SPH 50 service overview

SPH 50 service focuses on long‑term operation, maintenance and spare parts support for this special CNC lathe with twin independently controlled tool turrets manufactured by KOVOSVIT MAS. Although production of the SPH 50 series has been discontinued, many machines remain in active use in industrial turning applications.

Therefore, reliable aftermarket service is essential. With proper maintenance and timely repairs, operators can continue using the SPH 50 efficiently and with stable machining accuracy.

Machine concept and twin‑turret design

The SPH 50 CNC lathe is equipped with two independently controlled tool turrets, allowing simultaneous machining with two tools. As a result, the machine significantly increases productivity by enabling parallel cutting operations on a single workpiece.

Both tool turrets are mounted on cross slides located on the upper bed guideways. They are arranged in a mirror configuration, with tool faces oriented toward each other. This layout ensures balanced cutting forces and stable machining conditions.

Tool turrets and machine versions

The SPH 50 series was available in several variants:

• SPH 50 – 8‑station electrically indexed tool turrets
• SPH 50D – 12‑station tool turrets with support for driven tools
• SPH 50DS – 12‑station tool turrets with driven tools and extended capability

Thanks to the driven‑tool option, SPH 50D and SPH 50DS machines allow additional milling and drilling operations directly on the lathe, reducing the need for secondary machines.

Axis layout and machining range

The left tool turret is designed to travel into the area above the headstock, while the right turret moves above the tailstock. The Z‑axis travel ranges of both turrets partially overlap, which allows flexible distribution of machining operations.

Minimum distance between turret flanges:

• SPH 50 – 400 mm
• SPH 50D / SPH 50DS – 320 mm

This design ensures safe and coordinated movement of both turrets even during simultaneous machining.

Typical applications of SPH 50

Thanks to its twin‑turret concept, the SPH 50 is commonly used for:

• shaft‑type components
• rotational parts machined between centers
• high‑productivity turning operations
• piece and small‑to‑medium batch production
• applications requiring reduced cycle times

Because of its productivity and stability, many manufacturers still rely on the SPH 50 as a dedicated production lathe.
