SPH 50

KOVOSVIT SPH 50 CNC lathe machine

CNC SPH 50 lathes resolve in a productive and effectivemanner, the technology of tooling long heavy shafts, cylinders and axles.

CNC SPH 50 lathes typify the heavy version of these lathesand are recommended mainly for power machining – roughing operations.

CNC SPH 50 D lathes are designed for precise machining of form complicated parts of the shaft character.

CNC SPH 50 DS lathes are designed for precise machiningof form complicated parts of the shaft character. The machine is equipped with auxiliary counter-spindles





CNC Lathes
This cnc lathes are equipped with two independent-controlled turrets enabling machining with two tools at the same time. The tool turrets are situated on the upper bed guideways. They are oriented with tool plates to face each other in a mirrored way. The turrets are 8-position in the SPH 50, or 12-position in the SPH 50D and SPH 50 DS. They are electrically controlled and the SPH 50 D and SPH 50 DS can additionally use driven tools. The left turret enters the space above the headstock, the right one above the tailstock. Travels in the Z axis partially overlap, however, the minimum distance between the turret flange faces is 400 mm in the SPH 50, (320 mm in the SPH 50 D and SPH 50 DS). cnc lathes.

Machine basic concept

The cast bed is a box concept. The leading areas are declined by 30° from the vertical position. The upper leading area is steel, hardened (hardness 600-730 Hv) and grinded. The lower leading areas are a combination of hardened, steel and cast lines (400 HB). The bed is mounted to the cast iron base filled with forming material. On the base there are fixation areas for the base of the main motor, the covering and for the load-bearing constructions of the machine nodes. On the upper bed there are electric conductors and individual pipes that are easily accessible for the operator and other staff. The condensate and lubrication oil are collected back into the hopper for the chip conveyer by drilled channels in the bed. cnc lathes.
