Programming is supported by interactive graphics. The programming is thus reduced to a simple filling in of prepared masks, especially for one of the corresponding standard grinding cycles provided. Programming in ISO is possible for special grinding wheel profiles as well as for the programming of special travels of the grinding wheel on the workpiece. The machine requires a compressed air connection with filtered, dried and lubricated air at 6 bar. 5 - TACCHELLA PULSAR H 375
