3 linear axes: X, Y, Z, and 2 rotary axes: A and B.

cinematique CA7

The A axis, which supports the tool, is driven in rotation by a torque motor which allows cylindrical grinding cycles. At axis B, the active face of the grinding wheel working as close as possible to the pivoting axis of the electro-spindle, the precision linked to the indexing of this axis is optimal.


Wheel Changer


Large autonomy: 18 wheels possible in store (6 stations at the rate of 3 wheels per hub).

Easy management of grinding wheels on their hubs.

As the changer brings the hubs to the spindle, the movements required to produce the tool are not affected (compact strokes for optimum precision).

Charging time < 5s.
