Okuma Serie GA/GP-FII - rettifica

Okuma GA/GP-FII Series

The cylindrical grinding machines of the GP/GA series are among the most successful in the industry and are the result of OKUMA’s experience as one of the world’s leading manufacturers.
The machine complies with EC regulations and is fitted with a protective cover.

The wide versatility of the machine’s functions makes it perfectly suited to different machining requirements.
The ‘T’ structure, with a single body for the table bed and grinding wheel head, provides high rigidity and a perfect balance of the machine has been achieved through careful design.

The newly designed spindle consists of a high-pressure hydrodynamic bearing that guarantees a MAX rotation error of 0.02µm and a rigidity of 100 Kg/µm. The hydrodynamic bearing has no contact with the shaft and is therefore not subject to deterioration.

The grinding wheel table and head slide on V-shaped, flat guides coated with anti-friction material to ensure accurate positioning and linear movement with a low coefficient of friction.

The feed of the table and the wheel-holder head is directly controlled by AC servo-motors via high-precision recirculating ball screws; a resolution of 0.0001 mm allows very high sensitivity in programming the machining operations.

The workhead (max. speed 600 rpm), suitable for grinding at fixed centres, is directly driven by an AC servo-motor; lifetime lubrication ensures high reliability and reduces maintenance to a minimum.
The particular ease of use allows the machine to reach high levels of productivity even without skilled operators. Various safety devices are installed on the machine to protect the operator from mechanical and electrical accidents.

OKUMA OSP U10G Control System for fully automatic machining cycles, the resolution of 0.0001 mm in feed on both controlled axes allows very high sensitivity in machining operations requiring high precision.
