NUMERIKA - Cylindrical grinding machines

• Fanuc (standard) or Siemens (option)
• NUMERIKA 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 (*from platform 1500)

• Insensitive to vibrations and low maintenance thanks to spindle mounted on hydrostatic bearings
• Peripheral speed: 45 (60) m/s
• Different wheelhead versions (fixed or can be swiveled) for straight or angular plunge cuts (0° – 30°) as well as high-resolution B-axis
• Automatic compensation of grinding wheel diameter after dressing

• With fixed, revolving or universal applicable center
• Long service life due to spindle mounted in hydrostatic bearings (high-precision roller bearing optional)
• Speed programmable in a range from 20 to 1,000 rpm

• With fixed, revolving or universal applicable center
• Hydraulically controlled tailstock sleeve with adjustable axial pretension
• Precision adjustment of taper +/- 0.15 mm
• High-speed retooling with combined external and internal grinding due to CNC-controlled tailstock adjustment (optional)

• With gray cast iron design
• High torsional rigidity and good damping behavior
• Proven quality

• 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

• Single-grain diamond or dressing fleece (standard)
• Rotating dressing (optional):

1. Diamond profile grinding wheel
2. Diamond shape roller

• 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

• Use in radial and axial bearings of wheelheads and workheads
• Perfect rotational movement and constant centering of shaft
• Vibration-damping

• 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

In case of an fire, the machine interior is automatically hermetically sealed, suffocating a fire before it has a chance to spread. If required, extinguishers (CO² or water mist systems) and exhaust air purification systems can be additionally installed. A competent partner for fire protection and filtration solution solutions is LTA Lufttechnik GmbH, which also belongs to the JUNKER Group and which researches, develops and produces filtration systems for industrial air purification.
