In the touch screen panel the following parameters can be setted: workhead and wheelhead speeds, some parameters of the automatic cycle (for example: dwell time at reverse and number of spark-out passes)
Accuracy
Robbi grinding machines are according to the international precision normes ISO 2433.
The table movement linearity is guaranteed by a max. deviation of 0,002 mm/mt.
Surface finish degree 0,2 Ra m.(**)
The obtainable grinding roundness is :
Grinding between centers 0,3 m (**)
Grinding with live spindle 0,4m (**)
