POREBA TR-100B1/3M MANUAL LATHES

Technical Description

The POREBA TR-100B1/3M is a precision manual engine lathe designed for heavy-duty industrial turning operations. This machine features a 39-inch swing over the bedways with a 27-inch swing over the cross slide, accommodating workpieces up to 39.5 inches in diameter with its 4-jaw chuck. The removable gap allows for 48-inch swing capacity, expanding versatility for larger components. The lathe incorporates hardened V-ways for superior accuracy and rigidity during extended production runs. With spindle speeds ranging from 5 to 500 RPM, the TR-100B1/3M delivers flexible cutting capabilities across various materials and operations. The 4.75-inch spindle bore accepts substantial tooling, while the Morse No. 6 tailstock with adjustable set-over enables precise centering and taper turning applications. Power threading functionality supports both inch and metric thread cutting, with a taper attachment and power compound system for advanced contouring work. The machine is equipped with 6-way power rapid traverse for efficient repositioning between cuts, reducing cycle times significantly. A 4-way toolpost provides quick tool changes, while integrated chip pans with coolant pump systems maintain optimal cutting conditions. The steady rest enables machining of long, slender workpieces with minimal deflection. Dual voltage electrics (220/440 volts) with 27/41 kW motor power deliver consistent performance for demanding applications. This configuration makes the TR-100B1/3M ideal for production shops requiring reliable precision turning capabilities for mid to large-scale components.
