FIMAT presents a brand new grinding machine for CV Joint cage windows.
After the new requirement of grinding cages with 4 up to 12 windows, even with different shapes on the same cage, FIMAT has designed a new grinder with 4 independent spindles (each driven by a controlled axis) and adjustable according to the type of cage to machine.
The new grinder will be able to machine cages with:
* 4 windows in 1 step (4 at once)
* 6 windows in 2 step (3 at once)
* 8 windows in 2 step (4 at once)
* 10 windows in 5 step (2 at once)
* 12 windows in 3 step (4 at once)
with cycle times ranging from 12 to 45 seconds according to the cage type.
As well as 4 spindle axes, 1 controlled axis is used for the cage vertical position and 1 rotational axis for oscillation and window pitch.
Moreover, the automation for workpart loading/unloading has been inproved by implementing a 3 axes gantry, also allowing a more compact and efficient machine layout.
Two main features of the standard machines have been kept: workpart automatic positioning and the simultaneous dressing of the 4 wheels by a motorized diamond roll.
The whole system is controlled by a Siemens 840D SL NC.
