POREBA TR135B2/5M MANUAL LATHES

Technical Description

The POREBA TR135B2/5M is a heavy-duty manual centre lathe engineered for industrial turning operations on large workpieces. It features a 53-inch swing over bedways with a 17-foot distance between centres, enabling extended turning lengths of up to 6,000 mm. The lathe accommodates a maximum turning diameter of 1,350 mm over the bed and 1,000 mm over the cross slide, while the removable gap insert allows for a 64-inch swing capacity. The spindle operates across a range of 5 to 500 RPM with a 4.75-inch through-hole bore, supporting spindle mount MK 6. Equipped with a 39.5-inch diameter 4-jaw chuck, the lathe delivers precise workholding for demanding applications. The power compound enables efficient taper turning operations, while the 6-way power rapid traverse system enhances productivity during tool positioning. An integrated 28-inch diameter steady rest provides critical support for slender workpieces, reducing deflection and improving surface finish. The machine incorporates a standard 4-way tool post for versatile tooling configurations. With dual-gear power transmission delivering 27 kW in first gear and 41 kW in second gear, the lathe provides substantial cutting force across various materials. Electrical requirements are 220/440 volts, accommodating multiple facility specifications. This robust manual lathe is suitable for job shops, maintenance facilities, and production environments requiring reliable, precise machining of large-diameter components with consistent repeatability and minimal runout.
