PRVOMAJSKA TNP 190 MANUAL LATHES

Technical Description

The PRVOMAJSKA TNP 190 is a conventional engine lathe designed for precision turning operations and general machining work. With a swing capacity of 7.85 inches over the bed, this machine accommodates mid-sized workpieces suitable for cylindrical turning, facing, and threading applications. The center distance of 39.29 inches provides adequate working length for producing components requiring extended turning operations between centers. Operating at 90 RPM, the lathe delivers consistent spindle speed for stable cutting performance across various material types and tool configurations. As a manual lathe, the TNP 190 requires operator control for feed rates and depth of cut, offering the flexibility and precision characteristic of conventional turning machines. The spindle bore diameter, combined with the swing and center specifications, enables the machine to accommodate standard lathe chucks and workholding fixtures common in general machine shops. The mechanical construction typical of Prvomajska equipment emphasizes durability and reliability for repetitive production and custom fabrication tasks. This lathe is suited for operations including roughing and finishing cuts on steel, cast iron, and non-ferrous materials. The manual control system allows experienced operators to adapt quickly to varying workpiece geometries and material properties. The TNP 190 represents a practical choice for shops requiring dependable turning capacity without the complexity of CNC automation, making it valuable for prototype development, small-lot production, and maintenance operations where operator judgment and adaptability are advantageous.
