POREBA TRP 93/2M MANUAL LATHE

Technical Description

The POREBA TRP 93/2M is a robust manual engine lathe engineered for versatile turning and threading operations. Featuring a 36.5-inch swing over bed with a 78.75-inch distance between centers, this machine accommodates substantial workpieces while maintaining precision. The lathe is equipped with a 4.13-inch spindle bore and a #6 Morse taper tailstock, providing flexibility for various tooling configurations. Operating across a spindle speed range of 1 to 900 RPM with dual-speed motor capability (23/36 HP), the machine delivers consistent performance across diverse machining tasks. The longitudinal feed range spans 0.0043 to 0.249 inches per revolution, while cross feed capabilities reach 0.249 inches per revolution, enabling fine control during delicate operations and rapid stock removal. Threading capabilities encompass both metric (1-60 mm pitch) and English (0.5-30 TPI) specifications with 62 metric configurations, making it suitable for international applications. The power compound and cross slide geometry—24.75 inches swing over cross slide—facilitate efficient taper turning and complex geometries. Weighing approximately 20,500 pounds and requiring a 230-volt, three-phase, 60-hertz electrical supply, this machine is designed for shop floor integration. The 23-inch bed width and 180-inch floor space requirement accommodate standard workshop layouts. The tailstock quill features 11.75 inches of travel with a 5.125-inch diameter, supporting extended turning lengths and rigid workholding configurations ideal for production and tool-room applications.
