Mikrosa KRONOS L
Heavy Duty Centerless Grinder for large workpieces



Kronos L -

The KRONOS L is designed for processing of large workpieces. It has been designed and equipped for power and volume performances. For example, we are the only manufacturer to provide the grinding spindle with a roller bearing and hydraulic clamping on both sides with a grinding wheel circumferential speed of up to 120 m/s and also a regulating wheel with bearings on both sides.

 The KRONOS L provides highly flexible possibilities of application thanks to its modular construction and design.

The semi-automatic grinding wheel changing system effectively minimises the standstill times. Therefore, small volume production can be produced without any problems on the KRONOS L.

  • 6 CNC-controlled axes enable complex processing
  • Regulating spindle with bearings on both sides
  • Automatic movement of the coolant nozzle to compensate the wear on the grinding wheel with a dressing speed of the regulating wheel of up to 700 RPM, the dressing time is short. The subsidiary times are reduced drastically in this way.
  • Grinding and regulating wheel dresser with a high degree of identical parts for more friendliness in maintenance and service
  • The grinding wheel dresser can be adapted to differing dressing methods by replacing the tool carrier.
