Description of features

Machine construction

The rigid construction of the Meehanite cast iron bench, with a fully ribbed tubular structure and an inclination of 30° allows to obtain in the Viper series an exceptional stability in heavy cutting conditions combined with an optimal removal and evacuation of the swarf being processed.

The reaction forces resulting from the cutting operation are minimized, obtaining a high degree of precision during machining. Both the X and Z axes are supported by suitably treated wide section flat guides, while maintaining an excellent speed of rapid movement.

Spindle head

The Viper series spindles, unparalleled in speed, rigidity and precision, are housed in a cast iron head body designed for the application of high power and relative torques.

In the realization, particular attention has been paid to the prevention of thermal deformations in order to guarantee a higher quality during the working process.

The Viper line adopts Fanuc brushless motors with double winding in order to maintain adequate power and torque at every speed and to obtain a flexible machine for the most varied uses in terms of feeds, speed and materials to be processed.

The Viper series allows to obtain an excellent surface finish and extraordinary quantities of metal removed.

The high precision, grade P4, of the angular contact bearings of the spindle line and internal bearings of suitable diameter make this model robust, precise and reliable over long periods of time.

Turret

This model is equipped with a turret of large section and proven rigidity with high rotation speed that makes this machine excellent in production machining.

The turret is equipped with 20 mm square tools and 25 mm diameter boring bars, with minimum interference between tools.

Axis translation

The axes are moved by means of preloaded THK recirculating screws Ø28 mm. for 

the X axis and Ø32 mm. for the Z axis. 

The axis motors are Fanuc brushless type of 1.0 Kw.

Tailstock

The tailstock, of the manual movement type, has a sleeve of Ø60 mm. and an MT4 connection with a stroke of 90 mm. 

Lubrication

The guides and recirculating axle screws are lubricated by means of an automatic centralised circuit. Lubrication is constantly monitored for confirmation of the actual amount of lubricant in circulation. This sophisticated monitoring system avoids any problems caused by a low or insufficient amount of lubrication pressure.

Chip evacuation

The 30° design of the bench and appropriate measures in the guards allow an optimal evacuation of the swarf created during processing, always keeping the areas relative to the axis stroke paths clean. The standard equipment of the evacuator completes the work of removing the swarf and chips from the work area.

Numerical Control

The Viper series is exclusively equipped with Fanuc CNC, i series.

In the specific case of this lathe model, the Fanuc 0iTF CNC is used.
