POREBA TPL 90 Oil Country Lathe Hollow Spindle

Lathe in very good technical condition, has seen very little use and was not utilized for machining pipes.

Poręba TPL 90/3m lathe (also listed in market nomenclature as a variant of the TPK 90 series) is a textbook example of an Oil Country Lathe / Hollow Spindle Lathe.

This model meets all the specific criteria for machines intended for the Oil & Gas sector:
• Huge spindle bore (Big Bore): Machines in this version have a spindle bore diameter of 320 mm (approx. 12.5 inches), which allows for easy passage of thick-walled drill and casing pipes.
• Dual chuck system: The headstock construction allows for the installation of two independent lathe chucks (front and rear, typically with a diameter of 28 inches), which clamp and stabilize the pipe at both ends of the spindle.
• Optimal working range: The 3m designation defines the turning length between centers (3000 mm), which, combined with the swing over bed of 930 mm (hence the 90 in the model name), enables machining of massive pipeline elements.
• Extreme rigidity: FUM POREBA products are renowned for their monolithic, very wide, and heavy cast iron beds, which effectively dampen the significant vibrations generated during thread cutting, especially with tapered threads.

In international used machinery catalogs, this specific Poręba model is categorized directly under Oil Field Lathes.
