Mikrosa Kronos L dual

The Mikrosa KRONOS L dual centerless grinder is in a catagory all its own! It provides a series of processing benefits thanks to the combination of centreless grinding and grinding between centres.

The technological highlight of the KRONOS L dual is the retention of the workpiece centre in centreless grinding. As the workpiece centre is not lost, nothing is left up to chance any more. Its field of application is to be seen whenever previous or successive work steps require processing from the centres. The KRONOS L dual guarantees shorter processing times by higher stock removal performance, with the combination of grinding between centres and centreless grinding. An economical solution has been found by the machine concept on the tried and tested basis of the KRONOS L with all its benefits and features. With the KRONOS L innovative development of grinding between centres is achievable.

Features:

• Due to the combination of 2 grinding methods, the workpiece center will remain intact
• Considerably shorter processing times with high precision in comparison with grinding between centres only, as the workpiece is fully supported and therefore cannot bend.
• Reduced material handling times
• Rigid granitan machine bed ensures excellent thermal stability characteristics and superior vibration absorption
• SIEMENS Sinumerik 840 D control and Simodrive infeed technology
• Double-end supported grinding wheel and regulating wheel spindle with anti-friction bearings
• A maximum power of 133 hp allows for powerful chip-removal
• Semi-automatic grinding wheel changing enables reduction of the grinding wheel changing time to less than 15 minutes
• Motorized coolant jet adjustment in accordance with the  grinding wheel wear
