Overview

Heller TGPB820 large-bore lathe

The TGPB820 (205/225/255)x1500-3000 large-bore lathe is designed for machining long, large-diameter workpieces with high accuracy and consistent performance. It has a bar capacity of between 205 and 255 mm and a distance between centres of 1500 to 3000 mm, which makes it possible to work with long, heavy components without losing stability. Its monobloc cast iron bed, 600 mm wide, ensures firm support and smooth carriage movement for precise finishes. Equipped with a Norton gearbox for feeds and threading, multiple spindle speeds and a powerful motor, it makes continuous, complex operations easier. It incorporates a coolant system, an adjustable hydraulic brake and a chuck guard, and complies with CE standards for a safe working environment. This model is ideal for industries that require accuracy, capacity and durability when turning long, large-diameter bars.
