used machine

STAR SB-20R type G CNC turning centre was manufactured in 2014 in Japan. The machine is distinguished from other machines of its type by its compact size and a range of features that allow it to perform virtually any type of machining on workpieces with a maximum diameter of 20 mm. The maximally durable and rigid design additionally ensures the incredible stability and rigidity of the process, required to achieve excellent turning precision and quality.

Inside the large working area there are two spindles (main spindle and sub-spindle) with C-axis, which are driven by reliable high-power motors. The sub-spindle, in combination with the driven tools, allows completely independent machining after capture. The lathe also features a revolutionary guide sleeve change system, which allows the machine to switch between guide sleeve and no guide sleeve mode.

The STAR SB20R type G Swiss-type automatic lathe has so far only machined parts made of brass and is not worn out. The offer comes with extensive equipment, including an FMB turbo 2-20 / 4200 A bar feeder, a 6-station 12×12 mm knife vice and an intuitive FANUC Series 0i-TD CNC control. The CNC twin-spindle lathe weighs 1750 kg.
