What make a Factory Acceptance Test (FAT) so valuable?
I recently attended a successful Factory Acceptance Test (FAT) for the electromechanical ADE actuators that we supply during the renovation of the...

Fast, dynamic and powerfull are some of the highlights of the new WEISS TO torque range rotary tables. The introduction of a high-tech drive that operates predominantly without mechanics or gearboxes is the logical response to changing market requirements and customer wishes. However, until now these direct-drive tables were limited to a diameter of 750 mm. But this has all changed with introduction of the TO1300, which suddenly makes applications possible that previously seemed out of reach.
The newly developped WEISS TO 1300 resulted from concrete customer requirements. The criteria set were:
A mechanical heavy duty table (eg WEISS CR) is typically the right choice for tasks of this nature. However, due to their gearing ratio, these tables do not fare well in service life calculations for use at such high speeds. The needle bearings simply suffer from too much wear. The alternative is direct drive, which also heralded the birth of the TO1300.
With direct drive, only one bearing is under load and this is virtually free of backlash. The table is low-wear and easily capable of delivering the desired dynamic performance. In addition to this, its ability to cover a significantly more versatile range of tasks - including repeat use - allows customers to tap new added value potential.
