Italian manufacturer of various industrial grinding machines. Conventional cylindrical grinders, Universal grinders, Honing machines, crankshaft grinders and internal grinding options.
Family business since 1936 originally based in Milan.
The company serves the aerospace, automotive, precision mechanics sectors and is the ideal partner in all sectors requiring a high precision grinding process.
Robbi Group has focused the efforts on product quality and has:
Mechanical construction in line with European design and enormous versatility make these machines ideal for processing components with very tight tolerances. The machine bed in normalised cast iron and the grinding wheel spindle is mounted on solid bronze bushes to ensure that our machines offer sturdiness and stability.
ROBBI CNC Universal Grinding Machines. Equipped with the latest-generation of SIEMENS 840D sl control system. The work cycle can be optimised in-process with geometrical and working parameters. The CNC version allows the operator to profile the grind wheel in relation to geometries specifically created for the type of production required.
The ROBBI CNC 60 Series are equipped with the latest-generation of SIEMENS 840D sl control system. These machines were developed in response to needs for medium-high production volumes. The work cycle can be optimised in-process with geometrical and working parameters. High precision crowning operations can be performed by equipping the machines with a third interpolated axis and a bespoke software for this processes.

The Robbi OMICRON 32 CNC Series was developed in response to needs for medium-high production volumes. The machine can be equipped with automatic measurement devices to process complex components. Equipped with the latest-generation of SIEMENS 840D sl control system.
Vertical honing allows for a better roundness. Vertical movement by recirculating ball. Ability to remove significant allowances quickly and efficiently while maintaining tight tolerances and precision. Spindle speed range gearbox with variable gear.
Horizontal honing machines LYOR are distinguished by their rigidity and power. A hydraulic cylinder controls the honing head movement. Three phase electric motor controlled by a vector inverter, servo-ventilated controlling the spindle rotation. The drive transmission is through a gear-box in which the gears are hardened and ground, projecting high torque and stock removal. Programming is very easy with the ‘touch-screen’. The visualisation of all the working data enables the operator to attend during the working cycle.
