VOLANTINI MANUALI AVANZAMENTO TAVOLA E TESTA PORTA MOLA
- Main handwheel with division of 0.01 mm on diameter
- Micrometric handwheel with division of 0.001 on diameter
- Automatic Zero Stop
- 2 axis digital readout (SPACE 2000)
- Incremental linear encoder for micropositioning of wheelhead
- Incremental linear encoder for centesimal table movement
Within the touch screen panel the following parameters are set:
- the workhead and wheelhead speeds
- some parameters of the automatic cycle , for example: dwell time at reverse and number of spark-out passes.
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 (**)
