complete machining often requires the combination of different production processes. The machining of tough and high-strength materials requires perfected, flexible material removal technology. Drives, tool and auxiliary equipment are configured to fully meet the requirements of the customer. The machine can be retrofitted at any time if the application range is extended. The PC series has a comprehensive range of attachments. The machine can thus be equipped corresponding to the machining task. This includes:

  • CNC counter spindle with precision chuck
  • drill spindles (longitudinal) with HSK interface
  • drilling attachment with adjustable eccentricity from 0 mm to 26 mm and HSK interface
  • either driven via a gear set or the variable tool drive
  • polygon turning attachment with controllable drive
  • milling attachment with end mill for slot-milling
  • presettable tool system SWS 400
  • tapping or thread rolling attachment, axial or radial, and powerful drives with high torque and programmable speed curve
  • Y-axis with CNC range of functions and with up to two driven tools
  • cross drilling attachment for eccentric drilling and milling

Programming for almost every practical application

Control of 56 and more axes requires technically mature hardware and control engineering. This is particularly the case if handling and programming is not to be carried out by specialists only. The technology and operator interface "SICS 2000" is designed to make typical features, such as camshaft, cam-gear and special machining cycles available. This is supported by a flat, user-friendly operating panel. The user interface "SICS 2000" is arranged according to operating modes and operator control areas and tuned to the special requirements of a multi-spindle automatic. Interrelated processes are also grouped together in the respective menus. Programming and optimisation can be selected position-specifically according to the technological sequence and can be carried out with a high level of support for the user.

  • The hardware basis is a fast industrial PC
  • Visualisation of the movement sequence of the machine axes
  • All drive elements - electric drives, main spindle drive and hydraulic slide drives - are controlled axes
  • 56 axes (more as an option) can be programmed with "SICS 2000"
  • All machine axes are co-ordinated via a central computer
  • A Profibus system connects the control system, drive controller and control panel
  • The programming system guarantees simple and reliable programming
  • Machine and program analysis per online service
