Efficiency
- Lower energy consumption through intelligent needs-based power units.
- Gantry design with vertically moving cross beam with hydraulic weight compensation.
- Fast innovative wheel type magazine with up to 243 tools with minimized footprint.
Highest rigidity and dynamics up to 5 m/s²
- Thermosymetrical construction
- 3-point support with an inherently stiff machine bed, no foundation required
- High temperature stability standard with positioning accuracy down to 15 µm
- Position accuracy down to 12 µm with accuracy pack option
- Short and continuous throat depth of milling head (no ram design)
Application Examples
Control & Software
- Automatic recognition of tool pull-in force for consistently high process stability.
- Predefined cycle for automatic lubrication, every 75h or after 20,000 tool changes.
- Detection of leakage and measuring of usage of pneumatics system.
- Efficient and timesaving lubrication without operator intervention
- High transparency by displaying the lubrication cycles and the current pull-in force.
- Data recording in combination with the optionally available Condition Analyzer for additional analyzes of air consumption and changes of the pull-in force
- Efficient use of multi-tip turning tools with more than one cutting edge on turn & mill
- Several "sister tools" on one main tool holder
- Reduction of tool change times
- Saves tool magazine space
- Vibration monitoring in the process
- Rapid shutdown in case of a crash
- Manual retraction even in swiveled machining plane
- NEW: Torque monitoring
- New: Recommended with Protection Package for CTX TC machines
- Avoiding tool breakage
- Increase in machine availability
- Damage reduction
- Process-oriented adjustment of the feed rate n relation to the table loading
- Minimization of machining time with maximization of the component quality
- NEW: Now also available for CTX TC. Ideal machining result with the highest machine dynamics*
*without consideration of feed weight
- Productive complete processing
- Cost-effective gear cutting on standard machine with standard tools
- Flexible for different gear geometries
- Quality inspection in the process
- Program creation based on blank drawings and gear data
- Optimization of workpiece orientation e.g. after heat treatment
- Interface for coordinate measuring device (Klingenberg, Leitz, Zeiss)
Turning
- Measurement and correction of the position of turning and Pivot axes (C4, C3, B)
- Sag compensation possible
- Can be used in combination with standard probes from customers (recommended Renishaw, Blum)
Milling
- Toolkit for checking and correcting the kinematic accuracy of 4- and 5-axis machine configuration
- All head variations and table axes
- Reliable re-calibration of the machine before a highly precise processing
- Continuous documentation of machine accuracy
- No rejected parts due to unknown Geometric-deviations
- Periodic recalibration of the machine with comprehensive documentation
- Highest kinematic accuracy in self-regulation
- With interpolation turning, the tool cutter follows a circular movement, where the cutter is always oriented towards the center Of the circle.
- Possible for external and internal machining
- Synchronization and tool path controlled by the cycle
- NEW: in version 2.0 complex turning contours are possible (currently only available on the DMU 50, other machine types will follow)
- Easy manufacturing of sealing surfaces where milling operation might not be possible.
- Complete component processing in one clamping possible
- Reduced investment costs for tools
- Solutions for a safe process and for the efficient use of important machining steps
- Applications: cone cleaning, tool data monitoring, safe withdrawal movement, tapping, deep hole drilling, external thread and spigot milling, internal thread and circular milling, reverse countersink cycle
- 12 stored machining strategies for stock removal, deep hole drilling, Pocket milling machines*
- Runtime optimization according to individual application
- Safe retraction after program break
- Tool data monitoring
