The BigBore model (BB und BB+) of the box guideway-based Hi-TECH 550, Hi-TECH 700 and Hi-TECH 850 lathes is distinguished by its extra-large spindle bore (Big Bore), which permits diameters of 190 - 370 mm to be clamped in the spindle. In addition, the BigBore model has a widened turret which has two BMT tool holders, one behind the other. This means that long tools, which are often used for working inside pipes, can be optimally stabilised, significantly reducing vibration. The main spindle can also be equipped with two pneumatic chucks - one in the working space and the other at the rear of the spindle. This allows pipes to be optimally supported in the spindle whilst also being fed in and unloaded from behind.

Horizontal lathe with BigBore spindle (295 - 370 mm) for tube machining

The main spindle can also be equipped with two pneumatic chucks - one in the working space and the other at the rear of the spindle. This allows pipes to be optimally supported in the spindle whilst also being fed in and unloaded from behind.

Thanks to the wide box guideways and high torque, which is achieved by means of a high-power drive and gears, the Hi-TECH BB series is ahead of the pack in terms of stability, reliability and performance.
