MOVING WHEELHEAD, CILYNDRICAL GRINDING MACHINESWITH ROLL GROOVING ATTACHMENT Robbi Group srl Via dell'Industria 7 37040 Veronella - VR Italia 39 0442 47700 39 0442 47966 robbi@robbispa.com www.robbispa.com

The Robbi Group offers the MSG CNC series of moving wheelhead grinding machines which are ideally suited to the grinding of carbon fibre, rubber, ceramic, composite and ferrous alloy rolls. Base • The rigid machine base structure is manufactured from normalised cast iron. A stabilised process ensures the guides will not deform over the life of the machine. Wheelhead Carriage • The wheelhead carriage is manufactured from normalised cast iron and designed to dampen any grinding vibration and provides optimal rigidity for increased surface finish. • The finished ground face of the wheelhead,...

ROBBI MSG CNC - designed for the grinding of rolls and cylinders Grooving attachment • The grooves in the rolls are performed by rotating the wheelhead electro-spindle by 90° in relation to the main grinding wheel. • The ROBBI Group designed, grooving attachment utilises electric motors that are able to cope with most types of groove. Safety • The front of the machine is equipped with a travelling guard that follows the movement of the wheelhead carriage. • Fixed guards to the rear of the machine, ensure the working area is protected. Optional Accessories: - On request. • All machine models...

Advantages of the moving wheelhead grinding machine compared to a traditional lathe The competitive advantages of a grinding machines within the machining of the roller industry includes; Grinding speed Increased amount of material removal Superior surface finish and increased part accuracy A traditional lathe, mounted with a grinding toopost is offered by some manufacturers, however, this arrangement has several flaws including, a slow and inaccurate process where todays engineers are demanding improved surface finishes and part accuracy. A Robbi moving wheelhead grinding machine can...

Roll Grooving The roll grooving attachment is mounted to the rear of the machines wheelhead. The wheelhead rotation can be manually adjusted or, on request, automatic rotation is available. Programs for almost every imaginable type of groove are provided as standard with the machine. Grinding Roll Profiles • Parallel • Concave Camber • Convex Camber • Taper • Conical • Multi Camber Robbi Group are always available to develop new grinding roll profiles. Grooving Roll Profiles • Linear • Helical Right • Helical Left

Equipment: Siemens Cnc Control ROBBI grinding machine are equipped with the latest generation of Siemens 840D sl CNC Control systems. Easy programming The Siemens 840D sl CNC control allows the machine operator to create a program, including complex programs with no ISO programming knowledge. Guided Compilation The compilation of the parameters to be ground are guided through a series of messages and icons, that explain step by step the meaning of the parameters required. The programming of the working cycles is carried out by filling in pre-defined data fields. Once the working cycle has...

Human Machine Interface (HMI) The machine operator has the ability to control the machine with an intuitive, easy to operate, and Robbi designed machine interface. This allows a faster machine set-up for the efficient grinding of roller profiles including complex grooving cycles.
