The KRONOS L centerless external cylindrical grinding machine is designed
for infeed and throughfeed grinding in the diameter range of 5 to 250 mm
and with a maximum infeed width up to 655 mm. The basis of the machine
is a Granitan® bed, which guarantees the KRONOS L optimum damping
characteristics and excellent thermal stability.
The machine‘s coolant discharge has also been considerably improved, in
order to guarantee optimum chip removal. Depending on the grinding task
the machine can be designed with bearing systems for conventional grinding and CBN high-speed grinding or optionally with hydrodynamic bearings for grinding and regulating wheel side.
The KRONOS L has a fixed grinding zone. This enables easy automation of
the machine – a clear advantage particularly when handling long and heavy
parts.
The machine has a modular dressing system for stationary and rotating
dressing tools. The machine can also be optionally equipped with acoustic
gap control for optimized dressing. An in-house MIKROSA software program for centerless grinding processes is used for dressing the regulating
wheel geometry during infeed and particularly during throughfeed grinding.
This significantly reduces machine setting times and guarantees an exactly
reproducible regulating wheel geometry.
