TRANSCRIPT
KARGOCYLINDRICAL GRINDING
HEAVY SHAFTSEASILY GROUND
Up to six tons and several yards long – grinding shafts of this size is
a challenge that is tirelessly mastered by the grinding machines of
the Kargo series. A powerful clamping device, hydrostatic guides and
hydrostatically mounted grinding spindles guarantee the greatest
possible precision.
• Precise grinding with corundum• Designed for heavy and long workpieces• Rugged machine bed with full-protection hood• CNC control system with user-friendly interface• Post-process measurement• Recording of error messages• Display of the maintenance intervals• Compliance with all safety regulations

EQUIPMENT
• Insensitive to vibrations and low maintenance thanks to spindle mounted on hydrostatic bearings• Peripheral speed 45 m/s• Different wheelhead versions for straight plunge cut or inclined plunge cuts• Automatic compensation of grinding wheel diameter after dressing• Automatic balancing device (optional)
• Dead center• Live center (optional)• Speed programmable in a range up to 150 rpm• Offset protection through additional locking of workhead• Maximum permissible workpiece weight: 1000 to 6000 kg
• With either dead or live center• Automatic monitoring of tailstock pressure• Electromechanical actuation• Manual taper adjustment• Offset protection through additional locking of tailstock

MACHINE BED
• Use in the X and Z-axis, designed as compound slide rests• Uniform, jolt-free movement (no stick-slip effect)• Drive via servomotors with absolute encoders• High-precision positioning for precise grinding results
HYDROSTATIC GUIDE
A – Moving slide / B – Fixed guide / F – Force applied
A – Housing / B – Shaft / F – Force applied
• With gray cast iron design• High torsional rigidity and good damping behavior• Proven quality
HYDROSTATIC BEARINGS• Use in radial and axial bearings of wheelheads and workheads• Perfect rotational movement and constant centering of shaft• Vibration-damping
CONTROL SYSTEM• Choose from Fanuc or Siemens• KARGO software developed especially for the requirements of external cylindrical grinding• Easy programming, installation and operation of the machine thanks to standard ISO programming• Ergonomic machine setup through the machine control in a pivotable and movable control panel
DRESSING UNIT• Single-grain diamond or dressing fleece (standard)• Rotating dressing (optional): - Diamond profile grinding wheel or - Diamond shape roller
MEASURING
POSITIONING
• Measurement systems are adapted to the workpieces and customer specifications• In-process measurement device for measuring smooth or interrupted external diameters• Large diameter measuring range possible
• Automatic recording of reference surfaces on the clamped workpiece through bidirectional positioner• Recorded values are automatically integrated into the grinding process• Retractable integration on the wheelhead• Touch-trigger probe for precise workpiece detection
• Electronic longitudinal positioning• Steadies• Structure-borne sound sensor• Grinding spindle with dynamic balancing system• Post-process measuring system• Exhaust-air purification systems from LTA• Coolant systems
