High performance simultaneous 5 axis machining center for aluminum structures

Efficient high performance machining requires a rugged machine build-up without weakness. All technical parameters such as axis strokes, forces, torques and accelerations are set according to application requirements.
The design of the STC X series has no bottleneck reducing the maximum possible material removal rates. With its design, unmatched productivity is possible.
The STC X machine enhancement is ever ongoing. The goal is to continuously increase the customer benefits, i. e. increase productivity, increase accuracy or expand the application options.

Axis configuration

Innovative Solutions

  • Thermo-symmetrical design
  • Elements of closed welded design
  • Extremely stable and low vibration
  • Optimized using the FE method
  • High running and positioning accuracy
  • Short positioning and start-up times thanks to high acceleration

Control and System Capability 

  • NCU with the highest extension stage
  • Contour fidelity during high-speed machining through look-ahead feature and dynamic preselection
  • Drive parameter adjustment depending on the machining
  • Control cabinet with air conditioning unit

Smart operating 

Control behavior and NC path planning are developed and optimized in great detail to achieve the perfect combination of geometrical accuracy, surface quality and of course productivity. Depending on the required application, the machine can be optimally configured using five settings: roughing, pre-finishing, fast finishing, finishing and super finishing.


Monitoring

  • Process analyses and stability evaluations can be made easily with integrated sensors and evaluation routines.
  • Collision damage is significantly reduced thanks to rapid crash detection and machine stop. This is an excellent addition to Starrag’s simulation solutions to avoid expensive machine downtime.
  • The imbalance of all tools and the state of the spindle bearings are automatically monitored.
     

Measurement

  • Absolute optical measurement system for all five linear and rotary axis

Motor spindles

  • Motor spindle 30,000 rpm / 120 kW (S1) for high performance aluminum milling.
  • Oil-air lubrication directly through the outer ring (direct lubrication system)
  • Variable hydraulic bearing pretensioning
  • Vector control with constant torque up to the corner speed, thereafter constant power
  • Internal coolant supply as standard
  • Sensors for bearing temperature, thermal spindle growth with compensation and in-process vibration monitoring

 

A axis

  • Simultaneously controlled fifth CNC axis
  • Stable roller bearings on both sides
  • High positioning accuracy through a direct optical distance measuring system
  • Robust worm wheel drive
  • High driving torque
  • Hydraulic axis clamping and axis dampening
  • Even suitable for heavy-duty cutting

Table assembly / X

  • CNC rotary table as fourth simultaneous axis
  • Pallet interface with clamping arches
  • Drive with high torque and damping
  • Hydrostatic B axis clamping

 

The special workpiece geometries create specific demands on the clamping fixtures. Starrag has in-house specialists who develop individual clamping concepts to meet the specific requirements of the individual workpiece. Starrag offers the following advantages:

  • Part optimized fixturing for both efficient roughing and distortion free finishing.
  • Mechanical, pneumatic, hydraulic or vacuum clamping solutions can be implemented.
  • Media ports are accessible directly on the pallet.
  • Media clamping solutions can be included into flexible manufacturing systems.
  • The STC Series is equipped with two automatic pallet changers as standard
  • Optional hydraulic or vacuum coupling device

The STC machines are equipped with state-of-the-art tool magazines and tool changers manufactured by the Starrag Group. With a range of tool magazines from 60 to 510 tools (HSK-A63 / HSK-A63/80), it is made sure that the right solution can be selected for any application. Starrag's chain and tower magazines offer the following advantages:

  • Fast and reliable design tested in hundreds of machines.
  • Tool loading during machining process.
  • Wide variety of magazine sizes and options.
  • Dedicated solutions for oversize tools. For Starrag tool magazines features like tool breakage detection, tool coding, automated tool handling within an FMS can be implemented. Automated loading of tools into angle heads can also be realized. Regardless of the application, Starrag offers the right solution for the job.

One key factor for lowest tooling costs and the highest productivity is the right process cooling selection. The STC machines offer all state-of-theart through spindle cooling options:

  • High pressure cooling for water-based coolants or oil (pressures up to 150 bar / 2175 psi to get as close to the cutting zone as possible)
  • Through spindle air
  • Aerosol (minimum quantity lubrication)

Of course external cooling is also possible. With these options, long tool lifes and lowest overall cost can be achieved.

  • Twin swarf conveyors in the longitudinal bed
  • Generous swarf openings and angled areas
  • Integrated washing system with workpiece shower
  • Suited for either wet or dry machining
  • Absolute optical measurement system for all five linear and rotary axis

Productivity and accuracy are no longer just a question of machine and tool.
Adaptive machining of the individual workpiece is a quantum leap for many applications.
The actual shape of the workpiece is captured on the machine using Starrag’s own 5-axis measuring cycles.
The NC program can then be specifically adapted or created anew – reliably and fully automated. This technology provides advantages for a multitude of applications:

  • Non machining time («air cut») on forged blanks can be eliminated
  • The tolerances when machining with respect to pre-machined references can be tightened dramatically.
  • Thermal drift of the machine can be detected and compensated automatically.
  • Emission extractor
  • Rotating disk window
  • Conditioning unit for compressed air
  • Camera system for process monitoring
  • Handheld unit
  • Compresser temperature cooling unit for coolant conditioning
  • Increased geometric accuracy
  • Remote diagnosis
  • Warm up program
  • Tool coding
  • Any component requiring periodic service are easy accessible
  • Replacement items e.g. filters, wipers etc are easy to access
  • Machine components require service are simply to access and repair
  • Safe working areas for maintenance personal e.g. platforms and attach point are provided
  • Condition based machine monitoring to predict future component failure

Everything from simply part storage to most complex flexible manufacturing systems – even of the largest machines. The Starrag Group makes Industry 4.0 a reality. Read more
