HEADSTOCK:

The headstock is manufactured of a single, well ribbed and proportioned casting of special stabilized cast iron.

The headstock unit design has been fulfilled so to achieve the maximum of rigidity and less vibration.

All the gears and spline shafts are made in high quality steel, hardened and ground.

The lubrication is automatic, realized by one gear pump and set of pipes.

The rotation and reverse running is obtained by a mechanical double multidisc clutch, while the spindle is stopped by mechanical ferodo brake.

The lathe is equipped as well with another electronic emergency brake for immediate stopping of the spindle in case of emergency, which is activated by the pedal or the red “Emergency“ stop buttons.

SPINDLE:

It is made of high resistance steel, casehardened, tempered and ground.

It is supported by precision, taper roller bearings SKF or FAG.

It is equipped with rear lock ring for the lash adjustment.

BED:

Heavy, large, strongly ribbed, cast iron bed with removable bridge, gives the machine great rigidity. The guideways are induction hardened and ground.

The guideways lubrication is automatic.

NORTON BOX (FEED BOX):

The norton box insure the execution of large range of automatic longitudinal and cross feeds and metric, whitworth, modular and diametral pitch threads without changing gears.

The lubrication of the norton box is automatic, realizes by a piston pump and pipes.

CARRIAGES:

Slides and carriages are well proportioned and equipped with steel tapered gibs for the lash adjustment.

APRON:

In the apron made of casting are placed all the controls for longitudinal and cross feed as well as the threading device.

It is supplied with a safety device which prevents the thread cutting and feed device acting simultaneously.

In the apron there is an automatic piston pump which lubricate the guideways of the lathe and the thread cutting nut.

On the apron is mounted also the electric motor which provides rapid longitudinal and cross travels of the carriage.

TAILSTOCK:

Strongly build with casehardened, tempered and ground quill, provided with extraction slot.

ELECTRICAL EQUIPMENT:

The electrical equipment consists of low voltage components, SCHNEIDER brand - Germany.
